Green Frog (true frog family)

Order Anura, Family Ranidae. These are typical frogs with adults being truly amphibious, living at the edge of water bodies and entering the water to catch prey, flee danger, and spawn. This profile covers medium-sized ranids. Also, all frogs are somewhat poisonous to some degree, but most of them aren't harmful to humans.

Description

The green frog (Rana clamitans) is usually found near shallow freshwater throughout much of eastern North America. Two subspecies are recognized: R. c. clamitans (the bronze frog; ranges from the Carolinas to northern Florida, west to eastern Texas, and north along the Mississippi Valley to the mouth of the Ohio River). However, the R. c. melanota (the green frog; ranges from southeastern Canada to North Carolina, west to Minnesota and Oklahoma but rare in much of Illinois and Indiana, introduced into British Columbia, Washington, and Utah.

Body Size

The green frog is a medium-sized ranid usually between 5.7 and 8.9 cm snout-to-vent length. Its growing period is mainly confined to the period between mid-May and mid-September. But the females are generally larger than males. But the adults typically weigh between 30 and 70 g. The average lifespan of Green Frog is approximately 16 years, fairly long compared with other frogs.

Habitat

Adult green frogs live at the margins of permanent or semi-permanent shallow water, springs, swamps, streams, ponds, and lakes. Green frogs primarily to inhabitant the banks of streams. They also can be found among rotting debris of fallen trees. Juveniles prefer shallower aquatic habitats with denser vegetation than those preferred by adults. Moreover, Green frogs inhabited aquatic habitats about two-thirds of the time and terrestrial habitats the remaining time. The green frog relies on terrestrial habitats for feeding and aquatic habitats for refuge from desiccation, temperature extremes, and enemies. Ponds used by green frogs are usually more permanent than those used by other anuran species.

Food Habits

Adult R. clamitansare terrestrial feeders among shoreline vegetation. They consume insects, worms, small fish, crayfish, other crustaceans, newts, spiders, small frogs, and molluscs. The terrestrial beetles often are their most important food item but noted that any locally abundant insect along the shoreline may be consumed in large numbers. There is a pronounced reduction in food consumption during the breeding period for both males and females. During the breeding season, males spend most of their energy defending breeding territories, and

Green Frog females expend their energy producing eggs. Fat reserves acquired during the rebreeding period compensate for reduced food intake during the breeding period. Also, green frogs consume most of their food in the spring and eat little during the winter. Food eaten in the spring, summer, and fall consists mostly of terrestrial prey.  whereas winter food is composed mostly of aquatic prey.

Juveniles (sexually immature frogs) eat about half the volume of food as do adults over the course of a year. Green frogs eat their cast skins following molting; the casting of skin is frequent during midsummer.

Temperature regulation and daily activities. Green frog's activity period varies by frog size, with larger frogs being primarily nocturnal, small frogs being diurnal, and middle-sized frogs (5 to 7 cm SVL) being equally active during day and night.

Hibernation

Adult green frogs overwinter by hibernating underground or underwater from fall to spring. The frogs hibernating in mud and debris at the bottom of streams approximately 1 m deep. The adults usually hibernate in restricted chambers within rock piles or beneath plant debris, while juveniles are more often found in locations with access to passing prey. The frogs begin emerging when the mean daily temperature is about 4.4C and the maximum temperature is about 15.6C for 3 to 4 days. Juvenile frogs enter and exit hibernation after adult frogs.

Breeding activities and social organization

Green frogs breed from spring through the summer, spawning at night. Female green frogs stay in a nonbreeding habitat until it is time to spawn. In preparation for breeding, males establish territories near the shore that serve as areas for sexual display and as defended oviposition sites. Males establish calling sites within their territories where they attempt to attract females. Females visit male territories to mate and lay their egg masses. The masses are contained in films of jelly and are deposited in emergent, floating, or submerged vegetation; they hatch in about 3 to 6 days. Adults are solitary during non-breeding periods.

In the southern part of their range, green frog tadpoles metamorphose into frogs in the same season in which they hatched, while in the northern part, 1 or 2 years pass before metamorphosis. Tadpoles that hatch from egg masses laid in the spring usually metamorphose that fall, while those hatching from summer-laid eggs typically overwinter as larvae and metamorphose the following spring. 

The most tadpoles are 2.6 to 3.8 cm SVL at the time of transformation. Those that transform in late June or early July grow rapidly, adding 1.4 to 2.0 cm SVL in the first 2 months and 0.4 to 0.7 cm SVL more before hibernation. Tadpoles that transform at approximately 3.1 cm SVL may reach between 5.0 and 5.8 cm SVL before hibernation. Therefore, newly transformed frogs often move from lakes and ponds where they were tadpoles to shallow stream banks, usually during periods of rain.

Home range and resources

The species' home range includes its foraging and refuge areas in and around aquatic environments. During the breeding period, the male's home range also includes its breeding territory. It is roughly 80 percent of adult frogs captured in the spring and again in the fall occupied the same home ranges.

Population density

During the breeding season, green frog densities at breeding ponds can exceed several hundred individuals per hectare. Adult male frogs space their breeding territories about 2 to 3 m apart. The sexual maturity is attained in 1 or 2 years after metamorphosis; individuals may reach maturity at the end of the first year but not attempt to breed until the next year. Most females lay one clutch per year, although some may lay two clutches, about 3 to 4 weeks apart. In natural populations, green frogs can live to approximately 5 years of age.

Similar Species

1.       The river frog (Rana heckscheri) is slightly larger than the green frog (8.0 to 12.0 cm SVL) and is found in swamps from southeast North Carolina to central Florida and southern Mississippi.

2.       The leopard and pickerel frogs (Rana pipiens and its relatives, and Rana palustris) are medium-sized and strongly spotted. There are four leopard frogs whose ranges are mostly exclusive from each other but overlap with the green frog. The pickerel frog has a similar range with gaps in the upper Midwest and the southeast.

3.       The mink frog (Rana septentrionalis) is only slightly smaller (4.0 to 7.0 cm) and is found on the borders of ponds and lakes, especially near waterlilies. It ranges from Minnesota to New York, north to Labrador.

4.       The carpenter frog (Rana virgatipes) is about the same size as the green frog (4.1 to 6.7 cm) and is closely associated with sphagnum bogs and grasslands. It has a coastal plain range from New Jersey to Georgia and Florida. The bullfrog and pig frog are much larger ranid species.

The Honey Bees are Beneficial

Of the many tiny animals that share the planet earth with us. However, there are only a few insects that people usually accept as beneficial. The most are regarded as disgusting or frightful.  Insects often garner a bad reputation because of their unfamiliar appearance and habits. Honey bees are, maybe the insects with the best public image.

We see them as industrious (busy as a bee) and we appreciate their main product, honey, as setting the standard for all that is ecstatically wonderful and sweet.  Honey is only likely because thousands of bees harvest the nectar from flowers converting the sugary liquid to enjoyable honey.  And honey bees pollinate a vast variety of food crops.

Honey Bees Types?

In general, bees can be separated into two groups, the bees which are naturally social insects, and the ones which are solitary. All bees collect nectar and pollen and make honey, but the solitary bees make only enough honey for themselves and their progeny. Each mated solitary bee makes a nest with approximately ten brood cells.

The social bees, such as the European honeybee, make large stocks of honey, most of which can be removed without damaging the viability of the hive. Solitary bees make their homes in twigs, in the ground, on adobe walls, in mud, in locations where other animals have already made holes, in wood, cardboard, another material.

Most solitary bees overwinter in their nests and re-emerge in the spring when temperatures and other climatic conditions are appropriate for their spring activity. Almost all the genera of solitary bees are beneficial for fruit crops

Why We Love Honey?

Honey is a healthy food as enthusiast sees honey as an alternative to sugar. Many home remedy proponents extol the use of honey as a cure for various ailments.  We even call our loved ones Honey as a term of endearment. The Quran is full of positive references to honey. 

The Bible says (the land of milk and honey) and several ancient and modern works refer to bees and honey. Prehistoric cave drawings show people harvesting honey from wild bee colonies and ancient Egyptian hieroglyphics depict early beekeeping activities. With the good and sweet there is a down side people get stung sometimes. Even Winnie the Pooh found that bees could get a little nasty when disturbed.

But, in general, bees and their honey have a long and well-established history of acceptance and respect. In agro forestry techniques such as windbreaks, alley cropping, and riparian buffer strips, tree and shrub species can be selected to favor bee forage. Raising honeybees in forests, windbreaks, tree alleys and riparian buffer strips improves the direct economic return from applying these management techniques.

Honey Bees are Important Pollinators

While honey is nice, the honey bee’s real importance lies in its performance as a pollinator. The value of just the almonds produced in California each year with the help of honey bees is more than twice the value of all the honey produced in the United States in any given year.

The apple and blueberry, watermelon, cantaloupe, cucumber, cranberry and many other crops benefit from bee pollination.  More than 100 agricultural crops in the United States are pollinated by bees.  About a third of the food Americans eat comes directly from the pollination honey bees perform.

Moreover, heritable behavioral polymorphisms of the honey bee, such as pollen-hoarding, can enhance fruit and seed set by a floral host (e.g. cranberry). But only if more favored pollen hosts are absent or infrequent. Then, honey bees' broad polylactic, flight range, and daily idiosyncrasies in floral fidelity will obscure specific pollen-foraging differences at a given floral host, even among paired colonies in a seemingly uniform agricultural setting. It has been estimated that every third bite of food is dependent, directly or indirectly, on the active pollination of a food plant.

The Killer Bees (AHB)

Some of the tales stated about this bee are incredible.  The Africanized honey bee (AHB) or killer bee as it is sometimes called, is said to attack for no good reason. This is a bee that is hard to handle for beekeepers who want to move colonies around to pollinate various crops.  Stories suggest that the AHB often invades the unmanaged colonies of normal bees and takes them over in a sort of insect blitzkrieg.

The AHB or killer bee has been depicted in science fiction movies like “The Swarm,” “The Savage Bees” and in the Fox TV movie “Deadly Invasion.  The Killer Bee Nightmare, “threatening our lives, our property, and our whole way of life. There is no question this bee is more defensive as well as aggressive to protecting its home and beekeepers and others have gotten stung multiple times in accidents.

Irrespective of myths to the contrary, Africanized honey bees do not fly out in angry swarms to arbitrarily attack unsuccessful victims. Monitoring with bees allows us also to evidence the application of molecules, not permitted under certain circumstances or even forbidden.

Honey Bees Poisoning Symptoms

The most shared symptom of bee poisoning is the appearance of excessive numbers of dead bees in front of the hives. Another common symptom is lack of foraging bees. Ferociousness in bees may be caused by most pesticides. Stupefaction, paralysis, and abnormal activities of bees are usually caused by chlorinated hydrocarbons and organ phosphorus insecticides.

Regurgitation of the honey stomach contents is often caused by poisoning with organo phosphorus insecticides. Bees may perform abnormal communication dances on the horizontal landing board at the hive entrance while under the influence of insecticide poisoning. Disorganized behavior patterns may lead to lack of recognition of affected field bees by guard bees.

How Does Tsunami Formed

The peoples often think How Tsunami Occurs? The tsunami is a series of ocean waves, which carry water to the large, every now and then reaching heights of over 100 feet about 30.5 meters, to the earth. These walls of water can reason widespread destruction when it crashes countries. These gigantic waves generally caused by large underwater earthquake tectonic plate boundaries. When the bottom is flat limit add to or reduce suddenly moves above the water, and that will start the tsunami waves.

Most of the tsunami, 80 % occur in the Pacific “Ring of Fire”, a geologically active tectonic movements are regular in volcanoes and earthquakes. Tsunamis can also be reasoned by landslides or underwater volcanic eruptions. They can even be launched, as they were frequently in the ancient past of the Earth, with the result of a huge meteorite plunging into the ocean.

The tsunamis in the race to the sea up to 500 miles about 805 kilometers an hour as fast as a jet.  At that pace, can traverse the whole expanse of the Pacific Ocean, less than a day. And their long wavelengths mean that they lose very petite energy along the way. In the deep ocean, tsunami waves can come into sight only a foot or so high. But the move toward of the coast and enter shallower water, they slow down and start to grow in power and height.

Top of the waves move quicker than their funds do, causing them to rise sharply. Tsunami waves from the bottom, below the top of the lower wave, often arrive at the shore first. When it happens, it generates a vacuum effect that sucks the coastal sea water and exposed to the harbor and the sea floor. This withdrawal of sea water is a significant warning sign of a tsunami wave as crest factor, and the enormous amount of water usually hit the beach five minutes or so. To be familiar with this phenomenon can be lifesaving.

A tsunami usually consists of a series of waves, normally called a wave train, so destructive force may be compounded as consecutive waves reach the shore. People know that a tsunami should keep in mind that the risk is not past the first wave and would need an official notification that it is secure to vulnerable sites. A few tsunamis are not on the coast as gigantic breaking waves, but more like a tidal surge flooding quickly in coastal areas.

The most excellent defense against a tsunami early warning that permits people to seek higher ground. The Tsunami Warning System, a coalition of 26 nations headquartered in Hawaii, maintains a network of tide gauges and seismic equipment to recognize tsunamis at sea similar systems have been projected to protect coastal areas in the world. Read More – Spectacular Golden Chains of Laburnum

The Baya Weaver Bird (Ploceus philippinus)

The variety that builds the more elaborate nest is the Baya (Ploceusp. philippinus). The Baya Weaver Bird is also found all over the subcontinent, Java, and Sumatra. The male resembles the female during the "off" season but after the spring and autumn molts, he assumes canary-colored crown and other yellow patches, well distributed over most of his otherwise brown and white body.

Baya Weaver Bird decoration loses when their is no nesting to occupy his attention. The bird’s flocks are found in scrub, grasslands, cultivated areas, and secondary growth. Also, these birds are best identified for hanging retort-shaped nests woven from leaves.  The Baya Weavers love to live and build in colonies and usually select for the purpose of the neighborhood of a convenient tank or of a terraced rice field.

Being graminivorous animals they find that paddy fields furnish valuable granaries for a food supply. The nests found in the Northern Province of Sri Lanka almost habitually hang from the north and east exposures of the trees. In which they built and thus are least endangered by the battering winds of the Southwest Monsoon.

Though, the much has been written about the amazing nests of Ploceus. They're are several interesting points connected with there construction that have escaped most observers or that do not appear to have impressed writers sufficiently and propose with the aid of a series of photographs taken in situ to point out some of these curious happenings.

While the Tailor Bird does her best to conceal her nest (in which she succeeds an admirably) the Weavers build there homes quite in the open where they can be seen of all men. They're are a number of nests in a colony that had settled in a large tree growing about the center of a Sri Lanka. They came and went as if no human being were near them.

Wherever placed the main objects sought shelter from bad weather and safety from enemies. These provisions are reflected in the suspension of the nests on the sheltered side of a tree on branches detached from other limbs and by the peculiar form and swinging character of the nesting houses.

They're is, however, one precaution always taken the nest hangs free in air and swings from the tree on which it is built in such fashion that it cannot be approached from below or from neighboring branches and when that end is accomplished the birds may suspend there nests from quite low points, often not more then fifteen feet from the ground.

The terminals of palm fronds and other branchlets about twenty feet from the earth, or surface of a pond, our favorite sites. According to some writers, the Weavers, instead of building a new nest once or twice a year, may repair an old one, the chief evidence of which is the color contrast between the nest and the Old grass employed in the process.

Indeed a tree colony of several dozen nests may exhibit at the same time a collection of structures that vary in age from old specimens battered by months of wind and rain to new and fresh nests on which the builders are still working. In some of the latter from one to four white eggs may be hatching; from others issue little chattering cries that betray the presence of hungry fledglings.

The shape of the Ploceine nest has been likened to various objects retorts, inverted bottles, flasks, etc. But to Newton's similitude comes nearest to it.' He compares it to a stocking hung up by the toe, the heel enlarged to receive the eggs, as entrance and exit are made through the leg. The material out of which the nests are made is mostly pliant grass stems and other tough fibers, especially strips of palm fronds.

The bird's strip from the leaves of palms, plantains, agaves, and other stringy plants fine but very strong threads for the weaving process. The bird collects them in this manner. Usually, bird bites a small piece from the base of the palm, sisal, hemp, or another fibrous plant, repeats the incision towards jerks his head away from the leaf, thus tearing off a fine cord, perhaps a line in breadth that corresponding length to the distance between the two incisions.

It examined with a lens this weaving material from many nests and believes the description to be most accurate. Moreover, watched the birds repairing the exterior and arranging the material of there nests and have often seen them tugging at a length of the fiber, part of which has already been woven into the nest. Also seen them flying in the air with the free end of a strand in there bills, so that it might be drawn taut and smooth before inserting it beneath other fibers for the support of the nest wall.

As a preliminary to the construction of the nest proper, the birds wrap a considerable amount of fibrous material around a chosen limb or frond. Often it is as much as three or four feet from the top of the pendant next to the further end of this anchorage, thus securing a firm hold upon the tree. The small strips are not only wound around the branch but are plaited together so securely that it is impossible with an ordinary effort to separate them.

The plaiting is than continuous downwards from the branch to form a stout aerial stalk from 3 or 4 inches to a foot in length. The end of which is evidently expanded into the globular structure of the nest proper. The long diameter of this bulb is from 5 to 6 inches; it's short diameter about four.

Having shaped this upper chamber and located the future egg chain bet, the birds next build a strong, compactly woven transverse band or bridge that divides the lower part of the space into two unequal chambers. In every large colony are found what looks like unfinished nests that do not in the building get farther then this perch or roost stage, looking, like an inverted basket with a handle.

So far as they go, these structures seem strong and well-finished, giving rise to many speculations as to there status. Are they made in an excess of home-building zeal by the male bird upon who's feet and beak time hangs heavily? Or, are they shelters to which he may retreat and rest secure from the torrential Monsoon?

The main argument favoring this hypothesis is of course. The finished appearance in various cases of the canopy itself, it's thick, smoothly plaited walls. Hence, the rounded edges of the perch, and absence of any attempt to completing the base of the globular chambers or the entrances pout. It is suggested that the canopy is a nest deserted after partial construction on account of some fault in it an egg chamber too small, a neck not strong enough, etc.

Whether the canopy is deliberately planned as a shelter for one or both birds, or whether it is only a partially built and deserted nest, their can be no doubt that the non-incubating male has been seen occupying the structure and using it as a perching convenience and their is no doubt that, whatever the original purpose of these structures, the canopy does make an admirable refuge from wind, rain and hot sun.

The illustrations show more plainly then any description of the forms and the relative size of the completed nests and so-called canopies both before and after removal from the tree-colony. One colony, placed in a Halamba tree, furnished four canopies, as well as two full-lengths and one short nest. On the ground beneath the tree were picked up evidently detached by the wind--five full length and two short-tube nests.

In another tree, it can be found seven canopies and five nests. Three egg chambers held a single egg and two had two eggs each. All the canopies had, on or near there margins. Farther the small lumps of dried mud, about which something farther will be said; on the other hand, very few nests showed these deposits. The lowest structure was 12 feet from the ground. The average was 16 feet and the highest about 25 feet.

A small but for many reasons interesting colony had nested in a Damba tree. It numbered two canopies one definitely unfinished nest, one long (with it's entrance tube fifteen inches) and two completed but shorter nests. The long nest contained fledgling’s inches.

The length of the shortest tube was 3 inches; the others varied from 6 to 15 inches.  The circumference of the smallest nest was 14 inches; of the largest 18.50 inches. The longest nest measured, overall, 37 inches; the shortest 17 inches.

As for the four canopies, the total length of the shortest was 12.75 inches; of the longest, 16.50 inches. The height of the chamber varied from 4 to 6.50 inches. Thus the width of the bridge or perch is one half to one inch. The diameters are the two entrances from 2.25 by 3.75 inches to 3.50 by 2.50 Inches.

The circumference of the largest canopy was 20 inches; of the smallest 15 inches. Hence one sees that the nests and canopies vary noticeably in size and capacity. The smaller of the two cavities divided by the transverse roost or perch is the one continued into the long tube-like entrance. As soon as when the egg-chambers finished. Female bird confines her concentration to the completion of the interior of the nest and leaves the work on it's exterior to the male.

They seem to work together, although the male gathers most of the building material which he pushes through the walls. It is than woven back and forth as long as possible that is until thick, tough, solid, basket-like walls are the result. The male bird now completes the entrance-spout strengthens the walls of the upper nest and, in some instances begins a second nest like the structure already mentioned. During the nest building, both birds enjoy them thoroughly.

Also, the male bird often sings a little song when he joins with his mate in weaving the nest material. Even after the eggs have been laid and the female has commenced incubating the male continues to lengthen the entrance tube and to put what he regards as the finishing touches on his house.

Also, it is often seen him diligently pushing fibers into place and pulling them back and forth on the surface of the nest to the accompaniment of a sweet little warble. I have never found a smooth firm margin on the end of any entrance tube; it is always frayed, thin and loosely woven, presenting a decidedly unfinished appearance.

The length of the cylindrical entrance tube--generally two inches in diameter varies greatly, as will be seen in the illustrations. Indeed the longest one I ever saw was in the private aviary of Mr. Shore-Bailey of Westbury, England, who has been very successful in breeding these birds in captivity. One of his nests has the entrance tube more then thirty inches long.

The length, strength, and thickness of the various external components of the Weaver Bird's nest depend largely upon the building capacity of the male bird. As with male humanity, this varies greatly. Long after the female begins to sit he may continue his task of nest building. If he is possessed of the building urge he strengthens the attachment of the structure to the tree above, adding more strands of fiber to and lengthening the rope that is already wound about the branch above.

This suspension cord is also increased in sustaining power by short fibers of palm or agave, plaited with strands already in position; and the walls of the nest chambers themselves are consolidated by similar material worked into there thickness. Meantime the tubular entrance is extended and the upper two-thirds of it farther strengthened.

When the young birds are first hatched they are probably fed by the parents with food brought in by way of the long tube but in some instances, at least, opening remade by the male bird from the outside directly into the egg chamber and the fledglings re-fed through these holes. One of the most fascinating habits of the Baya is the manner in which he enters and leaves the nest. I have watched the process many times and have always gazed in wonderment.

Even the so-called Chimney Swift entering his home may learn something from a bird that, apparently without agitating the shaky structure of his domicile flies up to the narrow chimney-like structure and out again without hesitation. I have seen the male in the midst of a job of repairing the roof suddenly take it into his head to visit his brooding wife. Flying or tumbling down the side of the nest he spread his wings just in time to stop his fall a foot or two below the entrance. Apparently, without effort, he turned in midair and shot, like lightning, into the cylinder above him.

Some do not believe any other bird could have done it. Legge, who has wings at the moment of entering the tube and runs up it to the egg chamber. Be that as it may, Ploceusis secure in his home, for he is certainly the only animal that can fly, crawl, run, or creep up the smooth, fragile, tube that leads to the interior of his nest. The completed nest is a firm springy contrivance and so well woven that when thoroughly dried it is used by the natives for filling mattresses.

Sometimes during nest building, the birds bring in small lumps of wet clay which they stick to a variety of parts of the interior of the nest and it's walls. So, it found curious deposits in varying quantities in almost all the nests examined. One had about a tablespoonful of plastic mud deposited on three diverse localities, including one small patch in the egg chamber. On the other hand, a few had no mud deposits and others had very little. Just what these clay deposits mean is by no means clear.

Indeed none of the numerous explanations is satisfactory, especially reject the generally accepted theory that the mud is employed to balance the nest in the wind, and to prevent it's being blown about while tile birds are entering and leaving it; nor can I adopt Layard's guess that tile birds use the clay as a sort of whetstone on which to sharpen there bills. In the first place, half a tablespoon of dried mud plastered midway of a large and longs winging nest can have no influence whatever upon it's equilibrium in even a mild breeze.

Than again, many nests have no mud in there structure at all. Of course, the natives, as usual, have there interpretation of the phenomenon--the bird uses the clay as a candlestick on which is stuck glowworms to lighten the darkness of the nest! Perhaps I may add another and to my mind more plausible theory-•-the habit is the survival in Ploceus of some ancestor who built his nest partly or entirely of clay.

The black clay deposits in Baya's nest, than serve no useful purpose at all. They are just vestigial remains of a household economy, as the sleeve buttons on one's coat! One is reminded of stone what similar example in the habits of birds completely unrelated to the Weaver. But this genus is in an evolutionary sense flanked on the one hand by genera (Micropus, Taehornisw) hose nest material is partly mucus and partly other material, and on the other by genera who's nests have little or no mucoid matter in there makeup.

However that may be, our Weaver Bird is a highly intelligent animal, and whether one attributes his remarkable house-building to instinct, to reason, or, as is most probable, to a combination of these faculties, he makes a very attractive captive and an engaging presence in an aviary large enough to afford him plenty of room in which to build and breed.

He is, though, impatient of avian relatives, and is very likely to quarrel with other birds placed with him in the same flight. T. B. Fletcher (Birds of an Indian Garden, 1924) tells us that Among the natives of Punjab a popular rhyme contrasts the helpless monkey with the resourceful; house-building Weaver.

In that, the former cannot protect himself from the weather in spite of his human hands and feet. This verse is quoted for the benefit of small boys and girls who object to learn, just as the busy bee is held up for infantile admiration of Western lands."

What are Drunken Trees

What are Drunken Trees?

Drunken trees are a stand of trees displaced from their normal vertical alignment. This most commonly occurs in northern subarctic taiga forests of black spruce under which intermittent permafrost or ice wedges have melted, causing trees to tilt at various angles. Some trees survive their soil eroding and continue to grow. Others collapse or drown as the subterranean ice melts. As they are staggered across the landscape, people often refer to them as 'drunken trees.'

Drunken Trees are also called, tilted trees or a drunken forest may also be caused by frost heaving, and subsequent palsa development, hummocks, earth flows, forested active rock glaciers, landslides, or earthquakes. In stands of spruce trees of equal age that germinated in the permafrost active layer after a fire. They tilting begin when the trees are 50 to 100 years old, suggesting that surface heaving from new permafrost aggradation can also create drunken forests.

What is Permafrost?

Permafrost soil or rock remains below 0 °C for at least two consecutive years. It forms a solid matrix in the soil which can spread to a depth of hundreds of meters. Permafrost is permanently frozen ground. Nonetheless, climate change has caused much of that ground to melt at an unprecedented rate. The ground buckles and sinks, causing trees to list at extreme angles. Further, the permafrost prevents trees from developing deep root systems. Also, those areas where the permafrost temperature is close to the melting point of water.

Drunken Trees Relations with Climate Change

The climate variations, or loss of surface vegetation from fire, flooding, construction, or deforestation, can thaw the upper extents of the permafrost. This is creating a thermokarst, “the scientific name for a ground slump caused by melting permafrost”. The thermokarst undermines the shallow root bed of trees, triggering them to lean or fall. Thermokarst lakes are enclosed by a ring of drunken trees leaning toward the lake, which makes this land features simply identifiable. When permafrost melts, it affects a lot of erosion; a lot of trees can't stand up straight. If the erosion gets worse, everything goes with it.

Drunken trees may ultimately die from their displacement, and in ice-rich permafrost. The entire drunken forest ecosystem can be damaged by melting. Drunken trees are not totally new phenomenon dendrochronological evidence can date thermokarst tilting back to at least the 19th century. Permafrost is naturally in disequilibrium with climate, and much of the permafrost that remains is in a relict state. However, the rate of thawing has been increasing, and a great deal of the remaining permafrost is expected to thaw during the 21st century. At times the trees survive the pressure and continue growing, uprighting themselves to vertical. However, on the other side, trees collapsed or drown from rising water tables as subterranean ice melts. Because such trees seem to stagger across the landscape, people often call them "drunken trees."

Moreover, Al Gore cited drunken trees caused by melting permafrost in Alaska. This is as another evidence of global warming, as part of his presentation in the 2006 documentary film An Inconvenient Truth. Alike warming leading to permafrost thawing in neighboring Siberia has been credited to a combination of anthropogenic climate change, a cyclical atmospheric phenomenon known as the Arctic oscillation.

Moreover, the albedo positive feedbacks caused by both when melting ice expose bare ground and ocean which absorb, rather than reflect, solar radiation.  The melting permafrost isn’t just affecting the trees. But it is also having an enormous impact on the people that live and work in the zone. Thus, slumping land cracks pavement breaks pipelines, and causes sinkholes to open, swallowing roads, and buildings. Source: CP

Crop Circles! Forest Experiment in Making of Half a Century

Have you ever listened about Crop Circles? In the recent times, Crop Circles have spotted in Japan’s Miyazaki Prefecture. This experimental forest in Japan is creating quite a stir with its unique shape. They were formed by Japanese Cedar Trees, only viewable from above. The incredible photos of geometric designs emerged in a large mature forest. The researchers are confused to learn how these shaped emerged? The practical explanation was the result of a scientific experiment that spanned half a century.

The scenic natural formations aren’t the results of an alien invasion, but rather a well thought out a preplanned imitative. Back in 1973, Japan’s Forestry and Fisheries (Ministry of Agriculture) started a project dedicated an area of land near Nichinan City was making an ‘experimental forestry’.  The scientist planted circles of cedars with smaller inner circles expanding incrementally into larger radiuses to create 10 perfect rings. One of the experiments was to try and measure the effect of tree spacing on growth. The experiment was carried out by planting trees in 10-degree radial circles of varying diameters.

The Crop Circles are so attractive due to their concave shape.  It was an unexpected result of the experiment that would recommend tree density does indeed affect growth. The trees are due to be harvested almost five years but officials are now considering preserving the crop circles. These images are efforts of Google Earth, however, these are very dark. The more space equals less competition for resources such as water and sunlight. Hence, it’s easier for these outer trees to grow bigger and stronger while those on the inside fight it out amongst themselves.

The Incredible Rectangular Iceberg Floating Off Antarctica

Nature follows their own rules and laws, but sometimes results are often irregular and asymmetric like clouds and coastline and ocean waves. NASA scientists Jeremy Harbeck & his team were flying over the northern Antarctic Peninsula as part of Operation in October 2018. They saw an incredible IceBridge spotted precisely cut rectangular piece of the iceberg floating amidst a jumble of broken ice, everybody thought it was pretty interesting.

 

Because such type of rectangular formation is called a “tabular iceberg”. It's a supernatural occurrence; it's amazing, but nothing out of ordinary. I had seen many icebergs around Antarctica that have very straight, very long sides," he said. These tabular icebergs are wide and flat, and long, like a sheet cake.

Thus the ice breaks according to its crystalline structure in a straight line. The walls of this new iceberg are sharp and almost perfectly vertical, suggesting they formed recently. As time goes on, waves will start to erode these edges, creating large arches and caving in its walls. The cold air and sea temperatures mean they melt slowly, and large icebergs can survive for many years.

Normally icebergs with relatively straight edges are common, this was the first time anybody has seen an iceberg with two corners at right angles. They split from the edges of ice shelves like fingernails breaking off when they grow too long. The iceberg will also continue to break and crack, losing chunks of ice around the edge, and possibly even fragmenting into smaller pieces. These fracture lines can form interesting geometric structures like rectangles and triangles.

We often see icebergs with geometric shapes, although such a perfect rectangle is admittedly unusual. This specific rectangular iceberg is about one mile wide, and it had just broken off from the Larsen C ice shelf. NASA aims to better understand the connection between earth’s polar regions and the global climate. In spite of its eerily perfect shape, this iceberg is completely natural, and in fact not even that unusual. The largest iceberg ever observed, named B-15, was released from Antarctica in 2000, and some fragments of it still exist today near the island of South Georgia.
