The bottle is made from switch grass, pine bark, corn husks and other materials. Ultimately, Pepsi plans to also use orange peels, oat hulls, potato scraps and other leftovers from its food business.

The call of the prairie dog is thought to sound like the bark of a dog but given its small size the tone of its bark only matches that of the smallest true dogs.

With wingspans reaching up to about 4. 5 feet (1. 4 meters) wide these animals can grow to be as large as a fox.

and peeling bark during periods of dry windy weather can turn a small ground fire into a terrifying explosive firestorm in a matter of minutes.

If the tree straightens with the straw still wedged in one of these cracks it might appear as though the straw pierced the bark of the tree.

They typically live in rotting holes in the bark and build silk trip wires outside the holes to alert themselves to prey.

and bits of bark are used to disguise the entrance. Their dwellings have been found as much as 30 meters off the ground.

and though they have a number of common characteristics including distinctive cinnamon-red bark they are different species. One giant sequoia (Sequoiadendron giganteum) known as General Sherman is the world's largest tree

Protected by bark up to 3 feet (90 centimeters) thick sequoias also drop their lower branches

which kill trees in the process of laying their eggs under the bark. Climate change has made the high-elevation whitebark pines more accessible to the destructive beetles.

and juniper mint cinnamon bark and other herbs flavored it. The jars were remarkably consistent in their contents suggesting that winemakers were sticking to a recipe.

In fire-prone areas the big trees that survived the fire have thick bark and high branches that protected them Skinner said.

which protect the tree bark and branches. So as we're climbing we're not digging the rope into the tree branch

and heat goes through the bark killing the living tissue. A couple of years later the bark falls off revealing the wood and an injury to the tree.

When looking at the rings you see charcoal formation on the outside and a resin formation on the top that creates a dark spot said Richard Guyette director of the Tree Ring Lab at the University of Missouri.

The emerald ash borer which burrows beneath the bark of ash trees to feed on the water

It will stay under the bark so it's protected there. It will actually purge all the stomach contents of its gut

In the winter months they eat twigs bark and buds. While originally from Europe and Africa rabbits now call many places home.

They chisel a hole into the bark to reach inside with their thin flexible middle finger and extract beetle larvae.

The only bad luck they bring is to grubs hiding beneath the bark of a tree.

However temperatures under the tree bark could be two to seven degrees warmer than the air University of Minnesota ecologist Lee Frelich told Minnesota Public Radio.

Despite the insulating effects of bark There is a large area in northern MN that has a lot of ash trees that experiences temperatures cold enough to greatly limit the survival

With one clean stroke he sliced a fuzzy fern off the bark of a nearby palm tree carried it back to the hut

The bees build these multilayered nest cells in secure locations near the ground such as under the bark of dead trees in stems

and like to hide under rotting bark logs and rocks during the day. They enjoy man-made habitats too such as woodlots abandoned buildings and barns.

We took turns squishing the mud spreading it on the bark of a nearby tree

Trees store carbon in their tissues such as wood bark and leaves. So scientists assumed the older trees were growing more slowly

but the biggest oldest trees can swell their wood bark and leaf mass by 1300 lbs.

#19 New Swift & Clever Praying mantises Discovered Swift deadly hunters lurk in the trees many camouflaged to look like lichen or bark.

Svenson discovered the new mantises part of a group called bark mantises in museum collections and in tropical forests.

or development encroached on habitat. 6 Strange Species Discovered in Museums Neotropical bark mantises live on tree branches

The mantises have flattened mottled bodies that mimic bark moss lichen or dead leaves. They fly poorly so their last line of escape is to leap to the ground

By looking at a cross-section cut through the bark of a tree scientists can count up the rings

Corks are made from the bark of Quercus suber trees commonly called cork oaks which grow only in southwest Europe and northwest Africa.

More and more low-quality cork trees with thin bark are sprouting up. 6 Unexpected Effects of Climate Change Now scientists think rising temperatures

and increased exposure to ultraviolet or UV light brought on by climate change may be behind chemical changes in the bark of cork oaks.

The change in bark quality may be the trees'way of adapting. Bark acts as the protective outer layer on trees that protects the plant from drought and shields against radiation.

Cork oaks have been growing thinner and more porous layers of bark. Cork producers need bark that's at least 27 millimeters (1 inch) thick to make a good cork

but most of the trees are now producing bark between 3 mm and 10 mm (0. 1 inches and 0. 4 inches) Teixeira and colleagues write in their study

To figure out what might be causing the changes Teixeira and a team of researchers analyzed genes in the bark of five high-quality cork trees and five low-quality cork trees growing in Portugal.

The scientists discovered that heat shock proteins are essential to the bark of high-quality cork trees. These proteins help the tree grow normally even under stressful conditions like drought

and high temperatures and promote cell division that makes the bark grow thicker. Bad cork trees have fewer of these shock proteins

but they have more genes that produce huge amounts of phenolic compounds UV-absorbing chemicals that collect inside the bark.

The researchers also discovered that the trees with thin layers of bark have lots of lenticular channels small airways that allow gas exchange between the bark and the outside air.

Corks made from this kind of bark are considered low quality because the lenticular channels allow more air to enter the bottle.

In the future it may even be possible to genetically engineer cork oaks with high-quality bark.

which even in winter have some carbohydrates mostly sucrose) in the vascular tissue beneath their bark had been gnawed by rats all the way around the base of the trunk a practice called girdling that usually kills a tree.

Elephants eat grasses roots fruit and bark. They use their tusks to pull the bark from trees

and dig roots out of the ground. An elephant has an appetite that matches its size.

A couple of degrees warming can make the difference between a stately shade tree and a sad bedraggled specimen with dead branches sparse leaves and grimy scale-encrusted bark.

Carbon dating tests showed that the vessel was last caulked with wads of bark in 1400.

Cashew nut oil as well as the leaves and bark of the cashew tree have also been used in traditional medicines in communities around the world to treat everything from toothaches to diabetes.

They usually eat vegetation such as wild celery shoots roots fruit tree bark and tree pulp but they have been known to eat small animals and insects.

As the burrowing beetles tunnel under the bark to feed and lay eggs, they release spores of the blue-stain fungus (Grosmannia clavigera),

or a moth's almost perfect mimicry of tree bark. In some snails, however, it's simply down to a poor fit with a snake's jaw.

just as the organic grocery stores and adventurous Japanese fusion tapas restaurants come to gentrifying neighborhoods. A smartphone ecosystem is not unlike a neighborhood:

Some trees that were right below the blast were still there looking like telephone poles with no bark

The president's 21-page climate change initiative has been a long time coming for many who felt that Obama's rhetoric on climate change has been more bark than bite.

That's what their fast-burning pine twigs and thick bark evolved for. Logging has people there on the ground clearing the brush taking away the kindling that turns each forest in the country into a powder keg.

Some trees that were right below the blast were still there looking like telephone poles with no bark

which is visible through a more pronounced red coloration of the wood beneath the bark.

#Slippery bark protects trees from pine beetle attacktrees with smoother bark are better at repelling attacks by mountain pine beetles

The tiny beetles which are about the size of a grain of rice bore into the pine bark.

Doctoral student Scott Ferrenberg who led the study said he first began to suspect that bark texture might affect the survival of trees

They noticed that surface resin a residue of fighting off a beetle invasion was common only on patches of rough bark.

To determine which was the case the researchers tested how well the beetles could hold onto different bark textures.

They placed each of 22 beetles on a rough patch of bark and on a smooth patch.

Twenty-one of the 22 beetles were able to cling to the rough bark until the test ended after five minutes.

But all of the beetles fell from the smooth bark in less than a minute. The results--especially combined with the findings of a second study also recently published by the research team--provide information that may be useful to land managers who are trying to keep public parks and other relatively small forested areas healthy.

Because young trees tend to have smoother bark as well as more resin ducts the research also suggests that land managers should consider cutting down some older trees

and painted all the holes they found in the bark of each tree--a different color each for large round woodpecker holes for the characteristic crescent-shaped holes mature emerald ash borers

and after the bark was stripped the students could identify woodpecker holes that penetrated into emerald ash borer galleries

the numbers of the predator in this case woodpeckers and other bark foraging birds increase either because they were moving into the area

and the white-breasted nuthatch the important bark foraging birds in this region increased as the emerald ash borer increased.

and bark used in traditional Chinese medicine. Some species are local endemics and Liquidambar chingii is listed as near-threatened by the IUCN.

Beginning at a tree trunk's dense core and moving out to the soft bark the passage of time is marked by concentric rings revealing chapters of the tree's history.

which attack the inner layers of bark feeding and breeding in the phloem a soft inner bark tissue

which impedes tree growth and eventually kills vast swaths of forest. Spruce beetles like their close relatives mountain pine beetles are attacking large areas of coniferous forests across the West.

--the downy woodpecker hairy woodpecker red-bellied woodpecker--as well as the white-breasted nuthatch a common bark-gleaning species that is also a potential predator of EAB.

The tree is harvested heavily for its leaves to feed cattle and for its bark which is used medicinally to treat many ailments from stomachaches to reducing malaria fevers.

which allow them to consume more tree bark and less fruit but they are still dependent on natural forests for their long term survival.

and other products in the United states use dried cassia bark or cassia cinnamon. Ceylon cinnamon contains very little coumarin a naturally occurring substance that has been linked to liver damage in people sensitive to the substance.

In addition to being a food source the bark and roots from fig trees are used for manufacturing items such as barkcloth handicrafts shields and buildings.

To study the expression of citrus srnas in response to HLB we grafted 19 greenhouse-grown healthy sweet orange plants with HLB-positive bark or leaf pieces.

The beetle invades a tree by landing on the bark and laying an egg. That larva will hatch

and penetrate into the tree feeding on the thin layer between the bark and the heartwood.

Instead weather and topography play a greater role in the ecological severity of fires than these bark-boring beetles.

Forests attacked by bark beetles --which burrow into the bark of lodgepole pines to mate and incubate their larvae--can seem nothing more than ample kindling for a raging blaze with their dead wood and dry reddish-brown needles.

The burrows the beetles carve under the bark of pines called galleries choke off water and nutrient circulation in the trees.

The trees die and for the first couple of years they hold on to their dry lifeless needles.

and stripped sections of bark from over 10000 trees to determine what killed them beetles

or Fire beetle galleries can remain visible under the bark even after fire. As they sifted through the blackened trees

and silt fines and 5%pine bark; a soil-based substrate (soil) composed of 50%sandy loam soil and 50%pine bark;

and a slate-based substrate (slate) composed of 80%expanded slate and 20%pine bark.

The substrates differed in infiltration and drainage rates as well as chemical composition. Diverse plant species that included trees shrubs herbaceous perennials a grass and a rush were selected to allow the researchers to evaluate the performance of a wide range of evergreen deciduous woody and herbaceous plants.

and even its colorful bark now has a disease problem--although so far only in the commercial nursery setting.

Research has demonstrated that firewood harbors many bark-and wood-boring insects. In 2008 co-author Robert Haack of the Forest Service's Northern Research Station found that nearly 25 percent of firewood intercepted at the Mackinac bridge between Michigan's Upper

and Lower peninsulas carried live bark -and wood-boring insects and an additional 41 percent displayed evidence of prior borer infestation.

Chinese cinnamon (Cinnamonum cassia) and original Ceylon cinnamon (Cinnamonum verum) are two major types of cinnamon that are available in the US. â#oealthough both types of cinnamon are metabolized into sodium benzoate by mass

spectrometric analysis we have seen that Ceylon cinnamon is much more pure than Chinese cinnamon as the latter contains coumarin a hepatotoxic moleculeâ#said Pahan. â#oeunderstanding how the disease works is important to developing effective drugs that protect the brain

They found that tropical forests absorb almost two billion tonnes of carbon each year equivalent to one-fifth of the world's carbon emissions by storing it in their bark leaves and soil.

Generally a smooth surface was more attractive than rough bark. Wind direction appears to be one of the factors that determine where exactly the male perches to distribute his scent.

Bark beetles change Rocky mountain stream flows, affect water qualityon Earth Week--and in fact every week now--trees in mountains across the western United states are dying thanks to an infestation of bark beetles that reproduce in the trees'inner bark.

and is very difficult to locate because of their adept mimicry of bark moss and lichen.

As highly visual predators the bark mantis species appear to be active hunters that pursue prey as opposed to ambush hunters that wait for prey to come close.

Also like a similar bark mantis group from Australia (Ciulfina) this Neotropical group does not appear to exhibit cannibalism

which is an often misunderstood characteristic exhibited by some praying mantis species. The research brings to light a previously unknown diversity of bark mantises.

Break off a branch from the nearest pine tree peel away the bark and slowly pour lake water through the stick.
