Wood frog (Lithobates sylvaticus)
A very unique species is the wood frog. These frogs are well adapted to cold conditions by accepting the freezing of their blood and other tissues in their body and still can survive, but only if less than 65% of their body water does not freeze up. Generally being various shades of brown, the wood frog can reach lengths up to 7 centimeters, with females being larger than the males, with light or pale colored belly. Adults are generally variations of brown and normally prey on flies or beetles. Juveniles commonly feed on algae or plant materials and transform to a mature adult in approximately 45 days. The call of the male wood frog is generally seen as the signal that winter is now over and many wood frogs immerge from hibernation to start breeding.
Blue spotted salamander (Ambystoma laterale)
Within skin between a variation of blue and black, this salamander can grow to reach lengths between 8 and 14 centimetres, from which its tail contributes roughly 40%. It has white speckles throughout its back with blue-white spots occurring on its sides. They have 4 toes on each of the front legs and 5 on each of its hind legs which are relatively long. Males are females can be distinguished based on size, as males are slightly smaller than the females along with the males having longer and more flat tails. Females can lay up to 500 eggs per year and it only takes a month for the eggs to hatch. For shelter they commonly make use of rocks, logs or leaf clutter and they are generally found near water sources during the summer as it provides them with an appropriate breeding environment.

...er, which yellows the bases of the needles, which can result in the death of a tree if it is exposed to this disease for a long time. Insects prone to attack these trees include the jack pine budworm and the white pine weevil.
Bog bilberry (Vaccinium uliginosum)
This little shrub is deciduous and only grows to become less than a meter tall. With stems that are brown, this shrub produces white-pink flowers, normally 4 to 6 millimeters long, and has egg-shaped leaves, that are between 4 and 30 millimeters in length and 2 to 15 millimeters in width, that are green to blue in coloration and have a rubbery texture. The diagnostic characteristic of this shrub is its fruit. The bog bilberry produces a berry that is black-blue that is sweet and edible and varies between 5 and 8 millimeters in thickness. The bog bilberry generally prefers acidic soils to grow optimally.
Shortleaf Pine (Pinus echinata) and Pulp and Lumber Production. Introduction Shortleaf pine (Pinus echinata) is commercially one of the four most important conifers in the southeastern United States. In fact, shortleaf pine has the widest range of all southern pines, spreading from Florida to New Jersey and from North Carolina to Oklahoma. Sidney Investments, a firm based in Dallas, Texas, is considering the purchase of a 360-acre parcel of forested land located in the Quachita Mountains of eastern Oklahoma. This land has been under timber production through one rotation to this point.
What is the most important element of a good story? Although interesting characters, engaging plot development and didactic story lines certainly embellish the story, one could argue that the setting is the most crucial. Not only does the setting provide a baseline of necessary background information, it can also be used to enhance the story, just like the other elements listed. Edgar Allan Poe certainly takes advantage of this in “Hop Frog”, “The Cask of Amontillado”, and the “Masque of the Red Death”. In each of these stories, gruesome horrors occur, and because of the ingenious way Poe uses and manipulates the setting to his advantage, these stories’ horrors are amplified. In “Hop Frog” and “The Cask of Amontillado”, the main characters
The frog’s back is usually textured with coarse tubercles. Its fingers are thinly webbed while the hind foot is more developed. Large disks exist on the fingers and toes to assist with climbing and sticking to objects (Dickerson, 1969). The male and female Grey Tree Frogs are very similar. They are distinguished by the male having a dark underside of his throat. Also the females ears are smaller then the males (Dickerson, 1969).
“Be more concerned with you character than your reputation, because your character is what you really are, while your reputation is merely what others think you are.” These words of John Wooden are just a few out of many wise quotes millions of people, not just athletes, are inspired by today and likely will continue to be inspired by for a very long time. Basketball fans and experts consider John Wooden as one of, if not, the greatest coaches of all time. Much of his success is a result of his beliefs and coaching system. Knowing the background of Coach Wooden’s playing and coaching career plays a significant role in understanding how he practiced his beliefs with his teams and how his philosophy and success intertwined to set a precedent for the remainder of collegiate basketball.
To begin with, the first characteristic that describes Hop Frog is that he is unfortunate of being a fool. One way Hop Frog is unfortunate of being a fool is that he is bullied
Most owls are nocturnal birds that are found everywhere in the world. The fossils of the owls’ existence have dated back 54 million years ago. There are 205 different owl species. The owl species are divided into 2 different groups, one known as the barn owl, and the other as the true owls. True owls are more common than barn owls. The picture above shows a burrowing owl, which is a species of true owls. They have round faces where as barn owls have heart shaped faces. Most owls use their binocular vision to hunt prey. Owls have large eyes that set forward on their heads that allow them to have excellent depth perception. Their eyes have several large special cells called rods that are sensitive to low light. Their eyes are fixed in their
The external structure (fig.1) shows a hard exoskeleton, which is shed at intervals throughout their lives in order that they can grow longer. The exoskeleton consists of segments and the first section has a fusion of the thorax and the head4. The uropod at the rear of the Woodlouse is used for the uptake of water and this is achieved when they are pressed against moist surfaces5. Woodlice cannot retain water for long periods of time and because they have a large surface area to volume ratio they loose water quickly by diffusion6.

It also has vital parental care meaning they are independent at birth. The hedgehog reproduces by the male getting pregnant. The male seahorse is equipped with a pouch on the ventral, or front-facing, side of the tail. When mating, the female seahorse deposits up to 1,500 eggs in the male's pouch. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed but very
The female red Oophaga pumilios prefers to only mate with red males which leads to speciation. According to GrrlScientist, 4 researchers conducted an 18-month mark-recapture study on this. These researchers captured 677 wild Oophaga pumilios (312 males, 274 females, and 91 juveniles) (GrrlScientist, “Choosy Females Speed Speciation of Poison Dart Frogs.”). When the researchers analyzed the data, they found that 91% of the females mated with red males. With the yellow females, there was no clear pattern on how they mated leaving out that most of the frogs were red. That leaves the frogs that were yellow not being able to breed down. If this was to continue, then the frogs would separate and become different species of different
Really there wasn't much of a drive to find the first fossils discovered. When they were first found, that's all they were, found. As stated by Sues in “European Dinosaur Hunters” (1997) most of the first fossils discovered were usually fragments found in quarries. They just started showing up when people dug holes or built things. But once it was realized by the scientific community that these were the petrified remains of creatures that once lived, they became more and more valuable, and they actually became sought after. Paleontologists are always looking for new fossils of new animals to add to the list of discoveries. Like explorers in the dark depths of the jungles of South America,
Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth

Frogs live on every continent except Antarctica, but tropical regions have the largest amount. Like all amphibians, frogs spend half their lives near water because they must return to the water to lay their eggs. Frogs live underwater mostly when the are growing up to be an adult frog and when they are laying their eggs. When they hatch under water they are tadpoles and the breath with gills and swim using a tail. As they mature they loose their tail and they develop to be able to breathe air. During an extensive period of heat, a drought, frogs can enter a period of damancy similar to hibernation called starvation. Most of the frogs live in tropical and semitropical regions, most species of frogs breed in the spring or in early summer. Although the different species my vary in size and color, mostly all frogs have basic body structure. They have large hind legs, short front legs and flat head and body with no neck.
