Tree frog

A tree frog is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state. Several lineages of frogs among the Neobatrachia have given rise to tree frogs, although they are not closely related to each other.

Many millions of years of convergent evolution have resulted in almost identical morphology and ecologies. They are so similar as regards their ecological niche that in one biome where one group of tree frogs occurs, the other is almost always absent. The last common ancestor of some such tree frog groups lived long before the extinction of the dinosaurs.

Description

As the name implies, these frogs are typically found in trees or other high-growing vegetation. They do not normally descend to the ground, except to mate and spawn, though some build foam nests on leaves and rarely leave the trees at all as adults.

Many tree frogs can change their color for better camouflage. For instance, the grey tree frog (Hyla versicolor) can change its color from green to grey to yellow .

Frog

Frogs are a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (Ancient Greek an-, without + oura, tail). The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is found in tropical rainforests. There are approximately 4,800 recorded species, accounting for over 85% of extant amphibian species. They are also one of the five most diverse vertebrate orders.

The body plan of an adult frog is generally characterized by a stout body, protruding eyes, cleft tongue, limbs folded underneath, and the absence of a tail in adults. Besides living in fresh water and on dry land, the adults of some species are adapted for living underground or in trees. The skin of the frog is glandular, with secretions ranging from distasteful to toxic. Warty species of frog tend to be called toads but the distinction between frogs and toads is based on informal naming conventions concentrating on the warts rather than taxonomy or evolutionary history; some toads are more closely related to frogs than to other toads. Frogs' skins vary in colour from well-camouflaged dappled brown, grey and green to vivid patterns of bright red or yellow and black to advertise toxicity and warn off predators.

Tree

In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a woody trunk and branches as a way to tower above other plants to compete for sunlight. In looser senses, the taller palms, the tree ferns, bananas and bamboos are also trees. Trees tend to be long-lived, some reaching several thousand years old. The tallest known tree, a coast redwood named Hyperion, stands 115.6 m (379 ft) high. Trees have been in existence for 370 million years. It is estimated that there are just over 3 trillion mature trees in the world.

A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves as a protective barrier. Below the ground, the roots branch and spread out widely; they serve to anchor the tree and extract moisture and nutrients from the soil. Above ground, the branches divide into smaller branches and shoots. The shoots typically bear leaves, which capture light energy and convert it into sugars by photosynthesis, providing the food for the tree's growth and development. Flowers and fruit may also be present, but some trees, such as conifers, instead have pollen cones and seed cones; others, such as tree ferns, produce spores instead.

Coyote

The coyote (US /kaɪˈoʊtiː/ or /ˈkaɪ.oʊt/, UK /kɔɪˈjoʊteɪ/, or /kɔɪˈjoʊt/;Canis latrans) is a canid native to North America. It is a smaller, more basal animal than its close relative, the gray wolf, being roughly the North American equivalent to the Old World golden jackal, though it is larger and more predatory in nature. It is listed as "least concern" by the IUCN, on account of its wide distribution and abundance throughout North America, even southwards through Mexico and Central America. It is a highly versatile species, whose range has expanded amidst human environmental modification. This expansion is ongoing, and it may one day reach South America, as shown by the animal's presence beyond the Panama Canal in 2013.As of 2005, 19 subspecies are recognized.

The ancestors of the coyote diverged from those of the gray wolf, 1–2 million years ago, with the modern species arising in North America during the Middle Pleistocene. It is highly flexible in social organization, living either in nuclear families or in loosely knit packs of unrelated individuals. It has a varied diet consisting primarily of animal matter, including ungulates, lagomorphs, rodents, birds, reptiles, amphibians, fish, and invertebrates, though it may also eat fruit and vegetable matter on occasion. It is a very vocal animal, whose most iconic sound consists of a howl emitted by solitary individuals.Humans aside, cougars and gray wolves are the coyote's only serious enemies. Nevertheless, coyotes have on occasion mated with the latter species, producing hybrids colloquially called "coywolves".
