What type of animals are found in Warm Temperate East in North America ? Pls write the names only
Answers
Answer:
Insects, spiders, slugs, frogs, turtles and salamanders are common. In North America, birds like broad-winged hawks, cardinals, snowy owls, and pileated woodpeckers are found in this biome. Mammals in North American temperate deciduous forests include white-tailed deer, raccoons, opossums, porcupines and red foxes.

Origin
Temperate forests originated during the period of cooling of world climate that began at the start of the Cenozoic Era (65.5 million years ago). As global climates cooled, climatic gradients steepened with increasing latitude, and areas with a hot, wet climate became restricted to equatorial regions. At temperate latitudes, climates became progressively cooler, drier, and more seasonal. Many plant lineages that were unable to adapt to new conditions became extinct, but others evolved in response to the climatic changes, eventually dominating the new temperate forests. In areas that differed least from the previously tropical environments—where temperate evergreen forests now grow—the greatest numbers of plant and animal species survived in forms most similar to those of their tropical ancestors. Where conditions remained relatively moist but temperatures dropped in winter, deciduous trees evolved from evergreen rainforest ancestors. In areas that became much more dry—though not to the extent that tree development was inhibited and only scrubland or desert environments were favoured—sclerophyllous trees evolved.
During the rapid climatic fluctuations of the past two million years in which conditions alternated between dry, cold glacial states—the ice ages of some northern temperate regions—and warmer, moister interglacial intervals, tree species of temperate forests had to migrate repeatedly to remain within climates suitable for their survival. Such migration was carried out by seed dispersal, and trees that were able to disperse their seeds the farthest had an advantage. In the North American and European regions where ice-sheet development during glacial intervals was most extensive, the distances that had to be traversed were greatest, and many species simply died out. Extinctions occurred not only where migration distances were great but also where mountains or seas provided barriers to dispersal, as in southern Europe. Thus, many trees that were formerly part of the European temperate forests have become extinct in the floristically impoverished forest regions of western Europe and are restricted to small refuge areas such as the Balkans and the Caucasus. For example, buckeye (Aesculus) and sweet gum (Liquidambar) are two trees that no longer occur naturally in most parts of Europe, having disappeared during the climatic turmoil of the past two million years.

Human activities have had pronounced effects on the nature and extent of modern temperate forests. As long ago as 8,000 years, most sclerophyllous forests of the Mediterranean region had been cut over for timber or cleared to make space for agricultural pursuits. By 4,000 years ago in China the same process led to the removal of most broad-leaved and deciduous forests. In Europe of 500 years ago the original deciduous forests had disappeared, although they are remembered in nursery tales and other folklore as the deep, wild woods in which children and princesses became lost and in which dwarfs and wild animals lived.
The deciduous forests of North America had been cleared almost completely by the end of the 19th century. Australia and New Zealand experienced similar deforestation about the same time, although the earlier activities of pre-European peoples had had substantial impacts. The character of the Australian sclerophyllous forests changed in response to more than 38,000 years of burning by the Aboriginal people, and the range of these forests was expanded at the expense of broad-leaved forests.
