Example text

This nitrogen conversion is made possible by the growth of microorganisms, such as specific types of bacteria, on rootlets of these trees. Certain trees, such as flowering dogwood and tulip poplar, concentrate large amounts of calcium, which was obtained from the soil, in their foliage; other trees, such as American beech and eastern hemlock, are low in calcium uptake. Calcium is a major nutrient affecting the acidity of forest soil. 5) in calcium-rich soils. Animals of the eastern deciduous forest also require nutrients for normal growth.

The eastern chipmunk also is territorial, but it is solitary, and only the mother cares for the young. Each sex, however, defends a territory centered around the individual's burrow system (Yahner 1978). The white-tailed deer, like virtually all deer species, is not territorial. There is evidence, however, that an adult female white-tail will defend a limited amount of area around her fawns, called a fawning ground, for a few weeks after their birth (Ozoga,Verme, and Bienz 1982). Defense of a fawning ground probably acts to better ensure adequate food resources for the adult female with young, particularly when deer densities are high.

Loamy soil is ideal for forest mammals that burrow, like the eastern chipmunk, which relies on extensive burrow systems for home and hibernation sites (Svendsen andYahner 1979). The humification layer is broken down to minerals, carbon dioxide, water, and humus. Below the O horizon are four additional horizons (A, E, B, and C), which except for the upper A horizon lack organic matter (Bockheim 1990). 5 millimeters) of pines and oaks, for instance, are in the upper 13 centimeters of the surface soil (Coile 1937; Kozlowski 1971).
