The Temperate Deciduous Forest: The Hydrologic Cycle

The Hydrologic Cycle

One major biogeochemical cycle of the Temperate Deciduous Forest is the hydrologic cycle. The hydrologic cycle-better known as the water cycle-of this biome begins with the evaporation of bodies of water (in this biome: the ocean and smaller bodies such as lakes, rivers, etc) into the atmosphere, as well as transpiration of plant life (such as trees) into the air. This water vapor then rises to form clouds with condensation. It then cools and condenses into rain or snow within these clouds, falling towards the surface as precipitation. The water flows into these bodies of water through runoff, then either percolates into the soil or evaporates into the atmosphere, beginning the process again.

The Temperate Deciduous Forest: K-Selected and R-Selected Species

Alyssa Nucci AP Biology-4 The Temperate Deciduous Forest: K-Selected and R-Selected Species K-selected species are species whose populations fluctuate at or near the carrying capacity of the environment. K-selected species have relatively stable populations and produce low numbers of offspring, therefore are density dependent. These species are characterized by long gestation periods, slow maturation, and long life spans. K-selected species tend to live in stable biological communities like forests. Examples of K-selected species include the American black bear, red fox, and white-tailed deer. R-selected species are species whose populations are defined by their biotic potential, meaning their maximum reproductive capacity. These species produce high numbers of offspring, require short gestation periods, mature quickly, and have short life spans. R-selected species ...

The Temperate Deciduous Forest: Keystone Species

Alyssa Nucci AP Biology-4 The Temperate Deciduous Forest: Keystone Species Keystone species are organisms within an ecosystem in which other species largely depend upon, furthermore upholding the sustainability of the ecosystem. In the Temperate Deciduous Forest biome, a keystone species is the white-tailed deer. This is because their feeding activity can affect many plants and animals in the surrounding environment. White-tailed deer thrive best in forests with biodiversity. In the spring and summer seasons, these deer eat grasses, wildflowers, mushrooms, and woody plant leaves. As fall begins, the deer gravitate towards acorns, fallen fruits, and crops. In winter, deer eat woody vegetation such as twigs, bark, and foliage. Deer are preyed upon by wolves, coyotes, bears, bobcats, and humans. As prey, their carcasses can sustain other organisms in their environment such as eagles, ravens, crows, etc. D...

The Temperate Deciduous Forest: Predatory/Prey Relationship

Alyssa Nucci AP Biology-4 The Temperate Deciduous Forest: Predator/Prey Relationship It is given that predators influence the population of their prey. However, it is shown here that conversely, prey affects the number of predators. As the number of prey drops, so does the number of predators, due to a now limited food supply. Here is an example of a common predator/prey relationship in the Temperate Deciduous Forest: Wolves and Rabbits. As the number of wolves decreases, in turn the number of rabbits begins to increase again, eventually increasing the number of wolves. This cycle can repeat indefinitely as long as the predator and prey populations remain. “Predator-Prey Interaction .” Predator-Prey Interaction , www2.nau.edu/lrm22/lessons/predator_prey/predator_prey.html.
