Biogeography

habitat patches

Biology; Biogeography

Areas distinguished from their surroundings by environmental discontinuities. Patches are organism-defined (i.e., the edges or discontinuities have biological significance to an organism).

ultimate factors

Biology; Biogeography

Aspects of the environment that are directly important to the well-being of an organism (for example, food). Ultimate factors are concerned with fitness.

proximate factors

Biology; Biogeography

Aspects of the environment that organisms use as cues for behavior; for example, daylength.

numerical response

Biology; Biogeography

Change in the population size of a predatory species as a result of a change in the density of its prey.

Changes in population caused by the relative distributions of habitat patches containing nonsubstitutable resources in a landscape. Example: increased populations in a portion of a landscape where ...

landscape supplementation

Biology; Biogeography

Changes in populations caused by the distribution of habitat patches containing substitutable resources in a landscape. Example: increased population in a small patch found in a portion of the ...

climate change

Biology; Biogeography

Changes in the global climate system in response to physical feedbacks, chemical feedbacks, and changes in terrestrial and aquatic systems caused by humans and nature.
