Usually, the complex of external physical, chemical, and biotic factors that may affect a population, an organism, or the expression of an organism's genes; more generally, anything external to the object of interest (e.g., a gene, an organism, a population) that may influence its ...
12 Many biotic factors affect individuals in a population. An example of an organism being directly affected by a biotic factor is (1)(1) a squirrel cannot find a mate(2) a flood washes away a maple tree(3) a plant is in a dark room(4) a chipmunk finds a rock pile to use for ...
Factors That Influence the Biotic Potential of a Population As previously mentioned, biotic potential is determined by an organism's ability to produce offspring. However, there are a few factors that can influence an organism's reproductive capacity or potential. The following factors determine how ...
Another example is the population of zebras, antelope, or other animals, which are the biotic factors for lions that hunt and consume them for the latter’s survival. A disease-causing virus is also a biotic factor that can affect animal and human populations by causing disease, especially on...
Factors affecting the abundance and size of Pisaster ocharceus in the rocky intertidal zone of southern British Columbia This study investigates the abiotic and biotic factors that affect the abundance and distribution of the sea star Pisaster ocharceus in the intertidal zone... SH Keely - 《Bios...

Niche/distributional models characterize environmental/habitat suitability or species presence using predictor variables unaffected by (= unlinked to) the population of the focal species. Such variables (termed 'scenopoetic') typically have been considered to include only abiotic factors. In contrast, ...

Every species has to deal with limiting factors. These are aspects of the species' environment that affect how quickly it reproduces or how large the population can grow. For example, predators are a limiting factor for prey animals because predators reduce or limit the prey animal population....
in which effects can potentially be detected before they affect survival14,38. We found that the effects of individual and combined environmental factors varied greatly depending on the trait being investigated (Figs 2and3), and consequently the overall performance measure was highly variable. In bot...
