Disturbance forces can have profound immediate effects on ecosystems and can, accordingly, greatly alter the natural community’s population size or species richness. [2] Because of these and the impacts on populations, disturbance determines the future shifts in dominance, various species successively becoming dominant as their life history ...
Acute toxicity describes the adverse effects of a substance that result either from a single exposure [1] or from multiple exposures in a short period of time (usually less than 24 hours). [2] To be described as acute toxicity, the adverse effects should occur within 14 days of the administration of the substance. [2]
Proximate causation explains biological function in terms of immediate physiological or environmental factors. Example: a female animal chooses to mate with a particular male during a mate choice trial. A possible proximate explanation states that one male produced a more intense signal, leading to elevated hormone levels in the female ...
The immediate effects of stress hormones are beneficial in a particular short-term situation. The system is arguably a protective defense against threats [5] and usually does not pose a health risk. [7] However, the problem arises when there is a persistent threat.
