Adaptive capacity confers resilience to perturbation, giving ecological and human social systems the ability to reconfigure themselves with minimum loss of function.In ecological systems, this resilience shows as net primary productivity and maintenance of biomass and biodiversity, and the stability of hydrological cycles.
Adaptation is an observable fact of life accepted by philosophers and natural historians from ancient times, independently of their views on evolution, but their explanations differed.
Word definitions of adaptability as a specialised term differ little from dictionary definitions. According to Andresen and Gronau [1] adaptability in the field of organizational management can in general be seen as an ability to change something or oneself to fit to occurring changes. In ecology, adaptability has been described as the ability ...
In behavioral ecology, adaptive behavior is any behavior that contributes directly or indirectly to an individual's reproductive success, and is thus subject to the forces of natural selection. [1] Examples include favoring kin in altruistic behaviors , sexual selection of the most fit mate, and defending a territory or harem from rivals.
In evolutionary ecology, an ecotype, [note 1] sometimes called ecospecies, describes a genetically distinct geographic variety, population, or race within a species, which is genotypically adapted to specific environmental conditions.
A stricter definition of local adaptation requires 'reciprocal home site advantage', where for a pair of populations each out performs the other in its home site. [ 5 ] [ 2 ] This definition requires that local adaptation result in a fitness trade-off, such that adapting to one environment comes at the cost of poorer performance in a different ...
Social-ecological systems are based on the concept that humans are a part of—not separate from—nature. [8] This concept, which holds that the delineation between social systems and natural systems is arbitrary and artificial, was first put forth by Berkes and Folke, [9] and its theory was further developed by Berkes et al. [10] More recent research into social-ecological system theory has ...
Ecology is as much a biological science as it is a human science. [5] Human ecology is an interdisciplinary investigation into the ecology of our species. "Human ecology may be defined: (1) from a bioecological standpoint as the study of man as the ecological dominant in plant and animal communities and systems; (2) from a bioecological ...
