A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
Debates over the validity of the IDH are ongoing within the discipline of tropical ecology as the theory is tested in various ecological communities. Other evidence exists for [15] [16] and against [17] [18] the hypothesis. The intermediate disturbance hypothesis has been supported by several studies involving marine habitats such as coral ...
The bioecological model of development is the mature and final revision of Urie Bronfenbrenner's ecological system theory.The primary focus of ecological systems theory is on the systemic examination of contextual variability in development processes.
Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment, such as birth and death rates, and by immigration and emigration.
Social ecological models are thus applicable to the processes and conditions that govern the lifelong course of human development in the actual environment in which human beings live. [8] Urie Bronfenbrenner's Ecological Framework for Human Development is considered to be the most recognized and utilized social ecological model (as applied to ...
Pediatric environmental health is based on the recognition that children are not “little adults.” Infants and children have unique patterns of exposure and vulnerabilities. Environmental risks of infants and children are qualitatively and quantitatively different from those of adults. Pediatric environmental health is highly interdisciplinary.
Spatial ecology studies the ultimate distributional or spatial unit occupied by a species.In a particular habitat shared by several species, each of the species is usually confined to its own microhabitat or spatial niche because two species in the same general territory cannot usually occupy the same ecological niche for any significant length of time.
Also Gause's law. A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...
