In environmental science, a population "overshoots" its local carrying capacity — the capacity of the biome to feed and sustain that population — when that population has not only begun to outstrip its food supply in excess of regeneration, but actually shot past that point, setting up a potentially catastrophic crash of that feeder population once its food populations have been consumed ...
Pollution may also cause extinction debt by reducing a species' birth rate or increasing its death rate so that its population slowly declines. [9] Extinction debts may also be caused by invasive species [10] or by climate change. Extinction debt may also occur due to the loss of mutualist species.
Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. [15] It is the study of how the population sizes of species living together in groups change over time and space, and was one of the first aspects of ecology to be studied and modelled mathematically.
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. [2]
The developments of modern healthcare and medicine, such as antibiotics, drastically reduce infant mortality rates and extend average life expectancy which, coupled with subsequent declines in fertility rates, reflects a transition to chronic and degenerative diseases as more important causes of death. The theory of epidemiological transition ...
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 ...
Disease ecology is a sub-discipline of ecology concerned with the mechanisms, patterns, and effects of host-pathogen interactions, particularly those of infectious diseases. [1] For example, it examines how parasites spread through and influence wildlife populations and communities.
Ecological death is the inability of an organism to function in an ecological context, leading to death. [1] This term can be used in many fields of biology to describe any species .
