Compensation law of mortality is a paradoxical empirical observation, and it represents a challenge for methods of survival analysis based on proportionality assumption (proportional hazard models). The compensation law of mortality also represents a great challenge for many theories of aging and mortality , which usually fail to explain this ...
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 ...
This demonstrated that the mortality rates from each specific cause were expected to decline as total mortality declined. The major causes accounting for the decline were all infectious and parasitic diseases. [12] McMichael et al. argue (2004) that the epidemiological transition has not taken place homogeneously in all countries.
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.
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.
The Theory of Island Biogeography is a 1967 book by the ecologist Robert MacArthur and the biologist Edward O. Wilson. [1] It is widely regarded as a seminal work in island biogeography and ecology. The Princeton University Press reprinted the book in 2001 as a part of the "Princeton Landmarks in Biology" series. [1]
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 .
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.
