Density-dependent: Affect a population more or less as the population is bigger. Examples: [1] A bigger population may be more vulnerable to diseases and parasites. A bigger population may have more intraspecific competition, while a smaller population may have more interspecific competition.
The rate at which a population increases in size if there are no density-dependent forces regulating the population is known as the intrinsic rate of increase. It is d N d t = r N {\displaystyle {\mathrm {d} N \over \mathrm {d} t}=rN} where the derivative d N / d t {\displaystyle dN/dt} is the rate of increase of the population, N is the ...
Density-dependent mortality can be overcompensating, undercompensating or exactly compensating. [citation needed] There also exists density-independent inhibition, where other factors such as weather or environmental conditions and disturbances may affect a population's carrying capacity. [citation needed]
Population control may involve culling, translocation, or manipulation of the reproductive capability. The growth of a population may be limited by environmental factors such as food supply or predation. The main biotic factors that affect population growth include: Food – both the quantity and the quality of food are important. The ...
Based on factors of dispersal, disturbance, resources limiting climate, and other species distribution, predictions of species distribution can create a bio-climate range, or bio-climate envelope. The envelope can range from a local to a global scale or from a density independence to dependence.
The tick population is affected by weather and climate. Many factors determine tick population densities as well as diseased population densities of ticks so that no single factor can determine likelihood of exposure to tick-borne disease. [1] Overall climate [2] and primary host population [3] determine the
Ecologists have been unable to successfully explain regular population cycles for many decades; delayed density dependence may hold the answer. [2] Here populations are allowed to increase above their normal capacity because there is a time lag until negative feedback mechanisms bring the population back down.
Future population shifts that affect population density, as well as changes in the behavior of mosquitos, can affect transmission rates and are limiting factors in determining the future risk of malaria outbreaks, which also affect planning for correct outbreak response preparation. [74]
