WebJan 20, 2014 · In engineering and economics, trade-offs are familiar enough (e.g., money spent on rent is not available to buy food). In biology, a trade-off exists when one trait cannot increase without a decrease in another (or vice versa). Such a situation can be caused by a number of physical and biological mechanisms. One type of mechanism is described ...
WebGeometric growth is a situation where successive changes in a population differ by a constant ratio. So while exponential growth is a drastic amount of growth in a short amount of time and logistic is growth that practically stops at some point, geometric growth … Fitness (often denoted $${\displaystyle w}$$ or ω in population genetics models) is the quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype. Fitness can be … See more Fitness is often defined as a propensity or probability, rather than the actual number of offspring. For example, according to Maynard Smith, "Fitness is a property, not of an individual, but of a class of individuals—for … See more In order to avoid the complications of sex and recombination, the concept of fitness is restricted to an asexual population without genetic recombination.

Charles Darwin outlined the mechanisms of how species change, by natural selection and sexual selection. WebApr 8, 2024 · In ecology, the concept of niche emerged to explain the fitness variation between organisms and how that shapes their coexistence in space and time. For tumour ecology, fitness is associated with cell proliferation or expansion and persistence over time. Ecological niche has been defined following two main theories.
