fecundity

Examples of fecundity in the following topics:

• Density-Dependent and Density-Independent Population Regulation

  • The data shows that denser populations of the parasite exhibit lower fecundity: they contained fewer eggs .
  • The actual cause of the density-dependence of fecundity in this organism is still unclear and awaiting further investigation.
  • In this population of roundworms, fecundity (number of eggs) decreases with population density.

• Life History Patterns and Energy Budgets

  • Fecundity is the potential reproductive capacity of an individual within a population.
  • In animals, fecundity is inversely related to the amount of parental care given to an individual offspring.
  • Plants with low fecundity produce few energy-rich seeds (such as coconuts and chestnuts) that have a good chance to germinate into a new organism.
  • Plants with high fecundity usually have many small, energy-poor seeds (as do orchids) that have a relatively-poor chance of surviving.
  • Some life history traits, such as fecundity, timing of reproduction, and parental care, can be grouped together into general strategies that are used by multiple species.

• Natural Selection and Adaptive Evolution

  • An individual may carry a very beneficial genotype with a resulting phenotype that, for example, increases the ability to reproduce (fecundity), but if that same individual also carries an allele that results in a fatal childhood disease, that fecundity phenotype will not be passed on to the next generation because the individual will not live to reach reproductive age.

• Polyketide Antibiotics

  • Unlike primary metabolites, the absence of secondary metabolites does not result in immediate death, but rather in long-term impairment of the organism's survivability, fecundity, or aesthetics, or perhaps in no significant change at all.

• Data and Methods

  • Two of the most important indicators are birth and death rates, which are also referred to as fertility (see also fecundity) and mortality.
  • Fecundity is the potential reproductive capacity of a female.
  • Some of the more common demographic measures used in relation to fertility and/or fecundity include:

• Fertility

  • In demography, fertility refers to the actual production of offspring, rather than the physical capability to produce, which is called fecundity.
