, derived from the word fecund
, generally refers to the ability to reproduce
. In biology
, fecundity is the potential reproductive capacity of an organism
, measured by the number of gametes
(eggs), seed set or asexual propagules. Fecundity is under both genetic
and environmental control, and is the major measure of fitness
is another term for fertilisation
refers to an organism's ability to store another organism's sperm (after copulation
) and fertilize its own eggs from that store after a period of time, essentially making it appear as though fertilization occurred without sperm (i.e. parthenogenesis
Fecundity is important and well studied in the field of population ecology. Fecundity can increase or decrease in a population according to current conditions and certain regulating factors. For instance, in times of hardship for a population such as a lack of food, juvenile and eventually adult fecundity has been shown to decrease.
Fecundity has also been shown to increase in ungulates with relation to warmer weather.
In the philosophy of science, fecundity refers to the ability of a scientific theory to open new lines of theoretical inquiry.
