What does fecundity mean in biology?
Fecundity is the physiological maximum potential reproductive output of an individual (usually female) over its lifetime and represents one of the major cornerstones of theoretical and applied population biology. Fertility, a related concept, is defined as the current (actual) reproductive performance of an individual.
What is fecundity and examples?
For example fecundity is the potential to for a female to become pregnant and carry that pregnancy to a live birth in demography, while in clinical medicine it refers to actual production of live offspring.
What does fecundity mean in environmental science?
Fecundity is a measure of the reproductive potential of a species through the number of vitellogenic oocytes present in the ovaries before the breeding season (Bagenal and Braum, 1978).
What is the fecundity of humans?
Recognizing that there are many operational definitions of human fecundity, from a population research perspective, fecundity is defined as the biologic capacity to reproduce irrespective of pregnancy intentions, while fertility is demonstrated fecundity as measured by live births and sometimes stillbirths.
What is the difference between fecundity and prolificacy?
As nouns the difference between fecundity and prolificacy is that fecundity is ability to produce offspring while prolificacy is great fertility.
What is the difference between fecundity and fertility?
Fertility is the number of children born to a woman, while fecundity is her physiological potential to bear children. Fertility is often used as measure of fitness, and fecundity is related to reproductive value.
What is the period of fecundity?
2.4 Fecundability The monthly probability of conception, fecundability, is at most 0.15–0.25 among newlyweds and declines with increasing age and duration of marriage. It is this low because fertilization can occur only during about two days around the time of ovulation in the middle of the menstrual cycle.
What is fecundity describe fecundity as the base to fertility?
Literally, “fecundity” means the ability to produce live offspring, and “fertility” means the actual production of live offspring. So fecundity refers to the potential production, and fertility to actual production, of live offspring.
How do you determine fecundity?
The age-specific fecundity (mx) is calculated as the average number of offspring per female in age-class x. The sum of this column tracks the reproductive output of a hypothetical female that lives to the maximum observed age.
How do you measure fecundity?
In viviparous organisms, like placental mammals, fecundity is usually measured as the number of litters per year while in humans approaches to measuring fecundity include the assessment of time to pregnancy and day-specific probabilities of conception (daily fecundities) indexed to a day of ovulation.
What is the difference between fecundity and natality?
As nouns the difference between fecundity and natality is that fecundity is ability to produce offspring while natality is (demography) the ratio of live births in an area to the population of that area; expressed per 1000 population per year.
What does fecund mean in literature?
fecund \FEK-und\ adjective. 1 : fruitful in offspring or vegetation : prolific. 2 : intellectually productive or inventive to a marked degree. Examples: As an artist, she gets most of her inspiration from nature; her daily walks in the woods are a fecund source of ideas.
What is fecundity in biology?
In simpler terms, fecundity is the quantification of the number of individuals added to the population. In biology, fecundity is a measure of fertility. It may also pertain to the ability to produce offspring or to cause growth. In demography, it may be measured by counting the gametes, seed set, or asexual propagules.
Fecundity is the physiological maximum potential reproductive output of an individual (usually female) over its lifetime and represents one of the major cornerstones of theoretical and applied population biology. Fertility, a related concept, is defined as the current (actual) reproductive performance of an individual.
What is population fecundity and why is it important?
An estimate of population fecundity improves the ability to translate research in reproductive physiology into foreseen effects on fertility. Thus, fecundity is a very important parameter to study in ecology and animal biology. In ecology, fecundity is also an indication of the amount of energy that is spent on raising offspring.
What is fecundity rate?
Fecundity rate or reproductive rate quantifies the number of offspring an organism produces over time.
