Määritelmä: A multi-tissue plant structure (PO:0025496) that develops from a gynoecium (PO:0009062) and may have as parts one or more seeds (PO:0009010)
Määritelmä: The initial mortality rate (IMR) represents the mortality rate independently of the ageing process. Though there are different methods, the IMR is typically estimated from the mortality rate prior to its exponential increase with age, which can be obtained from the mortality curve (by looking at the baseline mortality prior to its exponential increase) or, for mice, by using t = 0.25 in the Gompertz equation.
Määritelmä: The mortality rate doubling time (MRDT) is considered to be a measure of the rate of ageing. It is estimated from the slope of the Gompertz curve by: MRDT = 0.693/G where G is the exponential (Gompertz) mortality rate coefficient.
Määritelmä: The duration of the development from fertilized, deposited or implanted egg to hatching/birth. Corresponds to egg incubation duration in oviparous animals and to gestation period duration in viviparous animals.
Määritelmä: Description of the relationships among individuals within a population of organisms, including reproductive relationships (mating system), relationships within each sex, adult – young interactions, helpers and cooperation (group living).
Määritelmä: where individuals of the same species (conspecifics), maintain spatial proximity with one another over time with mechanisms of social attraction
