Glossary for Macropus (Osphranter) Gould, 1842
- age at first birth
- Age at which females give birth to their first litter, or their young attach to teats or hatch out
- body mass
- The amount of matter in the body of an organism.
- clutch/brood/litter size
- Single birth offspring quantity. The proportion or number of offspring produced from a single pregnancy (mammals) or ovulation (fish) or nesting (birds).
- The original description of the elevation (altitude, usually above sea level) of the Location.
- This taxon is still in existence, as opposed to extinct.
- extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- first appearance (older bound)
- The older bound for the first appearance of this taxon in the fossil record, in Ma.
- first appearance (younger bound)
- The younger bound for the first appearance of this taxon in the fossil record, in Ma.
- gestation period duration
- The length of time between when a fertilized egg implants in the wall of the uterus and the birth of offspring.
- inter-birth interval
- The length of time between successive births of a female.
- last appearance (older bound)
- The older bound for the last appearance of this taxon in the fossil record, in Ma.
- last appearance (younger bound)
- The younger bound for the last appearance of this taxon in the fossil record, in Ma.
- litters per year
- Number of litters per female per year
- million years ago
- 1 megaannum in the past. Megaannum, Ma. is a unit of time equal to one million (10^6) years.
- onset of fertility
- The age at which an organism develops the ability to produce live offspring.
- social group size
- Number of individuals in a group that spends the majority of their time in a 24 hour cycle together where there is some indication that these individuals form a social cohesive unit.
- total life span
- The full period of time from birth to death of an organism.
- weaning age
- Age when primary nutritional dependency on the mother ends and independent foraging begins to make a major contribution to the offspring’s energy requirements.
- A physical quality inhering in a bearer that has mass near a gravitational body.
For some attributes EOL determines the span of values available for a taxon across all sources.
