Glossary for Alauda
- animal habitation
- The dwelling of an animal or group of similar animals.
- Body length (VT)
- The distance from point to point along the longest axis of the body of an organism.
- 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).
- A plane angle unit which is equal to 1/360 of a full rotation or 1.7453310^[-2] rad.
- degrees Celsius
- 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.
- A category or description of the habitat in which the Event occurred.
- An upland moor or sandy area dominated by low shrubby vegetation including heather.
- Area of dry or relatively dry land surrounded by water or low wetland.
- 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.
- The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.
- Litters per year
- Number of litters per female per year
- The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.
- million years ago
- 1 megaannum in the past. Megaannum, Ma. is a unit of time equal to one million (10^6) years.
- Milliliters per liter. A volume per unit volume unit which is equal to one millionth of a liter of solute in one liter of solution.
- A mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island. Typically formed from volcanoes that rise abruptly and are usually found rising from a seafloor of 1,000 - 4,000 meters depth. Independent features that rise to at least 1,000 meters above the seafloor.
- Onset of fertility
- The age at which an organism develops the ability to produce live offspring.
- A dimensionless ratio unit which denotes numbers as fractions of 100.
- Practical Salinity Units. The conductivity ratio of a sea water sample to a standard KCl solution. Used to represent salinity.
- A plain without trees (apart from those near rivers and lakes); it is similar to a prairie, although a prairie is generally considered as being dominated by tall grasses, while short grasses are said to be normal in the steppe. It may be semi-desert, or covered with grass or shrubs or both, depending on the season and latitude.
- total life span
- The full period of time from birth to death of an organism.
- water dissolved O2 concentration
- Dissolved oxygen concentration in seawater at a location where this organism has been observed or collected.
- water nitrate concentration
- Dissolved nitrate concentration in seawater at a location where this organism has been observed or collected.
- water O2 saturation
- The percent oxygen saturation in seawater at a location where this organism has been observed or collected.
- water phosphate concentration
- Dissolved phosphate concentration in seawater at a location where this organism has been observed or collected.
- water salinity
- Dissolved salt concentration in seawater at a location where this organism has been observed or collected.
- water silicate concentration
- Dissolved silicate concentration in seawater at a location where this organism has been observed or collected.
- water temperature
- Temperature of the water at a location where this organism has been observed or collected.
- A physical quality inhering in a bearer that has mass near a gravitational body.
- A unit of molarity which is equal to one millionth of a molar or 10^[-6] mol/L
