Behavioral circadian rhythm
Any measurable or observable behavioral characteristic related to a daily biological activity cycle.
A major class of ecologically similar communities of plants, animals, and other organisms. Biomes are defined based on factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and other factors like climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation.
Body length (VT)

The degree of heat in the body of a living organism, temperature is measure of the average kinetic energy of the particles in a sample of matter, expressed in terms of units or degrees designated on a standard scale.
Single birth offspring quantity. The proportion or number of offspring produced from a single pregnancy (mammals) or ovulation (fish) or nesting (birds).

Gestation period duration
The length of time between when a fertilized egg implants in the wall of the uterus and the birth of offspring.
A category or description of the habitat in which the Event occurred.
The natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.
