Glossary for Zalophus californianus
- Animal population density
- Number of animals in a population relative to space.
- An area of water bordered by land on three sides.
- 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.
