If your cat or dog has diarrhea accompanied by fever, vomiting, blood in the stool, or lethargy, consult your veterinarian immediately, as these are serious symptoms. In these cases, hospitalization, antibiotics, and IV fluids might be necessary to treat your pet.
Biological diversity, or biodiversity, is the variety of life either in a particular place or on the entire Earth, including its ecosystems, species, populations, and genes. Conservation thus seeks to protect lifeâs variety at all levels of biological organization.
For example, species richness is the number of different species present. However, diversity depends not only on richness, but also on evenness. Evenness compares the similarity of the population size of each of the species present.
