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.
Species diversity is a combination of richness and evenness; it is species richness weighted by species evenness, and there are formulae that permit the diversity of a community to be expressed in a single number.he simplest measure of a diversity is to count the number of species. This is known as species richness. Each species, however, is not likely to have the same number of individuals in that community. One species might be represented by 1000 individuals, and another by 200, and a third by a single individual.
