Biological diversity in the United States is summarized in three categories: genetic diversity, species diversity, and community/ecosystem diversity. Major changes have occurred in the distribution abundance of native diversity, in the United States, in ...

A low level of genetic variation in mammalian populations where the census population size is relatively large has been attributed to various factors, such as a naturally small effective population size, historical bottlenecks and social behaviour. The killer whale (Orcinus orca) is an abundant, highly social species with reduced ...

factors that contribute to the abundance of Microcystis genotypes and microcystin production. In addition, in a laboratory-based study we examined the effect of nutrients on transcriptional activity of the microcystin is the dominant microcystin producer in the lake, other microcystin-producing cyanobacteria were also found
Inbreeding and a consequent loss of genetic diversity threaten small, isolated populations. One mechanism by which genetically impoverished populations may become extinct is through decreased immunocompetence and higher susceptibility to parasites. Here, we investigate the relationship between immunity and inbreeding in bumblebees, ...
