Genetic diversity is the variation in DNA sequence that is heritable from generation to generation and is manifested as variation in organismal form and function. Its loss r ...

temperature, desiccation, and species performance trends
... Despite the existing knowledge on intertidal elevational trends in temperature and desiccation, direct measurements in combination with measurements on species performance are rare. This is especially true for subpolar (cold-temperate) shores, which are best known for their harsh winter conditions [ ...

Patterns and Consequences of Interspecific Competition
