WebWe used a comparative data set of 941 host‐parasite combinations, representing 101 anthropoid primate species and 231 parasite taxa, to test the relative importance of four sets of variables that have been proposed as determinants of parasite community diversity in primates: host body mass and life history, social contact and population ... WebAbstract. The most common definitions of biological diversity focus on state variables, such as genes, species, and communities, but processes, such as gene flow, survivorship, competition, and energy flow, ultimately determine the nature of these state variables and are critical to the survival of biological diversity itself (Noss 1990). sok battery 200ah 12v lifepo4 specs
