The presence, diet and relative abundance of otters (Carnivora: Mustelidae) in Northern Namibia
… and Okavango rivers, their diet as well as their relative abundance. Community sightings of otters were utilized, along with on sight observations (for example, sightings and signs) while collecting data in the field to determine the presence of otter species. Sightings of the African clawless and …

An assessment of a herpetofaunal community in Hamilton, County, Tennessee: baseline ecology, species richness, and relative abundance
… a 32-month study investigating species richness, abundance, sex ratios, and body sizes of amphibians and reptiles in a Hamilton County, Tennessee, wetland. Utilizing drift fencing in conjunction with pitfall arrays, a total of 14 reptile species and 16 amphibian species was recorded. Evenness was …

Population/Biomass Estimates and Relative Abundance Indices of Adult Common Carp in Arrowwood and Sand Lake National Wildlife Refuges
Fish catch rates in passive gear, such as gill nets, are commonly used by biologists to index fish population density. The purpose of this project was to assess the potential relationship between common carp (Cyprinus carpio) biomass and catch-per-unit-effort (CPUE) in gill nets. Adult common carp …
