Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard (Crangonyctidae) Living In Different Habitats Ii. Population Distribution, Gary W. Dickson Jan 1982

Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard (Crangonyctidae) Living In Different Habitats Ii. Population Distribution, Gary W. Dickson

International Journal of Speleology

Population densities and factors affecting the distribution of the troglobitic (i.e., obligatory cavernicole) amphipod Crangonyx antennatus were examined in two distinct aquatic habitats. Observations were made seasonally for one year in six Lee Co., Virginia (U.S.A.) caves, three with mud-bottom pools and three with gravel-bottom streams. Pool habitats were found to contain greater C. antennatus densities than stream habitats, while the highest seasonal densities were recorded in August. Availability of food is considered to be the major factor allowing these increased population densities. The population distribution of C. antennatus was not found to be related to current velocity, water depth, …
