Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard (Crangonyctidae) Living In Different Habitats, Iii: Population Dynamics And Stability, Gary W. Dickson, John R. Holsinger Jan 1981

Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard (Crangonyctidae) Living In Different Habitats, Iii: Population Dynamics And Stability, Gary W. Dickson, John R. Holsinger

International Journal of Speleology

Populations of the troglobitic amphipod Crangonyx antennatus from caves in Lee Co., Virginia (U.S.A.) were investigated on both a short and long term basis. The dynamics of populations living in two distinct aquatic cave habitats (mud-bottom pools and gravel-bottom streams) were compared seasonably for one year. Sex ratios indicated a larger number of females in both pool and stream habitats. The majority of males in both habitats were found to be sexually mature throughout the year investigated. Seasonal fluctuations in female maturity were observed in both habitats, with larger numbers collected in June and August. In addition, a larger number …


Investigation Of The Mutual Influence Between A Polluted River And Its Hyporheic, Milan Meŝtrov, Romana Lattinger-Penko Jan 1981

Investigation Of The Mutual Influence Between A Polluted River And Its Hyporheic, Milan Meŝtrov, Romana Lattinger-Penko

International Journal of Speleology

This paper describes investigations of fundamental biological and pratical importance. Interstitial subterranean water (hyporheic) which is near a polluted river in a plain is the subject of the study. The water is becoming increasingly important as a source of drinking water. The relation of the hyporheic water to the physical, chemical, bacteriological and faunistic characteristics of the river is discussed.
