The Osmotic and Ionic Regulation of Asellus Aquaticus (l.) By
The isopod, Asellus, has been reported from a wide range of conditions in fresh and brackish water. One species, A. aquaticus, has a natural salinity range from fresh water (0-15 m-equiv./l. Na; Moon, 1957) to the Baltic (103 mM./l. NaCl; Valikangas, 1933). Thienemann (1913) has also found it occurring in Westphalian brine pools at a concentration of 25-3 % salt (equivalent to 434 mM./l. NaCl)....
متن کاملCarotenoids and carotenoproteins in Asellus aquaticus L. (Crustacea: Isopoda).
Column (CC), thin-layer (TLC), high-performance liquid (HPLC) and ion-exchange chromatography (IEC), were used to investigate corotenoid and carotenoprotein complexes in Asellus aquaticus specimens from the Narew river. The following carotenoids were found: alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein, zeaxanthin, diadinoxanthin, mutatoxanthin, crustaxanthin, echinenone, hydroxyech...
متن کاملThe influence of fresh water pollutants and interaction with Asellus aquaticus (L.) on the feeding activity of Gammarus pulex (L.).
The feeding response of juvenile amphipod Gammarus pulex (L.) was investigated following exposure to freshwater pollutants. The method employed is nondestructive, provides a rapid indication of the status of groups of individuals, and is based on a time-response analysis of the consumption of the eggs of Artemia salina and the determination of median feeding times or FT50s. The feeding activity...

متن کاملA Transcriptomic Analysis of Cave, Surface, and Hybrid Isopod Crustaceans of the Species Asellus aquaticus
Cave animals, compared to surface-dwelling relatives, tend to have reduced eyes and pigment, longer appendages, and enhanced mechanosensory structures. Pressing questions include how certain cave-related traits are gained and lost, and if they originate through the same or different genetic programs in independent lineages. An excellent system for exploring these questions is the isopod, Asellu...
