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 کاملGenetic basis of eye and pigment loss in the cave crustacean, Asellus aquaticus.
Understanding the process of evolution is one of the great challenges in biology. Cave animals are one group with immense potential to address the mechanisms of evolutionary change. Amazingly, similar morphological alterations, such as enhancement of sensory systems and the loss of eyes and pigmentation, have evolved multiple times in a diverse assemblage of cave animals. Our goal is to develop...
متن کاملReduced survival associated with precopulatory mate guarding in male Asellus aquaticus (Isopoda)
Precopulatory mate-guarding in aquatic crustaceans is known to have immediate costs for the guarding male. The extent to which guarding behavior may reduce future reproductive opportunities, however, is less established. We examined the survival and antennae length, suggested to be important in detecting receptive females, in male freshwater isopods (Asellus aquaticus) collected paired or unpai...
