Effects of salinity on the life history and fitness of ,: variability within and between populationsses within and between populations was examined by comparing 11 clones from a brackish lake and 10 clones from a freshwater pond. Experimental clones were hatched from ephippia collected from the sediment and thus represent random samples of the clone banks of each population..Most clones with a hig

Phylogeny and adaptive radiation within the Anomopoda: a preliminary explorational anomopod, which probably lived in Palaeozoic times. This task is facilitated by the availability of detailed information on extant forms, which includes functional as well as purely morphological considerations and enables us to understand the means whereby complex mechanisms were transformed dur

The evolution of groundwater Cladoceranto groundwater; some chydorids are more common in groundwaters than in surface waters; at least three groups within ., finally, have evolved exclusive groundwater species. The latter show few obvious adaptations to the subterranean habitat, except loss of an eye or total blindness. Some, however, h

Altitudinal distribution of tropical planktonic Cladocerave altitudinal ranges of 2000 m within a latitudinal band of 10 °. It is possible to distinguish tropical species which do not extend up to high altitudes, particularly at higher latitudes. At the lowest latitudes, some species are found only at high altitudes, but occur at progressively lower altit

The conservation ecology of the Podonidae from the Caspian and Aral seasecies of Podonidae were found, all of which were fairly euryhaline, except .. Further, all of them were thermophilic, except ., and .. Sexual reproduction of the Podonidae in these two salt lakes appears to be insignificant. The possibility exists that parthenogenetic females of some species can liv
