Comparative studies of the population ecology and life history patterns of an alkaline salt lake insect : Ephydra (Hydropyrus) hians Say (Diptera:Ephydridae)

Creator:

Herbst, David B.

Abstract:

Seasonal abundance and life history traits were compared between populations of the brine fly Ephydra (Hydrokyrus) hians Say (Diptera:Ephydridae), from two western Great Basin alkaline salt lakes. Abert Lake, Oregon, has a relatively low salinity (20-30 g/1 total dissolved solids) and more co-inhabitant benthic species than the higher salinity Mono...
