✦ Synopsis

The ecology and electrophoretic properties of a damselfly, Argia vivida Hagen, inhabiting a geothermal gradient were studied. Monthly sampling of five sites revealed nymphal colonization along a 15-4o°C thermal gradient ; greatest densities occurred between 15-27'C . An electrophoretic analysis of proteins suggest that nymphs were adapted to a wide range of temperatures which was evidenced by differential activity of four enzyme systems (glucose-6-phosphate dehydrogenase, lactate dehydrogenase, leucine aminopeptidase, and tetrazolium oxidase) . Evidence suggests the nymphs acclimated to different temperatures by altering the structure of important isozymes and expressed certain genetic features characteristic of individuals naturally found at a given temperature .

The electrophoretic mobilities of double-stranded (ds) DNAs and ds RNAs of various lengths, L, were measured in gels of 0.4-1.8% (w/v) agarose at a voltage gradient of 1.0 V/cm. Differences in the electrophoresis of ds DNA and ds RNA are presented and discussed. A general expression is derived that
