... to disperse under adverse conditions ( Leys and Watts, 2008 ). Many aquatic insects and in particular small species are likely to benefit to some degree from cutaneous respiration ( Vlasblom, 1970 ). The ability of these subterranean dytiscids to rely solely on this mode of respiration and at relatively high...

... factors, e.g. bioenergetics costs. We caution against the use of short-term thermal ramping approaches to estimate critical thermal limits (CT max ) in aquatic insects because those temperatures are typically higher than those that occur in nature. * These authors contributed equally to this work...

...Karl K. Jones; Edward P. Snelling; Amy P. Watson; Roger S. Seymour ABSTRACT Many aquatic insects utilise air bubbles on the surface of their bodies to supply O 2 while they dive. The bubbles can simply store O 2 , as in the case of an ‘air store’, or they can act as a physical ‘gas gill...

...Roger S. Seymour; Karl K. Jones; Stefan K. Hetz ABSTRACT The river bug Aphelocheirus aestivalis is a 40 mg aquatic insect that, as an adult, relies totally on an incompressible physical gill to exchange respiratory gases with the water. The gill (called a ‘plastron’) consists of a stationary layer...

...Monica D. Poteat; Mauricio Díaz-Jaramillo; David B. Buchwalter SUMMARY Despite their ecological importance and prevalent use as ecological indicators, the trace element physiology of aquatic insects remains poorly studied. Understanding divalent metal transport processes at the water–insect...
