Founded in 1953, the "North American Benthological Society (NABS) is an international scientific organization whose purpose is to promote better understanding of the biotic communities of lake and stream bottoms and their role in aquatic ecosystems, by providing media and disseminating new investigation results, new interpretations, and other benthological information to aquatic biologists and to the scientific community at large." Notably, NABS hosts a Classified Ads and Announcements section with listings for a variety of jobs; postdoctoral and graduate student positions; conferences and meetings; publications; and more. Academic institutions, nonprofit organizations, and NABS members are all invited to post suitable advertisements free of charge. The NABS website also offers information about the upcoming annual meeting in New Orleans, NABS publications, opportunities for graduate student involvement, and the Freshwater Algae and Macroinvertebrate Slide Library.
