Zoogeographic Affinities of Southwestern USA Plecoptera

Show Summary Details


This chapter examines the zoogeographic affinities of 75 Plecoptera species in New Mexico and Arizona. The findings indicate that in four major physiographic subdivisions of the study area, stonefly species arrange themselves in ways that reveal dispersal corridors, dispersal barriers, and refugia which operated during late Pleistocene pluvial and post-pluvial Holocene environments. The results also suggest that the southwestern Plecoptera fauna are distinct in their species composition, taxonomic representation, and level of endemism.
