Abstract:: The North American species of the shore fly genus Notiphila Fallen were taxonomically revised. Over 13,000 specimens were examined from throughout the Nearctic Region and information relating to the biology of many species occurring in the West was gathered from both field and laboratory studies. Previously used characters were reevaluated;...

Abstract:: Monitoring wildlife habitats has become important to forest ecosystem management because it provides valuable information about the response of forests and their species to harvest practices, impacts from recreational use, conservation efforts, and natural and human-caused disturbances. Monitoring is a complex task that requires a variety of abiotic and biotic...

Abstract:: The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...
