Description:

Abstract:: Wetland and riparian habitats are vital to nutrient and energy transfer between aquatic and terrestrial systems, and are also major biodiversity foci within landscapes. Arthropods comprise the bulk of animal biodiversity and provide a host of essential ecosystem functions accentuated by their basal and intermediate positions in trophic webs. While “purely” aquatic and terrestrial arthropod faunas are often relatively well known, the same cannot generally be said of those arthropods existing at the aquatic-terrestrial interface. To this end, a series of pitfall traps was maintained during the snow-free seasons of 1995 and 1996 in riparian floristic communities along the lower 13 km of Big Beaver Creek.
As part of the Big Beaver Creek project, this study of the North Cascades National Park Service Complex riparian Coleoptera (beetles) deals with one of the largest and most ecologically diverse groups of arthropods to be found within the Park Complex. The majority of the arthropods collected during this study were beetles, results similar to those of other riparian arthropod surveys. The known trophic roles of these beetles range from detritivores to predators. A total of 360 species of beetles in 49 families were identified from the 18,766 individuals collected. Discounting those species known to be attracted to carrion, almost all individuals (90%) were representatives of only four beetle families: Anthicidae, Carabidae, Elateridae, and Staphylinidae. Although the vast majority of individuals and species were true riparian constituents, some species would normally be found only in habitats such as on flowers, under bark or within truly aquatic situations. Given the remoteness and essentially pristine condition of the Big Beaver Creek study sites, it was surprising to find a few individuals of five species representing taxa introduced into North America from Europe. In both years, the Alder Swamp habitat had the greatest species richness, while the Gravel Bar habitat had the most unique species composition.

Purpose:: To document occurrence, life history information, and information concerning taxonomy of species of Coleoptera.

Supplemental_Information:: This report represents one of a series of five technical reports on our efforts to document arthropod occurrence, abundance, and habitat associations in the Big Beaver Creek Research Natural Area of North Cascades National Park Complex (NOCA), located in northwestern Washington.
