Carabids and other epigeal arthropods make important contributions to biodiversity, food webs biocontrol of invertebrate pests weeds. Pitfall trapping is widely used for sampling carabid populations, but this technique yields biased estimates abundance ('activity-density') because individual activity - which affected by climatic factors affects the rate catch. To date, impact temperature on pitfall catches, while suspected be large, has not been quantified, no method available account it....

The effects of tillage regimen (conventional [CT] and no-tillage [NT]) on the activity density diversity carabid beetles (Coleoptera: Carabidae) was studied by pitfall trapping within a rain-fed cropping system in northwestern Idaho, 2000–2002. rotation consisted spring cereal (barley, Hordeum vulgare L., 2000 2001; wheat, Triticum aestivum 2002), dry pea (Pisum sativum L.) 2000–2002, wheat (T. aestivum), 2001, winter 2002. A total 14,480 comprised 30 species captured, with five numerically...

Bumble bees, Bombus Latreille (Hymenoptera: Apidae:), are dominant pollinators in the northern hemisphere, providing important pollination services for commercial crops and innumerable wild plants. Nationwide declines several bumble bee species habitat losses multiple ecosystems have raised concerns about conservation of this group. In many regions, such as Palouse Prairie, relatively little is known communities, despite their critical ecosystem functions. Pitfall trap surveys ground beetles...

Abstract The influence of tillage, gender, and microclimate on capture rates pitfall traps for the beetles Poecilus scitulus LeConte, lucublandus (Say), Pterostichus melanarius Illiger (Coleoptera: Carabidae) were assessed in mark–release–recapture experiments spring pea wheat. Experiments conducted during June, July, August 2003 Palouse region northern Idaho, USA. Rates three carabid species differentially affected by crop‐tillage systems. Capture P. higher no‐till (NT) than conventional...

Silene spaldingii S Watson is a rare long-lived forb (Caryophyllaceae) found primarily in open native grasslands of the Inland Pacific Northwest and putatively pollinated by one key bumble bee pollinator, Bombus fervidus (Fabricius). However, populations bees their visitation patterns can vary dramatically, some species are decline including B. fervidus. Understanding role co-pollinators such as sweat (Halictidae) could be crucial plight plants pollinators intensifies. We collected data...

Abstract Conversion from conventional‐tillage (CT) to no‐tillage (NT) agriculture can affect pests and beneficial organisms in various ways. NT has been shown reduce the relative abundance feeding damage of pea leaf weevil (PLW), Sitona lineatus L.

Pitfall traps were used quantify tillage effects on activity‐density PLW field experiments conducted 2001 2002. As capture...

The parasitic wasp Mymaromella pala Huber and Gibson (Hymenoptera: Mymarommatidae) was collected at 4 sites within a canyon reach of the Kootenai River in Lincoln County, Montana. This minute species has only recently been described, but it appears to have large distribution throughout United States be associated with upland riparian forests.

Bumble bees are important pollinators of flowering plants, foraging and providing pollination services throughout the growing season. They adapted to cool temperatures among most all at high elevations northern latitudes. Over past several decades, multiple species bumble have experienced declines in both geographic range abundance Europe North America, while 4 genus Bombus (Bombus) suffered dramatic United States. Such not as evident Alaska, status remains relatively unknown adjacent...

LANDFIRE (LF) has been producing periodic spatially explicit vegetation change maps (i.e., LF disturbance products) across the entire United States since 1999 at a 30 m spatial resolution.

The recently described Oreoleptis torrenticola Zloty, Sinclair and Pritchard (Diptera: Tabanomorpha), belonging to the monotypic family Oreoleptidae, was previously from Northern Rocky Mountains of USA Canada. However, as part a broad, multidisciplinary study by Yakama Nation, 30 larvae O. were collected at multiple sites within Twisp River Cascade in Okanogan County, Washington, 2008–2010. This finding represents substantial range extension for species.

The Index of Biotic Integrity (IBI) is designed to measure the changes in ecological and environmental conditions as affected by human disturbances.
