Snow Scorpionflies (Mecoptera: Boreidae) of the Hanford Reach National Monument

Boreidae are a small and intriguing family of insects in the order Mecoptera. Also called snow scorpionfiies, adults are active in the winter months and thus rarely collected. They are associated with mosses and other bryophytes on which they feed, plants that are prominent components of the biological soil crusts common in shrub-steppe environments. Large series of Boreus californicus, B.nix, and B. reductus were collected in pitfall traps and by hand during surveys conducted from 1998-2002, at what is now the Hanford Reach National Monument. Eleven collecting sites were pitfall trapped in winter during the study, with specimens collected at only three of the locations. All but one of the pitfall-trapped specimens came from two adjacent collecting sites. Specimens were also hand-collected from Rattlesnake Ridge, within 5km of the productive pitfall trap sites. Adults were collected from November through April but were most abundant in December and January. Sex ratios for all species and both collecting methods were generally male dominated. The continuous sampling during this project provides a rare look at the phenology and community composition of shrub-steppe Boreus but does little to elucidate Boreus spp. habitat selection.

Wild and Scenic Wasteland: Conservation Politics in the Nuclear Wilderness

Abstract Nuclear weapons production has created a unique geography of irradiated open space in the United States. In recent years, many of these landscapes have been re-classified as national wildlife refuges in an attempt to transform the nation's atomic sacrifice zones into spaces of environmental salvation. However, these areas are also home to contaminated biota that migrate beyond refuge boundaries, inspiring biological vector control campaigns that frame nuclear nature as a threat that must be contained. How can these environments simultaneously embody ruin and redemption, and what work does this constitutive contradiction do? In this article, I explore the slippery subjectivities of nuclear waste and nature at Washington State's Hanford Nuclear Reservation. Beginning with the Hanford Reach National Monument, I examine how this space is framed as both pristine habitat and waste frontier. Next, I consider how Hanford's biological vector control program addresses the spread of radioactive flora and fauna. Looking specifically at one of the site's most notorious offenders (the fruit fly), I discuss how vector control uses instances of nuclear trespass to articulate the boundary between contaminated and uncontaminated. Finally, by examining the dual production of nature as both untouched wilderness and biological vector, I consider how this slippage between pure and polluted has been employed in the service of nuclear industry. I argue that in its doubling, nature is being recruited to do what the U.S. Department of Energy cannot: to solve Hanford's nuclear waste problem.

New Records of Nematomorph Parasites (Nematomorpha: Gordiida) of Ground Beetles (Coleoptera: Carabidae) and Camel Crickets (Orthoptera: Rhaphidophoridae) In Washington State

From 1998 to 2003, beetles and crickets infected with hairworms were collected from 4 localities within the Hanford Nuclear Site and the Hanford Reach National Monument, located in a shrub-steppe region of Washington State along the Columbia River. Infected hosts comprised 6 species of carabid beetles within 5 genera and 2 camel crickets within 1 genus; all are newly documented insect-nematomorph associations. A large proportion of the infected hosts (48%) were collected from a single site during a single collecting period. Of the 38 infected hosts, 32 contained a single worm, 4 hosts contained 2 worms, and 2 hosts contained 3 worms. Five of the hosts with multiple infections contained at least 1 male and 1 female worm. Camel crickets were infected with Neochordodes occidentalis while carabids were infected with an undescribed species of Gordionus . As the majority of hairworms are collected in the post-parasitic adult phase, host data and hairworm-arthropod associations remain poorly documented and our work adds new data to this area of nematomorph biology.

European Earwig,Forficula auriculariaL. (Dermaptera: Forficulidae), at the Hanford Reach National Monument, Washington State

The European earwig, Forficula auricularia L., was surveyed using pitfall traps at 3 sites at the Hanford Reach National Monument in south central Washington State. Pitfall traps were collected weekly from April 2002 through April 2003. The earwig was consistently taken during all months of the year at a disturbed, weedy site along the Columbia River (White Bluffs Ferry site) but was rare or not collected in 2 less-disturbed shrubsteppe habitats. Highest numbers occurred during April-May, when immatures accounted for the majority of the catch; immatures reached the adult stage during mid-July, and the species is univoltine at the site. Possible reasons why earwigs have not colonized the monument's shrubsteppe habitat include the arid climate with lack of available moisture, especially for breeding purposes, and a lack of burrow sites.
