Invasion Routes and Evolution of Brook Stickleback (Culaea inconstans) in Eastern Washington
… to native ecosystems. In eastern Washington brook stickleback (Culaea inconstans) is an important invasive species, especially at Turnbull National Wildlife Refuge, where they compete with waterfowl for food resources and are associated with declines in habitat quality. Understanding the …

Assessing Brook Stickleback (Culaea inconstans) as a bioindicator for endocrine disrupting compounds in aquatic environments
… EDCs with (anti-)androgenic activity. Male sticklebacks build nests using spiggin, an androgen-responsive glycoprotein, which can be used to assess (anti-)androgenic exposure. EDC assessment in the field using threespine stickleback and the spiggin biomarker is limited to coastal and …

Sensory exploitation and condition indication may explain red pelvic spines in the brook stickleback Culaea inconstans
… in male Turnbull National Wildlife Refuge (TNWR) brook stickleback (Cu!aea inconstans) evolve to exploit a preexisting sensory bias for red prey, thus helping males draw females to the nest? Or, did it evolve as an intersexual signal indicating male condition to females? Methods: I recorded the …

Measuring variation in body morphology and life history traits in Brook Stickleback (Culaea inconstans), Eastern Washington, USA
… to migrate/disperse, among other factors. Brook stickleback (Culaea inconstans) have been a concern in eastern Washington since 1999 when they were discovered in water bodies on Turnbull National Wildlife Refuge. The purpose of this project was to describe potential variation in body …

Chemically-mediated prey responses: invasive brook stickleback induced changes in behavior and life history of larval long-toed salamanders
… elegans), tiger salamanders (A. tigrinum) and brook stickleback (Culaea inconstans), which had been fed a larvae-diet of A. macrodactylum or a null-diet of earthworms (Lumbricus terrestris), and measured subsequent changes in A. macrodactylum behavior. A. macrodactylum decreased activity in …

Seasonal infection of invasive Brook Stickleback (Culea inconstans) by the nematode Contracaecum multipapillatum at Turnbull National Wildlife Refuge, Washington
<p>The brook stickleback (Culaea inconstans) was first identified in Washington state in 1999 and has since established high population densities at Turnbull National Wildlife Refuge (TNWR). Fish parasitized by Contracaecum multipapillatum, a nematode known to infect zooplankton, piscivorous birds, …

Determining the effects of non-native brook stickleback (Cualea inconstans) on the lentic systems at Turnbull National Wildlife Refuge, Cheney, WA
… in ephemeral/temporary habitats. Non-native brook stickleback fishes (Culaea inconstans) were first documented on the Turnbull National Wildlife Refuge (WA) in 1999 and are now present in many portions of the refuge. The consequences of their presence on the refuge's perennial/permanent and …

Impacts of the invasive Brook Stickleback (Culaea inconstans) on wandering garter snake (Thamnophis elegans vagrans) fitness, feeding behavior and diet
… mass index, recorded garter snakes feeding on brook stickleback in the lab and analyzed the presence/absence of prey DNA in their feces. While snakes from the stickleback-present site had shorter SVL and lower mass, there was not a significant difference in fitness. In the laboratory feeding …

Differentiating the effects of two non-native fish in the Turnbull National Wildlife Refuge
… individual effects of two non-native fish, the brook stickleback, Culaea inconstans, and pumpkinseed, Lepomis gibbosus, on the aquatic invertebrates and food webs of Turnbull National Wildlife Refuge (TNWR). Ten ponds were analyzed and compared with stable isotope analysis and invertebrate …

Invasive fish effects on the invertebrate constituents of wetland communities
… waterfowl using stable isotope analysis. Brook stickleback (Culaea inconstans) and pumpkinseed (Lipomis gibbosus) pose a potentially growing threat to temperate Pacific drainages of North America due to their ability to outcompete native fauna. Our study compares and contrasts the …

A macroinvertebrate bioassessment of two streams on Turnbull National Wildlife Refuge (TNWR)
… TNWR. This stream has high densities of invasive brook stickleback, and experiences nutrient loading from an unknown source.</p> <p>Both streams were assessed using benthic macroinvertebrate surveys in 2007, 2008, 2010, 2011, 2013, and sampled again 2016. Benthic macroinvertebrate communities are …
