Differential propagation of the metazoan parasite Myxobolus cerebralis by Limnodrilus hoffmeisteri, Ilyodrilus templetoni, and genetically distinct strains of Tubifex tubifex Differential propagation of the metazoan parasite Myxobolus cerebralis by Limnodrilus hoffmeisteri, Ilyodrilus templetoni, and genetically distinct strains of Tubifex tubifex
Whirling disease, caused by the parasite Myxobolus cerebralis, has infected rainbow trout (Oncorhynchus mykiss) and other salmonid fish in the western United States, often with devastating results to native populations but without a discernible spatial pattern. The parasite develops in a complex 2-host system in which the aquatic oligochaete Tubifex tubifex is an obligate host. Because...

Cloning, expression, cellular distribution, and role in chemotaxis of a C5a receptor in rainbow trout: The first identification of a C5a receptor in a nonmammalian species Cloning, expression, cellular distribution, and role in chemotaxis of a C5a receptor in rainbow trout: The first identification of a C5a receptor in a nonmammalian species
C3a, C4a, and C5a anaphylatoxins generated during complement activation play a key role in inflammation. C5a is the most potent of the three anaphylatoxins in eliciting biological responses. The effects of C5a are mediated by its binding to C5a receptor (C5aR, CD88). To date, C5aR has only been identified and cloned in mammalian species, and its evolutionary history remains ill-defined...

Bi-parentally inherited species-specific markers identify hybridization between rainbow trout and cutthroat trout subspecies Bi-parentally inherited species-specific markers identify hybridization between rainbow trout and cutthroat trout subspecies
Eight polymerase chain reaction primer sets amplifying bi-parentally inherited species-specific markers were developed that differentiate between rainbow trout (Oncorhynchus mykiss) and various cutthroat trout (O. clarki) subspecies. The primers were tested within known F1 and first generation hybrid backcrosses and were shown to amplify codominantly within hybrids. Heterozygous...

White sturgeon mitigation and restoration in the Columbia and Snake rivers upstream from Bonneville Dam, Annual progress report April 2002 - March 2003. Report C White sturgeon mitigation and restoration in the Columbia and Snake rivers upstream from Bonneville Dam, Annual progress report April 2002 - March 2003. Report C
During 1 April 2002 through 31 March 2003, the U.S. Geological Survey (USGS) continued work on several tasks, including quantifying habitat suitable for white sturgeon Acipenser transmontanus spawning, a long-term survey of young-of-the-year (YOY) white sturgeon recruitment in the lower Columbia River, and a laboratory study investigating predation on larval and juvenile white sturgeon...

Habitat disturbance and the diversity and abundance of ants (Formicidae) in the Southeastern Fall-Line Sandhills Habitat disturbance and the diversity and abundance of ants (Formicidae) in the Southeastern Fall-Line Sandhills
We examined habitat disturbance, species richness, equitability, and abundance of ants in the Fall-Line Sandhills, at Fort Benning, Georgia. We collected ants with pitfall traps, sweep nets, and by searching tree trunks. Disturbed areas were used for military training; tracked and wheeled vehicles damaged vegetation and soils. Highly disturbed sites had fewer trees, diminished ground...

Prevalence of the parasitic copepod Haemobaphes intermedius on juvenile buffalo sculpins from Washington State Prevalence of the parasitic copepod Haemobaphes intermedius on juvenile buffalo sculpins from Washington State
The parasitic copepod, Haemobaphes intermedius, was detected in 62% of juvenile buffalo sculpins Enophrys bison, a previously unreported host, from the San Juan Islands archipelago in Washington State. Most infestations were characterized by the presence of a single female copepod infestations with multiple H. intermedius occurred either unilaterally or bilaterally in 29% of parasitized

Molecular methods for discriminating taxa, monitoring species, and assessing fungal diversity Molecular methods for discriminating taxa, monitoring species, and assessing fungal diversity
Exiting new molecular approaches that allow investigators to assess fungal biodiversity directly are being developed. These approaches are still in their infancies, but they are developing rapidly. The following papers provide an introduction to this burgeoning field of study: Bohannan and Hughes (2003), Cooksey (1997), Jumpponen (2003), Landeweert et al. (2003), Nikolchva et al. (2003)...
