Infectious hematopoietic necrosis virus: Monophyletic origin of European isolates from North American Genogroup M Infectious hematopoietic necrosis virus: Monophyletic origin of European isolates from North American Genogroup M
Infectious hematopoietic necrosis virus (IHNV) was first detected in Europe in 1987 in France and Italy, and later, in 1992, in Germany. The source of the virus and the route of introduction are unknown. The present study investigates the molecular epidemiology of IHNV outbreaks in Germany since its first introduction. The complete nucleotide sequences of the glycoprotein (G) and non...

The Columbia River Research Laboratory The Columbia River Research Laboratory
The U.S. Geological Survey's Columbia River Research Laboratory (CRRL) was established in 1978 at Cook, Washington, in the Columbia River Gorge east of Portland, Oregon. The CRRL, as part of the Western Fisheries Research Center, conducts research on fishery issues in the Columbia River Basin. Our mission is to: 'Serve the public by providing scientific information to support the...

A spatial model of potential jaguar habitat in Arizona A spatial model of potential jaguar habitat in Arizona
The jaguar (Panthera onca) is an endangered species that occasionally visits the southwestern United States from Mexico. The number of jaguar sightings per decade has declined over the last 100 years in Arizona, USA, raising conservation concerns for the species at a local and national level. In 1997, state, federal, and local governments with land-management responsibilities agreed to

Passage behavior of radio-tagged yearling Chinook salmon and steelhead at Bonneville Dam, 2004: Revised for corrected spill annual report Passage behavior of radio-tagged yearling Chinook salmon and steelhead at Bonneville Dam, 2004: Revised for corrected spill annual report
Flow augmentation, spill, surface collection, and improved turbine guidance systems have been identified as potential management actions to improve passage efficiency and survival of outmigrating juvenile salmonids. The U.S. Army Corps of Engineers (USACE), along with regional, state, and federal resource agencies, has designed and implemented studies to determine which management...

Fish can get diseases too Fish can get diseases too
Infectious diseases are increasingly recognized as an important component of the ecology of fish in the wild. Many of the viral, bacterial, protozoan and fungal pathogens of fish that were initially discovered in captive fish have their origin among wild populations; however, the impact of disease among these free-ranging stocks has been difficult to study. At the WFRC, combinations of...

Effects of turbidity, light level, and cover on predation of white sturgeon larvae by prickly sculpins Effects of turbidity, light level, and cover on predation of white sturgeon larvae by prickly sculpins
White sturgeon Acipenser transmontanus occur in rivers of the western United States and southwestern Canada, but some populations are in decline because of recruitment failure. Many river systems in this area have been altered as a result of development that has caused major environmental changes. Our goal was to examine how three changes - lower turbidity levels, higher light levels...

Effects of temperature on survival and development of early life stage Pacific and western brook lampreys Effects of temperature on survival and development of early life stage Pacific and western brook lampreys
We examined the effects of temperature (10, 14, 18, and 22??C) on survival and development of Pacific lampreys Lampetra tridentata and western brook lampreys L. richardsoni during embryological and early larval stages. The temperature for zero development was estimated for each species, and the response to temperature was measured as the proportion of individuals surviving to hatch...
