Non-lethal sampling for the detection of Myxobolus cerebralis in asymptomatic rainbow trout Non-lethal sampling for the detection of Myxobolus cerebralis in asymptomatic rainbow trout
We have described in previous reports (Schill et al., 1998) the development of a polymerase chain reaction (PCR) amplification of 18S ribosomal RNA for the detection of Myxozoan parasites. Oligonucleotide primers were developed by multiple alignment of Myxozoan sequence information and analysis by a custom-written computer program (PRIM). Candidate pairs of primer sequences were then...

Pesticides in stream sediment and aquatic biota: distribution, trends, and governing factors Pesticides in stream sediment and aquatic biota: distribution, trends, and governing factors
More than 20 years after the ban of DDT and other organochlorine pesticides, pesticides continue to be detected in air, rain, soil, surface water, bed sediment, and aquatic and terrestrial biota throughout the world. Recent research suggests that low levels of some of these pesticides may have the potential to affect the development, reproduction, and behavior of fish and wildlife, and...

Snake species of the world: A taxonomic and geographic reference. v. 1 Snake species of the world: A taxonomic and geographic reference. v. 1
Given the absence of a current source on snake diversity and nomenclature and the expressed global need to understand better the diversity of our biota, we think that a catalogue of the world snake fauna complete with synonymies at the familial, generic, and specific levels is essential. We provide that here beginning with publication of the first volume. This compendium will facilitate

Studying wind energy/bird interactions: a guidance document. Metrics and methods for determining or monitoring potential impacts on birds at existing and proposed wind energy sites Studying wind energy/bird interactions: a guidance document. Metrics and methods for determining or monitoring potential impacts on birds at existing and proposed wind energy sites
In the 1980s little was known about the potential environmental effects associated with large scale wind energy development. Although wind turbines have been used in farming and remote location applications throughout this country for centuries, impacts on birds resulting from these dispersed turbines had not been reported. Thus early wind energy developments were planned, permitted...

Sustainable fisheries management: Pacific salmon Sustainable fisheries management: Pacific salmon
What has happened to the salmon resource in the Pacific Northwest? Who is responsible and what can be done to reverse the decline in salmon populations? The responsibly falls on everyone involved - fishermen, resource managers and concerned citizens alike - to take the steps necessary to ensure that salmon populations make a full recovery. This collection of papers examines the state of...
Tadpoles: the Biology of Anuran Larvae Tadpoles: the Biology of Anuran Larvae
The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, ecology, and evolutionary biology have focused enormous attention on tadpoles. Yet despite this growing interest, relatively little is known about these fascinating creatures. n this
Yellowstone and the biology of time: Photographs across a century Yellowstone and the biology of time: Photographs across a century
Established in 1872, Yellowstone National Park is the oldest and one of the largest national parks in the world. In this remarkable book, scientists Mary Meagher and Douglas B. Houston present 100 sets of photographs that compare the Yellowstone of old with the park of today. Most of the photo sets include three pictures-not the usual two-with many of the original views dating back to...
