Isolates of viral hemorrhagic septicemia virus from North America and Europe can be detected and distinguished by DNA probes Isolates of viral hemorrhagic septicemia virus from North America and Europe can be detected and distinguished by DNA probes
Biotinylated DNA probes were constructed to hybndize with speclfic sequences within the messenger RNA (mRNA) of the nucleoprotein (N) gene of vlral hemorrhagic septicemia virus (VHSV) reference strains from Europe (07-71) and North Arnenca (Makah) Probes were synthesized that were complementary to (1) a 29-nucleotide sequence near the center of the N gene conlmon to both the 07-71 and...

Seasonal changes in cortisol sensitivity and glucocorticoid receptor affinity and number in leukocytes of coho salmon Seasonal changes in cortisol sensitivity and glucocorticoid receptor affinity and number in leukocytes of coho salmon
To determine if there were organ-specific changes in immune responses or immune-endocrine interaction, we monitored in vitro immune response, cortisol sensitivity and number and affinity of glucocorticoid receptors (GR) in leukocytes from freshwater-adapted juvenile coho salmon (Oncorhynchus kisutch) during the physiological changes that prepare them to enter the marine environment...

Identification of a whitefly species by genomic and behavioral studies Identification of a whitefly species by genomic and behavioral studies
An introduced whitefly species, responsible for over a half billion dollars in damage to U.S. agricultural production in 1991, is morphologically indistinguishable from Bemisia tabaci (Gennadius). However, with the use of polymerase chain reaction-based DNA differentiation tests, allozymic frequency analyses, crossing experiments, and mating behavior studies, the introduced whitefly is...

Modeling the response of native steelhead to hatchery supplementation programs in an Idaho River Modeling the response of native steelhead to hatchery supplementation programs in an Idaho River
A life history model was used to predict the response of native steelhead Oncorhynchus mykiss in the Lochsa River, Idaho, to long-term supplementation with hatchery fry and smolts. The four key factors affecting the response of the native fish to a stocking program were (1) the number of native spawners, (2) the number of stocked fish, (3) the number and fitness of progeny from stocked...

Survival in pond water of four reoviruses isolated from aquatic animals Survival in pond water of four reoviruses isolated from aquatic animals
The viabilities of golden shiner virus (GSV), chum salmon virus (CSV), oyster reovirus 13P2 (13P2). and catfish reovirus (CRV) were compared following viruses incubation in pond water samples held at 4°. 20°, 25°, and 30°C for one month. At the three higher temperatures tested, viral infectivity was lost by day 15 for GSV, day 20 for CSV, and day 10 for CRV and 13P2. At 4°C. no...

Annual and Spatial Variation of the Kelp Forest Fish Assemblage at San Nicolas Island, California Annual and Spatial Variation of the Kelp Forest Fish Assemblage at San Nicolas Island, California
The kelp forest fishes of San Nicolas Island, California were studied from 1981-1986 to examine the causes of among-site and among-year variation in the fish assemblages. Fish counts and seven physical and biological variables were recorded at six sites around the island every spring and fall. Over the study period, a total of 45 fish species from 18 families were recorded, though...

Differentiation of bacterial feeding nematodes in soil ecological studies by means of arbitrarily primed PCR Differentiation of bacterial feeding nematodes in soil ecological studies by means of arbitrarily primed PCR
Arbitrarily-primed polymerase chain reaction (ap-PCR) was used to differentiate closely related bacterial-feeding nematodes of the genera: Caenorhabditis, Acrobeloides, Cephalobus and Zeldia. Average percentage similarity of bands generated by ap-PCR with seven different primers between 14 isolates of Caenorhabditis elegans was ⪢ 90%, whereas between C. elegans, C. briggsae and C...
