Developmental instability analysis of BKD-infected spring Chinook salmon (Onchorhynchus tshawytscha) prior to seawater exposure Developmental instability analysis of BKD-infected spring Chinook salmon (Onchorhynchus tshawytscha) prior to seawater exposure

Stress in organisms results in energy dissipation, making developmental pathways less stable. Effects of chronic stress, manifested as small random departures from phenotypic symmetry, reflect developmental instability, are considered to be epigenetic and an effect produced by compromised fitness. Instability is detectable and effectively interpreted among sites or populations if samples...

The impact of grazing on plant fractal architecture and fitness of a mediterranean shrub (Anthyllis cytisoides L.) The impact of grazing on plant fractal architecture and fitness of a mediterranean shrub (Anthyllis cytisoides L.)

1. We examined natural grazing by livestock (sheep and goats) on Albaida Anthyllis cytisoides L. with the aim of determining whether variation in the allometric relationships between plant parts provides a sensitive indicator of the impact of grazing. 2. The intra-individual variation in translatory symmetry with scale and increased complexity of fractal structures reflect environmental...

The North American strain of viral hemorrhagic septicemia virus is highly pathogenic for laboratory-reared Pacific herring (Clupea pallasi) The North American strain of viral hemorrhagic septicemia virus is highly pathogenic for laboratory-reared Pacific herring (Clupea pallasi)

Specific-pathogen-free Pacific herring Clupea pallasi were reared in the laboratory from eggs and then challenged at 5, 9, and 13 months of age by waterborne exposure to low (101.5–2.5 plaque-forming units [PFU] per milliliter), medium (103.5–4.5 PFU/mL), or high (105.5–6.5 PFU/mL) levels of a North American isolate of viral hemorrhagic septicemia virus (VHSV). The fish were extremely...

Renibacterium salmoninarum in spring-summer Chinook salmon smolts at dams on the Columbia and Snake Rivers Renibacterium salmoninarum in spring-summer Chinook salmon smolts at dams on the Columbia and Snake Rivers

We evaluated Renibaeterium salmoninarum infection in smolts of hatchery and wild spring-summer Chinook salmon Oncorhynchus tshawytscha sampled during most of the outmigration at Little Goose (1988) and Lower Granite dams (1988–1991) on the Snake River and at Priest Rapids and McNary dams on the Columbia River (1988–1990). We sampled 860–2,178 fish per dam each year. Homogenates of kidney...

Characterization of a linear DNA plasmid from the filamentous fungal plant pathogen Glomerella musae [Anamorph: Colletotrichum musae (Berk. and Curt.) arx.] Characterization of a linear DNA plasmid from the filamentous fungal plant pathogen Glomerella musae [Anamorph: Colletotrichum musae (Berk. and Curt.) arx.]

A 7.4-kilobase (kb) DNA plasmid was isolated from Glomerella musae isolate 927 and designated pGML1. Exonuclease treatments indicated that pGML1 was a linear plasmid with blocked 5' termini. Cell-fractionation experiments combined with sequence-specific PCR amplification revealed that pGML1 resided in mitochondria. The pGML1 plasmid hybridized to cesium chloride-fractionated nuclear DNA...
