Biological monitoring of environmental quality: The use of developmental instability
Distributed robustness is thought to influence the buffering of random phenotypic variation through the scale-free topology of gene regulatory, metabolic, and protein-protein interaction networks. If this hypothesis is true, then the phenotypic response to the perturbation of particular nodes in such a network should be proportional to the number of links those nodes make with neighboring nodes.

Involvement of rainbow trout leucocytes in the pathogenesis of infectious hematopoietic necrosis
Rainbow trout Oncorhynchus myluss leucocytes were tested for their ability to support replication of infectious hematopoietic necrosis virus (IHNV). Viral replication occurred in vitro uslng leucocytes cultured from peripheral blood, kidney, and thymus where viral titers peaked at 2 to 4 d post-inoculation. Leucocytes collected from trout following waterborne challenge with IHNV were cocultured on

Application of the stage-projection model with density-dependent fecundity to the population dynamics of Spanish ibex
A stage-class population model with density-feedback term included was used to identify the most critical parameters determining the population dynamics of female Spanish ibex (Capra pyrenaica) in southern Spain. A population in the Cazorla and Segura mountains is rapidly declining, but the eastern Sierra Nevada population is growing. The stable population density obtained using estimated values o

Northern squawfish Ptychochelius oregonensis, O2 consumption rate: Effects of temperature and body size
Northern squawfish, Ptychocheilus oregonensis (live weight range 0.361–1.973 kg), O2consumption was measured with temperature-controlled, flow-through respirometers for >24 h. Mean standard O2 consumption rate of northern squawfish increased with acclimation temperature: 24.3, 49.1, 75.0, and 89.4 mg∙kg−0.67∙h−1 at 9, 15, 18, and 21 °C, respectively. Q10analysis showed that O2 consumption rate tem

Assessing smoltification of juvenile spring Chinook salmon Oncorhynchus tshawytscha using changes in body morphology
A morphometric measure of smoltification of juvenile spring chinook salmon (Oncorhynchus tshawytscha) was developed and evaluated. Fish were collected from hatcheries in Washington and Idaho prior to release and at McNary Dam on the Columbia River during their downstream migration. Distances between 15 anatomical landmarks were digitized from photographs of each fish resulting in 34 morphometric c

Developmental instability as an indicator of natural stress on the Pacific Hake (Merlussius productus)
Developmental lnstability (DI) has been proposed as an inexpensive, quickly applied, and sensitive indicator of stress that can be utilized in early warning and in monitoring anthropogenic impacts on fish and other animals and plants. A problem arises, however, to the extent that natural stressors confound the effects of human-induced disturbances. Our objective in this work was to investigate whe
