δ13C and δ15N Signatures in Muscle and Fin Tissues: Nonlethal Sampling Methods for Stable Isotope Analysis of SalmonidDownload
Stable isotope analysis has emerged as an important tool in aquatic ecology. For fish, dorsal muscle from sacrificed individuals has traditionally been used in stable isotope studies; however, there are many instances when lethal sampling is undesirable. We evaluated the feasibility of using...
γ-Aminobutyric Acid Up-Regulates the Expression of a Novel Secretogranin-II Messenger Ribonucleic Acid in the Goldfish PituitaryDownload
An RNA-arbitrarily primed PCR differential display strategy was used to identify candidate genes in the pituitary that are up-regulated by endogenously activated g-aminobutyric acid (GABA) systems that may also be involved in the control of reproduction. Goldfish were injected with the GABA...
cDNAs of cell adhesion molecules of different specificity induce changes in cell shape and border formation in cultured S180 cellsDownload
Abstract. The liver cell adhesion molecule (L-CAM) and N-cadherin or adherens junction-specific CAM (A-CAM) are structurally related cell surface glycoproteins that mediate calcium-dependent adhesion in different tissues. We have isolated and characterized a full-length cDNA clone for chicken...
A trophic cascade recently has been reported among wolves, elk, and aspen on the northern winter range of Yellowstone National Park, Wyoming, USA, but the mechanisms of indirect interactions within this food chain have yet to be established. We investigated whether the observed trophic cascade...
Wolf Reproduction in Response to Caribou Migration and Industrial Development on the Central Barrens of Mainland CanadaDownload
Reproductive success of mammals is greatly influenced by food availability. Where wolves (Canis lupus) prey on migratory barren-ground caribou (Rangifer tarandus), caribou migration patterns strongly influence food availability for wolves. However, industrial development in formerly undeveloped...
Reintroduction of wolves (Canis lupus) to Yellowstone National Park in 1995–1996 has been argued to promote a trophic cascade by altering elk (Cervus elaphus) density, habitat-selection patterns, and behavior that, in turn, could lead to changes within the plant communities used by elk. We...
Disease control by managers is a crucial response to emerging wildlife epidemics, yet the means of control may be limited by the method of disease transmission. In particular, it is widely held that population reduction, while effective for controlling diseases that are subject to...
Wild salmon sustain the effectiveness of parasite control on salmon farms: Conservation implications from an evolutionary ecosystem serviceDownload
Rapid evolution can increase or maintain the provision of ecosystem services, motivating the conservation of wild species and communities. We detail one such contemporary evosystem service by synthesizing theoretical evidence that rapid evolution can sustain parasiticide efficacy in salmon...
Whole-genome duplication and molecular evolution in Cornus L.(Cornaceae)–Insights from transcriptome sequencesDownload
The pattern and rate of genome evolution have profound consequences in organismal evolution. Whole-genome duplication (WGD), or polyploidy, has been recognized as an important evolutionary mechanism of plant diversification. However, in non-model plants the molecular signals of genome...
