Whole-genome duplication and molecular evolution in Cornus L.(Cornaceae)–Insights from transcriptome sequences
Download2017-02-22
YU, Yan, Soltis, Douglas E, Cheng, Shifeng , Wong, Gane , Manos, Paul S, Song, Bao-Hua , Liu, Xin , Soltis, Pamela S , Xiang, Qiuyun
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...

Wild salmon sustain the effectiveness of parasite control on salmon farms: Conservation implications from an evolutionary ecosystem service
Download2018-01-01
Kreitzman, Maayan, Ashander, Jaime, Driscoll, John, Bateman, Andrew W., Chan, Kai M.A., Lewis, Mark A., Krkošek, Martin
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...

Potapov, A., Merrill, E., Lewis, M.A.
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...

Merrill, E., Varley, N., Boyce, M. S., Beyer, H. L.
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...

Windsor Reid, Pamela J., Matveev, Eugueni, McClymont, Alexandra, Posfai, Dora, Hill, April L., Leys, Sally P.
Background: The Wnt signaling pathway is uniquely metazoan and used in many processes during development, including the formation of polarity and body axes. In sponges, one of the earliest diverging animal groups, Wnt pathway genes have diverse expression patterns in different groups including...

Wolf Reproduction in Response to Caribou Migration and Industrial Development on the Central Barrens of Mainland Canada
Download2008
Cluff, H.D., Frame, P.F., Hik, D.S.
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...

Wolves Influence Elk Movements: Behavior Shapes a Trophic Cascade in Yellowstone National Park
Download2005
Fortin, D., Beyer, H. L., Smith, D. W., Boyce, M. S., Mao, J. S., Duchesne, T.
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...

γ-Aminobutyric Acid Up-Regulates the Expression of a Novel Secretogranin-II Messenger Ribonucleic Acid in the Goldfish Pituitary
Download1998
Docherty, K., Chang, J.P., Blázquez, M., Trudeau, V.L., Bosma, P.T.
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...

δ13C and δ15N Signatures in Muscle and Fin Tissues: Nonlethal Sampling Methods for Stable Isotope Analysis of Salmonid
Download2010
Paszkowski, C.A., Hanisch, J.R., Tonn, W.M., Scrimgeour, G.J.
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...
