High-throughput sequencing and pathway analysis reveal alteration of the pituitary transcriptome by 17α-ethynylestradiol (EE2) in female coho salmon, Oncorhynchus kisutch.

Considerable research has been done on the effects of endocrine disrupting chemicals (EDCs) on reproduction and gene expression in the brain, liver and gonads of teleost fish, but information on impacts to the pituitary gland are still limited despite its central role in regulating reproduction.
How stock of origin affects performance of individuals across a meta-ecosystem: an example from sockeye salmon.
PLoS One. 2013;8(3):e58584
Authors: Griffiths JR, Schindler DE, Seeb LW
Connectivity among diverse habitats can buffer populations from adverse environmental conditions, influence the functioning of meta-ecosystems, and ultimately affect the reliability of ecosystem services. This stabilizing effect on populations is proposed to derive from complementarity in growth and survival conditions experienced by individuals in the different habitats that comprise meta-ecosystems.
Effects of management tactics on meeting conservation objectives for Western North American groundfish fisheries.
PLoS One. 2013;8(2):e56684
Authors: Melnychuk MC, Banobi JA, Hilborn R
There is considerable variability in the status of fish populations around the world and a poor understanding of how specific management characteristics affect populations. Overfishing is a major problem in many fisheries, but in some regions the recent tendency has been to exploit stocks at levels below their maximum sustainable yield.
Predation by bears drives senescence in natural populations of salmon.
PLoS One. 2007;2(12):e1286
Authors: Carlson SM, Hilborn R, Hendry AP, Quinn TP
Classic evolutionary theory predicts that populations experiencing higher rates of environmentally caused (“extrinsic”) mortality should senesce more rapidly, but this theory usually neglects plausible relationships between an individual’s senescent condition and its susceptibility to extrinsic mortality.
Development and application of genomic tools to the restoration of green abalone in southern California

Patterns of ecosystem metabolism in the tonle sap lake, cambodia with links to capture fisheries.

The Tonle Sap Lake in Cambodia is a dynamic flood-pulsed ecosystem that annually increases its surface area from roughly 2,500 km(2) to over 12,500 km(2) driven by seasonal flooding from the Mekong River.
Quantitative PCR analysis used to characterize physiological changes in brain tissue of senescent sockeye salmon.
Biogerontology. 2013 Aug 15;
Authors: Storer CS, Quinn TP, Roberts SB
Senescence varies considerably among fishes, and understanding the evolutionary basis for this diversity has become an important area of study. For rapidly senescing species such as Pacific salmon, senescence is a complex process as these fish are initiating anorexia while migrating to natal spawning grounds, and die within days of reproduction.
Sensitivity of salmonid freshwater life history in western US streams to future climate conditions.
Glob Chang Biol. 2013 Aug;19(8):2547-56
Authors: Beer WN, Anderson JJ
We projected effects of mid-21st century climate on the early life growth of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss) in western United States streams. Air temperature and snowpack trends projected from observed 20th century trends were used to predict future seasonal stream temperatures.
Riding the crimson tide: mobile terrestrial consumers track phenological variation in spawning of an anadromous fish.
Biol Lett. 2013;9(3):20130048
Authors: Schindler DE, Armstrong JB, Bentley KT, Jankowski K, Lisi PJ, Payne LX
When resources are spatially and temporally variable, consumers can increase their foraging success by moving to track ephemeral feeding opportunities as these shift across the landscape; the best examples derive from herbivore-plant systems, where grazers migrate to capitalize on the seasonal waves of vegetation growth.
The soundscapes of lakes across an urbanization gradient.
PLoS One. 2013;8(2):e55661
Authors: Kuehne LM, Padgham BL, Olden JD
UNLABELLED: BACKGROUND/METHODOLOGY: A significant implication of increasing urbanization is anthropogenic noise pollution. Although noise is strongly associated with disruption of animal communication systems and negative health effects for humans, the study of these consequences at ecologically relevant spatial and temporal scales (termed soundscape ecology) is in early stages of application.
