Evolutionary rescue in a changing world.
Trends Ecol Evol. 2014 Jul 15;
Authors: Carlson SM, Cunningham CJ, Westley PA
Evolutionary rescue occurs when adaptive evolutionary change restores positive growth to declining populations and prevents extinction. Here we outline the diagnostic features of evolutionary rescue and distinguish this phenomenon from demographic and genetic rescue. We then synthesize the rapidly accumulating theoretical and experimental studies of evolutionary rescue, highlighting the demographic, genetic, and extrinsic factors that affect the probability of rescue.
Histopathologic alterations associated with global gene expression due to chronic dietary TCDD exposure in juvenile zebrafish.
PLoS One. 2014;9(7):e100910
Authors: Liu Q, Spitsbergen JM, Cariou R, Huang CY, Jiang N, Goetz G, Hutz RJ, Tonellato PJ, Carvan MJ
The goal of this project was to investigate the effects and possible developmental disease implication of chronic dietary TCDD exposure on global gene expression anchored to histopathologic analysis in juvenile zebrafish by functional genomic, histopathologic and analytic chemistry methods.
Genome-wide profiling of DNA methylation and gene expression in Crassostrea gigas male gametes.
Front Physiol. 2014;5:224
Authors: Olson CE, Roberts SB
DNA methylation patterns and functions are variable across invertebrate taxa. In order to provide a better understanding of DNA methylation in the Pacific oyster (Crassostrea gigas), we characterized the genome-wide DNA methylation profile in male gamete cells using whole-genome bisulfite sequencing.
Estimating Historical Eastern North Pacific Blue Whale Catches Using Spatial Calling Patterns.
PLoS One. 2014;9(6):e98974
Authors: Monnahan CC, Branch TA, Stafford KM, Ivashchenko YV, Oleson EM
Blue whales (Balaenoptera musculus) were exploited extensively around the world and remain endangered. In the North Pacific their population structure is unclear and current status unknown, with the exception of a well-studied eastern North Pacific (ENP) population.
Rearing in natural and recovering tidal wetlands enhances growth and life-history diversity of Columbia Estuary tributary coho salmon Oncorhynchus kisutch population.
J Fish Biol. 2014 May 28;
Authors: Craig BE, Simenstad CA, Bottom DL
This study provides evidence of the importance of tributary tidal wetlands to local coho salmon Oncorhynchus kisutch populations and life-history diversity. Sub-yearling and, to a lesser extent, yearling O.
Brain acetylcholinesterase activity in shiner perch (Cymatogaster aggregata) and juvenile chinook salmon (Oncorhynchus tshawytscha) after application of carbaryl to control burrowing shrimp within Willapa Bay, Washington.
Arch Environ Contam Toxicol. 2013 Nov;65(4):779-89
Authors: Troiano AT, King KA, Grue CE, Grassley JM, Ekblad CJ
Carbaryl has been applied in Willapa Bay, Washington, for five decades to control burrowing shrimp (Neotrypaea californiensis and Upogebia pugettensis) on commercial oyster (Crassostrea gigas) beds.
Gyrodactylid ectoparasites in a population of rainbow trout (Oncorhynchus mykiss).
J Am Assoc Lab Anim Sci. 2014 Jan;53(1):92-7
Authors: Garcia RL, Hansen AG, Chan MM, Sanders GE
A colony of rainbow trout (Oncorhynchus mykiss) in a decentralized aquatic animal facility was noted to have an increase in morbidity and mortality (from 4 or 5 fish each month to 3 or 4 fish daily) approximately 2 wk after experimental procedures began.
Spatial Scaling of Non-Native Fish Richness across the United States.
PLoS One. 2014;9(5):e97727
Authors: Guo Q, Olden JD
A major goal and challenge of invasion ecology is to describe and interpret spatial and temporal patterns of species invasions. Here, we examined fish invasion patterns at four spatially structured and hierarchically nested scales across the contiguous United States (i.e., from large to small: region, basin, watershed, and sub-watershed).
Quantitative PCR analysis used to characterize physiological changes in brain tissue of senescent sockeye salmon.
Biogerontology. 2013 Oct;14(5):483-90
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.
Patterns of ecosystem metabolism in the Tonle Sap Lake, Cambodia with links to capture fisheries.
PLoS One. 2013;8(8):e71395
Authors: Holtgrieve GW, Arias ME, Irvine KN, Lamberts D, Ward EJ, Kummu M, Koponen J, Sarkkula J, Richey JE
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.
