Differential growth in estuarine and freshwater habitats indicated by plasma IGF1 concentrations and otolith chemistry in Dolly Varden Salvelinus malma.
J Fish Biol. 2014 Aug 12;
Authors: Bond MH, Beckman BR, Rohrbach L, Quinn TP
This study employed a combination of otolith microchemistry to indicate the recent habitat use, and plasma concentrations of the hormone insulin-like growth factor 1 (IGF1) as an index of recent growth rate, to demonstrate differences in growth and habitat use by Dolly Varden Salvelinus malma occupying both freshwater and estuarine habitats in south-west Alaska.
Comparative genome mapping between Chinook salmon (Oncorhynchus tshawytscha) and rainbow trout (O. mykiss) based on homologous microsatellite loci.
G3 (Bethesda). 2013 Dec;3(12):2281-8
Authors: Naish KA, Phillips RB, Brieuc MS, Newton LR, Elz AE, Park LK
Comparative genome mapping can rapidly facilitate the transfer of DNA sequence information from a well-characterized species to one that is less described. Chromosome arm numbers are conserved between members of the teleost family Salmonidae, order Salmoniformes, permitting rapid alignment of large syntenic blocks of DNA between members of the group.

Shoreline modifications, such as seawall armoring and piers, are ubiquitous along developed waterfronts worldwide, and recent research suggests that their ecological effects are primarily negative.Read more
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.
