Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

open access: yesJournal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

Ontogenetic niche partitioning in a facultatively anadromous salmonid: Implications for population dynamics

open access: yesGlobal Ecology and Conservation
Species management and conservation efforts are often based on range-wide trends, assuming dynamic equilibrium across space and time, even though fine-scale variability may be driving local dynamics.

Bony fish genomes: Status and gaps

open access: yesJournal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

open access: yesJournal of Fish Biology, EarlyView.
Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

An assessment of organic solvent based equilibrium partitioning methods for predicting the bioconcentration behavior of perfluorinated sulfonic acids, carboxylic acids, and sulfonamides [PDF]

open access: yes, 2009
SPARC, KOWWIN, and ALOGPS octanol-water partitioning (log K~ow~) and distribution (log D) constants were calculated for all C~1~ through C~8~ and the straight chain C~9~ through C~15~ perfluoroalkyl sulfonic acids (PFSAs) and carboxylic acids (PFCAs ...

Histological characterisation of gonadal sex differentiation in Malabar red snapper (Lutjanus malabaricus) for aquaculture advancement

open access: yesJournal of Fish Biology, EarlyView.
Abstract The Malabar red snapper (Lutjanus malabaricus) is a high‐value tropical marine species receiving growing attention for aquaculture development in Singapore and Southeast Asia. At present, seed production relies primarily on uncontrolled mass spawning in sea cages, a practice that lacks consistency, biosecurity and control of genetic ...
