Genes, fish and fisheries: translating science into policy
Journal of Fish Biology, EarlyView.Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Optimizing Selection of Brown Bear Hair for Noninvasive Genetic Analysis
Wildlife Society Bulletin, 2020 Many wildlife studies use noninvasive survey methods such as barbed wire to obtain hair samples for DNA analysis. If laboratory costs preclude processing all samples, it may be important to know a priori which samples are most likely to yield useful DNA.

Nature Conservation Research: Заповедная наука, 2021 We studied the behavioural ecology of Ursus arctos (hereinafter – brown bear or bear) in the basin of Lake Kurilskoe (Kamchatka Peninsula) in the summer and autumn of 2017–2018. The aim of this study was a comparative assessment of the behaviour of brown

Journal of Fish Biology, EarlyView.Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

Two Types of cDNAs Encoding Proopiomelanocortin of Sockeye Salmon, Oncorhynchus nerka [PDF]
Zoological Science, 1996 To investigate regulatory mechanisms of proopiomelanocortin (POMC) gene expression in sockeye salmon, we have isolated and characterized cDNAs encoding two types of sockeye salmon POMC, which are referred to as ssPOMC-A and -B. Two types of PCR products were amplified from total RNA of sockeye salmon pituitaries by use of rainbow trout sequences.

Heat exchange rates between adult sockeye salmon (Oncorhynchus nerka) and the environment
Journal of Fish Biology, EarlyView.Abstract Body temperatures of salmon do not always match the temperatures of their immediate environment. We investigated the relationship between varying ambient water temperatures and body temperatures of adult sockeye salmon Oncorhynchus nerka using Newton's law of cooling and non‐linear mixed models.

A Generalizable Tool for Predicting Developmental Phenology for Wild Ecotherms
Ecology and Evolution, Volume 16, Issue 8, August 2026.Custom hatch timing models developed for four North American Lithobates frog species. Models are parameterized from Moore (1939). Panels (A, B) shows differential developmental rates under varying thermal regimes and G × E interactions. ABSTRACT Development in poikilothermic organisms is strongly temperature‐dependent, particularly during early life ...
