Results of long-term biological monitoring of pacific salmons in the hatcheries of Kamchatsky Krai

Известия ТИНРО, 2015
The following biological problems of the pacific salmons cultivation in Kamchatka are considered on the base of long-term monitoring data (2001-2013): 1) dynamics of cultivated salmons abundance in the water bodies of salmon hatcheries; 2) salmon otolith

Evidence of parental care as a newly identified reproductive isolating barrier

Journal of Animal Ecology, EarlyView.
Behavioural variation can contribute to reproductive isolation and can be an important driver of speciation. Here, we show that a previously undescribed mechanism, parental care, can function as a postzygotic reproductive isolating barrier when dysregulated in hybrids.

Paler within the city: Carotenoid‐based colouration covaries negatively with the proportion of impervious surface in great tit (Parus major) territories across Europe

Journal of Animal Ecology, EarlyView.
Across six European cities, great tits in more impervious territories had paler carotenoid‐based plumage, but not lower brightness or UV chroma. This suggests that urban habitat imperviousness is associated specifically with lower carotenoid pigment deposition, rather than broad changes in feather reflectance or structural quality.

Comparison of infectious agents detected from hatchery and wild juvenile Coho salmon in British Columbia, 2008-2018.

PLoS ONE, 2019
Infectious diseases are potential contributors to decline in Coho salmon (Oncorhynchus kisutch) populations. Although pathogens are theoretically considered to pose higher risk in high-density rearing environments like hatcheries, there is no direct ...

Spatiotemporal distribution of Ceratonova shasta in the lower Columbia River Basin and effects of exposure on survival of juvenile chum salmon Oncorhynchus keta.

PLoS ONE, 2022
In the Columbia River Basin (CRB), USA, anthropogenic factors ranging from dam construction to land use changes have modified riverine flow and temperature regimes and degraded salmon habitat.

Compounding Impacts-Genomic Exploration of the Potential Effect of Domestic Introgression on Climate Adaptation in Atlantic Salmon (<i>Salmo salar</i>). [PDF]

Evol Appl
ABSTRACT Predicting population, species, and community responses to climate change is critical for the successful management of wild ecosystems. However, climate change does not act alone. Interactions among climate change and other anthropogenic threats could significantly complicate predictions of global change yet have rarely been examined.

Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

Integrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...

Disputing nature in the Anthropocene: technology as friend and foe in the struggle to conserve wild Atlantic salmon (Salmo salar)

Ecology and Society, 2019
The Anthropocene, simply put, is characterized by the recognition that natural processes are inextricably entwined with human influence. Against this backdrop, managing natural resources needs to be fundamentally rethought as balancing human-nature ...

Age and length composition of Columbia Basin chinook, sockeye, and coho salmon at Bonneville Dam in 2001 [PDF]

, 2002
In 2001, representative samples of adult Columbia Basin chinook (Oncorhynchus tshawytscha), sockeye (O. nerka), and coho salmon (O. kisutch) populations at Bonneville Dam were collected.

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

Conservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...
