Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, EarlyView.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

Lake sturgeon (Acipenser fulvescens) growth and longevity estimated from adult capture–mark–recapture data

Journal of Fish Biology, EarlyView.
Abstract Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species.

High‐throughput multispecies quantitative polymerase chain reaction assays to study the effects of acute thermal stress in three species of Acipenser sturgeon

Journal of Fish Biology, EarlyView.
Abstract Fishes experience thermal stress in their natural environment that can be caused by natural or anthropogenic factors and can directly affect their physiology. In this study, we developed a multispecies OpenArray™ qPCR (quantitative polymerase chain reaction) ‘chip’ to measure the effects of acute thermal stress on the mRNA response of ...

Comparative study on the effects of different feeding habits and diets on intestinal microbiota in Acipenser baeri Brandt and Huso huso

BMC Microbiology, 2019
Background Siberian sturgeon (Acipenser baeri Brandt) and Beluga sturgeon (Huso huso) are two important commercial fish in China, and the feeding habits of them are very different.

Cultural and Economic Grievances and the Political Salience of Secessionism

Nations and Nationalism, EarlyView.
ABSTRACT Why does secessionism become politically salient at some times but recede at others? Existing work highlights how cultural and economic grievances can shape secessionism, but it explains less well when these claims elevate the salience of secessionism and why similar grievances matter in some contexts but not others.

qPCR detection of Sturgeon chub (Macrhybopsis gelida) DNA in environmental samples.

PLoS ONE, 2018
The Sturgeon chub (Macrhybopsis gelida) is a cyprinid fish native to the Missouri and Mississippi River basins of the U.S. Suspected long-term declines in the size of its distribution have prompted a review of its conservation status by the U.S. Fish and

Tackling Poverty Across the United Kingdom. Devolution, Difference and Discourse

IPPR Progressive Review, EarlyView.
ABSTRACT The UK welfare state is often considered as being highly centralised, yet the design and administration of UK social security involves significant spatial variations in law, policy, and practice. As such, where you live in the UK can affect the value of benefits and cash transfers you are entitled to, as well as how you experience benefit ...
