This review is focused on the questions of why fish exhibit heat failure at thermal extremes
and which physiological mechanisms determine the acute upper thermal tolerance. We …

Ongoing climate change has already been associated with increased disease outbreaks in
wild and farmed fish. Here, we evaluate the current knowledge of climate change-related …

Laboratory-based research dominates the fields of comparative physiology and
biomechanics. The power of lab work has long been recognized by experimental biologists …

Species persistence in the Anthropocene is dramatically threatened by global climate
change. Large emissions of carbon dioxide (CO 2) from human activities are driving …

Atlantic salmon (Salmo salar) reared in sea-cages in Atlantic Canada and Iceland can be
exposed to temperatures as low as 0–1° C during the winter months, and this can result in …

Behavioural analysis has been attracting significant attention as a broad indicator of sub‐
lethal toxicity and has secured a place as an important subdiscipline in ecotoxicology …

Amphibians and fishes play a central role in sha** the structure and function of freshwater
environments. These organisms have a limited capacity to disperse across different habitats …

All animals must acquire food to grow, but there is a vast diversity in how different species
and even different individuals approach and achieve this task. Individuals within a species …

Cold acclimation of zebrafish causes changes to the structure and composition of the heart.
However, little is known of the consequences of these changes on heart function or if these …

Estimates of organismal thermal tolerance are frequently used to assess physiological risk
from warming, yet the assumption that these estimates are predictive of mortality has been …
