Environmental signals act primarily on physiological systems, which then influence higher‐
level functions such as movement patterns and population dynamics. Increases in average …

Thermal acclimation causes the heart of some fish species to undergo significant
remodelling. This includes changes in electrical activity, energy utilization and structural …

Understanding the capacity of species to acclimate and adapt to expected temperature
increases is critical for making predictions about the biological impacts of global warming …

In fishes, performance failure at high temperature is thought to be due to a limitation on
oxygen delivery (the theory of oxygen and capacity limited thermal tolerance, OCLTT), which …

Given the predicted effects of climate change on seawater temperatures and water oxygen
levels (ie, the frequency and severity of hypoxia), it is important to understand the impact of …

Anthropogenic activities are greatly altering the habitats of animals, whereby fish are already
encountering several stressors simultaneously. The purpose of the current study was to …

Herein, we consider the heart as an organ whose task is to supply blood flow to the tissues.
A brief section on the form and function of the heart sets the stage for more detailed sections …

This chapter reviews the influence of environmental temperature on the cardiovascular
system. Specifically, we examine how the cardiovascular system responds to both acute and …

Environmental temperature has pervasive effects on the rate of life processes in ectothermic
animals. Animal performance is affected by temperature, but there are finite thermal limits for …

We investigated how acclimation to 8, 4 and 1 C, and acute cooling from 8 to 1 C, affected
the Atlantic salmon's aerobic and anaerobic metabolism, and cardiac function, during a …
