Blood sampling through the caudal vasculature is a widely used technique in fish biology for
investigating organismal health and physiology. In live fishes, it can provide a quick, easy …

The cellular stress response (CSR) is pervasive to all domains of life. It has shaped the
interaction between organisms and their environment since the origin of the first cell …

Many fish naturally encounter a daily cycle of hypoxia, but it is unclear whether this exposure
hardens hypoxia-intolerant fish to future hypoxia or leads to accumulated stress and death …

ABSTRACT these shifts; yet, research has only just begun to elucidate how these rapid
changes interact in this long-evolved, slowly repro-Globally, climate change is predicted to …

Vertebrate freeze tolerance requires multiple adaptations underpinned by specialized
biochemistry. Freezing of extracellular water leads to intracellular dehydration as pure water …

Biological rhythms that are mediated by exogenous factors, such as light and temperature,
drive the physiology of organisms and affect processes ranging from cellular to population …

Elasmobranch populations face worldwide declines owing to anthropogenic stressors, with
lethal and sub-lethal consequences. Oxygen uptake rates (̇ MM˙ O 2, typically measured in …

In animals discarded after a fishing capture event, the elicited stress response necessary to
ensure their survival is energetically costly. This energy is diverted from other important …

Anthropogenic practices have increased metal contamination in marine ecosystems. Most
sharks have long lifespans, occupy an important ecological position at the top of marine food …

Unlike other marine teleosts, the Plotosidae catfishes reportedly have an extra-branchial salt
