Critical oxygen tensions as predictors of hypoxia tolerance and tissue metabolic responses during hypoxia exposure in fishes

B Speers-Roesch, M Mandic, DJE Groom… - Journal of Experimental …, 2013 - Elsevier
An organism's critical oxygen tension (P crit) reflects its ability to extract environmental O 2.
Consequently, P crit has been used as an indicator of hypoxia tolerance in aquatic animals …

Cardiovascular function and cardiac metabolism

AK Gamperl, WR Driedzic - Fish physiology, 2009 - Elsevier
Next to extremes in temperature, hypoxia is arguably the most significant environmental
challenge faced by fishes. This is because of the disruptions/consequences it has for the …

N El, MH Christjansen, EC Smallwood… - Journal of …, 2025 - journals.biologists.com
Upper thermal tolerance may be limited by convective oxygen transport in fish, but the
mechanisms constraining heart function remain elusive. The activation of anaerobic …

Changes in food intake and glucosensing function of hypothalamus and hindbrain in rainbow trout subjected to hyperglycemic or hypoglycemic conditions

S Polakof, JM Míguez, JL Soengas - Journal of Comparative Physiology A, 2008 - Springer
To evaluate the possible role of glucose in the control of food intake (FI) in fish and the
involvement of glucosensing system in that role, we have subjected rainbow trout (via …

Cardiorespiratory toxicity of environmentally relevant zinc oxide nanoparticles in the freshwater fish Catostomus commersonii

RA Bessemer, KMA Butler, L Tunnah… - …, 2015 - Taylor & Francis
The inhalation of zinc oxide engineered nanomaterials (ENMs) has been linked to
cardiorespiratory dysfunction in mammalian models but the effects of aquatic ENM exposure …

Altered dietary carbohydrates significantly affect gene expression of the major glucosensing components in Brockmann bodies and hypothalamus of rainbow trout

S Polakof, S Panserat… - American Journal of …, 2008 - journals.physiology.org
Carnivorous fish have a limited capacity to utilize dietary carbohydrates even though
glucosensing components exist in the hypothalamus and Brockmann bodies. Therefore, we …

Exposure of European sea bass (Dicentrarchus labrax) to chemically dispersed oil has a chronic residual effect on hypoxia tolerance but not aerobic scope

Y Zhang, F Mauduit, AP Farrell, D Chabot, H Ollivier… - Aquatic Toxicology, 2017 - Elsevier
We tested the hypothesis that the chronic residual effects of an acute exposure of European
