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 ...

Mechanism of Ammonia‐Induced Brain Damage in Chinese Striped‐Necked Turtle (Mauremys sinensis)
High levels of ammonia disrupt the integrity of the brain barrier in Mauremys sinensis, leading to tissue edema. This, in turn, triggers a series of cascade reactions, including disturbances in neurotransmitter levels, particularly glutamate, which might further exacerbate the neurotoxic effects.

Mechanical shock during egg de-adhesion and post-ovulatory ageing contribute to spontaneous autopolyploidy in white sturgeon culture (Acipenser transmontanus) [PDF]
Spontaneous autopolyploidy, a 1.5x increase in genome size resulting from second polar body retention after fertilization, has been documented in cultured sturgeons, with the proportion of spontaneous autopolyploid progeny ranging widely among maternal ...

Warm and cool temperatures decrease early‐life telomere length in wild pied flycatchers
Climate change represents a major challenge for avian species. It is characterized by an increase in average ambient temperatures, but also by an increase of extreme weather events, such as heatwaves and cold snaps. These abrupt temperature changes can modify the immediate and long‐term survival prospects of nestling birds, when their thermoregulatory ...

Shyer fish are superior swimmers in Siberian sturgeon (Acipenser baerii)
Differences in individual personality are common amongst animals, which can play an ecological and evolutionary role given links to fitness. Personality affects animal life processes and outputs (e.g., behavior, life history, growth, survival ...

ABSTRACT The potential adverse effects of 17‐alpha‐ethynylestradiol (50, 100, and 500 μg EE2/kg b.w., for 30 days) on tench ( Tinca tinca ) were evaluated by integrating biomarkers including physiological (hepato‐somatic index, spleen‐somatic index, and hematocrit), oxidative stress (catalase, glutathione peroxidase, and glutathione reductase ...
