Fertility of a spontaneous hexaploid male Siberian sturgeon, Acipenser baerii. [PDF]

BMC Genet, 2014
Evolution of sturgeons and paddlefishes (order Acipenseriformes) is inherently connected with polyploidization events which resulted in differentiation of ploidy levels and chromosome numbers of present acipenseriform species. Moreover, allopolyploidization as well as autopolyploidization seems to be an ongoing process in these fishes and individuals ...

Mechanism of Ammonia‐Induced Brain Damage in Chinese Striped‐Necked Turtle (Mauremys sinensis)

Integrative Zoology, Volume 21, Issue 2, Page 421-434, March 2026.
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.

Warm and cool temperatures decrease early‐life telomere length in wild pied flycatchers

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
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 ...

Integrated Use of Oxidative Stress and Histological Biomarkers of T. tinca as Indicators of 17‐Alpha‐Ethynylestradiol Exposure

Environmental Toxicology, Volume 41, Issue 1, Page 49-67, January 2026.
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 ...

Early Nutritional Programing: Unlocking the Potential of Fish for Sustainable Aquaculture

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Nutritional programing, which explores the link between early nutritional conditions and their long‐term effects on animals, is a developing field within fish biology. Suboptimal nutritional status during early life is strongly associated with a higher risk of metabolic consequences later in life, including permanent growth retardation, impaired neural

First description of Siberian sturgeon herpesvirus-induced mortality in Russian sturgeon (Acipenser gueldenstaedtii) and in Siberian sturgeon (Acipenser baerii) in Hungary: An emerging pathogen in aquaculture

Acta Veterinaria Hungarica
Abstract Acipenserid species play an important role in aquaculture. Emerging viral diseases can cause high mortality on farms. During our investigations, Siberian sturgeon herpesvirus (SbSHV) was detected on a fish farm in Hungary rearing Russian sturgeon ( Acipenser gueldenstaedtii
