Contrasting population genomic structuring of northern pike (Esox lucius L.) in fresh‐ and brackish water environments: Implications for management and conservation

open access: yesJournal of Fish Biology, Volume 108, Issue 5, Page 1599-1613, May 2026.
Abstract Understanding the factors that shape population genetic structure is crucial for advancing evolutionary studies and developing effective management and conservation strategies. The northern pike (Esox lucius L.) is a top teleost predator that inhabits fresh and brackish water environments in the northern hemisphere.

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

open access: yesIntegrative 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

open access: yesJournal 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 ...
