A new acoustic telemetry tag that identifies carrier mortality by monitoring activity level

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1735-1742, June 2026.
Abstract We present a new acoustic telemetry tag capable of detecting whether its carrier stops moving for long enough to presume the organism has died, and of reporting the time elapsed since movement ceased. The tag uses existing environmental sensor technology together with an algorithm with user‐specifiable thresholds, and importantly, can separate

Relationships Between European Wildcats and Domestic Cats in an Area of Sympatry: Exploring Key Conservation Questions on Hybridization and Disease Transmission

Animal Conservation, Volume 29, Issue 3, Page 321-333, June 2026.
We have found evidence of behavioural barriers for both hybridization and disease transmission between European wildcats and domestic cats. This includes hierarchical interspecies exclusion enforced by wildcats, as well as sexual selection exerted by wildcat females.

In Search of the Lost Brown Trout (Salmo trutta Complex) Using DNA of Ancient and Modern Samples From the Southern Italian Peninsula

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT The current diversity and distribution of species and populations have been shaped by the major climatic oscillations during the Quaternary. The brown trout (Salmo trutta) is a striking example of the strong effect of past climate changes on the evolutionary history of species, in fact, the alternation of glacial/interglacial cycles has led to

Farmed Escapees Threaten MHC Diversity in Wild Atlantic Salmon

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Wild Atlantic salmon populations in Norway and elsewhere are experiencing long‐term declines driven by reduced marine survival, climate change, impacts from aquaculture, introduction of alien species, and environmental degradation. Understanding how immune diversity is affected by these declines, and thus the ability of Atlantic salmon to ...

Factors Influencing the Stocking of Juvenile Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, Volume 33, Issue 3, Page 425-437, June 2026.
ABSTRACT Predator species of fish play crucial roles in ecosystem balance through top‐down control, a mechanism frequently exploited in biomanipulation to stock predator species. Juvenile pikeperch (Sander lucioperca) were stocked (n = 52,887) in spring 2023 and 2024 and autumn 2023 to compare stocking efficiency between Recirculation Aquaculture ...

Photoperiod modulates male sexual maturation in the Emperor tetra (Nematobrycon palmeri), a strictly tropical ornamental fish

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Photoperiod manipulation is widely used to regulate reproduction in temperate fish species, but little is known about its effects in strictly tropical species. This study evaluated whether the Emperor tetra (Nematobrycon palmeri), a tropical ornamental fish, can modulate sexual maturation in response to artificial light regimes.
