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.

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
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)
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 ...

ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

ABSTRACT Host–parasite interactions are influenced by both abiotic and biotic factors. While abiotic drivers, particularly temperature, have received considerable attention in recent years due to global climate change, the role of biotic factors remains comparatively underexplored.

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.

Abstract Cholecystokinin receptor (CCKR), an important recognition receptor for the gastrointestinal hormone cholecystokinin (CCK) in the endocrine system, plays a crucial role in regulating immune responses in mammals. In this study, a novel cholecystokinin receptor (CiCCKR) was identified from the grass carp Ctenopharyngodon idella.
