Discriminative Reactions to Behaviour and Social Attributes of Non‐Mother Individuals in Wild Infant Japanese Macaques on Yakushima (Macaca fuscata yakui)

open access: yesEthology, EarlyView.
Overview of the study. ABSTRACT Mammalian infants exhibit context‐dependent behavioural reactions in social interactions. Despite extensive research on these discriminative reactions, studies have lacked diversity in infant behaviours and have reported inconsistent findings.

Mechanisms of Body Alignment in a Diurnal Songbird Migrant

open access: yesEthology, EarlyView.
The graphical abstract illustrates the body alignment mechanism of a diurnal songbird migrant, the dunnock (Prunella modularis). Dunnocks consistently expressed an angular body alignment, with inter‐individual variation at the level of the population.

A Meta‐Analysis on Environmental Triggers of Spawning Migrations Reveals a New Classification of Thermal Guilds in European Freshwater Fishes

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Fish migration through river networks is essential for completing life cycles and accessing critical habitats, but fragmentation increasingly disrupts spawning movements. In Europe, over one million barriers limit connectivity and create trade‐offs between ecological integrity and human uses, such as hydropower, flood control, fisheries and ...

Factors Influencing the Stocking of Juvenile Pikeperch (Sander lucioperca)

open access: yesFisheries Management and Ecology, EarlyView.
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 ...

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.
