Colour Polymorphism in Coconut Crabs Is Under Relaxed Selection From Conspecifics?

Ethology, EarlyView.
Coconut crabs are either red or blue irrespective of age or sex, are nocturnal and have very few predators. This experimental study shows that they do not use conspecific's colour but do use relative size to settle competitive interactions over food in the wild.

Factors Influencing the Stocking of Juvenile Pikeperch (Sander lucioperca)

Fisheries 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 ...

Revisiting omnivores in America circa 1990s: The exclusiveness of omnivores?

Poetics, 2008
This study examines the relationship between social status and culture as formulated in Peterson's omnivore–univore thesis. The thesis has often been subjected to empirical investigations using preference or 'likes' data. Analysis of a unique data set (US-General Social Survey 1993) which provides 'likes' as well as 'dislikes' information has shown ...

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, EarlyView.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Linking morpho-taxonomy to ecosystem functions: Trait-based estimation of biomass and potential carbon budget in omnivore nematodes

Ecological Informatics
Omnivore nematodes within the order Dorylaimida are among the largest free-living soil-dwelling nematodes, suggesting a significant role in soil biomass and carbon cycling.

Forest type influence on Heliconia‐dipteran interaction networks

Insect Conservation and Diversity, EarlyView.
Responses to forest type depended on the developmental stage of dipterans. Bract traits and forest type influenced larval abundance, but forest type had no impact on adult alpha and beta diversity. Heliconia‐dipteran interaction networks showed a nested pattern for both forest types.

Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

Journal of Fish Biology, EarlyView.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

Impact of Transition from Natural Grasslands Steppe to Monoculture Artificial Grasslands on Soil Food Webs in the Qinghai–Tibet Plateau

Agronomy
Addressing the imbalance of the livestock–forage–environment system on the Qinghai–Tibet Plateau (QTP), the extensive replacement of natural grasslands with artificial grasslands has been pursued to enhance forage yield and quality.

Resource partitioning among algal turf‐feeding fishes on a tropical artificial shoreline

Journal of Fish Biology, EarlyView.
Abstract Rapid coastal development has led to the proliferation of artificial structures along urban shorelines. Numerous studies have shown that patterns of fish diversity associated with these novel habitats are driven by physical habitat complexity; however, trophic‐mediated processes in shaping these patterns remain poorly understood.
