Adaptations by the locomotor systems of terrestrial and amphibious crabs walking freely on land and underwater

, 2004
What are the mechanisms underlying adaptation to load by locomotor systems? Amphibious shore crabs (Carcinus maenas) must routinely accommodate large load changes as they move in and out of water, where buoyancy supports a large percentage of their ...

Beyond Extrafloral Nectaries: Plant Traits as Drivers of Spider Occurrence in the Cerrado

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Patterns of predator occurrence arise from a mosaic of plant‐derived cues, yet most studies address these traits in isolation. Although extrafloral nectaries have received considerable attention, we lack a comprehensive view of how multiple plant traits jointly affect the diversity and abundance of spiders.

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Decoration behaviour in a spider crab, acanthonyx scutiformis (dana, 1851) in relation to life stage, sex and algal species

, 2016
In this study we evaluated the types of algae chosen for decorating by the spider crab Acanthonyx scutiformis (Dana, 1851) and determined whether decorating is more common in juvenile or adult crabs and in females or males (adult).

On the morphological differentiation between Libinia spinosa and L. ferreirae (Crustacea: Brachyura: Majoidea: Epialtidae)

Zoologia (Curitiba), 2012
Libinia spinosa H. Milne Edwards in Guérin, 1832 and L. ferreirae Brito Capello, 1871, inhabit very similar environments, and their geographic and bathymetric distributions overlap for about 3000 km along the southwestern Atlantic.
