Does a lack of juveniles indicate a threat? Understanding body size distributions in a group of long‐lived vertebrates

Journal of Animal Ecology, Volume 94, Issue 10, Page 1962-1982, October 2025.
We used a large dataset to examine turtle size distributions and found that for most species in most areas, distributions are typically skewed towards large adults, with few juveniles present. Therefore, a lack of juveniles does not inherently indicate a declining population, and researchers should be cautious not to over‐interpret adult‐dominated ...

Effects of autotomy compared to manual declawing on contests between males for females in the edible crab, Cancer pagurus: implications for fishery practice and animal welfare. [PDF]

, 2016
In many decapod fisheries, claws are removed and the animal returned to the sea with the assumption that there is little impact on the fitness and welfare of the animal, or onthe productivity of the population.

Hydrology drives facilitative and competitive strategies in freshwater macrophyte and microbial communities

Ecosphere, Volume 16, Issue 9, September 2025.
Abstract Pulses of resource availability along environmental gradients can filter the local and regional distribution of macrophyte and microbial mat communities in wetlands. Wetlands that experience short hydroperiods (i.e., <6 months with standing water) may cause macrophyte and microbial mat competition for water.

Fiddler crabs from highly disturbed beaches are more sensitive to human presence [PDF]

Anais da Academia Brasileira de Ciências
The presence of humans frequently modifies the behavior of animals, particularly their foraging patterns, compromising energetic demands. The fiddler crab Leptuca leptodactyla inhabits mangroves with high degrees of anthropogenic influence.

Courtship herding in the fiddler crab Uca elegans

Journal of Comparative Physiology A, 2008
Male and female animals are not always complicit during reproduction, giving rise to coercion. One example of a system that is assumed to involve sexual coercion is the mate herding behaviour of fiddler crabs: males push females towards the home burrow with the goal of forcing copulation at the burrow entrance.

Links Between Child Executive Function and Adjustment: A Three‐Site Study

Child Development, Volume 96, Issue 5, Page 1590-1604, September/October 2025.
ABSTRACT Cross‐site comparisons indicate that East Asian children typically excel on tests of executive function (EF), but interpreting this contrast is made difficult by both the heavy reliance on testing in school settings and by the scarcity of studies that assess across‐site measurement invariance.

Density-dependent effect on reproductive behaviour of Lysmata amboinensis and L. boggessi (Decapoda: Caridea: Hippolytidae) [PDF]

, 2007
We compared the reproductive behaviours of two protandric simultaneous hermaphroditic species (Lysmata amboinensis and L. boggessi) that belong to two groups of Lysmata shrimp with different morphology, geographical distribution, and density.

The evolutionary biology of dance without frills [PDF]

, 2016
Recently psychologists have taken up the question of whether dance is reliant on unique human adaptations, or whether it is rooted in neural and cognitive mechanisms shared with other species 1, 2. In its full cultural complexity, human dance clearly has

Hydrological repair and invasive grass removal restore Rhizophora racemosa mangrove communities in West Africa

Restoration Ecology, Volume 33, Issue 7, September 2025.
Mangrove ecosystems face significant threats from climate change and human activities. In West Benin, the invasive grass Paspalum vaginatum disrupts sedimentation and hydrology, creating anoxic conditions and nutrient imbalances. To address this, we implemented a cost‐effective restoration strategy focused on hydrological repair, engaging local ...
