Male-biased dominance in greater bamboo lemurs (Prolemur simus) [PDF]

open access: yesPrimate Biology
Intersexual dominance relationships in virtually all lemur species have been reported to be female-biased. Although a claim of male dominance in greater bamboo lemurs (Prolemur simus) which was not supported by data is unusual against this background, it

Olfactory cue use by three-spined sticklebacks foraging in turbid water: prey detection or prey location? [PDF]

open access: yes, 2012
Foraging, when senses are limited to olfaction, is composed of two distinct stages: the detection of prey and the location of prey. While specialist olfactory foragers are able to locate prey using olfactory cues alone, this may not be the case for ...

Genetic and phenotypic responses to habitat fragmentation in a European harvester ant

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1053-1068, November 2025.
Our work highlights the use of multiple approaches to evaluate species responses to habitat fragmentation. Less allelic richness in habitats with fewer ant nests and reduced heterozygosity with less allelic richness indicated inbreeding; smaller gyne mesosoma size in less connected habitats indicated reduced flight ability.

'Selfish herds' of guppies follow complex movement rules, but not when information is limited [PDF]

open access: yes, 2015
Under the threat of predation, animals can decrease their level of risk by moving towards other individuals to form compact groups. A significant body of theoretical work has proposed multiple movement rules, varying in complexity, which might underlie ...

Dementia prevalence in the Wisconsin Longitudinal Study

open access: yesAlzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION While there is growing appreciation of the importance of sociobiological determinants of dementia, few lifespan cohorts offer well‐characterized dementia outcomes to explore these aims. We sought to identify dementia prevalence in the Wisconsin Longitudinal Study (WLS), one of the most comprehensive lifespan cohort studies in the ...

Neuronal Plasticity in the Mushroom Bodies of Winter Bees Is Retained Despite Substantially Advanced Age

open access: yesDevelopmental Neurobiology, Volume 85, Issue 4, October 2025.
ABSTRACT Honeybee (Apis mellifera) workers exhibit remarkable behavioral plasticity throughout adult life. In spring and summer, they transition through diverse tasks over a short lifespan of 4–6 weeks. This involves dramatic changes in sensory environment and cognitive demands associated with pronounced structural neuronal plasticity in the mushroom ...
