Flower color polymorphism in the peacock anemone (Anemone pavonina) reflects spatiotemporal variation in pollinator abundance. [PDF]
Am J BotAbstract Premise Flower color polymorphisms are found across angiosperms and are shaped by multiple environmental factors. We investigated Anemone pavonina, which displays flower color variation from red to purple along an elevational gradient on Mount Olympus, Greece.

Robustness of the honeybee neuro-muscular octopaminergic system in the face of cold stress
Frontiers in Physiology, 2022 In recent decades, our planet has undergone dramatic environmental changes resulting in the loss of numerous species. This contrasts with species that can adapt quickly to rapidly changing ambient conditions, which require physiological plasticity and ...

The lemur baseline: how lemurs compare to monkeys and apes in the Primate Cognition Test Battery [PDF]
PeerJ, 2020 Primates have relatively larger brains than other mammals even though brain tissue is energetically costly. Comparative studies of variation in cognitive skills allow testing of evolutionary hypotheses addressing socioecological factors driving the ...

Sex-specific movement ecology of the shortest-lived tetrapod during the mating season
Scientific Reports, 2022 Sex-specific reproductive strategies are shaped by the distribution of potential mates in space and time. Labord’s chameleon (Furcifer labordi) from southwestern Madagascar is the shortest-lived tetrapod whose life-time mating opportunities are ...

Sex differences in audience effects on anogenital scent marking in the red-fronted lemur
Scientific Reports, 2022 How the presence of conspecifics affects scent mark deposition remains an understudied aspect of olfactory communication, even though scent marking occurs in different social contexts.

Reproductive Senescence in Two Lemur Lineages
Frontiers in Ecology and Evolution, 2022 The relationship between age and reproductive performance is highly variable across species. Humans and some cetaceans exhibit an extreme form of reproductive senescence in that female reproduction ceases years or even decades before average life ...

The ant’s weapon improves honey bee learning performance
Scientific Reports, 2023 Formic acid is the main component of the ant’s major weapon against enemies. Being mainly used as a chemical defense, the acid is also exploited for recruitment and trail marking. The repelling effect of the organic acid is used by some mammals and birds

The sociobiology of biofilms [PDF]
FEMS Microbiology Reviews, 2009 Biofilms are densely packed communities of microbial cells that grow on surfaces and surround themselves with secreted polymers. Many bacterial species form biofilms, and their study has revealed them to be complex and diverse. The structural and physiological complexity of biofilms has led to the idea that they are coordinated and cooperative groups ...
