Circulating Rhythmic Metabolites and Causal Risk of Type 2 Diabetes in Adults in the Canadian Longitudinal Study on Aging

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 5, Page 4243-4252, May 2026.
ABSTRACT Aims Circadian regulation of metabolism is an important factor in metabolic health, yet the role of rhythmic metabolites in Type 2 diabetes development remains poorly understood. This study investigated associations between circulating rhythmic metabolites and incident Type 2 diabetes risk and evaluated causal relationships using two‐sample ...

When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

open access: yesEthology, Volume 132, Issue 5, Page 305-316, May 2026.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

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

open access: yesEthology, Volume 132, Issue 5, Page 359-364, May 2026.
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.
