Why we age

Biological Reviews, Volume 101, Issue 2, Page 911-925, April 2026.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Bioactivity Profiling of Coronarin A and Villosin Isolated From Hedychium coronarium J. Koenig: Acaricidal, Nematicidal, and Antifungal Potential

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
The graphical abstract illustrates the flowchart for the isolation and evaluation of bioactive compounds from Hedychium coronarium. Crude extracts were obtained via cold percolation from the aerial parts (flowers, leaves, and stems) using dichloromethane (DCM) and from the rhizomes using chloroform.

Fecal Material of Captive Wild Animals as Source of CAZymes With Application Potential

ChemBioChem, Volume 27, Issue 8, April 2026.
With the goal to identify a novel resource of enzymes, we tested for the potential of fecal metagenomes of captive wild animals to provide CAZymes. Our data show that CAZymes profiles differed between animals with varying gut physiology and diet, and that metagenomes of captive wild animals can be considered source of diverse CAZymes including rare and

Living at the Interface: Behavioral, Evolutionary and Ecological Insights of Spring Use by Highly Mobile Stygobiont Crustaceans, Troglocaris planinensis (Decapoda: Atyidae)

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The study provides evidence that animals considered as strictly linked to subterranean habitats can exhibit behavioral responses to constraints occurring in surface environments. We studied the blind and depigmented shrimp Troglocaris planinensis in the Classical Karst using field and experimental approaches.

Are Toxic Butterflies More Easily Detected by Human ‘Predators’?

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Aposematic signals are often thought to be conspicuous and stable across environments. Yet, butterflies can have distinct colours on their dorsal and ventral sides which contradict this prediction. We found that despite toxic butterflies having similar detectability on both sides, only dorsal detectability positively correlated with toxicity.
