Convergent evolution of plant prickles is drivenby repeated gene co-option over deep time

The paper investigates convergent evolution of plant prickles, finding that mutations in a cytokinin gene repeatedly cause prickle loss across species.

Translational T-box riboswitches bind tRNA by modulating conformational flexibility

This study uses single-molecule FRET to analyze the binding mechanism of the Mycobacterium tuberculosis IleS T-box riboswitch, revealing a two-step model and the role of specific sequences in conformational flexibility and tRNA recognition.

Andes virus genome mutations that are likely associated with animal-model attenuation and human person-to-person transmission

The paper identifies genome mutations in Andes virus associated with attenuation in animal models and increased human transmissibility.

Jaccard dissimilarity in stochastic community models based on the species-independence assumption

The paper develops probabilistic models to analyze beta-diversity by considering species presence probabilities across sites and applies them to woodpecker distribution data.

The Implicit Assumptions of Classic Functional Responses and their Multi-Species Extensions

This paper re-examines the assumptions behind classic functional responses and introduces a new predator-dependent form when consumer interference is considered.

Wild common crossbills produce redder body feathers when their wings are clipped

The paper shows that clipped-wing male common crossbills develop redder rump feathers than controls, suggesting flight metabolism affects carotenoid conversion to red pigments.

Emerging Hantaviruses in Central Argentina: first case of Hantavirus Pulmonary Syndrome caused by Alto Paraguay Virus and a novel orthohantavirus in Scapteromys aquaticus rodent.

A signal of competitive dominance in mid-latitude herbaceous plant communities

The paper analyzes plant distribution and trait data across Europe to show that plant height clustering relates to evapotranspiration and gross primary productivity, indicating interspecies competition in mid-latitude regions.

A mitochondria-targeted antioxidant affects the carotenoid-based plumage of red crossbills

The study shows that mitochondria-targeted antioxidants affect carotenoid-based plumage coloration in red crossbills, with effects dependent on initial plumage redness.
