Environmental selection overwhelmed the geographic 'distance' effect when across biotas, overturning the previously well-accepted geographic pattern for microbes on a large scale.
Integrated phylogenomics and mitochondrial DNA inventory of net-winged beetles across three continents suggest ~1000 undescribed species, biodiversity hot spots, and phylogeny-based classification that sets up the basis for further research.
A consistent pattern of consumption of Triticeae tribe grasses documented in the Danube Gorges of the Balkans since the Early Mesolithic might have facilitated a quick uptake of domesticated cereals due to a developed cultural taste and specific stone tool processing technology.

While predators can clearly reduce mosquito populations by consumption, they can also have non-consumptive effects on mosquito body size and oviposition behavior, and these effects on vector traits can influence infectious disease dynamics.

Ruby-throated hummingbirds switch from using torpor to survive nighttime energy emergencies in the breeding season to using it to spare fat stores and gain premigratory mass in the late summer.

Animals’ tool-handling behaviour can be used to make inferences about the value they ascribe to different tool types, unlocking considerable research potential for observational and experimental studies across diverse species.

Wing transparency in mimetic butterflies and moths is achieved by an unexpected diversity of structural features, and both structures and light transmission properties of wings are under selection for convergence.

Ephemeral leadership between differently experienced birds regulates the balance between exploration and exploitation over successive homing flights in a manner that facilitates the accumulation of route innovations.
