Doves improve their wingbeat efficacy without elevating maximum pectoralis power by angling their wings mid-downstroke to efficiently generate aerodynamic force while simultaneously tensioning the supracoracoideus tendon to assist the upstroke.

Real-time volatile emission kinetics reveal stress volatiles emitted from herbivore-damaged plants can sequentially prime and induce defense responses in undamaged plants following distinct temporal patterns.
Bird activity during Covid 19 lockdown changed depending on species and site, as well as on environmental parameters and heterospecific (e.g., human) activity, revealing a complex and dynamic urban ecological system.
New archaeobotanical data from Negev Highland rubbish middens demonstrate that crop diversity in the Southern Levant expanded more during the first millennium CE than in any earlier period, yet with minimal consequences for consumption and production patterns.
Microbial macroecological patterns under coarse-graining are captured by a null model of ecology, a result which was leveraged to successfully predict the relationship between fine and coarse-grained diversity.

Alkaloid-binding globulin (ABG) is a novel protein discovered in the plasma of poison frogs that transports many alkaloids, with structural homology to mammalian hormone carriers and amphibian biliverdin-binding serpin.
New immigrants triggered fast uptake of a novel food in groupmates, who obtained information about it through muzzle contacts, opening up new questions about the role of dispersers in information flow around a population.

Characterization of the molecular mechanisms that enable azelaic acid, a secondary metabolite produced by photosynthetic organisms, to promote or inhibit different bacterial populations.
The application of real-time genomics by long-read nanopore sequencing to environmental samples creates a new trajectory for non-invasive genomics-based monitoring of critically endangered wildlife.
