Habitats of satellite-tracked blue sharks were shifted surfaceward by an oxygen minimum zone (OMZ) at depth thereby increasing their susceptibility to capture by longline fishing focused above the OMZ.
The gustatory receptor PxylGr34 is tuned to the steroid plant hormone brassinolide and mediates the deterrent effects of brassinolide on feeding and ovipositing behaviors in Plutella xylostella.
Microbiomediversity favors further diversity in a positive feedback that is strongest in lower-diversity biomes but which plateaus as niches are increasingly filled in higher-diversity biomes.
Integration of automatic behavioral tracking with brain molecular profiling reveals the role of gene regulatory network plasticity in the regulation of behavioral phenotypes.

Migratory birds with fuel stores composed of more omega-6 fats saved energy during long-duration flights, but this short-term energy saving came at the long-term cost of higher oxidative damage.
The likelihood to perform tool use during foraging is linked to personality traits in ants, suggesting an original interplay between consistent inter-individual variability and division of labor in social species.
Patterns of antibiotic use and the connectivity between wards are independently associated with the incidence of antimicrobial-resistant infections in hospital networks.
Moving patients between wards and prescribing high levels of antibiotics increases the spread of bacterial infections that are resistant to treatment in hospitals.
