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.
In the fruit fly Drosophila melanogaster, stem cell activity ages female guts but not male guts; furthermore, males with feminized guts develop pathologies but gain an increase in lifespan through dietary restriction.
Heme accumulation is toxic, but deficiency of the heme transporter HRG1/SLC48A1 causes heme sequestration and crystallization into hemozoin within enlarged lysosomes of macrophages, thereby conferring heme tolerance to mammals.
The optimal macronutrient composition, macronutrient space, varies strongly between closely related species and is determined by genetic changes in regulatory genes that globally reprogram gene expression profiles of metabolic pathways.
A systematic experimental comparison of prosocial behavior in eight corvid species reveals sex-specific effects of cooperative breeding and colonial nesting, thereby adding important new insights regarding the evolution of prosociality.
Microbiome and transcriptomic profiling of genetically selected tropical fish with high and low tolerance to cold exposure revealed host control over microbiome composition and response to temperature changes.
