One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

The brain network associated with social interaction observation involves large part of the frontal cortex and parietal areas in marmosets.

Experimental manipulations and environmental gradients, the two common-used approaches, are not at all comparable for predicting the impacts of climate change on nutrient cycling.

Islands of non-methylated DNA are shown to perform a similar epigenetic role in many different vertebrate species.

PRDM9 is widely conserved across vertebrates yet has been lost numerous times, as has its role in directing meiotic recombination.

Similarities in climatic niches of terrestrial vertebrates indicate the Earth's climate regions, which differ among groups and from previous plant-based climate classifications.

Place cells associated with track-running are activated in rats staying in a nearby box while another rat running on the track, suggesting that social observation facilitates spatial memory representations.

Voluntary movements are preceded by a temporally flexible preparatory neural process that is present regardless of whether movement is initiated rapidly or thoughtfully.

Travel has a major influence on tool use in wild chimpanzees, suggesting that tool use reduced travel costs during hominid evolution.

Citizen science camera trapping showing suburban and wild areas maintain similar levels of mammalian diversity and relative abundance, challenging conventional thoughts about the impacts of urbanization on wildlife.
