A jumping spider discriminates familiar from novel conspecifics for hours, indicating recognition and long-term memory in a miniature-brained, asocial arthropod, highlighting learning and internal representations in small nervous systems.
Early-life environment shapes how wild bats behave as adults, showing that developmental experience, rather than innate predisposition, drives individual differences in foraging behavior.
The uplift of the Qinghai-Tibet Plateau redirected avian migrations from latitudinal to longitudinal paths through induced monsoon systems, fundamentally reshaping continental biogeographic patterns.
A model of a species-rich neutral ecosystem, perturbed by environmental noise impacting each species differently, predicts that for large noise the community is dominated by a few species, while for weaker noise it is more egalitarian, with many significant species.
