There is increasing evidence that habitat decline via fragmentation or species loss can lead to of cultural diversity, complexity richness in non-human animals. For example, a reduction local bird leads lyrebirds sing fewer complex songs, while great apes living fragmented landscapes have smaller repertoires. However, the link between animal culture and ecology remains understudied, potentially interactions ongoing ecological change are poorly understood. Here, we review current state knowledge on how influences culture, focusing vocal communication foraging behaviour. We identify key factors affecting patterning, including direct effects (e.g. environmental variability) indirect connectivity). then emerging for identifying three major threatening processes: fragmentation, degradation urbanization. Finally, develop predictive framework effect these processes highlight diversity fitness costs with conservation implications.This article part theme issue 'Animal culture: changing world'.

The rapid conversion of natural habitats to anthropogenic landscapes is threatening insect pollinators worldwide, raising concern regarding the negative consequences on their fundamental role as plant pollinators. However, not all are negatively affected by habitat conversion, certain species find appropriate resources in persist and proliferate. reason why some tolerate environments while most them inhospitable remains poorly understood. cognitive buffer hypothesis, widely supported vertebrates but untested insects, offers a potential explanation. This theory suggests that with larger brains have enhanced behavioural plasticity, enabling confront adapt novel challenges. To investigate this hypothesis we measured brain size for 89 bee species, evaluated association degree occupancy. Our analyses revealed mainly found urban had relative body than those tend occur forested or agricultural habitats. Additionally, bees exhibited sizes and, consequently, absolute sizes. results provide first empirical support invertebrates, suggesting large could confer advantages environments.

Brain size tripled in the human lineage over four million years, but why this occurred remains uncertain. Here, to study what caused brain expansion, I mathematically model evolutionary and developmental (evo-devo) dynamics of hominin size. The recovers (1) evolution body sizes seven species starting from australopithecine scale, (2) brain-body allometry (3) major patterns development evolution. show that expansion recovered is not by direct selection for its genetic correlation with developmentally late preovulatory ovarian follicles. This generated if individuals experience a challenging ecology seemingly cumulative culture, among other conditions. These findings exceptionally adaptive traits may be primarily them constraints divert selection.
