From: Wild bee distribution near forested landscapes is dependent on successional state
Species abundance (a) and richness (b) of wild bees at different distances from the forest margin separated by nesting behavior. Ground nesting species were more abundant and diverse at distances further from forest margins. Stem nesting species were most abundant closest to forest margins. (*) denote overall significance of ground nesters over stem while letters (a–d) denote differences of either nesting biology at each distance
