Background:Forested landscapes are valuable sources of ecosystem services especially in areas dedicated to intense agricultural *** from forest margin is known to influence the wild bee community in the landscape surrounding forested *** little is known regarding how bee communities distribute themselves in landscapes that exhibit different forest successional ***:We examined how land use type and distance from the forest edge affect the abundance and richness of the wild bee community across four forest successional *** were collected in sites representing four stages of forest succession and analyzed using generalized linear mixed models with negative binomial ***:wild bee diversity is reduced in forested environments that maintain dense stands of trees and high canopy ***,distance from the forest edge was an important factor determining wild bee distribution in successional stages adjacent to forest ***,we found that bees maintain high specificity for distinct successional states and ***:Our results demonstrate how different successional stages can harbor different bee species and highlight the ability of microhabitats to act as reservoirs of bee diversity in and around forest ***,we found that maximizing successional patchiness across forested landscapes increases the amount of available habitat that can support a diverse suite of bees with different nesting biologies and behaviors.
