Habitat connectivity for pollinator beetles using surface metrics

摘要: Measuring habitat connectivity in com- plex landscapes is a major focus of landscape ecology and conservation research. Most studies use binary or patch mosaic model for describing spatial heterogeneity understanding pattern-process rela- tionships. While the value gradient approaches proposed by McGarigal Cushman are recognized, applications these newly three dimensional surface metrics remain under-used. We created map quality from several GIS layers applied to measure between 67 locations Indiana, USA surveyed one group ecosystem service providers, flower longicorn beetles (Cerambycidae: Lepturinae). The showed great potential explain differ- ences lepturine assemblages among 2,211 studied (between site pairs). Surface kurtosis its interaction with geographic distance were most important metrics. This approach provided unique information about through four configuration There some uniform trends responses many species metrics, however responded differently other suggest that insight into requirements valuable under- standing dynamics species, guilds, services.
