Investigating the theory of island biogeography in relation to Woodland Islands in the Indiana agricultural landscape using camera trapping methods

Abstract

Habitat fragmentation caused by both urban and agricultural development has led to an increase in habitat “islands” surrounded by a sea of development. In Indiana specifically, woodland habitat islands are surrounded by crop, pasture, and urban lands. This study sought to evaluate if the theory of island biogeography also applies to this landscape. Specifically, this study investigated whether species richness varies based on island area and relative isolation. This was accomplished using camera traps with a targeted, non-random sampling approach to achieve maximum species observability. Results indicate that the theory is not applicable to this scenario based on area and relative isolation. This may be important to note for future management decisions.
