Horned passalus (Odontotaenius disjunctus) distribution at multiple scales

The study of species in their spatial, environmental, and community context is the goal of metacommunity studies. Wood-boring insects provide a useful study system for these studies because of their discrete habitat at both log and forest levels. The distribution of the passalid beetle Odontotaenius disjunctus at multiple scales was surveyed in the bottomland hardwood forests of the Mississippi alluvial floodplain in Louisiana. Within-log, within-site, and among-site distributions are considered. At each level, the relative influence of spatial patterns, habitat characteristics and wood-boring insect community composition are considered.
