The seasonality and diversity of members of the beetle family Leiodidae were determined for an old-growth and a 40-yr-old forest. Thirty-four species were found at each site for a combined total of 39 species. Seasonality is lengthily unimodal for the Cholevinae, which feed on carrion and fungi. Leiodinae feed on slime molds and fungi and are more narrowly unimodal. Anisotoma spp. exhibit broadly overlapping abundance peaks, whereas some members of Agathidium and Leiodes have abundance peaks at different times, indicating the possibility of resource partitioning. The greater leaf litter depths and amount of woody debris at the old-growth site lead to the production of more food resources for leiodids. The difference in forest ages and the disturbance by selective cutting has not lowered species richness, but diversity indices reflect a difference between the sites based on greater abundance in the old-growth forest. Anisotoma inops is a potential indicator species for old-growth forests in NE North America. -from Authors
