FOREST PRODUCTIVITY PREDICTS INVERTEBRATE BIOMASS ANDOVENBIRD (SEIURUS AUROCAPILLUS) REPRODUCTION INAPPALACHIAN LANDSCAPES

Ovenbird (Seiurus aurocapilla) Science Article 1

abstract

Forest-floor detrital food webs are sustained by annual inputs of leaf fall.However, it is unknown whether this bottom-up effect extends to vertebrates feeding onthe detrital food web. We hypothesized that reproductive success of Ovenbirds (Seiurusaurocapillus L.) is a function of macroinvertebrate biomass within the detrital food web,and that both macroinvertebrate biomass and Ovenbird reproduction can be predicted fromforest productivity (measured by site index)
