Population dynamics are a prominent emergent property of biological systems. We study spatiotemporal variation in the abundance of forest insects, including those that can be “pests”. Our research questions include: (1) why are some populations stable in space and time while others fluctuate greatly; (2) what are the causes and consequences of spatial patterning in population fluctuations; (3) how do demographic processes operating at different spatial scales interact to influence landscape patterns in abundance; (4) how do community interactions and abiotic factors combine to influence animal population dynamics; and (5) how, if at all, does climate change influence forest animals. Current projects at Hubbard Brook include: effects of nutrient availability to trees on animals that eat trees (chiefly caterpillars) and the animals that eat them (chiefly birds and wasps); effects of variable phenology (e.g., timing of leaf-out in spring) on species interactions and food webs; effects of the incipient elimination of ash trees from forests on biodiversity, food webs, and ecosystem processes.
