Data used for application in paper Mechanistic modeling of climate effects on redistribution and population growth in a community of fish species. Abstract:

Understanding community responses to climate is critical for anticipating the future impacts of global change. However, despite increased research efforts in this field, models that explicitly include important biological mechanisms are lacking. Quantifying the potential impacts of climate change on species is complicated by the fact that the effects of climate variation may manifest at several points in the biological process. To this end, we extend a dynamic mechanistic model that combines population dynamics, such as species interactions, with species redistribution by allowing climate to affect both processes. We investigate their relative contributions to the changing biomass of a community of eight species in the Gulf of Maine. Using over 30 years of fisheries data from the Northeast Fishery Science Center, we find that the mechanisms driving biomass trends vary across space, time, and species.
