Now, rapid*environmental change from local to global scales, accompanied by biodiversity gains and losses, impart a sense of*urgency to this question. This proposal outlines a plan to answer the questions:*How do temperature change and biodiversity change affect ecosystem adaptive*capacity? My research team will answer this question through a series of*experiments and*syntheses to test hypotheses and advance theory. The specific objectives of*this proposal are 1) to extend my research on metabolic scaling of population*and community processes to an Ecosystem*Adaptive Capacity (EAC)*framework by conducting experiments and critical tests in aquatic communities,*2) to extend my BEF research to determine the role of spatial processes in*sustaining EAC in warming environments, and 3) to apply the EAC framework to*seagrass ecosystems to develop approaches for identifying conservation*priorities in changing seascapes.***The*research plan extends an EAC framework to include effects of warming on basic*biological processes present in all ecosystems, and to then determine how these*biological processes might depend on biodiversity processes in landscapes. To*build this framework, we will conduct eight experiments in freshwater and*coastal marine ecosystems, explicitly testing how temperature and biodiversity change interact to determine ecosystem functions in a changing environment and along human impact gradients. The research will involve*cross-disciplinary collaboration among labs at UBC, and advanced skill*development and career networking for undergraduate, graduate and postdoctoral*trainees. Trainees can leave this project competitive for jobs in academia,*education, government science or positions requiring knowledge of mitigation*options for ecological effects of climate change in Canada.***The projects span multiple*scales of organization - from genes*to ecosystems. The mathematical frameworks used to design and interpret*the careful experimental tests will allow us to apply the framework more broadly to understand environmental change in coastal biodiversity in seagrass ecosystems. This valuable ecosystem is*vulnerable to climate change and destruction by shoreline development. We aim to produce decision-relevant science to help find conservation solutions that maximize ecosystem adaptive capacity*along Canadian coastlines.
