Temporal scope influences ecosystem driver-response relationships: A case study of Lake Erie with implications for ecosystem-based management

Former AELers Mike Fraker and James Sinclair along with AEL faculty Jim Hood and Stu Ludsin as well as long-time collaborator Ken Frank take a long-term (1969-2018) look at the driver-response relationships in Lake Erie. For this work, they compiled a large dataset of multiple biological, physical, chemical, and socioeconomic components to quantify trends and identify potential key drivers during multiple time intervals.

Nutrient enrichment intensifies the effects of warming on metabolic balance of stream ecosystems

Jim Hood and colleagues show that nutrient enrichment drove large reductions in net ecosystem production, and interactions with temperature amplified these effects in warm N-enriched streams. These responses were shown to be driven by increase respiration of microbial heterotrophs.

Our study provides direct experimental evidence that warming-induced increases in CO2 emissions to the atmosphere are likely intensified in stream ecosystems subject to eutrophication.
