Collaborative Research: Globec Pan-Regional Synthesis: End-To-End Energy Budgets In Us-Globec Regions, Andrew C. Thomas
University of Maine Office of Research Administration: Grant Reports
The research addresses the overarching question: are marine food webs leading to fisheries controlled from the top-down, the bottom up, or a combination of the two? To address this question we will (1) compare end-to-end energy budgets of the 4 US-GLOBEC study regions in the context of top-down v. bottom-up forcing, (2) assess the skills of the regional models in capturing basic material fluxes, (3) extract diagnostics from the regional models that will be used to evaluate the effects of climate change and fishing pressure across GLOBEC regions and (4) develop quantitative methods to compare the diagnostics. The major successes …

Collaborative Research: The Response Of Lakes To Disturbance And Climate Change: Calibrating Sedimentary Records To Test The Landscape Position Concept, Jasmine E. Saros
University of Maine Office of Research Administration: Grant Reports
Landscape disturbance and climate change affect lakes in proportion to their contact with ground water, sometimes resulting in different responses in neighboring lakes. This project develops methods for reconstructing past water chemistry and food webs of lakes. The biological and chemical deposits in surface sediment samples will be compared with the water in 62 modern lakes. The resulting relationships will be tested by comparing sediment cores with 24 years of observations from the North Temperate Lakes Long Term Ecological Research (NTL-LTER) site. The methods will then be used to reconstruct 150 years of history for several lakes, adding perspective to …
