Project Troff document Tampa Bay Seagrass Transplanting Project
This project is a seagrass transplanting project within Tampa Bay, Florida.
Located in Resources / Whitewater to Bluewater W2B
Project chemical/x-pdb Improving Management of Seagrass Resources through Restoration and Assessment
Lead by the Environmental Protection Commission of Hillsborough City, this project will manage seagrass beds through creating a poll n troll zone to reduce seabed scaring, as well as testing different grass restore methods.

File PDF document Experimental climate change weakens the insurance effect of biodiversity
Ecosystems are simultaneously affected by biodiversity loss and climate change, but we know little about how these factors interact. We predicted that climate warming and CO2-enrichment should strengthen trophic cascades by reducing the relative efficiency of predation-resistant herbivores, if herbivore consumption rate trades off with predation resistance. This weakens the insurance effect of herbivore diversity. We tested this prediction using experimental ocean warming and acidification in seagrass mesocosms. Metaanalyses of published experiments first indicated that consumption rate trades off with predation resistance. The experiment then showed that three common herbivores together controlled macroalgae and facilitated seagrass dominance, regardless of climate change. When the predation-vulnerable herbivore was excluded in normal conditions, the two resistant herbivores maintained top-down control. Under warming, however, increased algal growth outstripped control by herbivores and the system became algal-dominated. Consequently, climate change can reduce the relative efficiency of resistant herbivores and weaken the insurance effect of biodiversity.

File PDF document Editorial : Beyond forest carbon
The preservation of forests, both on land and in mangrove swamps, has received much attention in the move to protect biological carbon stores. Less conspicuous communities of organisms deserve some scrutiny, too.

File Contrasting futures for ocean and society from different anthropogenic CO2 emissions scenarios
The ocean moderates anthropogenic climate change at the cost of profound alterations of its physics, chemistry, ecology, and services. Here, we evaluate and compare the risks of impacts on marine and coastal ecosystems—and the goods and services they provide—for growing cumulative carbon emissions under two contrasting emissions scenarios. The current emissions trajectory would rapidly and significantly alter many ecosystems and the associated services on which humans heavily depend. A reduced emissions scenario — consistent with the Copenhagen Accord’s goal of a global temperature increase of less than 2°C — is much more favorable to the ocean but still substantially alters important marine ecosystems and associated goods and services. The management options to address ocean impacts narrow as the ocean warms and acidifies.
