Tracking Fish Through a Coral Reef Seascape

Ear-bone ‘tree rings’ provide evidence of connectivity

Ocean scientists have long known that juvenile coral reef fishes use coastal seagrass and mangrove habitats as nurseries, later moving as adults onto coral reefs. But the fishes’ movements, and the connections between different tropical habitats, are much more complex than previously realized, according to a study published September 3 in Proceedings of the National Academy of Sciences. The findings have important implications for management and protection of coral reefs and other marine environments.

A number of studies have demonstrated a strong relationship between the presence of coastal wetlands and offshore fish abundance and fisheries yield, but it has proved difficult to develop quantitative assessment of habitat use by fish or their movement among different habitats. “The rationale for this study,”says Simon Thorrold, a biologist at Woods Hole Oceanographic Institution (WHOI), “was to determine the relative importance of different nursery habitats to reef fishes that spend their adult lives on coral reefs but may spend at least part of their juvenile residency elsewhere.” (more…)

Canadians More Likely to Support Policies to Address Climate Change Than Americans

ANN ARBOR, Mich.— Americans are less willing to open their wallets to pay for increased production of renewable energy resources than Canadians, a new University of Michigan report indicates.

Americans who indicated they would not pay anything each year was at 41 percent compared with 21 percent for their counterpart. The willingness of Americans to contribute anything has declined between 2008 and 2010, the report said.

“Canadians are far more likely to see climate change as real and as a serious problem, and this appears to translate into greater willingness to take concrete steps in response,” said Barry Rabe, Arthur Thurnau Professor of the Gerald R. Ford School of Public Policy, and one of the report’s authors. (more…)
