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…)

Majority of Egyptians Faults Brotherhood Fielding its Own Candidate

COLLEGE PARK, Md. – As Egypt prepares this week to elect its first president since the 2011 revolution, a new University of Maryland poll finds the Muslim Brotherhood’s candidate tied for fourth place. Researchers describe the race as fluid.

The poll confirms the strategic damage inflicted by the Brotherhood’s decision to field its own candidate, after saying it would not. Nearly three-quarters of those surveyed (71 percent) called the decision a “mistake.”

The poll also shows Egyptians approaching the race differently from Parliamentary elections, focusing more on personal trust and the economy over party affiliation. (more…)
