Patterns Also Shed Light on How Environmental Disturbances Affect Aquatic Organisms

The ability of deep-sea corals to harbor a broad array of marine life, including commercially important fish species, make these habitat-forming organisms of immediate interest to conservationists, managers, and scientists. Understanding and protecting corals requires knowledge of the historical processes that have shaped their biodiversity and biogeography.

While little is known about these processes, new research described in the journal Molecular Ecology helps elucidate the historical patterns of deep-sea coral migration and gene flow, coincident with oceanic circulation patterns and events. The investigators propose a scenario that could explain the observed evolutionary and present-day patterns in certain coral species. The findings can help scientists determine how climate change and other global processes have affected ocean habitats in the past and how they might do so in the future. (more…)

GAINESVILLE, Fla. — University of Florida researchers received a rare 25-foot-long, deep-water giant squid Monday, the only one of its kind in the collections of the Florida Museum of Natural History.

Recovered by recreational fishermen who found the creature floating on the surface about 12 miles offshore from Jensen Beach Sunday, museum scientists collected the specimen from the Florida Fish and Wildlife Conservation Commission Tequesta Field Laboratory in Palm Beach County and returned to the Gainesville campus late Monday.

*New map of the genetic code of endangered orangutans yields important new conservation tools and insights into evolution*

For the first time, scientists have mapped the genome–the genetic code–of orangutans. This new tool may be used to support efforts to maintain the genetic diversity of captive and wild orangutans. The new map of the orangutan genome may also be used to help improve our understanding of the evolution of primates, including humans.

Partially funded by the National Science Foundation, the orangutan study appears in the Jan. 27 issue of Nature. It was conducted by an international team of scientists led by Devin P. Locke of the Genome Center at Washington University. (more…)
