– In Order to Save Biodiversity, Society’s Behavior Must Change, Leading Conservationists Warn

ScienceDaily (Sep. 9, 2010) — An innovative grouping of conservation scientists and practitioners have come together to advocate a fundamental shift in the way we view biodiversity. In their paper, which was published September 9 in the journal Science, they argue that unless people recognise the link between their consumption choices and biodiversity loss, the diversity of life on Earth will continue to decline.

– New Model Provides More Effective Basis for Biodiversity Conservation

ScienceDaily (Sep. 12, 2010) — A mathematical model that provides a more effective basis for biodiversity conservation than existing frameworks has been developed by a researcher at the Hebrew University of Jerusalem.

– Flying Fish Glide as Well as Birds, Researchers Find

ScienceDaily (Sep. 11, 2010) — We’re all familiar with birds that are as comfortable diving as they are flying but only one family of fish has made the reverse journey. Flying fish can remain airborne for over 40s, covering distances of up to 400m at speeds of 70km/h. Haecheon Choi, a mechanical engineer from Seoul National University, Korea, became fascinated by flying fish when reading a science book to his children. Realising that flying fish really do fly, he and his colleague, Hyungmin Park, decided to find out how these unexpected fliers stay aloft.

– Manatee Subspecies Genetically Confirmed, but Diversity Challenge Looms

ScienceDaily (Sep. 13, 2010) — The first genetic study to compare nuclear DNA of endangered Antillean manatees in Belize with Florida manatees confirmed their designation as separate subspecies. Belize’s manatees, however, were found to have extremely low genetic diversity, raising questions about their long-term genetic viability.

– Ending the Oceans’ ‘Tragedy of the Commons’

ScienceDaily (Sep. 15, 2010) — Leading international marine scientists are proposing radical changes in the governance of the world’s oceans to rescue them from overfishing, pollution and other human impacts.

– Salmon’s Body Language Tells All: Body Language Can Be an Indicator of Stress or Well-Being in Fish

ScienceDaily (Sep. 15, 2010) — Behaviour can be an indicator of stress or well-being in fish, new research confirms. Automatic photo analysis may make it possible to continuously monitor and interpret fish behaviour.

– Fish Schools and Krill Swarms Take on Common Shape

ScienceDaily (Sep. 18, 2010) — When fish or tiny, shrimp-like krill get together, it appears they follow the same set of “rules.” According to a new study published online on Sept. 16 in Current Biology, a Cell Press publication, shoals of fish and swarms of krill hang out in groups that take on the same overall shape; it’s not a simple sphere, a cylinder, or ovoid, but something more akin to an irregular crystal, the researchers say.
