Migration assistance may help species survive climate change

As climate changes, some species will likely face unexpected challenges in migrating successfully to more suitable habitats. Dov Sax (2009) and a colleague predict that in addition to overcoming geographical barriers, species need to be able to tolerate temperature swings and unfavorable climate along the way to travel to new habitats. The ability to persist under unfavorable conditions, which some species do not have, is an important factor for survival. "There are a lot of species that won't be able to take care of themselves," Sax said. The authors suggest that managed relocation may need to be considered for some conservation efforts.

Study validates tool for detecting marine life

A new study validated the environmental DNA (eDNA) method for detecting even small populations of marine animals. The study specifically validated the use of eDNA by David Lodge and his colleagues to find invasive Asian carp in Lake Michigan. Scientists could also use the method for detecting the presence of endangered species thought to have gone extinct.

Tagging an endangered species

Stuart Pimm (1999) is blogging the story of tagging red knots, small birds that fly from the Southern tip of the Americas to the Arctic Circle and back every year. Pimm and an army of volunteers fire nets out of a cannon onto groups of birds so they can tag, measure, weigh, and release them while they stop to feed on the New Jersey shore. Pimm and his colleagues hope to better understand why the birds' numbers are declining.

Prison project contributes to conservation efforts

Nalini Nadkarni

Inmates in the Washington State prison system have been highly successful in raising Oregon spotted frogs, an endangered species, for reintroduction in Puget Sound. The project, a collaboration between Evergreen State College, the Washington State Department of Corrections, and the state Department of Fish and Wildlife, formed out of a partnership begun by Nalini Nadkarni (2004). She has also helped start a project involving the college, the prison system, and The Nature Conservancy to raise endangered prairie grasses to reseed meadows at Fort Lewis. Read recent coverage of the frog and prairie grass projects here.

Role of peer-reviewed science in species management examined

Paul Beier

Paul was interviewed by National Geographic News for a feature on November 26, 2008 about the effect of flawed science on policy to protect panthers in South Florida. He commented on ways to improve the scientific peer review process to ensure that only the best science informs species management plans.
