Drawing a Line on Preservation

Conservation programs that perform captive breeding for endangered animals  – like the Duke Lemur Center – face a difficult choice when choosing pairs to breed.

DNA analysis suggests that some populations of rare animals which have been isolated from one another by fragmented habitat may in fact be distinct sub-species. If they've been separated long enough without mating opportunities, their genomes have evolved subtle differences.

Flying high on stolen wings

Guest post by Viviane Callier, Duke biology

The wing color patterns on some butterfly species have evolved to copy wings on other butterfly species. In Heliconius butterflies, which are toxic to birds, the convergence of several species on the same wing color pattern gives them all mutual benefit – birds recognize one pattern saying “I’m poisonous; don’t eat me!"

Mining Beneath the Sea

If mountaintop mining were being conducted 1600 meters under the ocean – where very few people would ever see it – would it make any difference?

Well, it just might, says Cindy Lee Van Dover, director of the Duke Marine Lab and one of the world's authorities on the unique life forms surrounding deep sea hydrothermal vents.

Sir Richard's Possible Folly

Moving animals, like the ring-tailed lemur, from one continent to another to save the species hasn't been done often and typically isn’t successful.

But that hasn't deterred businessman and adventure tycoon Sir Richard Branson from announcing plans to import 30 ring-tailed lemurs from global zoos to his private island of Moskito, located in the Caribbean.

Putting Values on Resources

“Unless you know that [a resource] is going to be in your family for a very long time, you usually don’t manage it sustainably,” evolutionary anthropology professor Thomas Struhsaker said during a panel discussion, March 25.
