All across the world, scientists are tracking the movements of animals, collecting considerable data to better understand how animals migrate, what paths they take and what threats they may face along the way. A new statistical model from the Smithsonian Conservation Biology Institute (SCBI) and...

For Asian elephant keepers, working among the giants of the animal kingdom entails training, enriching and caring for the Zoo's multi-generational herd, as well as contributing to research and educating visitors about the conservation of this endangered species.

Behavior can tell the giant panda team quite a bit about the pandas, but the behaviors they exhibit are only half the story. When it comes to predicting when Mei Xiang will give birth, or when she is in the final stages of a pseudopregnancy, scientists rely on a few different factors. They monitor...

Ever since 42-year-old Asian elephant Kamala arrived at the Smithsonian’s National Zoo in May 2014, keeper Amanda Bobyack has helped her settle into her habitat. Part of that adjustment included learning husbandry and medical training behaviors that help Bobyack, her fellow keepers and the vet team...

The Kirtland's warbler is an endangered migratory songbird that breeds almost exclusively in Michigan and winters primarily in the Bahamas. The species nests on the ground and will only breed in young Jack Pine forests. Decades of fire suppression prevented the formation of new breeding habitat for...

About 100 kilometers south of Lima on the coast of Peru, an expansive community of marine invertebrates, fish and seabirds has taken up residency in a seemingly unlikely place: in the hard-bottom space created by a barrier, called a breakwater, protecting South America’s first Liquefied Natural Gas...

A new cryopreservation study has sweeping implications for wildlife conservation and human health. In a paper published July 13 in ACS Nano, the Smithsonian Conservation Biology Institute and University of Minnesota provide the first-ever reproducible evidence for the successful cryopreservation of...

In a shell of a paternity test story, Smithsonian Conservation Biology Institute (SCBI) scientists found that male desert tortoises that had been relocated from a threatened habitat to a new nearby home are reproducing at a much, much lower rate than resident males. Genetic paternity testing of 92...

The island scrub-jay, a songbird endemic to Santa Cruz Island off the coast of southern California, has made headlines in recent years for bucking evolutionary and biological trends—and is at it again this year.

In June, SCBI scientists and partners fitted the ossicones of 11 reticulated giraffes with GPS collars that send hourly data to researchers via satellite.
