Scientists studying genetic variation and gene flow in a population of tortoises (Gopherus agassizii) in California’s Mojave Desert, were surprised recently to discover that two roads built in the desert in the 1970s had a noticeable impact on the population’s genetic structure. [...more]

Researchers from the Smithsonian Conservation Biology Institute, Hawaii Institute of Marine Biology and other partnering organizations spent two weeks at the end of November collecting sperm and embryonic cells during spawning from two species of coral and have built the first frozen repository for the Great Barrier Reef.

Nearly 20 years after the Smithsonian Conservation Biology Institute became the first to produce an Eld’s deer fawn through artificial insemination, SCBI scientists have now contributed to the birth of the first Eld’s deer via in vitro fertilization. [...more]
School's nearly back in session, but the seven young lions at the Smithsonian's National Zoo have been working hard through the summer months! Instead of learning their ABCs, they're learning behaviors that help animal care staff evaluate their health, including opening their mouth, showing their paws, getting up on a bench and laying down in practice to receive a vaccination. We've been tracking their achievements—and adorable blunders—on camera. They're certainly earning their meatballs and we think you'll be impressed by their progress. According to their teachers, keepers Rebecca Stites and Kristen Clark, all seven lions earn the same grade for effort: A+ [...more]
Researchers at the Smithsonian Conservation Biology Institute have discovered why older females are rarely able to reproduce—and hope to use this information to introduce vital new genes into the pool. SCBI scientists and collaborating researchers analyzed hormones, eggs and the uteri of 34 cheetahs at eight institutions, and determined that while [...] [...more]
Five cheetah cubs were born May 28 to 6-year-old Amani at the Smithsonian Conservation Biology Institute in Front Royal, Va. Amani is a dedicated mother according to keepers, who have observed her nursing and grooming the cubs. [...more]
The National Zoo’s great cat program recently expanded with the arrival of two-and-a-half-year-old female Sumatran tiger, Damai, who is now out of quarantine and spending time outside in her exhibit where visitors can see her. [...more]
This fossil represents a new genus and species of extinct aneuretopsychid, Jeholopsyche liaoningensis, recently described in a paper in the journal ZooKeys by Conrad Labandeira of the Smithsonian’s National Museum of Natural History, and Dong Ren and ChungKun Shih of the College of Life Sciences, Capital Normal University, Beijing. The aneuretopsychidae are a family of long-proboscid insects that lived in Asia from the Late Jurassic to Early Cretaceous. The paper documents the first formal record of fossil Aneuretopsychidae in China. The new fossils reveal previously unknown and detailed structure of the mouthparts, antennae, head, thorax, legs and abdomen of this distinctive insect lineage.
