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]

This photo shows developing embryonic cells of the coral species Acropora tenuis, from the Great Barrier Reef in Australia. 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 this and one other [...] [...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.

Scientists from the Smithsonian Migratory Bird Center have found that fledgling catbirds living in the suburbs are extremely vulnerable. Almost 80 percent are killed by predators before they reach adulthood. Nearly half of the deaths are connected to domestic cats. The team studied catbird nests in 3 suburban neighborhoods in Maryland: Spring Park, Opal Daniels Park, and Bethesda. Learn more about this 2011 study by clicking here.
