GPS Traffic Maps for Leatherback Turtles Show Hotspots to Prevent Accidental Fishing Deaths

The leatherback turtle in the Pacific Ocean is one of the most endangered animals in the world. Its population has declined by more than 90 percent since 1980. One of the greatest sources of mortality is industrial longlines that set thousands of hooks in the ocean to catch fish, but sometimes catch sea turtles as well. Using modern GPS technology, researchers are now able to predict where fisheries and turtles will interact and to reduce the unwanted capture of turtles by fishermen.

Paperwasps in Different Castes Develop Different-Sized Sensory Brain Structures

A queen in a paperwasp colony largely stays in the dark. The worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new study led by Drexel professor Sean O'Donnell, PhD, indicates that the brain regions involved in sensory perception also develop differently in these castes, according to the different behavioral reliance on the senses.

Gephart, Jr., president and CEO of the Academy of Natural Sciences of Drexel University, shake hands over an agreement to form an environmental research and educational consortium at Lacawac in the Pocono Mountains. The consortium also includes Drexel University.

Environmental Research Consortium Formed with Lacawac Sanctuary, Drexel and Academy of Natural Sciences

Lacawac Sanctuary Foundation, the Academy of Natural Sciences of Drexel University and Drexel University today announced an agreement to form an environmental research and education consortium at Lacawac Sanctuary, a popular National Natural Landmark and ecological field research station in the Pocono Mountains.

Drexel Scientist Studies Hurricane Sandy Impact on NJ Coastal Wetlands One Year Later

In a stroke of good luck, Drexel's Dr. Tracy Quirk captured detailed measurements of water level and salinity at a range of coastal wetland sites, even as they were overtaken by Hurricane Sandy. After the storm, she began working on an intensive year-long project, funded by the National Science Foundation, to evaluate ecosystem processes in New Jersey’s salt marshes before, during, and for a year following Hurricane Sandy. Quirk is beginning to analyze findings from the study now.

Drexel Study Shows Longline Fishery in Costa Rica Kills Thousands of Sea Turtles and Sharks

The second-most-common catch on Costa Rica’s longline fisheries in the last decade was not a commercial fish species. It was olive ridley sea turtles.

Co-op Leads Drexel Student to Valleys and Mountains of Mongolia

Environmental science pre-junior Anna Gourlay wasn’t looking to go international for her first co-op experience, but somehow she ended up camping in Mongolia.

Academy watershed grant

Academy of Natural Sciences to Provide Scientific Guidance in Watershed Protection

The Academy of Natural Sciences has received a major grant from the William Penn Foundation to support watershed protection and restoration in the Delaware watershed.

Academy historical marker

New Historical Marker Dedicated to Academy of Natural Sciences Founding in 1812

State and local officials gathered this week in the oldest part of the city to dedicate a historical marker near the site of the founding of the Academy of Natural Sciences two centuries ago.

Drexel at Philadelphia Science Festival and Philly Tech Week

As part of city’s vibrant scientific and technological community, Drexel University will play a big role in the 2013 Philadelphia Science Festival and Philly Tech Week on April 18-28. From a 29-story video game, to cutting-edge robotics, to an interactive Jazz concert, Drexel’s students, faculty and professional staff will be part of the programming for both week-long celebrations of the inquisitive and innovative spirits that are part of the fabric of the city.

Fossil Fish Brings Broader Understanding of 'Fish-Eat-Fish' World

Scientists from the Academy of Natural Sciences of Drexel University have described another new lobe-finned fossil fish species from the same time and place in the Canadian Arctic as the famous precursor to limbed animals, Tiktaalik roseae, which they discovered several years ago.

Academy Scientists Receive Top Honors for Long-Term Research and Training Initiatives in Mongolia

Dr. Clyde Goulden, a pioneering ecologist and director of the Asia Center of the Academy of Natural Sciences of Drexel University, has devoted his life to studying climate change and how it is affecting Mongolian herders and the pristine 2-million-year-old Lake Hövsgöl. His efforts have now been recognized with Mongolia’s highest award to foreigners, the Order of the Polar Star. In a separate honor, Dr. Jon Gelhaus, Academy curator of entomology and professor in Drexel University’s College of Arts and Sciences, has received the Kublai Khan medal for his scientific achievements in Mongolia.
