Roadside Research from the New Jersey Pinelands and Coast to Coast

Three doctoral students from Drexel's Laboratory of Pinelands Research are presenting their work with northern pine snakes and the Pine Barrens gentian at the Ecological Society of America meeting, after doing some new roadside research during their cross-country drive to Sacramento.
In the Drexel team's experiments, flies died after an average of 5.8 days when consuming a diet of the sweetener erythritol.

You Catch (and Kill) More Flies with This Sweetener

In a study that began as a sixth-grade science fair project, researchers at Drexel University have found that a popular non-nutritive sweetener, erythritol, may be an effective and human-safe insecticide. Erythritol, the main component of the sweetener Truvia®, was toxic to fruit flies in the Drexel team’s study.

A Tiny, Toothy Catfish with Bulldog Snout Defies Classification

Kryptoglanis shajii is a strange fish — and the closer scientists look, the stranger it gets. This small subterranean catfish sees the light of day and human observers only rarely, when it turns up in springs, wells and flooded rice paddies in the Western Ghats mountain region of Kerala, India. Scientists at the Academy of Natural Sciences of Drexel University have recently provided a detailed description of this fish's bizarre bone structures.

Academy Gets $3.2M Grant to Protect Drinking Water

The Academy of Natural Sciences of Drexel University will coordinate and oversee ecological monitoring projects by more than 40 national and regional environmental organizations in eight designated geographic areas in Pennsylvania, New Jersey, New York and Delaware.

Carol Collier Joins Academy of Natural Sciences as Senior Advisor for Watershed Management and Policy

Carol R. Collier, an experienced leader in regional watershed management and planning, has joined the Academy of Natural Sciences of Drexel University as its Senior Advisor for Watershed Management and Policy. Collier recently retired as Executive Director of the Delaware River Basin Commission, a position she held for more than 15 years.

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.
Jake Owens

Drexel grad student has one of the 'worst jobs in science'

Jake Owens spent a month surrounded by criminals with machetes and rotting meat in Africa, earning notice from Popular Science magazine.

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.
Foreground: Dr. Tracy Quirk uses a Surface Elevation Table (SET) to measure relative sediment elevation change in a salt marsh in Barnegat Bay, NJ while staff scientist Linda Zaoudeh records data. Background: Staff scientist Stephanie Leach and Drexel environmental science graduate student Viktoria Unger use Real Time Kinematic (RTK) satellite navigation with GPS technology to measure the elevation of the marsh.

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.
