UD research investigates migratory birds’ habitat concerns on coffee farms
Coffee grown under a tree canopy is promoted as good habitat for birds, but recent University of Delaware research shows that some of these coffee farms may not be as friendly to our feathered friends as advertised. (more…)
UD alumna studies leatherback sea turtles in Costa Rica
It’s not every day that you get to see a creature that has been around for 110 million years emerge from the ocean and lay its eggs on the beach. Unless, of course, you’re like University of Delaware graduate Lauren Cruz, who spends her days in Costa Rica with the Leatherback Trust studying leatherback sea turtle nesting ecology.
Cruz, a 2013 graduate who studied wildlife conservation in UD’s College of Agriculture and Natural Resources, is tracking the demographics of the turtles that nest at Playa Grande and Parque Nacional de las baulas — which translates to the park of leatherback sea turtles — and spends her nights with a team patrolling the beach looking for nesting turtles.

UD researchers use weevils to check spread of prolific mile-a-minute weed
Mile-a-minute weed has declared war on Doug Tallamy’s yard. This non-native, invasive vine is growing up his trees, scrambling over shrubs and smothering tree seedlings. By blocking sunlight, it weakens a plant by reducing its ability to photosynthesize.
Mile-a-minute doesn’t care one whit that Tallamy, professor and chair of the University of Delaware’s Department of Entomology and Wildlife Ecology, is a highly respected proponent of native gardening who doesn’t believe in planting any non-natives, let alone a highly invasive non-native.
“The deer brought mile-a-minute from our neighbor’s yard three years after we moved in,” says Tallamy. “We had just a few plants the first year, a few hundred the second year, and 20 trillion the third year.” (more…)
