Artificial light at night has a profound effect land-based life – from birds to fireflies to humans. But a new study suggests we need to widen our view to include light pollution‘s effect on coastal marine ecosystems, impacting everything from whales to fish, coral to plankton.
This new synthesis of marine light pollution science is published in the journal Aquatic Conservation: Marine and Freshwater Ecosystems. [Read more…] about Study: Light Pollution Threatens Coastal Marine Systems
It’s evening, and you’re in the forest. You close your eyes and inhale the sharp, sweet, turpentine scent of pine. The air is still, yet the branches overhead seem to nod at your presence. You shine a flashlight and catch a glimpse: a fleeting, tiny ball of fur, arms and legs outstretched, tail like a rudder, gliding through the night. It lands on a tree trunk, pauses, then launches itself again. A flying squirrel, in its glory. [Read more…] about When North Meets South: Flying Squirrel Hybrids
A caterpillar eats and eats, becomes a chrysalis, and after a period of metamorphosis emerges as a beautiful butterfly! Except, sometimes… it doesn’t quite work that way.
Occasionally, while sitting on my deck, I spot smallish, orange butterflies landing on our hop plants. Their upper wings, about two inches across, are bright orange with dark blotches and eyespots, but camouflage brown on their underside. These are eastern comma butterflies (Polygonia comma), named for a silvery marking on the hind wing. If I look closely after one has flapped away, I can find one or two tiny, peridot eggs that it left behind on a hop leaf. [Read more…] about Chrysalis Surprise: A Parasitoid Wasp
Humans aren’t the only ones leaving town when city heat becomes unbearable. A study done on 336 cities in China concludes that heat-retaining buildings and paved surfaces are directly related to a loss in bird diversity. These findings from scientists at Zhejiang University and the Cornell Lab of Ornithology are published in the journal Science of the Total Environment.

Each fall deciduous trees, ice-cream stands, and marinas close for the same reason: as daylight dwindles and cold creeps in, they become less profitable. When income dips down to equal the cost of doing business, a wise proprietor will turn off the lights and lock the doors until spring.
Some enterprising holdouts stay solvent longer than others who are in the same business. Perhaps they have less competition or a better location. Conversely, a few businesses close their shops at the first whiff of autumn. Those are the ones that just barely scrape by at the height of summer.

Founded in 1986, the University at Albany’s Science and Technology Entry Program (STEP) works to promote diversity, equity, and the inclusion of historically underrepresented high school students pursuing careers in Science, Technology, Engineering, and Math (STEM).

This fall the Cornell Biological Field Station at Shackelton Point in partnership with the New York State Department of Environmental Conservation (DEC) will be initiating a three-year telemetry study of adult walleyes in Oneida Lake to identify spawning sites, describe seasonal movement patterns, describe habitat use throughout the year, and determine where post-spawn walleye go after they have been processed at the Oneida Fish Hatchery.

Though the phrase “garbage in, garbage out” is a decades-old caution for techies to be mindful when writing code or entering data, I thought my mom invented it. It was her stock retort when we kids asked why two hours of Saturday cartoons was plenty: “Garbage in, garbage out. Fill your heads with foolishness, and you’ll act that way.” I guess she was afraid we’d start chasing roadrunners across the desert, which typically leads to sprinting off cliffs and being struck by falling anvils.
It turns out she had a point. Numerous studies confirm that exposure to graphic TV violence raises a child’s level of aggression and anxiety in the short term, and is a sound predicter of hostile behavior as an adult. [Read more…] about Fly Research Yields Possible Trauma Treatment
New York State Department of Environmental Conservation (DEC) is seeking hunters to participate in a multi-year study of non-lead ammunition impacts on the State’s eagle conservation efforts. DEC is partnering with the New York Cooperative Fish and Wildlife Research Unit at Cornell University, U.S. Geological Survey, and Conservation Science Global on the study to determine the reduction in bald eagle and golden eagle deaths that can be achieved from increased use of non-lead ammunition for deer hunting.

The New York State Department of Environmental Conservation (DEC) is partnering with the Cary Institute, NY Natural Heritage Program, Vermont Center for Ecostudies, and SUNY New Paltz biology department to monitor birds, such as the Bicknell’s thrush, that nest in rare mountaintop habitats.
