Step back to 1995. You have a paper address book – family, friends, business – but it’s too big. You’ve been so many places and met so many people that you can’t distinguish John Smith the college buddy from John Smith at the office. It’s time to get organized with a computer program. You buy […]

As summer comes to a close, a young person’s fancy may turn to fretting at the thought of being cooped up in a classroom. But for fans of science and nature—and by that we mean kids who like to watch clouds, hunt mushrooms, prowl around graveyards, and check out what gets squashed on the side […]

Sara Fitzsimmons is the Regional Science Coordinator at The American Chestnut Foundation The American Chestnut Foundation (TACF) is a 501(c)(3) organization dedicated to restoring the American chestnut (Castanea dentate) to its original range. Once estimated to be 25% of the Appalachian forests, the species was all but eliminated from the landscape by an imported fungal […]

On June 1, 2011 at 11:51 PM, a group of people assembled on the beach in Northpoint, New York. There was no moon shining that night, not even a sliver. The people carried flashlights or wore headlamps. They held clipboards and paper.

Their mission: to report where horseshoe crabs were spotted along the beach.

This was just one of several places along New York’s shoreline where people collect data about horseshoe crabs. Volunteers also amassed on dark beaches in Stony Brook, Staten Island, Brooklyn and Westhampton. In all, volunteers monitored the comings and goings of horseshoe crabs at ten New York beaches that night.

They are a part of the New York Horseshoe Crab Monitoring Network, a group of citizen scientists who are documenting where horseshoe crabs emerge from the water to lay eggs along beaches in New York State. On specific dates through the spring and early summer, participants collect data about the number of horseshoe crabs and identify their size and sex. They attach tags to the horseshoe crabs bulky exoskeleton and look for tags from prior years.

Guest post by Kate Atkins If your first thoughts when you hear the word “cruise” are fruity drinks with paper umbrellas, jet skis, and late nights in the hot tub: think again. Replace the hot tub with Mendenhall Glacier, the fruity drink with test tubes of fresh stream water, and the jet ski with a […]

Researchers at Penn State University need your help to study the distribution of microorganisms in household hot water heaters. Turns out your everyday hot water heater can double as a model hot spring, one of Earth’s extreme environments where important clues about microbial life in the Solar System might be found. First, researchers want to […]

It seems strange to mark the location of a fish, doesn’t it? They can swim and move away from the marker, right? I wonder while standing on a dock waiting for the boat that will take about ten of us out to a reef. There, we will scuba dive for fun and also mark the locations of lionfish, an invasive species in the Caribbean.
Volunteer divers on the Dutch island of Bonaire are helping Bonaire National Marine Park eliminate invasive lionfish from its coral reefs by marking the locations where the fish are found. A diver who spots a lionfish is instructed to attach a small flag, provided by the park, to a rock near the fish.

The answers to my questions about marking fish locations become clear once I splash into the water and see the fish and flag markers for myself. Swimming along sections of reef, I saw dozens of flags that had been placed there by divers and each had one or more lionfish hovering nearby. It turns out that lionfish don’t stray far from their particular nook of reef. They stay near the markers.

It’s illegal to hunt or in any way harm marine life in the waters surrounding Bonaire. Except, that is, for lionfish.

They are beautiful fish, placidly fluttering their glitzy ruffle of fins, and hovering next to their flags. Yet, a voracious appetite for reef fish combined with a high rate of reproduction and no known predators in the Caribbean make lionfish a threat to biodiversity. Native to the Pacific, the lionfish is an invasive species in the Caribbean.

Changing Currents, a project originating in Toronto, Canada, familiarizes middle- and high-school students with local watersheds and teaches them how to conduct water quality analyses. This is a great way for students to become environmental scientists for a day! After heading out to a local stream and donning hip waders, students collect water samples and analyze […]

Citizen science is taking off in Puerto Rico! According to a story at Ciencia PR, citizen scientists are playing an important role in the conservation efforts for the Hacienca La Esperanza Reserve, which houses the only coastal forest in Northern Puerto Rico. Through the Puerto Rico Conservation Trust’s Citizen Science Program, volunteers have the opportunity to explore and observe the […]

In July of 2009, a friend and I arrived at a lake to collect water samples for work. We had worked at the lake many times, but something was different that day: several hundred dragonflies were flying over the grass. We often saw dragonflies, but there were 50 times the usual number and they weren’t […]
