At dusk, Carolyn Rinaldi and her 14-year-old daughter sit silently on the shores of the lake at Wadsworth Falls State Park in Middletown, Conn. Then their ears go into overdrive. For three minutes they count the different grunts, gribbets, croaks and peeps emanating from frogs and toads resident in the wetlands. Read the rest of this entry »
There are millions of people taking part in citizen science across the world, and thousands of practitioners – scientists, educators, computer scientists, and activists – organizing citizen science projects. Citizen science has emerged as a new discipline, with novel ways of enabling scientific research, informing policy and conservation, and motivating learning.
New organizations, such as the Citizen Science Association, the European Citizen Science Association, and Citizen Science Network Australia, are helping practitioners connect with each other to solidify best practices and training. Other organizations provide cyberinfrastructure to help administer citizen science projects, like Zooniverse for online projects and CitSci.org and Wildbook for field projects. Other organizations, like Public Lab and Global Community Monitor, support grassroots citizen science. Still other organizations, like SciStarter, connect participants with projects.

This June, I walked the wilds of Los Angeles looking for lizards. And snakes. And turtles. And because I was finally looking for them, I also began seeing them—and isn’t that a basic truth of life as well as citizen science?
I visit Los Angeles for ten days twice a year as a teacher for the low-residency MFA graduate writing program at Antioch University. My time in nature is mostly spent in a few long runs near my hotel and in walking back and forth from the hotel to the university campus. This summer, wherever I went, I also took along my camera. I was on a mission for the Reptiles and Amphibians of Southern California (RASCals) citizen science project—to document any reptile or amphibian I came across and to send that image to the Natural History Museum of Los Angeles County.

Are you a resident of the northern US or Canada? You can help scientists to spot amphibians!
Welcome Spring! As the temperature rises, the beauty of spring unfolds: snow melts, flowers bloom, and birds begin to chirp. In the amphibian world, spring marks the beginning of breeding activities. Among amphibians, wood frogs and spotted salamanders are usually the first to breed, laying eggs (spawns) in short-lived pools, ponds and wetlands.
Scientists like Dr. Stephen Spear, from the Orianne Society, are interested in monitoring amphibian breeding activity for further insight into the effect of climatic changes on certain ecosystems. For instance, a cold spell in spring may disrupt the breeding activities of amphibians. Additionally, the presence of commonly found amphibian species, such as wood frogs and spotted salamanders, indicates a relatively healthy landscape, which helps determine important conservation areas.
Monitoring the timing of breeding activity can be tricky. Wood frogs and spotted salamanders are found in wetlands across various states, including Alaska, southeastern states such as Georgia and Tennessee, northeastern states such as New York and Maine, and large parts of Canada. Realizing a small team would be ineffective in monitoring wood frogs and spotted salamanders widely distributed across the U.S. and Canada, the scientists sought support from citizen scientists.
Last year, the Orianne Society launched the citizen science project ‘Snapshots in Time’, providing participants with a unique opportunity to identify, observe, and photograph the various stages of amphibian life that they found near their homes. In 2014, citizen scientists contributed over 100 such observations. More observations reported from southern states as compared to northern states, likely due to the differences in the breeding season. In states such as North Dakota, Wisconsin and Michigan, breeding season spans from April to June, unlike southern states where breeding activity begins in January. This year, the project hopes for more observations from the northern states. Compared to the adult and egg stages of amphibian life, larvae are more difficult to spot, and only 15 percent of the observations were of the larvae and metamorphic stages. Some participants were able to see a fascinating courtship ritual – a well choreographed dance by salamanders to attract their partners.
According to Dr. Spear, spotted salamanders live on land but breed in wetlands. People who study spotted salamanders look forward to ‘mass migration’, an intriguing breeding activity where, on a rainy night, salamanders parade en masse from land to wetlands. That’s an exciting natural history experience.
