Climate change doesn’t spare the smallest
Changing conditions have taken a toll on insects in the tropics, according to research by School of Arts & Sciences biologists Daniel Janzen and Winnie Hallwachs. But education and science offer a path forward, they say.
Customized kits turn students’ dining rooms into biology labs
Students in introductory biology laboratory courses in the School of Arts & Sciences used customized laboratory kits to get hands-on practice with the scientific method.
Declines in shellfish species on rocky seashores match climate-driven changes
Two decades of data from a study of Swan’s Island in Maine co-led by biologists Peter Petraitis of the School of Arts & Sciences and Steve Dudgeon of California State University, Northridge, document a slow and steady dwindling of mussels, barnacles, and snails.
