Washington and Jefferson College students create semester-long field studies

When late-winter snow falls on a nature preserve near Washington, Pa., melted divots surround Eastern skunk cabbages. The cabbage’s capability to generate heat is one of many topics students in a Washington and Jefferson College ecology course investigate during a single semester of classes. The ecology class starts with a trip to the Abernathy Field Station, a natural area where all students and faculty can contemplate science, literature, art or life itself. Students in the school’s ecology capstone each choose a topic to study. At the end of the semester, they draw their conclusions and share findings with students, professors and the public at a student research symposium.

SUNY ESF/Syracuse U. study finds in-stream restoration structures effective

Planning stream restorations is becoming more important as the number of projects increases nationwide, in efforts to enhance water quality and habitat health of surrounding areas. Researchers at the State University of New York College of Environmental Science and Forestry (SUNY ESF) and Syracuse University led a study of two streams in upstate New York that had undergone restoration. They found restoration work created large areas of "transient storage" where water is temporarily retained behind restoration structures that enhanced downwelling to rates not observed in reference reaches. In natural streams, these transient storage zones are known to host biological and chemical processes that allow the stream to clean itself.

Global warming threatens California fish with extinction

A new study from the Center for Watershed Sciences at the University of California, Davis suggests that salmon and other freshwater fish in the state are apt to become extinct during the next century if global warming persists,  UC Davis has announced . The study was based on a compilation of expert opinions centered on how increased temperatures might affect fish populations. The research showed that 82 percent of the 121 native fish species present in California are likely to become extinct, while 19 percent of California’s 50 non-native fish species risk going extinct. Increased temperatures are especially dangerous for freshwater fish that need cooler water temperatures, such as salmon and trout, as their preferred habitats are likely to be put in jeopardy.
