NSF Web Site Press Release 11-008 Putting the Dead to Work Conservation paleobiologists dig deep to solve today's ecological, evolutionary questions Conservation paleobiologists are looking at ecology and evolution in new ways. Credit and Larger Version January 13, 2011 Conservation paleobiologists--scientists who use the fossil record to understand the evolutionary and ecological responses of present-day species to changes in their environment--are putting the dead to work. A new review of the research in this emerging field provides examples of how the fossil record can help assess environmental impacts, predict which species will be most vulnerable to environmental changes, and provide guidelines for restoration. The literature review by conservation paleobiologists Gregory Dietl of the Paleontological Research Institution and Cornell University and Karl Flessa of the University of Arizona is published in the January, 2011, issue of the journal Trends in Ecology and Evolution. The National Science Foundation (NSF) funded the research. "Conservation paleobiologists apply the data and tools of paleontology to today's problems in biodiversity conservation," says Dietl. The primary sources of data are "geohistorical": the fossils, geochemistry and sediments of the geologic record. "A conservation paleobiology perspective has the unique advantage of being able to identify phenomena beyond time scales of direct observation," Dietl says. Such data, says Flessa, "are crucial for documenting the species we have already lost--such as the extinct birds of the Hawaiian islands--and for developing more effective conservation policies in the face of an uncertain future."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
