BIOLOGICAL CONTROL IN PROTECTED NATURAL AREAS by Susan

Science and Natural History

P rior to the blight epidemic, American chestnut (Castanea dentata Borkh.) was one of the most important timber and nut-producing tree species in eastern North America (U.S. Census Bureau 1908). Its native range extended from southern Maine and Ontario in the north to Georgia, Alabama and Mississippi in the south (Sargent 1905). It now exists primarily as stump sprouts across its entire native ...

Air quality in natural areas: interface between the public, science and regulation.

Natural areas are important interfaces between air quality, the public, science and regulation. In the United States and Canada, national parks received over 315million visits during 2004. Many natural areas have been experiencing decreased visibility, increased ozone (O(3)) levels and elevated nitrogen deposition. Ozone is the most pervasive air pollutant in North American natural areas. There...

Biological and Chemical Microstructure in Coastal Areas

We seek to gain a quantitative understanding of the physical, chemical, biological, and optical dynamics that structure the planktonic ecosystem on the scales of the organisms. By quantifying the variability of the organisms and their environment at the scales that the organisms live their lives, we will gain insight into the dynamics that create structure and influence the function of the plan...
