The objective of this study is to investigate hydrocarbon species and amounts released by red mangrove foliage and determine if these quantities warrant future research on atmospheric chemical processing of these compounds. The field investigation took place during July 2001 at Key Largo, Florida Bay, Florida. Foliage still attached to plants was enclosed in cuvettes while air of known flow rates circulated around leaves to study hydrocarbon emissions. Cuvette air samples underwent gas chromatographic analyses to determine species and amounts of hydrocarbons released by mangrove foliage. Red mangrove foliage emits isoprene and trace amounts of the monoterpenes of α-pinene, β-pinene, camphene, and d-limonene. The mangrove flowers released these latter compounds in amounts ranging from 0.5 to 10 mg (monoterpene) per gram of dry biomass per hour. These fluxes are normalized to the foliage temperature of 30 ° C. When normalized to the foliage temperature of 30 ° C and light levels of
The Southeastern Naturalist is a peer-reviewed interdisciplinary scientific journal with a regional focus on the southeastern United States. It features research articles on terrestrial, fresh-water, and marine organisms, and their environments. It focuses on field ecology, biology, behavior, biogeography, wildlife and fisheries management, taxonomy, evolution, anatomy, physiology, geology, and related fields. It is co-published with the Northeastern Naturalist (ISSN # 1092-6194). Both journals are identical in focus, format, quality, and features, thus providing an integrated publishing and research resource for eastern North America.
The Eagle Hill Institute (formerly the Humboldt Institute) is located on the eastern Maine coast and is perhaps best known for the advanced and professional-level natural history science field seminars it has offered since 1987. The Institute actively promotes collaboration in education, research, and publishing by working together with scientists from the United States, Canada, Europe, and Latin America. It publishes the Northeastern and Southeastern Naturalists, two natural history science journals for eastern North America. The Institute has a special interest in the legacy of Alexander von Humboldt, the most renowned natural scientist of the early 19th century. The Institute is working with the Eagle Hill Foundation in developing a retreat style study and meeting facility on the summit of Eagle Hill and in developing the Foundation's first journal, the Journal of the North Atlantic, focusing on peoples of the North Atlantic, their expansion into the region over time, and their interactions with their changing environment.
