Chlorophyll fluorescence emission: scaling from the leaf to satellite remote sensing – Chlorophyll, the green pigment in leaves, exhibits the unusual feature of re-emitting a small fraction of the light it absorbs; that is, it fluoresces. For decades, 生理学家检查单个叶片,利用荧光发射的强度来探测光合作用的内部运作和叶片对环境胁迫的反应. Only recently, instruments capable of measuring chlorophyll fluorescence have been mounted on towers and satellites, allowing for remote sensing of the fluorescence of whole forests. We partner with collaborators at Boston University, Caltech, UC - Davis, the University of Utah, 在其他地方了解遥感叶绿素荧光如何加深我们对森林及其对全球气候变化的反应的理解. This work is supported by grants from NASA, NIST, and the NSF.
The ecophysiology of eastern dwarf mistletoe infection – Eastern dwarf mistletoe, a diminutive parasitic plant, can fell a mature white spruce in a matter of years. Curiously, a closely related host growing in adjacent forest stands, red spruce, tolerates infection and even succeeds in killing the parasite. Students, collaborators, 我试图确定导致白云杉死亡事件的因果链,并将其与红杉耐受性的机制进行对比, 通过全树生长和林分动态,从基因表达和激素代谢的尺度上进行观察. 我们研究的寄主-寄生虫的相互作用是由19世纪红杉/冷杉为主的森林被移除,以创造随后被白云杉遗弃和重新殖民的牧场所形成的. We conduct this work at several sites along the Maine coast, including Monhegan Island.
Jaret Reblin, Associate Director of the Schiller Coastal Studies Center and Laboratory Instructor in Biology, is a close collaborator on many aspects of these and other projects.
Art, Ecology, and the Resilience of a Maine Island: The Monhegan Wildlands – Monhegan Island lies ten miles off the Maine coast, the outermost island of Muscongus Bay. 蒙黑根荒原——岛上80%的未建成保护区——经历了一段充满活力的历史,其中包括为了放牧而砍伐森林, pastureland abandonment, the introduction and eventual removal of deer, and the preservation of an ancient forest in the island interior. Monhegan Island has been a renowned artist colony for over a century. Painters and photographers have depicted this dynamic landscape since the middle of the 19th century. 与弗兰克·古德伊尔(买球平台艺术博物馆联合馆长)和詹妮弗·派伊(蒙黑根艺术博物馆馆长)合作 & History) and numerous other contributors (including Bowdoin undergraduates), 我们通过汇集艺术作品来描述蒙黑根荒原的动态历史及其管理, cartography, and illustrations of ecological phenomena. This will culminate in exhibitions at the BCMA opening in December, 2024 and MA&H in July 2025 and an accompanying catalogue.
