Sphagnum magellanicum
Our comparative studies focus on water and carbon dynamics in the genus Sphagnum. Here a dense colony of Sphagnum magellanicum shows the exchange surface for water loss and carbon uptake. In bryophytes, shoots also function in water transport, water holding and nutrient...

Great Waas Island Preserve
Beginning in 2013, we have participated in a global study of productivity in Sphagnum using two widespread, important peat forming species, S. fuscum and S. magellanicum. Organized by Gustaf Granath and Häkin Rydin from Uppsala Univ. and working on our study sites in New York...

Hierarchical Organization of Sphagnum Shoot Systems
Sphagnum exhibit a high degree of genetic and phenotypic variation in structure at all levels within their organization including (a) across hummock–hollow microhabitats, (b) within colonies, (c) within shoots that show variation in branch distribution and density, (d) on...

Adirondack High Peaks
Here I am on Seward Mountain, one of the 46 peaks above 4,000′ in New York’s Adirondack Mountains. In addition to supporting alpine bryophyte communities, this mountain is named for William H. Seward, Governor of New York, Secretary of State under Abraham Lincoln...

Integrated Water-driven Carbon Balance Model and Bryophyte Color Wheel
Being desiccation tolerant, bryophytes exhibit different water and carbon relations than vascular plants. The unique dynamics are illustrated graphically showing net carbon assimilation through time beginning with a wetting event at the origin. Initially, plants have a burst...

Laser Scanning of Bryophyte Canopies
Optical, non-contact laser scanning provides high resolution spatial information in three dimensions. The animation shows a scan of Pleurozium schreberi. Such scans provide quantitative information on canopy properties that can be integrated into water and carbon exchange...
