Expert in Forestry, Soil, environmental (atmospheric) pollution
As an ecosystem ecologist, Expert has conducted extensive research on forest and grassland ecosystems and has advised the National Science Foundation and other governmental agencies on funding research dealing with terrestrial ecosystems. His academic background is heavily weighted toward forests. His B.S. and M.S. degrees are in Forestry and his professional specialization at the University of Minnesota is Forest Soils.
One area of Expert's expertise and experience is in peatlands, especially those of Minnesota. He taught an advanced undergraduate/graduate level class at the University of Minnesota that dealt exclusively with peatlands. Expert has conducted extensive studies of peatlands. He has studied both bogs and fens, the two major hydrologic groupings of peatlands, and he understands the role of peatlands in the hydrologic cycle. He can knowledgeably converse on the topic of peatland formation, both terrestrialization and paludification. He has evaluated peatlands, including extensive studies of their vegetation, water chemistry, hydrology, and the properties of the peat that is resident in those peatlands. Such evaluations relate to the suitability of peatlands for development.
Expert has been involved in conducting, reviewing, and evaluating research dealing with the effects of acid deposition, including acid rain, on natural aquatic and terrestrial ecosystems. The deposition of both natural and man-influenced chemicals from the atmosphere to terrestrial ecosystems is a continuing concern. Expert is conversant in much of the work related to deposition of acidic materials and heavy metals, including mercury, to terrestrial systems.
He has measured biomass of plant communities (natural vegetation) and is acquainted with global distribution of biomass in terrestrial ecosystems.
Expert's technical training and much of his work have focused on the relationship between vegetation and soil in forests. He has extensive experience in soil classification and mapping, and understands the relationships between soil map units and forest productivity, and the effects of forest harvest activities on soil properties.
As a component of his professional activities, Expert has personally characterized many soils and has advised fellow scientists, students, and other professionals in soil characterization.
Expert has conducted research on wetland structure and function, specifically peatlands.
Expert has conducted extensive research on terrestrial ecosystems, especially forested systems, but also has knowledge and experience in many other terrestrial systems. Such research includes many kinds of ecosystem measurement, and he understands the advantages and disadvantages of various measurement systems. As part of his study of ecosystems, he has conducted multivariate analysis of vegetation data in order to understand its variation in time and space. He has published extensively on vegetation ecology, especially with emphasis on the abiotic portions of the ecosystem.
Expert understands and is acquainted with concepts such as hydrography, base flow, storm flow, runoff, and variable source area. Wetland hydrology is a subcategory of watershed hydrology, is misunderstood by many. Expert understands the unique hydrology of wetlands and how their hydrologic behavior is included within the more general category of watershed hydrology.
