Description: J:\public\vt.gifIn the memory of the faculty and students at Virginia Tech who died tragically through senseless acts of violence, 16 April 2007.  Though their voices have been silenced, their spirits still sing.

 As a father and professor/teacher, I display this in memory of the lives of 20 children and 6 teachers brutally murdered in Newtown, CT, 14 December 2012.


I have been a member of the faculty since 1990 and teach courses in ecology and plant ecology. My research interests perhaps can be described best as broad-based within the general area of plant ecology, as may be seen in my publication record, with papers published in over 30 different journals. Most of what I do lies at the boundary between the levels of terrestrial plant communities and ecosystems. I am particularly interested in the movement and cycling of plant nutrients within terrestrial ecosystems. Directly related to this are interests in fire ecology and the effects of fire on nutrient cycling and on plants and soils in fire-prone ecosystems. Also related to my ecosystem approach to ecological research is an interest in atmospheric deposition and precipitation chemistry. This interest has led to the study of pollutant conditions (acid deposition and ozone) in forested areas.

My interests at the level of the plant community are focused predominantly on forest community ecology. I am particularly interested in secondary succession and the species dynamics of the herbaceous layer of forests, as well as the variety of biotic and abiotic factors that influence species composition and change within this vegetation stratum. My future research plans reflect extensions of previous work in the following three areas: (1) vegetation dynamics in forest ecosystems, (2) nitrogen dynamics of forest ecosystems, and (3) species composition and stand structure in old-growth longleaf pine forests.

Forest vegetation

Much of my current work, as an extension of earlier research in other forest types, is focused on factors that affect the herbaceous layer (vascular plants <1 m in height) of central Appalachian hardwood forests. Recent work, carried out at the Fernow Experimental Forest (FEF), West Virginia, has generated the hypothesis that herb layer development is nutrient-limited early in secondary succession following forest disturbance, but becomes light-limited later in succession. My future research plans include testing this hypothesis further experimentally in other forest types.

 

Fernow Experimental Forest    Description: J:\public\fernowsign.jpg

Work at this same site has generated another hypothesis concerning successional changes in the herbaceous layer of hardwood forests, one that has important implications for ecosystem management of forests and its effects on plant diversity. This hypothesis states that 1) the temporal shift in processes which control species composition following disturbance (from allogenic to autogenic factors) leads to a linkage in species composition between the overstory and herbaceous strata, and 2) the degree to which forest management alters species composition of forest ecosystems may by tied to the degree of alteration of the link between strata. I co-edited a book (with Dr. Mark R. Roberts, formerly of the University of New Brunswick, Canada) that examines the ecology of the herbaceous layer in forests of eastern North America (see below).

Nitrogen dynamics

Another area of current research interest and activity is focused on nitrogen (N) dynamics in a central Appalachian hardwood forest. Most of my time is spent on testing several hypotheses concerning the phenomenon known as N saturation, which posits that, for impacted forests in parts of Europe and North America, N inputs associated with acidic deposition are exceeding demand of N by the biota. This work involves in situ incubations of mineral soil and organic horizons to examine soil N dynamics in a treatment watershed (receiving aerial N additions to the entire watershed) and two untreated control watersheds of differing stand ages. Annual and seasonal patterns of soil N dynamics are related to watershed differences in canopy and herbaceous layer tissue N and in stream chemistry. Results to date have shown that several watersheds of FEF have become N saturated from high levels of ambient N deposition.

In collaboration with Dr. Mary Beth Adams of the USDA Forest Service, I have recently expanded the questions of N saturation in montane hardwood forests to include the interactive effects of forest harvesting and N saturation on forest soil sustainability and productivity. A major threat to sustainability in central Appalachian forests is the loss of base cations via biomass removal and leaching. Future plans include continuing this work for several years.

Some of this work is summarized in various chapters in a book recently published by Springer.  Click on the image of the book's cover to go to the book's web page at Amazon.

I am also collaborating with Dr. Bill Peterjohn of West Virginia University on a project funded by the National Science Foundation Long-Term Research in Environmental Biology (NSF LTREB) program.  Through this project, we are essentially extending the original sampling period of in situ incubations.  Beginning with the 2009 growing season, we have been revisiting sample plots to evaluate further the response of the herbaceous layer to N treatments.

Old-growth longleaf pine

I initiated a long-term study of species composition and stand structure of the Boyd Tract in the Sandhills region of North Carolina in 1989. The Boyd Tract, part of Weymouth Woods-Sandhills Nature Preserve, is unique as a longleaf pine study site for two reasons. First, at approximately 66 ha, it is the largest stand of old-growth longleaf pine the state, indeed, one of the larger stands anywhere. Second, as of the initiation of the study, the Boyd Tract had not experienced significant fire (an environmental requirement for longleaf pine regeneration) for more than 80 years. Thus, this site has provided the opportunity to study a longleaf pine stand that has not experienced the disturbance of forest harvesting, but has experienced the disturbance of chronic fire exclusion. Results to date indicate that species composition under these conditions is closely related to soil variables (e.g., texture, moisture, and nutrients). Furthermore, higher clay content soils have allowed the development of a forest type more closely resembling those of the adjacent North Carolina Piedmont than those typical of the Sandhills.

Boyd Tract, NC    Description: J:\public\llf.jpg

Future work will look more closely at the age distributions of longleaf pine stems of the Boyd Tract. In addition, future work will examine the relationships between longleaf stem age and stem size along an elevation/texture gradient and will use these relationships as basis for comparison (in collaboration with Dr. Bill Platt of Louisiana State University) to those of another old-growth longleaf stand, the Wade Tract of southern Georgia.

 

I am co-author of a textbook on the ecology of terrestrial plants. I use this book as a text for my course here at Marshall University—Plant Ecology (BSC 430/530).

Teaching:

I primarily teach three courses here in the Department of Biological Sciences at Marshall University:

Principles of Biology (BSC 121)

Principles of Ecology (BSC 320)

Plant Ecology (BSC 430/530)

 

Writing is a very important part of the scientific process.  I stress writing in my classes.  In this section, one will find useful links/items that should be helpful when writing scientific papers/reports.

Here is a very useful paper as a general reference on how to write scientific papers (HIGHLY RECOMMENDED):  Carraway (2006)

Here is a link for the classic writing manual, Elements of Style, by Strunk and White:  Elements of Style

Biology Club

I serve as faculty advisor for the Biology Club.  Please follow this link to go the web page:  Biology Club.  If you are a biology major at Marshall University, or just a student who is interested in biology in general, please consider joining us.


Personal Interests:

Outside of my professional interests in science, biology in general and plant ecology in particular, I am interested in several enjoyable activities, including tennis, wine, basketball, reading, and photography. More important than any of these professional or personal activities and interests is the honor I have of being the father of two great children--23-yr old Rachel and 20-yr old Ian.  Currently, Ian is Midshipman 2nd Class at the United States Naval Academy; Rachel is a second-year graduate student at Duke University, work toward the degree of Masters of Divinity.

I am also the grateful husband of a wonderful woman, Laura.

Laura holds the position of Executive Director of the United Way of the River Cities, Inc..

...and our sweet dog Jesse!

   

I am an Elder at Enslow Park Presbyterian Church.

One of my more passionate "hobbies" is NCAA basketball--two teams in particular.  As a result of growing up in Lexington, Kentucky, I am a big fan of the University of Kentucky Wildcat basketball team.

Also, as a graduate of Duke University (see above), I am equally as big a fan of the Duke University Blue Devil basketball team.
