Progress in Coupling Plant Form and Photosynthetic Function

Author : William K. Smith

Additional Authors : Nicole M. Hughes

ABSTRACT Photosynthetic adaptation in terrestrial vascular plants involves a complex interaction of components that extend across a broad structural and spatial hierarchy, often functioning in concert with one another at multiple scales. Thus, understanding the evolutionary mechanisms leading to these adaptations requires evaluation across the entire spectrum of plant form from the chloroplast to the …


Species Diversity and Composition in Old Growth and Second Growth Rich Coves of the Southern Appalachian Mountains

Author : B. Clay Jackson

Additional Authors : J. Dan Pittillo, H. Lee Allen, Thomas R. Wentworth, Bronson P. Bullock, David L. Loftis,

ABSTRACT Because of ongoing debate over the long term impacts of logging, we conducted a study to assess if second growth (70 6 10 years) rich coves differ from old growth rich coves (. 125 years) in species diversity or composition. We sampled twenty-six 0.1 ha plots, representing these two age classes. We distributed the …

Conservation Genetics of Delphinium newtonianum Dw. Moore (Moore’s Delphinium) [Ranunculaceae], a Rare Endemic of the Interior Highlands

Author : Edith L. Hardcastle

Additional Authors : Johnnie L. Gentry

ABSTRACT Delphinium newtonianum (Ranunculaceae) is a rare endemic of the Interior Highlands. Using a single-copy nuclear gene, genetic diversity was determined for eight populations. Genetic diversity in D. newtonianum is high (37 haplotypes were identified from 80 individuals) and haplotype diversity was 0.885 + 0.016. Analysis of genetic structure indicates that populations within the Ozark …
