David L. Remington

BS: University of Montana, 1976 PhD: North Carolina State University, 1999 Postdoctoral: North Carolina State University. I conduct research on the genetics of complex trait variation and adaptive evolution in morphology and resource allocation in plants. The genes responsible for these processes have key roles in shaping plant responses to environmental variability and have been important in generating terrestrial biodiversity. Major topics include the genetic basis for speciation and growth form evolution in the Hawaiian silversword alliance and the genetic mechanisms of resource allocation in the rock cress Arabidopsis lyrata. We are seeking to develop the silversword alliance as an experimental system for genetic research, taking advantage of its unique phenotypic variability in order to gain insights on the evolution of adaptively important features and the dynamics of the speciation process. We have discovered that A. lyrata is highly variable in resource allocation properties, and its extensive genomic resources make it uniquely valuable for studying these traits. In conjunction with these topics, I have been exploring novel statistical approaches for characterizing and predicting functions of quantitative trait loci (QTLs) that affect networks of traits such as life history trade-offs. I am a co-PI on an NSF-funded Math-Bio program at UNCG, in which undergraduates carry out research on topics integrating mathematics and biology.

TitleDateViewsBrief Description
Characters as Groups: A New Approach to Morphological Characters in Phylogenetic Analysis 2007 997 A new method for working with morphological characters is described and explored in experiments using human participants. The method uses direct comparison and sorting of images to produce hierarchical character-cladograms. A character-cladogram is a...
Complex Data Produce Better Characters 2004 603 Abstract: Two studies were conducted to explore the use of complex data in character description and hybrid identification. In order to determine if complex data allow the production of better characters, eight groups of plant systematists were given...
Detection of the Dinozoans Pfiesteria piscicida and P. shumwayae: A Review of Detection Methods and Geographic Distribution 2005 253 Molecular methods, including conventional PCR, real-time PCR, denaturing gradient gel electrophoresis, fluorescent fragment detection PCR, and fluorescent in situ hybridization, have all been developed for use in identifying and studying the distribu...
Effects of Causal Networks on the Structure and Stability of Resource Allocation Trait Correlations 2012 29 Discovering the mechanisms by which genetic variation influences phenotypes is integral to understanding life-history evolution. Models describing causal relationships among traits in a developmental hierarchy provide a functional basis for understan...
Game theoretic model of brood parasitism in a dung beetle Onthophagus Taurus 2009 39 We present a game theoretic model of brood parasitism in the dung beetle Onthophagus taurus. Female O. taurus engage in brood parasitism when they attack a brood ball made by another female, destroy the existing egg and place one of their own eggs to...
Genetic Basis of Local Adaptation and Flowering Time Variation in Arabidopsis lyrata 2013 75 Understanding how genetic variation at individual loci contributes to adaptation of populations to different local environments is an important topic in modern evolutionary biology. To date, most evidence has pointed to conditionally neutral quantita...
Local adaptation, phenotypic differentiation and hybrid fitness in diverged natural populations of Arabidopsis lyrata 2011 40 Selection for local adaptation results in genetic differentiation in ecologically important traits. In a perennial, outcrossing model plant Arabidopsis lyrata, several differentiated phenotypic traits contribute to local adaptation, as demonstrated b...
On Deterministic and Stochastic Models of Kleptoparasitism 2009 30 Kleptoparasitism, the stealing of food items, is a common biological phenomenon that has been studied mostly with the help of deterministic dynamics for infinite populations. The infinite population assumption takes the models far from the biological...
Partitioning adaptive differentiation across a patchy landscape: shade avoidance traits in Impatiens capensis 2008 60 Adaptation to different habitat types across a patchy landscape may either arise independently in each patch or occur due to repeated colonization of each patch by the same specialized genotype. We tested whether open- and closed-canopy forms of Impa...
Paths to Selection on Life History Loci in Different Natural Environments Across the Native Range of Arabidopsis thaliana 2013 44 Selection on quantitative trait loci (QTL) may vary among natural environments due to differences in the genetic architecture of traits, environment-specific allelic effects or changes in the direction and magnitude of selection on specific traits. T...
Taxonomy of Pfiesteria (Dinophyceae) 2006 668 The dinoflagellate species originally described as Pfiesteria shumwayae Glasgow et Burkholder, recently transferred to a new genus, Pseudopfiesteria Litaker et al., is reclassified into the redefined genus Pfiesteria Steidinger et Burkholder, as Pfie...
