My core personal research focuses on theoretical and conceptual issues at the population and community levels of ecological organization, and on the task of linking ecology with evolutionary biology. In addition to basic research, I am interested in bringing modern ecological theory to bear on significant applied problems, particularly in conservation biology. I have also carried out large-scale experiments on habitat fragmentation. My students include both theoreticians and empirical, experimental ecologists. I have historically collaborated with many faculty at a wide range of institutions, both inside and outside the USA. Web page with links to publications.

My background and interests are at the intersection of statistical methodology and environmental and ecological research. My current interests include development and application of statistical methods for spatial modeling of community structure and species abundances; accounting for uncertainty and sampling error in models of population dynamics; analyses when data are zero-inflated; developing sampling designs and estimators for rare and elusive species; linear and non-linear mixed models; hierarchical modeling; and sampling strategies for spatial data analysis. I collaborate and consult with scientists across many disciplines, including agriculture and natural resources, zoology, ecology, human nutrition, fisheries, and wildlife conservation.

I have spent my career on Chesapeake Bay creating quantitative methods to analyze networks of trophic transfers. I have developed methods that quantify indirect effects, trophic hierarchies, domains of recycling and whole system indexes of ecosystem organization and flexibility. In the process, I have reached the conclusion that the dynamics of ecosystems are hardly mechanical, but rather dual and dialectic-like. Consequently, I have proposed a perspective on nature that is predicated on processes rather than on objects and laws. My current interest is in promulgating the necessity of indeterminacy for ecosystem sustainability. In economic terms, the implication is that parallel, alternative currencies are likely required to impart sustainability to local and national economies.

I have worked at the Ecological Sciences Laboratory doing research on theoretical population biology since 2001. Publications are available through the link below, and include research on adaptation in source-sink systems (Holt et al. 2003, 2004a, 2004b, 2005; Holt and Barfield 2008, 2009b; Peniston et al. 2019), infectious disease ecology (Orive et al. 2005; Holt and Barfield 2006; Wayne et al. 2011; Smith et al. 2015; Barfield et al. 2015; Tuncer et al. 2016; Levi et al. 2016; Barfield et al. 2018), effects of temporal variation on populations (Holt and Barfield 2003; Holt et al. 2003, 2004b; Roy et al. 2005), evolution (Knight et al. 2008; Barfield et al. 2011), species ranges (Holt et al. in 2011; Holt and Barfield 2011; Filin et al. 2008), phenotypic plasticity (Scheiner et al. 2017, 2020), evolutionary rescue (Barfield and Holt 2016; Orive et al. 2017; Peniston et al. 2020), habitat connectivity (Fletcher et al. 2019), tropical forest diversity (Levi et al. 2019a, 2019b) and aquatic ecology (O’Brien et al. 2004, 2005; Mestre et al. 2019; Branco et al. 2020).

I am very broadly interested in ecology and evolution. My dissertation work focuses on how the interplay between ecological and evolutionary processes affects adaptation to harsh environments. The majority of my work involves the use of mathematical models or computer simulations, but I strive to combine theoretical predictions with experimental tests whenever possible. Thus, I am using experimental evolution in yeast systems to test some of my theoretical predictions regarding adaptation to harsh environments. I am a strong proponent of the importance of theoretical work in biology and I believe that theoretical and empirical biologists must work together in order to advance our understanding of natural systems.
