We take an integrative approach to synthesize the ecology, physiology, and anatomy of plants in a comparative framework. We define our questions in the natural, changing environment and follow the answers to the molecular or ultra-structural level. A unifying theme of our studies is the question of how plants survive and thrive in their natural environment and what mechanisms are responsible for the acclimation and adaptation of plants to extreme environmental conditions. We identify the physiological and structural traits (and hopefully the associated genes) that protect plants, and particularly their ability to collect solar energy, perform photosynthesis, and distribute sugars throughout the plant. We compare these characteristics among plant species with contrasting growth patterns and acclimation strategies.     303-492-2880

As an aridlands ecologist, my research mission is to better understand the impacts of changing climate and land use on plant communities and soil resources in dryland ecosystems; research that crosses the boundaries of community, ecosystem, and landscape ecology. In my research program, I employ a variety of techniques in the fields of terrestrial plant ecology, soil biogeochemistry, and dendrochronology to address questions that not only further our knowledge of the structure and function of dryland ecosystems, but also address contemporary issues in sustainable restoration and management of these ecosystems.     303-492-8239

Social behavior in insects, kin recognition system of honey bees, nest defense in honey bees, and social biology of the giant tropical ant. Kin recognition studies are designed to examine the various factors--queen, workers, nesting material, and food--that go into recognition of nestmates, to demonstrate how these factors are integrated, their fitness outcomes, and their genetic basis. Nest defense is an interesting but relatively unexplored issue in honey bee biology. Studies have focused on the role of the guard bees in initiating defense responses. The giant tropical ant is a good model for the adaptation of a social insect to its environment. These studies, conducted in Costa Rica, have dealt with division of labor and recruitment     303-492-7687

As a biology education researcher, I investigate teaching and learning in biology with the aim of understanding what drives students to persist in biology research endeavors when they encounter challenges, setbacks, and ambiguity. As the fields of Ecology and Evolution continue to develop, the problems we tackle will become increasingly complex and require scientists to tackle increasingly challenging problems. To best instruct the next generation of scientists, we must understand why and how scientists make progress when challenges arise. My focus is on students' development motivation, grit, and resiliency in scientific research pursuits and how we, as instructors, can provide students with opportunities to develop these characteristics.

1) Plant Physiological Ecology: We integrate the ecology, physiology, and anatomy of plants. A unifying theme of our studies is the question of how plants survive and thrive in their natural environment and what mechanisms and genes are responsible for the acclimation and adaptation of plants to extreme environmental conditions. We compare and contrast these characteristics among plant species with different growth patterns and acclimation strategies. One focus of our work is the role of plant carotenoids. 2) Human diet-gene interactions: I sponsor undergraduate independent literature research in this area that frequently leads to publication of student-authored comprehensive reviews for audiences of clinicians, nutritionists and/or teachers.

My research is at the interface of quantitative genetics, population genomics and bioinformatics. I use these tools to address key ecological and evolutionary questions from multiple perspectives with a particular interest in domestication, adaptation, conservation, and speciation. Much of my work focuses on identifying the genetic changes that underlie the formation of new species or varieties, and more generally, the genetic basis of novel phenotypes. Currently, I am using sunflowers (Helianthus), mustard (Brassica) and chocolate (Theobroma) as model systems to pursue these research questions. In all three genera, I am examining how hybridization has shaped evolution, including the origin of new hybrid species, the breeding of modern lineages of domesticated plants, and the spread of invasive species.

Research interests My research program focuses on understanding drivers and processes of biodiversification. I'm especially interested in the way symbiotic interactions affect distribution, ecology and evolution of invertebrates. Our lab mainly uses diverse mollusk groups (clams, cockles, snails, etc.) to address research questions, but other systems are also being explored (protists, algae, crustaceans, etc.). We adopt a combination of phylogenetic comparative methods, geometric morphometrics, molecular evolution and bioinformatic approaches to study biodiversification at species, population, and genomic levels.

I am interested in the mechanisms producing and maintaining patterns of species distribution, abundance, and diversity. To address these processes, I consider three levels of ecological organization to be equally important: species-level autecology, population-level dynamics, and community-level processes and interactions. My research so far has highlighted small mammal range dynamics, abundance patterns across altitudinal ranges, and species richness patterns along latitudinal and elevational gradients. I particularly exploit mountain systems as natural experiments to look at how evolutionary history, ecological processes, and future climate change influence species populations. My overarching goal is to strive for quantitative, general theories applicable to both the advancement of ecology and the improvement of our conservation strategies. I use multiple tools at various spatial scales to address research questions, including field studies, synthesis of collection and historical data, comparative analyses, null models, GIS, and simulation modeling.     303-735-1016

My research interests combine the fields of parasitology, disease ecology, conservation biology, and herpetology. I work in a variety of places ranging from locally in Colorado to tropical rainforests. Many of my current projects involve fieldwork, labwork, meta-analyses, and applied conservation activities. Parasites and pathogens are ubiquitous and rival the diversity of free-living organisms on the planet. As global environments are changing rapidly, we are beginning to observe increases in infectious disease prevalence in both humans and wildlife. In order to understand patterns of emerging disease across the diverse spectrum of parasitic organisms, we must integrate several disciplines and ask questions at scales ranging from genetic and population levels to community and ecosystem levels. I am most interested in understanding the ways in which anthropogenic disturbances (e.g., land use, invasive species, wetland management) affect the parasites and pathogens of humans and wildlife. In the realm of conservation biology, the goal of my research is to identify key factors that lead to shifts in the abundance and distribution of parasites and pathogens in order to offer ecologically informed solutions to mitigate disease threats to vulnerable wildlife species.     303-492-7557

In my lab, we are interested in understanding the developmental evolution of our own subphylum, the vertebrates. To do this, we study developmental gene expression, regulation, and function in three model organisms; lamprey, amphioxus, and zebrafish. Lamprey, a jawless vertebrate, is the most basal vertebrate amenable to experimental manipulation at embryonic stages. Amphioxus is the most basal extant chordate and is thought to closely resemble the invertebrate ancestor of the vertebrates. Zebrafish, a teleost, is one of the most experimentally tractable vertebrate model systems. By comparing lamprey and amphioxus development with that of zebrafish, and other vertebrates like frog and salamander, we aim to reconstruct the genetic and developmental changes underlying the earliest events in vertebrate evolution.

My primary research interests focus on the evolutionary forces that influence genetic variation within and among populations. DNA sequences of mitochondrial, chloroplast, and nuclear genes, and electrophoretic variation of proteins are used to characterize variation in populations of plants and animals. Phylogeographic studies are used to describe patterns of variation and to make historical inferences about glacial refugia and routes of migration. I am particularly interested in three unique opportunities afforded by organellar genomes: 1) contrasting patterns of mtDNA and cpDNA in conifers; mtDNA is maternally inherited, and short dispersal, while cpDNA is paternally inherited and has potentially very long dispersal; 2) marine and freshwater have two mitochondrial systems, one with maternal inhertance, one with paternal inheritance; 3) mistletoes, which are parasitic on conifers, have stolen some genes from their hosts, and incorporated it into their chloroplast genomes.     303-492-8956

Ecological and Evolutionary Connections Between Animal Behavior and Population Biology. As a behavioral and evolutionary ecologist, I am fascinated by relationships among different scales of biological organization. Questions about individual variation (behavior, morphology, and physiology) and population patterns (social and genetic structure, population stability, species boundaries) are usually addressed in isolation from one another, but it is the relationship between these two levels that provides powerful predictive information about the causes and consequences of large scale patterns, such as the generation and loss of biodiversity. To make explicit links between behavioral ecology and population biology, I test theory-driven hypotheses related to both the function and proximate mechanisms that underlie individual behavior and use multi-level statistical models to explore the relationship between individual-level variation and larger-scale patterns within and among populations. I am currently most busy working on reproductive behavior and its consequences for population structure using the Hirundo rustica species complex as an interesting study system. This project is a large, international collaboration with many research opportunities for students at all stages of their careers.     303-735-1495

Evolutionary genetics, molecular phylogenetics, plant-pollinator interactions, comparative methods. My lab studies the evolution and genetics of floral diversification, with a focus on the tomato family, Solanaceae. We use molecular phylogenies and statistical comparative methods to infer the evolutionary history of floral traits and to test ecological factors that may have shaped their evolution. We also employ molecular, genetic, and biochemical approaches to understand the mechanisms underlying floral trait differences across species. Recent work has focused on the evolution of flower color, as this trait has a relatively simple genetic basis and is ecologically important. Results of our studies suggest that flower color changes can involve a range of genetic mechanisms (e.g., gene deletion, changes in gene expression, functional evolution) and may often be driven by competition for pollinators among sympatric species.

Plant Systematics, Tropical Botany, Lichenology, Biodiversity Inventory, Molecular Genetics and Evolution, Taxonomy, Nomenclature, Pollination Biology. As a biologist, I am broadly interested in the ecology and evolution of all life on Earth, particularly how natural selection and contingency have shaped the evolution of millions of “endless forms most beautiful”. As a natural historian, I am interested in patterns and trends that characterize the histories of these endless forms. Knowledge of evolutionary history is empowering, has real-world applications, and predictive potential. In attempt to understand the evolution of biodiversity and the ecological functions that biodiversity sustains, I focus on macroevolutionary approaches at or above the species level. Most of my research emphasizes the species-rich (>4,000 taxa) and morphologically diverse tropical plant family Acanthaceae. More recently, I have advanced research in lichenology, particularly here in the United States where amazingly, some 230 years after Bartram first traversed the Southeast, we still know incredibly little about these organisms from taxonomic and biogeographic perspectives. In addition to biodiversity research on Acanths and lichens, I have maintained a long-term interest in the flora of the tepui highlands of northern South America, where I have participated in or co-led numerous plant collecting expeditions to remote locations in effort to provide baseline plant biodiversity information for these highly endemic ecosystems.     303-492-2462
