Faculty Detail

Paul Brown   Paul Brown

My research is conducted in the broad area of aquaculture with a focus on nutrition. Examples of my current research projects include (1) the use of soybeans in diets fed to trout, salmon and shrimp, (2) evaluation of fish in Advanced Life Support Systems, (3) the development of fish meal-free diets for yellow perch and hybrid striped bass, and (4) the integration of proteomics in aquaculture research. Preliminary data has been collected on the effects of increasing carbon dioxide concentrations in aquatic habitats and the effects on food chain dynamics. Model species used in the past 15 years include zebra fish, Atlantic salmon, coho salmon, rainbow trout, brook trout, Nile tilapia, walleye, hybrid striped bass, largemouth bass, yellow perch, bluegill, crappie, freshwater shrimp, marine shrimp, American lobsters, spiny lobsters, and 4 species of crayfish.

Andrew Dewoody   Andrew DeWoody

My lab group uses molecular markers to study otherwise cryptic aspects of organismal biology. For example, we are interested in how natural and sexual selection act in concert to maintain major histocompatibility complex (MHC) variation in natural populations. Molecules also can be used to monitor vertebrate animals, and we have used gender-specific markers and microsatellite DNA to track population turnover of endangered species. In addition to our population and conservation work, we are interested in molecular processes such as the transposition of genes from cytoplasmic genomes to the nucleus. Such transpositions are important because 1) they probably serve as a source for novel genes and 2) they are an excellent model for the transgene delivery systems used in human gene therapy.

  Jeff Dukes

Jeff Dukes and his research group seek to address environmental challenges through ecological research and outreach. Their research currently focuses on three themes: understanding how ecosystems respond to climate and atmospheric change, understanding and minimizing the impacts of invasive species on ecosystems, and exploring the ecological consequences of switching our energy supply from fossil fuels to biofuels. Dukes has a particular interest in understanding how changes in climate and the atmosphere will affect the success and impact of invasive species.
Dukes directs the Boston-Area Climate Experiment (BACE), which characterizes ecosystem responses to gradients of climate change. Will the processes and properties of communities and ecosystems respond linearly to changes in temperature, or are there important threshold temperatures that could be reached? To what extent does an ecosystem's response to warming depend on precipitation patterns? The BACE tests these questions in a New England old-field ecosystem. Researchers are measuring responses of several variables, including growth of wildflowers, grasses, and tree seedlings.
A new collaborative project with researchers at UMass Boston examines how plants control the composition of microbial communities surrounding roots, and how these microbial communities mediate competition among plants.
Dukes's past research has shown that some terrestrial ecosystems may slow climate change less than previously assumed, that some biodiversity losses may affect the success and impact of invasive species, that about 100 tons of ancient plant matter were required to produce a gallon of gasoline, and that replacing fossil fuels with modern plant matter would demand more than a quarter of all plant growth on land.

Jeff Dukes has appointments in Purdue's Departments of Forestry and Natural Resources and Biological Sciences, and is involved in the Purdue Climate Change Research Center. He moved to Purdue in August 2008 from the Department of Biology at the University of Massachusetts Boston, where he now holds an adjunct appointment. For more information, and for publications, visit Prof. Dukes's personal web page, or web pages for the Dukes lab and the Boston-Area Climate Experiment. If you are interested in joining the Dukes lab, please contact Prof. Dukes by email. Prospective graduate students can apply through the Department of Forestry and Natural Resources, the Department of Biological Sciences, the Ecological Sciences and Engineering (ESE) Program, and other avenues. Some of these avenues offer excellent competitive fellowships.

  Barney Dunning

I am interested in understanding how natural populations and communities respond to changes in the distribution and quality of habitats across complex landscapes, especially changes associated with human land-use. Most recently, my research group has used restoration ecology as a model system for studying the response of native organisms to changes in habitat distributions at the landscape scale. We have looked at the response of breeding amphibians, migratory waterfowl and shorebirds, and grassland birds and mammals to large-scale restoration of prairie and wetlands in landscapes dominated by modern agriculture. The interdisciplinary nature of our research is illustrated by a landscape-scale restoration of prairie and wetlands project at Kankakee Sands in northwest Indiana. Funded by The Nature Conservancy, Kankakee Sands is the largest private grassland restoration east of the Mississippi River. We are studying the effect of restoration on grassland and wetland organisms as part of a larger effort involving 8 colleges and universities in Indiana and Illinois, members of which are examining the genetic, population and community consequences of active restoration techniques, with projects focused on plants, insects, amphibians, reptiles and birds.

  Nancy C. Emery

I am interested in the evolution of the ecological niche, and how ecological processes shape the evolutionary trajectories of populations and species.  The distribution of a species is largely a reflection of its ecological niche, and a major part of my research aims to understand the ecological and evolutionary processes that shape the distribution patterns that we observe in natural populations. My research integrates community ecology, population biology, and phylogenetics; I use field experiments, molecular methods, anatomical techniques, and comparative methods to address a variety of questions about the evolution of the ecological niche in plant populations and species.  I have worked in a variety of plant community types, ranging from salt marshes to serpentine grasslands, and I am particularly attracted to studying plant species that inhabit ecologically stressful or marginal habitats.  In these systems, I address questions such as “What ecological and genetic factors restrict this species to this habitat type?” “What are the patterns of adaptation across the distribution of this population (or species)?” and “How do various ecological factors influence patterns of gene flow across the species’ distribution, and what are the evolutionary consequences of that gene flow?”

  Estaban Fernandez-Juricic

My research is question-driven, and is focused on behavioral ecology, visual ecology, and conservation biology. I answer my questions in a comprehensive manner, using a combination of empirical, theoretical, and comparative approaches. My model species are usually birds, but I have also worked with mammals, amphibians, insects, and fish. I am interested in two research areas at the moment:  Behavioral ecology and sensory ecology_:_ the role of ecological factors in the evolution of avian visual systems in species with different degrees of sociality.  Conservation biology: human-wildlife interactions in urbanized landscapes, protected areas, and airports.  My lab combines techniques to characterize different properties of the avian visual system (visual fields, retinal topography, visual acuity, color vision) with behavioral experiments in controlled conditions (indoors and outdoors) and field observations.

  Jennifer L. Freeman

My research interests are in molecular and environmental toxicology, cytogenetics, and genomics. Current research efforts in the Freeman laboratory are focused on investigating the adverse effects of chemical environmental stressors on human and environmental health using the zebrafish model system. Ongoing research projects in the Freeman laboratory are defining the influence of environmental stressors on genomic instability and carcinogenicity, investigating the role of structural genetic variation in response to exposure to environmental stressors, and identifying the role of developmental exposure to environmental stressors in the onset of neurological disorders. Specific environmental stressors of interest include pesticides and metals.

  Kevin Gibson

The principal tenet of integrated weed management is that, by presenting weeds with a more complex pattern of management practices, weed populations can be decreased, resistance to management tactics delayed and herbicide inputs reduced. The complexity of integrated weed management systems requires that work be conducted from a whole-systems perspective. However most research conducted on weed management occurs at organizational levels below that of whole-systems and so is often of limited value to farmers and resource managers interested in adopting new approaches to weed management. The primary goal of my research program is to develop a better understanding of the relationships between management systems and the distribution and abundance of weed species within agricultural and forest ecosystems. We have ongoing collaborative projects in four main areas: 1) weed management systems in tomato, 2) biology and management of glyphosate-resistant horseweed site-specific weed management, 3) the susceptibility of forests to plant invasion and 4) the use of remote sensing to explore relationships between the spatial distribution of weeds and management systems. In addition to these major projects, we also have projects addressing garlic mustard population dynamics, and the role of seed predation in tomato cropping systems.

  Mathew Ginzel

We are broadly interested in the chemically-mediated host colonization and mating behaviors of wood-boring beetles. North American hardwood forests are increasingly threatened by a litany of indigenous and invasive wood-boring insect pests. In fact, wood-boring beetles are among the most economically important pests of woody plants in natural and managed systems. Unfortunately, the destructive nature of many wood-boring insects is exacerbated by difficulty in controlling their populations. Because they spend the majority of their lives concealed beneath the bark of trees, these insects are physically protected from sprayed pesticides. The long term goal of my research program is to develop effective pest management tactics targeting the chemically-mediated mating system of the beetles. This information will be useful in establishing effective management programs, such as by optimizing survey strategies, developing arboricultural techniques to bolster resistance, and improving methods for detecting invasive species to improve the health, quality, and productivity of North American hardwood forests.

  Jeff Holland

My research program examines the impacts of land use at different spatial scales on insect populations and movements, and on overall arthropod biodiversity. A main goal of my research group is to understand how to best configure landscapes at a range of spatial scales to balance human land use needs with the conservation of biodiversity. Understanding how to encourage native biodiversity while limiting the spread of invasive exotic species is another major goal. Most of the work done in my lab uses extensive field work on various arthropod species, and digital maps and air photographs in geographical information systems (GIS) to measure land use characteristics.

I am interested in environmental questions at the interface between applied and basic ecology. To address such questions I use an adaptive research approach and employ a variety of research methods (e.g., field sampling, controlled experiments, statistical analysis, simulation modeling). The focus of my research is fish and fisheries ecology in the Laurentian Great Lakes. However, I also study lower trophic level organisms and both smaller freshwater and larger marine ecosystems

My general research interests center on the interaction between the two components of sexual selection (mate choice and mate competition), and how these processes influence mating success and patterns of sexual dimorphism. I currently am working on 4 projects: 1) acoustic playback experiments on male and female American toads to determine how male-male interactions influence male vocal behavior and how females use male vocalizations in their choice of mates; 2) the ontogeny of a sexual dimorphism in tiger salamanders; 3) the reproductive biology of a naturally occurring, triploid, all female species of salamander; and 4) how the accidental or intentional release of genetically modified organisms could influence natural populations; in this research I use three fish species, Japanese medaka, Nile tilapia, and zebrafish.

Mike's research focuses on the interactions between disturbance and abiotic factors and their synergistic influence on ecosystem structure and function. Specifically, he is interested in how human-induced changes to native disturbance regimes and species pools have altered the distributions, interactions, and coexistence of species through changes in ecological processes. His current research projects include exotic disease effects on nutrient cycling, invasion dynamics of exotic plants following the restoration of native disturbance regimes, long-term response of understory plant communities to chronic herbivory, and acid deposition and soil chemistry as drivers of species distribution in high-elevation spruce-fir forests.

  Morry Levy

With several international collaborators, we focus our research on the evolutionary genetics of a major crop pathogen, the rice blast fungus. Using DNA fingerprinting and other techniques, we've shown that rice blast populations throughout the world are each composed of a small number of distinct genetic families with limited pathogenic specificities. We've used this information to design strategies for durable resistance breeding that have proven successful in both the Americas and Asia. Deciphering how the fungus has evolved its specificities is our next goal.

  Jeff Lucas

My research program has focused on two general areas: the dynamics of animal decision-making and (more recently) animal communication. Much of the work in behavioral ecology is based on the fundamental assumption that the evolution of behavior reflects a balance between the costs and benefits associated with any given behavior pattern; thus a study of costs and benefits should provide an understanding of the factors that regulate the evolution of that behavior. It is not a trivial matter, however, simply to enumerate all relevant costs and benefits of any behavior, better yet to understand how those costs and benefits combine to regulate the evolution of behavior. To this end, I have been developing models of animal decision-making processes and developing tests of the predictions of these models. We have modeled a fairly wide range of phenomena, from sperm allocation strategies in salamanders to lek attendance in sage grouse. Our tests of dynamic models have primarily focused on energy regulation and caching patterns in Carolina chickadee. My interest in animal communication began with an extension of my research on the effect of physiological state on foraging decisions, and has since become more focused on both the ecological aspects of communication and on mechanisms of signal reception. Carolina chickadees are an interesting model system for studies of communication because they are an example of a species whose vocal repertoire has a number of characteristics of a true language.

  Dennis Minchella

Drawing upon both molecular and experimental field approaches, research in my laboratory focuses on the population biology, evolution, and genetics of host-parasite interactions. The research program encompasses both host-parasite coevolution and the genetic structure of parasite populations. Variation in host-life history patterns may be a result of a parasite adaptation, a host adaptation or a non-adaptive side effect of the interaction. Genetic heterogeneity of hosts and parasites fuels the coevolutionary "arms race" leading to an array of varied outcomes. Using snail-trematode systems as models, we have demonstrated that hosts potentially modify the outcome of parasitic infection either by resisting infection (immunity) or varying other life-history parameters. Combinations of field observation and laboratory experimentation are utilized to better understand the interaction between host-parasite coevolution and variations in host-life-history. Interactions between trematodes and their snail hosts influence parasite genetic systems and impact on disease epidemiology in humans. Microsatellite DNA sequences are used to quantify host and parasite genetic heterogeneity in natural populations across space and through time. Currently, we are combining mathematical models and empirical field studies to assess and predict the genetic population structure of human schistosomes. Results will yield evolutionary insights into the epidemiological process, help identify genetic consequences of control strategies, and complement concurrent immuno-epidemiology studies of humans in endemic Brazilian communities.

  Bill Muir

My research program encompasses quantitative genetics from new theoretical developments to direct applications and molecular genetics. My quantitative genetics research is divided into two areas: behavioral genomics and biotechnology risk assessment. In behavior genetics we are using a new method of selection, termed “group selection” to overcome problems of competition and cannibalism. Competition and cannibalism are one of the greatest problems in commercial aquaculture. We found that finfish will responded to group selection but not to classical individual selection, similar to many fish species such as carp. We see this as the solution to domesticating problem species, such as walleye and lobster, and improving production of shrimp. Our research suggest that through group selection, cannibalism, aggression, and territorialism may be reduced or eliminated. In biotechnology risk assessment associated with transgenic fish, our model showed that a transgene can increase in a population in several ways. Results also showed that the interaction of fitness component effects could offset each other. Relative to risk, the model showed that if sexual selection favors transgenic fish, while viability selection favors non-transgenic fish, a potentially dangerous situation can develop whereby the transgene is driven into the population by male mating advantages, but average fitness of the population decreases and causes population extinction. Results of our study show which parameters are critical for risk assessment and which characteristics need to be measured in commercial programs before any release is attempted. Some combinations of fitness components have a high potential to increase risk. We also examined development of phytase transgenic fish for enhancement of the environment and profitability of farming. Phytate is the major phosphorus storage form in plant seeds. The main objective of the research was to demonstrate that fish transgenic for the phytase gene can directly utilize phytate, eliminating phosphorous pollution from aquaculture operations.

  Krista Nichols

My research interests lie at the intersection of evolution, genetics, physiology, and ecology. Currently, my research aims to understand the genetic basis and evolutionary history of variable life history traits, physiologies, adaptations, and ecological specializations in fishes. I use quantitative genetic and physiological tools in analyses aimed at identifying the genetic architecture of divergent traits. Using molecular and expression techniques, further dissection of genome regions and candidate genes for these traits is achieved. With these combined approaches, we are beginning to understand the number, identity, and expression of genes underlying the standing phenotypic variability among and within fish populations. With this information, we begin to test hypotheses about the evolutionary forces that have shaped this variation.

I am interested in developing spatial simulation models that examine the impact of human behavior on environmental quality and ecological integrity. A major theme of my research is to apply the latest information technologies, such as neural nets, agent-based models, and geographic information systems, to understand the consequences of land use/land cover change. Most of my effort involves coupling land use/cover change models to other environmental or economic models and developing assessment approaches quantifying ecological integrity.

  Kerry Rabenold

My research interests are in ecology generally, particularly at the levels of individual behavior, population dynamics, community structure, and biogeography, and particularly in conservation biology of tropical systems. Recent work has addressed the evolution of cooperative social systems in birds, the implications of dispersal patterns for population viability and genetics, resilience of forest bird communities to anthropogenic disruption, spatial organization of species diversity in tropical landscapes, and the conservation implications of correlations between local rarity and geographic range size in endemic species. In our most recent work in Costa Rica, we have combined field censuses of montane rainforest birds, GIS-based modeling of their habitat distributions, and geographic range information to explore the linkages among ecological specialization in these diverse communities, rapid change in species composition along environmental gradients ("beta diversity"), the tendency for endemic species to be rare at all scales, and the sufficiency of protected areas in systems where endemics are concentrated at higher elevations and in life zones both important to agriculture and vulnerable to climate change. Through collaborations we are also exploring the correspondence of spatial and temporal change in plant and animal communities and the genetic implications of increasingly fragmented distributions.

I am a biological anthropologist who studies gorilla behavioral ecology and primate conservation in sub-Saharan Africa. I am currently working on a collaborative project on the impacts of multiple human disturbances on 5 groups of mammals (primates, carnivores, ungulates, rodents and shrews) in the Congo Basin. This research addresses both wildlife and human dimensions of ecosystem change. It contributes to our understanding of vulnerable ape populations, the ungulates and others which constitute the protein base for the region, changing subsistence patterns, hunting and logging practices, human-animal conflict, the bushmeat trade, and forest fragmentation. We are analyzing 20 years of wildlife census and ethnographic data to contribute to improvements in international approaches to conservation management. We also are involved with efforts to improve our understanding of the molecular genetics and conservation of Central African primate populations and the impacts of ecotourism on gorillas in East and Central Africa.

  Cliff Sadof

I study the ecology and biology of scale insects and mealybugs to determine how the quality of host plants, habitats and landscapes contribute to pest outbreaks. At the primary trophic level, I am interested in how plant growth and physiology alters the susceptibility of plants to arthropod herbivory. At the second trophic level I am interested in how plant shape and growth affects the ability of natural enemies to regulate herbivorous arthropods. These studies can involve the host plant itself, or plants in the landscape that can provide the food and shelter resources to parasitic and predaceous arthropods that can act to reduce numbers of arthropod pests. On a larger landscape scale, I am interested in looking at how the proximity of plants to factors such as ant colonies, forests, meadows, and buildings alter herbivore and natural enemy population dynamics. I am interested in developing novel outreach programs for managing exotic and native pests of trees and ornamental plants with fewer pesticide inputs. I am also interested in working with regulatory agencies to develop programs that improve the detection of exotic wood borers on solid wood packing material in warehouses. Off-shore, I am interested in working with ornamental producers to reduce the abundance of pests in products designated for export. Currently I am developing a project in Costa Rica where I will be working with ornamental growers to help them develop tactics that reduce the abundance of scale insects and mealybugs on export crops.

My overall interests include the applications of remote sensing, geographic information systems (GIS), forest simulations models, and forestry decision support systems in sustainable management of forest resources. I have worked to accurately map land use and land cover types at local and regional scales with multi-spectral data, GIS protocols and interfaces for straight-forward and consistent ecological landtype mapping, simulate and forecast forest development under natural and human-induced environmental conditions such as climate change, and convert state-of-the-art geospatial and modeling techniques into operational interfaces as tools for forest ecosystem management. A unique expertise in my research lab is the development and fine-tuning of individual-based forest models and assessment of the effects of climate change on forest structure with forest gap models. We are also interested in the impacts of forest policy and forestry practice on biodiversity conservation, timber supply, and soil/water protection in the temperate zone of Earth.

"Molecular Ecology" describes the emerging application of molecular techniques to problems in ecology and evolutionary biology. Our program in this area focuses on mammalian social behavior, population dynamics and genetics. Students combine molecular genetics with traditional field observations in studying gorillas and forest monkeys in Central and East Africa, carnivores in Africa and Arizona, and small mammals in the southwestern US and in Indiana. We're particularly interested in developing DNA "fingerprinting" techniques that will let us monitor attributes of wild animal populations relevant to conservation. This work is highly collaborative, involving cross-school initiatives with faculty in the schools of Agriculture (Forestry & Natural Resources) and Liberal Arts (Anthropology). We also collaborate with biologists in Canada, Europe and Africa, where we are pursuing a long-term project in primate conservation.

  Harmon Weeks

My research focus is in two general areas: avian breeding ecology and mammalian mineral nutrition. Avian work focuses on the impact of anthropogenic habitat and landscape features on avian behavior and productivity. Influences of habitat fragmentation, edge, and residential and agricultural development may positively or negatively influence populations/communities of birds. I evaluate such influences, in an attempt to identify and quantify factors critical to conservation efforts. Wild herbivorous mammalian species are in a delicate balance with sodium and other minerals available in the ecosystem. Deficiencies greatly impact behavior, morphology, physiology, and population dynamics of these species, and management of sodium supply has very real potential to modify many processes. I examine community and species-specific adaptations and responses to the dynamics of sodium availability.

  Pat Zollner

My research interests are in integrating behavioral ecology and landscape ecology. Thus my work focuses on understanding of how changes in landscape composition and structure caused by resource management affect wildlife species of conservation concern. I combine innovative empirical studies that quantify dispersal-related behaviors with theoretical studies developing spatially explicit simulation models. This allows the implications of human activity on animal behavior to be explored across alternative future scenarios (e.g., forest management). My research focuses on how several mammalian model species move through and use landscapes however I also have several relevant studies on birds and I am interested in initiating related research on reptiles and amphibians. Thus, the overall goal of my research is to investigate how wildlife species of conservation concern are impacted by landscape patterns of habitat arising from human activities such as forest management, and fragmentation from agriculture.
