Research experience for undergraduates
Research Experience for Undergraduates in Environmental Sciences: Place Based Research and Training in Environmental Biology on the Colorado Plateau is an intensive 10-week research experience that take place each summer and is designed to introduce students to the world of scientific research. This Northern Arizona University (NAU) program is funded by the National Science Foundation Research Experiences for Undergraduates (REU) program.
Students are selected for the program on the basis of the following criteria: satisfactory performance in at least one science course, lack of access to research opportunities, attendance at a Tribal or community college, interest in pursuing a scientific career, alignment of student and mentor interests, match with program goals, and overall academic performance and potential.
The program begins with a weeklong course on the conduct of research in environmental sciences at the Merriam Powell Research Station, which is housed on the grounds of The Arboretum at Flagstaff. The arboretum is 5 miles from Flagstaff, Arizona, and surrounded by ponderosa pine forest.
Following this experience, students are ready to return to the NAU campus and spend nine weeks working with a faculty or graduate student mentor on an independent research project matching their interests.
The on-campus portion of the program includes: (1) seminars on career options, research skills development, and Native American and western science perspectives; (2) individual consultation on research paper and poster presentation development; and (3) social activities.
The program offers (1) a $525 per week stipend, (2) partial food and travel reimbursements, and (3) housing.
Field work at The Arboretum of Flagstaff Accordion Closed
During the first week of the program, participants conduct field work at The Arboretum at Flagstaff designed to give them hands-on experience conducting a scientific investigation. As a group, participants will develop hypotheses, design experiments, collect data, and report results. Although this field work experience may not directly relate to a participant’s individual research project, it serves as a “training ground” for the rigors of developing a hypothesis, gathering data, and communicating results.
Research experience Accordion Closed
During the final nine weeks of the program, participants have the opportunity to gain research experience. This portion of the program blends learning science and developing job skills. Participants will work under the guidance of a faculty mentor and experienced students. The goal is to expose program participants to the rigors of working in a research group in a format that teaches them the skills they will need to succeed. The daily schedule depends on the type of research project the student selects and may range from making observations using a microscope or mapping trees outdoors to analyzing data or writing up research results.
Tuesday evening class meetings Accordion Closed
The program includes a Tuesday evening class that primarily focuses on communicating research results. Participants will be given weekly writing assignments designed to help them develop their science writing skills. The class will focus on individual sections of a standard science paper beginning with the “Introduction” and moving through the “Methods,” “Results,” and “Discussion” sections. During the final two weeks of class, participants will learn the key elements required to create a good scientific research poster, including design, readability, and research content. Finally, guest speakers will talk about career options, scholarship opportunities, and graduate and undergraduate research.
Mentors & projects
Anita Antoninka, Forestry Accordion Closed
Dr. Antoninka works on the interactions between above and belowground communities and ecosystem function. In NAU’s Applied Soil Ecology Lab, Dr. Antoninka uses experiments to inform restoration of ecosystem function using plants, soils and soil biota. Lab members work across the west from deserts to forests, with topics focused on understanding the roles of soil organisms (e.g., biocrusts, mycorrhizal fungi, soil invertebrates) in restoring degraded landscapes. Biocrusts are communities of lichen, cyanobacteria and mosses that live in the top millimeters of the soil, performing every major ecosystem function. Mycorrhizal fungi are symbiotic fungi that associate with most plants, exchanging soil nutrients for fixed carbon. The focal soil invertebrates are nematodes, collembola and mites, all of which are incredibly important in nutrient cycling. The lab does experiments in the field, greenhouse and lab.
Rebecca Best, School of Earth Sustainability Accordion Closed
Dr. Best and students in her lab investigate the evolutionary origins of trait diversity and the consequences of that diversity for ecosystem function. Her research projects make use of the steep elevational gradients created by the Colorado Plateau, and focus on understanding (a) which aquatic species will persist in warmer waters with less predictable hydroperiods, and (b) which populations of riparian trees (e.g., from warmer vs. cooler locations) will continue to provide habitat structure. Graduate students and undergraduate students have been involved in both of these projects, with the opportunity to sample community composition in the field, quantify species and trait diversity in the lab, and learn through regular lab meetings how to organize, analyze, and present data that answer key questions.
Catherine Gehring and Amy Whipple, Biology Accordion Closed
Dr. Gehring and Dr. Whipple study plant- and soil-associated fungi in the context of environmental issues such as climate change, problematic non-native plant species such as cheatgrass and tamarisk, and altered fire regimes. Their research involves basic scientific studies of these environmental issues as well as the study of strategies for restoring damaged environments. New research projects will include plant and fungal reciprocal transplants along an elevational gradient. REU students have the opportunity to learn techniques used in both plant and fungal ecology including data collection associated with field experiments, set up and harvest of greenhouse experiments, and microscopic and molecular analyses of plant and soil associated fungi. An existing common garden provide ample opportunity for students to assess how plant traits and fungi vary across genotypes with measures that they can conduct over the summer.
Karen Haubensak, Biology Accordion Closed
Dr. Haubensak’s is a field ecologist who works at the interface of communities and ecosystems, examining plant-soil interactions in the context of restoration, biological invasions, and climate change. Her lab studies interactions and feedbacks among soil and plants to understand how terrestrial ecosystems respond to global change across a range of systems. REU students will have the opportunity to be involved in a sagebrush restoration project, examining how plant-plant interactions can change patterns of local adaptation, and challenging the notion that “local is best” in restoration. A second potential project involves the study of native pollinator-plant interactions in northern Arizona.
Richard Hofstetter, Forestry Accordion Closed
Dr. Hofstetter’s lab is currently working on a variety of projects related to forest entomology and forest health. Specific examples include the selection and performance of monarch butterflies on native milkweed species across an elevational gradient in Arizona, the role of climate change and temperature adaptions of fungi and mites associated with the bark pine beetles, and how fungal pathogens interact with bark beetle-fungal associates within trees. Other projects in the Hofstetter lab include study of the presence of endophytes in ponderosa pine phloem and how this may affect tree survival and bark beetle colonization success of trees across forest stands, the role that insects play in restoring ponderosa forests after fire, and the basic biology of native harvester ants and how their foraging choices affect their stomach microbial community.
Liza Holeski, Biology Accordion Closed
Dr. Holeski is a plant evolutionary geneticist and ecologist. Her research focuses on plant adaptation to climate change and plant-herbivore interactions. REU students will work with Dr. Holeski on a project studying the environmental and genetic mechanisms underlying natural selection and adaptation in monkeyflowers, a model plant species native to the Colorado Plateau and the western United States. Students will investigate the relative roles that genetic variation and environmental variation in biotic and abiotic factors such as herbivory, water availability, and temperature play in adaptation.
Jani Ingram, Chemistry Accordion Closed
Dr. Ingram’s project is a collaboration between Northern Arizona University and Diné College that focuses on an issue of interest to the Navajo people; specifically contamination of their traditional food staple, mutton. Previous work in the Ingram lab has shown that the soil and plants in the mining areas have elevated levels of uranium compared to the non-mining areas studied. The proposed project would expand on preliminary work investigating elevated levels of uranium in sheep grazing on and around abandoned mines located on the Navajo Reservation. The field sites include mining areas in the southwestern and central portions of the Navajo Reservation. The results will be provided to the communities and Navajo tribal leaders.
Tom Kolb, Forestry Accordion Closed
Climate change is increasing aridity and deforestation. Arid-adapted trees are needed for reforestation projects to ameliorate negative impacts of increasing aridity on forest production and services. Little is known about tree genetic adaptation to aridity in regions highly vulnerable to climate change such as the southwest U.S. Summer REU students will measure traits of trees identified as more and less arid adapted to help us understand the mechanisms of aridity adaptation.
Matthew O’Neill, Biology Accordion Closed
Dr. O’Neill is a fishery biologist with the Coconino National Forest, US Forest Service. His research involves management practices for fish habitat and populations in the Coconino National Forest, including many threatened and endangered aquatic species. Dr. O’Neill has been active in multiple undergraduate research programs in the past, including mentoring of students through NAU’s Initiative for Maximizing Student Diversity and the NAU Undergraduate Research Mentoring program. Prospective REU student research might include experiments that assess optimal native fish habitat characteristics, or monitoring fish populations over time, and in relation to abiotic and biotic environmental alterations.
Bret Pasch, Biology Accordion Closed
Dr. Pasch studies the physiology, ecology, and evolution of acoustic communication systems in rodents of the Colorado Plateau and desert southwest. Of particular interest is the role of vocal signals in mediating mate recognition and reproductive isolation among ecologically similar species, and the evolutionary relationship between social organization and physiological adaptions of senders and receivers. Students will participate in ecological and behavioral studies, working with Dr. Pasch to develop and test independent hypotheses.
