HWS SUMMER RESEARCH OPPORTUNITIES 2017

Biology

Conservation Genetics of Pocket Gophers in the Midwestern U.S.

Faculty Contact: Professor Bradley Cosentino ()

Project Description: The plains pocket gopher (Geomys bursarius) is a burrowing mammal found across the Great Plains of the U.S. Because of its limited dispersal ability, there are several disjunct populations across the geographic range that may benefit from conservation efforts. Subspecies and distinct populations are eligible for protection under state and federal law, but population genetic analysis is needed to help identify subspecies and population boundaries. The student will test a suite of genetic markers to determine suitability for population genetic analysis of G. bursarius. This is a laboratory-based project, and the student will gain experience with DNA extraction, PCR amplification, and genotyping.

Student Qualifications: Background in biology and completion of one of the following courses: Biostatistics, Genetics, Population Genetics, Ecology, Behavioral Ecology. Strong work ethic and interests in wildlife conservation and genetics are essential. Must have a driver’s license.

Dates: May 22 – July 21 (both dates tentative)

Examining Responses of Biodiversity to Grassland Restoration in the Chihuahuan Desert, New Mexico

Faculty Contact: Professor Bradley Cosentino ()

Project Description: Shrub invasion has led to the loss of grassland habitats in arid landscapes throughout the world. This project will involve investigating how biodiversity and ecosystem services respond to attempts to restore desert grasslands in the Chihuahuan Desert of southern New Mexico. Students will conduct surveys for various types of wildlife (e.g., lizards, rodents, songbirds) to help understand how wildlife abundance depends on the amount and spatial configuration of restored habitat. Students will also participate in experimental studies to better understand dispersal constraints affecting site colonization by banner-tailed kangaroo rats, a keystone species. These positions require field work to be conducted in New Mexico. Travel and housing costs are covered.

Student Qualifications: Strong work ethic and interests in wildlife conservation and ecology are essential. Must be enthusiastic about conducting field work in rural, arid landscapes. Must have a driver’s license.

Dates: TBD (10 weeks)

Effects of Forest Fragmentation on Behavior of Woodland Salamanders

Faculty Contact: Bradley Cosentino () and Professor David Droney ()

Project Description: In landscapes of the Northeast, timber harvest and subsequent reforestation has created extensive variation in the age and quality of forest patches. This project builds off our previous studies exploring how forest change in the Finger lakes has affected movement behavior of red-backed salamanders (Plethodon cinereus). The students will conduct a field experiment to test whether colonization of artificial forest plots depends on individual differences in movement behavior. Students will gain experience with field experience with field sampling, behavioral observations in the laboratory, and animal care. See our recent paper in Animal Behavior for more background information: goo.gl/5TEilw

Student Qualifications: Background in biology. Strong work ethic and interests in wildlife conservation and behavior are essential. Must have a driver’s license.

Dates: May 22 – July 28 (both dates are tentative)

Audubon Seabird Restoration Internship

Faculty Contact: Professor Mark Deutschlander ()

Project Description:Hobart and William Smith students have the unique opportunity to participate in the internationally-recognized Audubon Seabird Restoration Program (a.k.a. “Project Puffin”). This internship is a paid position directly through the Audubon Society (final selection of an intern will be made by Audubon biologist Stephen Kress).

Position Description: Audubon’s Seabird Restoration Program operates seven island field stations along the Maine coast as critical seabird nesting sanctuaries. Research Interns will work under the direction of the Island Supervisor, participating in all aspects of seabird research, monitoring, and management that take place at the field station. The majority of research projects focus on studying the nesting success and foods fed to seabird (tern and alcid) chicks, with most work focusing on terns. Work includes, but is not limited to: conducting population censuses, monitoring productivity and chick growth; conducting seabird diet studies; banding and resighting birds; removing invasive vegetation; educating island visitors; and assisting with predator management.

Research Interns will live on island (a single island or group of islands) for the duration of the field season. Interns assigned to inshore islands will have occasional trips to the mainland for logistics and resupplying the field camp, returning to the islands to work and sleep. On offshore islands, food, supplies, and mail are delivered approximately every 2 weeks. In a seabird colony, the birds are loud, and the terns defend their nests by dive-bombing anyone moving through the colony. Living conditions on the islands are primitive. A cabin or wall tent serves as the base of field operations, and field team members sleep in their own tents (wooden tent platforms provided). Island field stations have limited electricity (solar panels power research needs), propane stoves, composting toilets, and no running water (rainwater is collected for washing; drinking water is brought from the mainland). Communications with the mainland are via cell or VOIP phone, depending on location, with VHF radios available as a back-up mode of communication. There is no internet access. Cooking, cleaning, and camp maintenance duties are shared by all island team members. Food is provided.

Applicants should have a strong background/interest in field biology and/or environmental science and conservation biology. Preference will be given to applicants who have completed multiple courses in biology and/or environmental studies.THIS INTERNSHIP IS AVAILABLE TO GRADUATING SENIORS AS WELL AS OTHER STUDENTS

Student Qualifications: SO, JR, SR. Preference given to students considering careers in conservation and/or environmental science.

Dates: Start date: ~ May 26; End date: TBD, but between July 22 and August 15

Investigating the Evolutionary History of Milkweeds in North America Using Genomic Tools

Faculty Contact: Professor Shannon Straub ()

Project Description: Milkweeds (Asclepias) are a recent rapid evolutionary radiation that has resulted in diversification of more than 100 species in North America. These species have served as models for plant reproduction and plant defense, most notably in the study of coevolution with monarch butterflies (Danaus plexippus), which are able to sequester the cardenolide toxins produced by the plants for their own defense. Resolving the evolutionary relationships in this rapid radiation is necessary for understanding the evolution of defense traits, and other morphological traits, such as flower structure, but has been difficult using traditional approaches. This study will investigate the genomic evidence for the evolutionary relationships among Asclepias species through simultaneous targeted sequencing of 700+ nuclear genes and whole chloroplast genomes from multiple populations per species followed by phylogenomic analyses. Students will work in teams to acquire lab skills, including DNA extraction and Illumina DNA sequencing, and gain bioinformatics and data analysis experience. Individual student projects may focus on questions involving phylogenetic relationships and morphological character evolution, molecular or genome evolution, or species delimitation as mutually agreed upon by student and mentor at the beginning of the summer.

Student Qualifications: BIOL 167 and one additional BIOL course, preferably BIOL 220 or BIOL 228.

Dates: May 31 - August 8

Phylogenomics of the APSA Clade of Apocynaceae (Milkweeds and Dogbanes)

Faculty Contact: Professor Shannon Straub ()

Project Description: Milkweeds and dogbanes (Apocynaceae) comprise the 10th largest family of flowering plants, and are best known for their secondary chemistry that mediates interactions with insect herbivores. Multiple insect lineages have evolved mechanisms to tolerate toxins produced by the plants, such as pyrrolizidine alkaloids, and sequester them to make themselves unpalatable to predators, and in the case of milkweed and clearwing butterflies (Danainae), use them to synthesize mating pheromones. The APSA clade of Apocynaceae contains four subfamilies: Apocynoideae, Periplocoideae, Secamonoideae, and Asclepiadoideae. Resolution of the evolutionary relationships of the subfamilies and species in the clade is required to understand the evolution of the biochemical pathways for secondary metabolite production. The evolutionary relationships among the species in the APSA clade will be investigated through simultaneous targeted sequencing of ca. 800 nuclear genes and whole chloroplast genomes followed by phylogenomic analyses. Students will work in teams to acquire lab skills, including DNA extraction and Illumina DNA sequencing, and gain bioinformatics and data analysis experience. Individual student research questions may address phylogenetic relationships among species in APSA tribes or subtribes, including exploring conflict between the results given by nuclear genes vs. whole chloroplast genomes and the use of the genetic data to resolve outstanding taxonomic questions. Another student research avenue within the scope of this project would be to explore the molecular evolution of particular nuclear genes or whole chloroplast genomes in various groups within the APSA lineage.

Student Qualifications: BIOL 167 and one additional BIOL course, preferably BIOL 220 or BIOL 228.

Dates: May 31 - August 8

Chemistry

Endocrine Disruption in Minnows in the Finger Lakes Region

Faculty Contact: Professor Walter Bowyer ()

Project Description: A wide range of pollutants are similar enough to estrogen to disrupt normal endocrine activity and can even stimulate egg production in the gonads of male fish (testis-ova). This has been demonstrated to occur in many streams and lakes all over Europe and North America, but surprisingly no one has investigated the phenomenon in the waters of the Finger Lakes region. We are pursuing a project in which we use Blacknose Dace (Rhinichthys atratulus, a minnow abundant in Finger Lakes) as a bioassay preparatory to designing strategies for chemical analysis of the water for xenoestrogens.

Student Qualifications: At least two semesters of college chemistry.

Dates: June 12 – August 8

Synthesis and Characterization of Molecular Wire Candidates

Faculty Contact: Professor Christine de Denus ()

Studying Enzyme Kinetics in a Crowded Environment Like the Cell

Faculty Contact: Professor Kristin Slade ()

Project Description: The research aims to investigate how the densely packed interior of cells affects the rate of enzyme-catalyzed reactions and the ability of these enzymes to bind their substrates. Due to the lack of quantitative cellular methods, we will create controlled in vitro environments containing crowding agents that mimic intracellular conditions.

Student Qualifications: Open to curious students with at least one year of chemistry by the summer of 2017.

Dates: May 15 (tentative) – July 7

Cutting the Protein: Investigating the Interactions that Facilitate Membrane Biofouling in Desalination

Faculty Contact: Professor Elana Stennett ()

Project Description: The need for sustainable and affordable water purification techniques has risen with the rise in water scarcity. Desalination, purifying ocean water by removing dissolved materials via reverse osmosis, is increasingly being utilized due to the simplicity of the technique. Reverse osmosis uses high pressures to push “dirty” water through a semi-permeable membrane so that pure water emerges and the dissolved material is left behind. However, the membrane can quickly become blocked, called fouling, which requires replacing or cleaning the membrane, neither of which are effective. Understanding the interactions and mechanisms behind biofouling (fouling due to biological molecules like proteins) is an active area of research. The goal of this project is to probe the interactions that facilitate biofouling using established and novel spectroscopic techniques on a model system of peptides. This project involves not only simulating desalination conditions but also synthesizing a variety of proteins to will be studied. Fluorescence spectroscopy will be used to analyze the interactions between peptides and membranes that result in biofouling. Initial studies will require characterizing the peptides to better understand the system.

Student Qualifications: Students have to have completed CHEM 280 (or CHEM 190); completion of at least CHEM 240 would be benefitial but not necessary.

Dates: May 22 – July 14
