Summer 2014 MAP Research Jackie Brown
Interest: Connecting evolution with ecology.Methods: Studies of morphology, behavior,
ecology, molecular population genetics, and phylogeny–Damselflies
• N. American Jewelwings (Calopteryx spp.)• Endemic Hawaiian radiation (Megalagrion spp.)
– Ants• Allegheny Mound Ant (Formica exsectoides)

Is damselfly color throughout this radiation correlated with habitat type?

Team DamselflyProject 1 – Larval ecology of Megalagrion species• Collaboration with Idelle Cooper ‘01 (James Madison
University• Training in damselfly ecology and behavior at Mt. Lake
Biological Station, VA• 3-4 weeks of field work at Waikamoi TNC preserve,
adjacent to Haleakala NP, Maui.• Major questions: What is the larval niche overlap
between two species (M. calliphya and M. hawaiiense)found sympatrically? Do adults defend territories and oviposit according to larval abundances?

Team DamselflyProject 2 – Population structure of N. A. Calopteryx species
• Collaboration with Idelle Cooper ‘01 (James Madison University
• Training in damselfly ecology and behavior at Mt. Lake Biological Station, VA
• Field collections and screening of populations using microsatellites (developed by European Calopteryx researchers and tested by Spring 2013 Bio 373 students)
• Major questions: Do two species have different population structures (caused by different larval niche breadth)?
• Will set basis for future studies of species hybridization

Team Ant (3 students)• Formica exsectoides (Allegheny mound
ant)• Demonstrates supercoloniality – extreme
form of cooperation among non-relatives• Unicoloniality (populations a single
supercolony) is usually associated with ecologically successful invasive species (e.g. the Argentine ant)
• Builds on projects of many students in Bio 150/240 and MAPs
• Clare Gunshenan ’14 Fall 2013 MAP demonstrated lack of supercolony border at distances of greater than 100k.
Summer goals:• Increase geographic sampling to eastern
part of range (Appalachian Mtns.) • Correlation of genetic structure,
behavior, and chemical signatures (co-advised by Leslie Lyons)
