More About Me

I am an ecologist who focuses primarily on species interactions involving insects, spiders, and/or plants using both field-based approaches and molecular methods. Learn more about me below:

My research

Dulotic ants

Since at SUNY Geneseo, my main research efforts have focused on the ecology and population genetics of dulotic ants, Formica subintegra and Formica pergandei (also known as slavemaking ants). These ants are social parasites - they raid the colonies of other ant species (one in particular in the Arboretum, Formica glacialis), kidnap their brood (immature ants, generally as pupae), and when those brood mature in the raiding species' nest, they end up working for their captors. The captured ants do all the foraging for the dulotic ants' colony, take care of their offspring, perform nest maintenance...all the activities they would normally do in their own colonies, but they happen to benefit a different species instead of their own relatives.

Ant-mimicking spiders

Another project I recently started involves an ant-mimicking spider (which I would often see when I was observing my ant colonies). This spider, Myrmarachne formicaria, is in the jumping spider family, but resembles ants in both its morphology and behavior. To pull off the charade, it raises its first set of legs like a pair of antennae, so it appears to be a 6-legged insect instead of an 8-legged spider. This species is native to Eurasia and was introduced to North America relatively recently; so far it is found in Ontario, western New York, eastern Ohio, and northwest Pennsylvania.

Mentoring student researchers

I mentor student researchers studying a variety of subjects relating to the ecology of insects, spiders, and plants, and their interactions, using both field methods and molecular techniques. Here are some examples of student research projects I have supervised recently: 

  • Alli Menendez: Evaluating the use of artificial nests by native bees (2020 - 2021)

  • Julia Ophals and Niaomi VanAlstine: Success of Batesian mimicry in the ant-mimicking spider Myrmarachne formicaria (2020-2021)

  • Bea Dipzinski and Alanna Richman: Effectiveness of Batesian mimicry in the ant-mimicking spider Myrmarachne formicaria (2019-2020)

  • Cassidy Mills (2020 - present): Genetic diversity of a non-native ant-mimicking spider, Myrmarachne formicaria, in its invaded range

  • Daniel Fleischman: Genetic diversity of a non-native ant-mimicking spider, Myrmarachne formicaria, in the Great Lakes (2019-2020)

  • Sam Heraghty: Patterns in native bee diversity: effects of floral resources and habitat (2017-2018).
  • Ally Jones:  Interactions between beech blight aphids, sooty mold fungus, and forest invertebrates (2017-2018)
  • Emily Martin: Extended leaf phenology of the invasive Amur honeysuckle (2017-2018)

Courses I teach

Here are recent syllabi from courses I typically teach:

Roemer Arboretum

Since 2013, I have managed the Spencer J. Roemer Arboretum, which I encourage you to visit frequently!  It is a lovely place to take a walk, relax, and to witness cool natural history. Check out our website and Facebook page.  See some of the organisms reported there on our iNaturalist page.

Past research adventures

I have been fortunate to have been able to pursue research in a variety of study systems and habitats--this photo collage provides an overview:
