The Harmon-Threatt lab at the University of Illinois Urbana-Champaign is seeking a motivated, hardworking undergraduate student to join our team for the spring 2020 semester. The successful candidate will work with Dr. Karl Roeder on a recently funded project examining if multifunctional woody polycultures increase insect biodiversity and food web stability. The position will mostly … Continue reading Job Announcement: Undergraduate research quantifying insect biodiversity and trophic structure of agricultural food webs
Our newest paper of 2019 and the first NEON ants paper is out in Ecology!!! "In an era of rapid climate change, and with it concern over insect declines, we used two theories to predict 20‐year changes in 34 North American ant communities. The ecosystems, from deserts to hardwood forests, were first surveyed in the … Continue reading NEW PAPER OUT! Species Energy and Thermal Performance Theory predict 20‐year changes in ant community abundance and richness
Over the past few years, I have tried to post once every month or at least every other month with updates from my research or outreach. This came to a crashing halt after BioBlitz last year as I finished off the last few sections of my dissertation and prepared to defend. After a successful defense, … Continue reading PhD and future postdoc in Illinois!
Once a year, there is an annual Bioblitz that takes place in different locations, generally parks or natural areas that are protected, around Oklahoma. These have occured for the past 15 years in this state and I think really help bring together a diversity of people who love nature. Priscilla Crawford leads the organization of these … Continue reading Oklahoma BioBlitz 2018
A slight delay in posts as I have been gone or busy writing up portions of my dissertation. In September, our lab finished off the last sampling on the SALT grant for the year at three locations in the midwest United States. Having never visited two of these states before, I was quite excited to … Continue reading Quantifying invertebrate responses to nutrient additions in North American grasslands
Third paper of 2018 is out in Ecological Entomology! Here we look at daily temperature changes, and how such changes regulate activity of red imported fire ants and other native species. This was a pretty fun project that arose from observations during data collection for my first dissertation chapter. Specifically, I was noticing that fire … Continue reading NEW PAPER OUT! The role of temperature in competition and persistence of an invaded ant assemblage
Second paper of 2018 is out in Ecology! This one was led by Rebecca Prather, fellow graduate student in the Kaspari lab, and demonstrates how seasonal and daily temperature differences affect foraging for resources by ants. The abstract is listed below and sums up some of the key results... "As ecosystems warm, ectotherm consumer activity should … Continue reading NEW PAPER OUT! Using metabolic and thermal ecology to predict temperature dependent ecosystem activity: a test with prairie ants
