4th pub for 2022 just came out in Journal of Thermal Biology! This work is the first paper from USDA and contains ideas that I have been wanting for test for years. We measured how ramping rate, starting temperature, genetic line, and sex affected critical thermal limits. We then expanded these ideas to look at knock-downContinue reading “NEW PAPER OUT!

NEW PAPER OUT! Thermal traits predict the winners and losers under climate change: an example from North American ant communities
Our next pub for 2021 was just published in Ecosphere. This paper marks one of many papers from our group from our resampling events across the United States that took place in 2017 and 2018. In collaboration with Jelena Bujan, Kirsten de Beurs, Michael Weiser, and Michael Kaspari, we asked which ant genera are increasingContinue reading “NEW PAPER OUT!

NEW PAPER OUT! Thermal diversity of North American ant communities: Cold tolerance but not heat tolerance tracks ecosystem temperature
Our second NEON ants and 5th pub for 2020 was just published in Global Ecology and Biogeography. Led by Jelena Bujan, this is our first paper linking physiological traits like critical thermal max and min (CTmax and CTmin ) to different environmental abiotic conditions at a large geographical scale. A summary from Jelena in GEB… “InContinue reading “NEW PAPER OUT! Thermal diversity of North American ant communities: Cold tolerance but not heat tolerance tracks ecosystem temperature”
NEW PAPER OUT! Seasonal plasticity of thermal tolerance in ants
Great to see another publication out from one of my favorite places to do field work, the University of Oklahoma Biological Station. This is the 4th pub for 2020, which is shaping up to be quite the productive year! Recently published in Ecology, Jelena and I were interested in seeing if thermal tolerance, an importantContinue reading “NEW PAPER OUT! Seasonal plasticity of thermal tolerance in ants”
NEW PAPER OUT! Using metabolic and thermal ecology to predict temperature dependent ecosystem activity: a test with prairie ants
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 shouldContinue reading “NEW PAPER OUT!

Summer heat and mid field season update!
This summer has been quite the adventure. I have been trying out a few different techniques, reading a ton of literature, and trying not to go crazy with all of the ideas. As of this week my first dissertation chapter was submitted and I just got the acceptance letter for our Wichita Mountains Wildlife Refuge AntContinue reading “Summer heat and mid field season update!”
Ant Ecology in New Mexico
New Mexico is a beautiful state. Despite its proximity to both Texas and Oklahoma, I really haven’t spent much time here. At the end of May, I was fortunate to join a team from the Kaspari lab who are resurveying ant transects that were initially measured 20 years ago. They are doing a lot of really cool,Continue reading “Ant Ecology in New Mexico”
Ant Ecology at the University of Oklahoma Biological Station (UOBS)
Labor day weekend brought about an interesting opportunity. Jelena Bujan, ant lover and fellow lab mate in Mike Kaspari’s lab, brought forth an idea about measuring the thermal performance of ants in Oklahoma. We jotted down a rough sketch for the project and then headed to the University of Oklahoma Biological Station (UOBS). Having been stationed there all summer, IContinue reading “Ant Ecology at the University of Oklahoma Biological Station (UOBS)”
Summer Research 2015 – University of Oklahoma Biological Station and Wichita Mountains Wildlife Refuge
Check out my research on ants, size, and stable isotopes (CLICK ME)! Besides working on understanding how size affects an ant’s stable isotope signature, I have also been collecting, identifying, and creating species lists of ants at the University of Oklahoma Biological Station and the Wichita Mountains Wildlife Refuge. So far we have found new recordsContinue reading “Summer Research 2015 – University of Oklahoma Biological Station and Wichita Mountains Wildlife Refuge”
