In this lab, we believe that science is real, love is love, Black Lives Matter, feminism is for everyone, trans rights are human rights, ants and flies are cool, and everyone is welcome here.
Simple macro lenses can help mobile phone cameras capture insects in stunning detail.
Cities power evolutionary divergence by accelerating metabolic rate and locomotor performance.
With funding from the NSF EPSCOR program and in collaboration with colleagues across the country, we’re embarking on a 4-year mission to investigate epigenetic mechanisms of thermal adaptation in Drosophila
Exploring the natural history and biomechanics of a fast moving australian ant
We used x-ray imaging and 3D visibility graph analysis to study the internal structure of acorn ant nests.
Plotting metabolic rate scaling data in an interactive way. Insect metabolic allometry data In a paper published in 2007, Steven Chown and colleagues compiled a large database of insect metabolic rates. The data demonstrated that insect metabolic rates scale hypometrically with their mass (larger insects have higher metabolic rates than smaller insects, but not proportionally as high; on a mass-specific or gram for gram larger insects are using a lot less energy than their smaller counterparts, both within and across species).
Notes on setting up to do thermolimit respirometry. New aluminum chambers We had these respirometry chambers made by the ASU machine shop, based on the similar ones designed by Sable to use with their peltier-effect heating/cooling plate. The chambers are made from aluminum, have barbed fittings to attach tubing, there is a path through the top so that the incurrent air can thermally equilibrate, a cylindrical cavity to hold the insect, and two threaded caps which tighten onto an O-ring and which have glass windows to allow insertion of a pair of infrared emitter and detector.
