About the Hadly Lab

The members of the Hadly lab are involved in a wide variety of reserach, but they all share a common interest: What determines and maintains diversity through space and time?  The temporal variation includes events from hundreds to millions of years.  Elevational, latitudinal, thermal and other environmental gradients are of particular interest, scaling from local to global.  Out lab spans vertebrates from amphibians to mammals and includes work in India, Patagonia, SE Asia, and North America.  We use phylochronology (population genetics through space and time), phylogeography, population genetics, morphology, field monitoring of life history traits, behavior, isotopes, GIS and remote sensing data.  We are particularly keen to ascertain ecological and evolutionary responses fo vertebrates to environments of the Holocene (the past 10,000 years.)

Current Research Projects
