Our objectives were to: (i) collect hourly temperature, relative humidity and barometric pressure data within one cave for one year; (ii) model the data collected to investigate whether there is a temperature signal associated with a past climate regime; (iii) sample for cave-adapted arthropods; and, (iv) make predictions whether these cave-adapted insects are at risk of extinction due to current global climate change.  During this one-year study (winter 2009 through spring 2010), we deployed numerous temperature and relative humidity data loggers in a one cave and at various points along the surface directly above the cave on Grand Canyon Parashant National Monument. This project was funded by the USGS Western Regional Office.
