With its large variety of wildlife, in addition to the unique climate and terrain, the region is one of immense natural beauty and vast wilderness. Managing the Trans Pecos to provide the variety of natural habitats on which each of these species depends is quite challenging. For example, Galveston gets about 42 inches of rain a year. Day One will be at the El Paso Zoo on Saturday, September 25, 2021 and Day Two will be at Franklin Mountains State Park, Tom Mays Unit on the west side of El Paso off of Loop 375. Comparisons of mark-recapture data on life histories and population dy- namics of the 1 1 commonest species of nocturnal desert rodents inhabiting our experimental study site in the Chihuahuan Desert of extreme southeastern Arizona permitted assessment of the role of evolutionary relationships and ecological factors in the coexistence of these species. Studies investigating the origins of population structure of Chihuahuan Desert taxa have produced dates that range broadly from the late Neogene to the Quaternary (e.g., Sosa et al., 2009, Bryson et al., 2012, Castellanos-Morales et al., 2016, Loera et al., 2017), suggesting that species are likely responding to unique features of this biome.
