Desert resource environments(***,food)are tied to limited,highly localized rainfall regimes which generate microgeographic variation in the life histories of ***,enhanced growth rates,reproduction and survivorship are observed in response to increased resource availability in a variety of desert plants and short-lived *** examined the thermal ecology and reproduction of US federally threatened mojave desert tortoises(Gopherus agassizii),long-lived and large-bodied ectotherms,at opposite ends of a 250-m elevation-related rainfall cline within Ivanpah Valley in the eastern mojave Desert,California,*** operative environments in both the upper-elevation,“Cima,”and the lower-elevation,“Pumphouse,”plots corresponded with daily and seasonal patterns of incident solar *** received 22%more rainfall and contained greater perennial vegetative cover,which conferred 5°C-cooler daytime shaded *** a monitored average rainfall year,Cima tortoises had longer potential activity periods by up to several hours and greater ephemeral *** resource availability in Cima was associated with larger-bodied females producing larger eggs,while still producing the same number of eggs as Pumphouse ***,reproductive success was lower in Cima because 90%of eggs were depredated versus 11%in Pumphouse,indicating that predatory interactions produced counter-gradient variation in reproductive success across the rainfall ***-use impacts on deserts(*** energy generation)are increasing rapidly,and conservation strategies designed to protect and recover threatened desert inhabitants,such as desert tortoises,should incorporate these strong ecosystem-level responses to regional resource variation in assessments of habitat for prospective development and mitigation efforts.
