Recent syntheses indicate that global warming affects diverse biological processes, but also highlight the potential for some species to adapt behaviourally or evolutionarily to rapid climate change. Far less attention has addressed the alternative, that organisms lacking this ability may face extinction, a fate projected to befall one-quarter of global(More)
Understanding the determinants of variation in the extent of species distributions is a fundamental goal of ecology. The diversity of geographical range sizes (GRSs) in mammals spans 12 orders of magnitude. A long-standing macroecological model of this diversity holds that as body size increases, species are increasingly restricted to occupying larger GRS.(More)
Widespread recognition of the importance of biological studies at large spatial and temporal scales, particularly in the face of many of the most pressing issues facing humanity, has fueled the argument that there is a need to reinvigorate such studies in physiological ecology through the establishment of a macrophysiology. Following a period when the(More)
Global warming is now recognized as the dominant threat to biodiversity because even protected populations and habitats are susceptible. Nonetheless, current criteria for evaluating species' relative endangerment remain purely ecological, and the accepted conservation strategies of habitat preservation and population management assume that species can mount(More)
Physiological processes are essential for understanding the distribution and abundance of organisms, and recently, with widespread attention to climate change, physiology has been ushered back to the forefront of ecological thinking. We present a macrophysiological analysis of the energetics of geographic range size using combined data on body size, basal(More)
IN DECEMBER, AS WE CELEBRATED THE 40TH ANNIVERSARY OF THE ENDANGERED SPECIES ACT and all of its accomplishments, the U.S. Fish and Wildlife Service (USFWS) terminated support for the recovery of an icon: the Kemp’s ridley sea turtle (Lepidochelys kempii). This sea turtle nearly slipped into oblivion in the 1980s, and controversial tactics were used to save(More)
The Coastal Plain of the southeastern U. S. is one of the planet's top biodiversity hotspots and yet many taxa have not been adequately studied. The plethodontid salamander, Desmognathus auriculatus, was originally thought to occur from east Texas to Virginia, a range spanning dozens of interfluves and large river systems. Beamer and Lamb (2008) found five(More)
Live-trapping elusive animals is often challenging, hampering the achievement of reasonable sample sizes for molecular studies. In such cases, the use of noninvasive samples (NIS) is critical in many research fields, mostly related to ecology, management and conservation of wild species. We analysed the influence of several variables potentially associated(More)
