The greening of the Sahara: past changes and future implications. in Africa from MIS 6-2: Population Dynamics and Paleoenvironments (eds Jones, S. Timing and causes of North African wet phases during the last glacial period and implications for modern human migration. Unraveling the fossil record of foxes: an updated review on the Plio-Pleistocene Vulpes spp. Inferring the joint demographic history of multiple populations from multidimensional SNP frequency data. GADMA: genetic algorithm for inferring demographic history of multiple populations from allele frequency spectrum data. Next-generation phylogeography resolves post-glacial colonization patterns in a widespread carnivore, the red fox ( Vulpes vulpes), in Europe. Range-wide multilocus phylogeography of the red fox reveals ancient continental divergence, minimal genomic exchange and distinct demographic histories. Genome sequence, comparative analysis and haplotype structure of the domestic dog. Genomic and fitness consequences of inbreeding in an endangered carnivore. ANGSD: analysis of next generation sequencing data. ![]() Adaptive changes in hemoglobin function in high-altitude Tibetan canids were derived via gene conversion and introgression. Genomic analysis reveals hypoxia adaptation in the Tibetan mastiff by introgression of the gray wolf from the Tibetan plateau. Genetic convergence in the adaptation of dogs and humans to the high-altitude environment of the Tibetan plateau. Population variation revealed high-altitude adaptation of Tibetan mastiffs. EPAS1 variants in high altitude Tibetan wolves were selectively introgressed into highland dogs. Ancient hybridization with an unknown population facilitated high-altitude adaptation of canids. Arctic-adapted dogs emerged at the Pleistocene–Holocene transition. Differentiation of North African foxes and population genetic dynamics in the desert-insights into the evolutionary history of two sister taxa, Vulpes rueppellii and Vulpes vulpes. Convergent evolution of increased urine-concentrating ability in desert mammals. Thermoregulation and metabolism in a small desert carnivore: the fennec fox ( Fennecus zerda) (Mammalia). Water balance and kidney structure in the fennec. Basal metabolic rate of Canidae from hot deserts to cold arctic climates. A phylogenetic analysis of basal metabolism, total evaporative water loss, and life-history among foxes from desert and mesic regions. Energy expenditure and water flux of Rüppell’s foxes in Saudi Arabia. Biogeography and conservation of taxa from remote regions: an application of ecological-niche based models and GIS to North-African canids. Canids: Foxes, Wolves, Jackals and Dogs (IUCN, 2004). Expansion of the Sahara desert and shrinking of frozen land of the Arctic. Exposure to climate change drives stability or collapse of desert mammal and bird communities. Climate Change in Deserts: Past, Present and Future (Cambridge Univ. Our study provides insights into the mechanisms and genetic underpinnings of a natural experiment of repeated adaptation to extreme conditions. zerda), we identified repeated signatures of selection in genes affecting renal water homeostasis supported by gene expression and physiological differences. ![]() In the extreme desert specialists, Rueppell’s fox ( V. ![]() ![]() Scans for signatures of selection implicated genes affecting temperature perception, non-renal water loss and heat production in the recent adaptation of North African red foxes ( Vulpes vulpes), after divergence from Eurasian populations approximately 78 thousand years ago. We show that adaptation of new colonizing species to a hot arid environment has probably been facilitated by introgression and trans-species polymorphisms shared with older desert resident species, including a putatively adaptive 25 Mb genomic region. Here we generated 82 individual whole genomes of four fox species (genus Vulpes) inhabiting the Sahara Desert at different evolutionary times. Elucidating the evolutionary process of animal adaptation to deserts is key to understanding adaptive responses to climate change. ![]()
