ÿþThe puma is an iconic predator that ranges throughout the puma zapatos Americas, occupying diverse habitats. Previous phylogeographic analyses have revealed that it exhibits moderate levels of genetic structure across its range, with few of the classically recognized subspecies being supported as distinct demographic units. Moreover, most of the species' molecular diversity was found to be in South America.
Our analyses indicate that this expansion occurred in South America, prior to the hypothesized re-colonization of North America, which was therefore inferred to be even more recent. The puma by alexander mcqueen estimated demographic history supports the interpretation that pumas suffered a severe demographic decline in the Late Pleistocene throughout their distribution, followed by population expansion and re-colonization of the range, alexander mcqueen for puma initiating from South America.
The puma ( Puma concolor Linnaeus, 1771) is a large felid that ranges throughout the Americas, exhibiting the broadest latitudinal distribution of any terrestrial mammal ( Nowak, 1999 ). Pumas have remarkable dispersal capabilities ( Maehr et al. , 2002 ; Beier et al. , 2003 ) and successfully occupy a diverse array of puma black shoes womens habitats, illustrating their potential to adapt to the breadth of environmental conditions occurring across the continent, from tropical forests and marshes to dry scrubland and cold Andean or Patagonian biomes ( Redford and Eisenberg, 1992 ; Nowak, 1999 ). Pumas are solitary and territorial, with large home ranges. Females tend to occupy smaller areas and disperse shorter distances, thus being more philopatric than males ( Logan and Sweanor, 2001 ; Maehr et puma by rihanna slides al. , 2002 ).
Fossil evidence indicates that pumas were already present in North America 0.4 million years ago (MYA) ( Kurtén and Anderson, 1980 ). In parallel, molecular data ( Johnson et al. , 2006 ) have led to an estimate of its divergence from the sister-species P. yagouaroundi of 4.17 MYA (C.I.: 3.16 6.01MYA), suggesting a much longer history as a distinct evolutionary lineage.
We obtained blood and tissue samples from 77 pumas including wild individuals captured during field-ecology projects, caught by farmers or road-killed, as well as captive animals with known geographic origin ( Table S1 ).
