Abstract
Marsh rats of the species Holochilus vulpinus inhabit mesic and humid environments. For this reason, it is frequently used in paleoenviromental studies to infer past humid conditions. Holocene archeological record indicates that H. vulpinus had a wider geographical distribution than today. Its regional extinction in north Patagonia at the XIX century was attributed to the dry and cold Little Ice Age (LIA). Here we present the finding of a specimen of H. vulpinus from northeastern Patagonia (Valcheta stream, Río Negro province, Argentina), just at the end of LIA. Implications of this novel historical record are discussed.
Acknowledgments
We thank D. Flores and P. Teta (MACN), and Sergio Bogan (Fundación de Historia Natural “Félix de Azara”) for the access to the collections under their care. N. Chimento and E. Guerrero shared fruitful data regarding the distribution of vertebrates and plants in the Late Holocene of Patagonia. U.F.J. Pardiñas shared valuable discussion and literature about Holochilus and Patagonian history. We especially thank the reviewers for their enlightening comments on an early version of the manuscript.
