Once thought to exclusively inhabit its namesake(名义,同名物) mountain range, the threatened Andean cat—a house cat-sized feline1(猫科动物) that resembles a small snow leopard2 in both appearance and habitat—also frequents the Patagonian steppe(大草原) at much lower elevations3, according to a new study published by the Wildlife Conservation Society and partners. The finding represents a range extension for the Andean cat, which normally occurs at altitudes above 3,000 meters (approximately 9,800 feet). The new survey presents evidence of the cats occurring at elevations as low as 650 meters (approximately 2,100 feet) on the Patagonian steppe. The species is listed as "Endangered" on the World Conservation Union's Red List and may number only 2,500 individuals throughout its entire range.

The study appears in the recent edition of CATNews. The authors include: Andres Novaro and Lorena Rivas of the Wildlife Conservation Society and CONICET, Argentina; Susan Walker of the Wildlife Conservation Society; Rocio Palacios of Alianza Gato Andino; Sebastian di Martino of Department of Protected Areas of the Province of Neuquén; Martin Monteverde of Centro de Ecología Aplicada del Neuquén; Sebastian Canadell of Universidad Nacional de Cordoba; and Daniel Cossios of Université de Montréal.

"These confirmed records show the lowest elevations ever reported for the Andean cat," said WCS conservationist Andres Novaro, lead author of the study. "According to genetic4 studies underway led by Daniel Cossios, this new population appears to represent an evolutionary5 lineage(血统,家系) distinct from the highland6 population."

Prompted by a lone7 photograph of two Andean cats in the foothills of central Argentina, the research team surveyed approximately 31,000 square kilometers (approximately 12,000 square miles) of Argentina's Mendoza and Neuquén provinces in 2007-2009. The team collected samples from several locations that included scat, skulls8, and skin, all of which were confirmed with DNA9 analysis. In addition, the researchers conducted surveys with inhabitants of the region. The conservationists also found evidence of three other small cat species: Geoffroy's cat, pampas(草原) cat, and jaguarundi(獭猫) .

The Andean cat's range extension coincides with the known distribution of the mountain vizcacha, a rabbit-like rodent10 that inhabits both the Andes Mountains and Patagonian steppe and is the Andean cat's primary prey11.

"Discovering a new population of Andean cats is an important finding for this elusive12 and rare species," said Mariana Varese, Acting13 Director of WCS's Latin America and Caribbean Program. "Determining the range of the Andean cat in the Patagonian steppe will provide conservationists with a foundation for later conservation plans."

Threats to the newly discovered population of Andean cat include goat herders(牧人) who assume the felines14 are preying15 on their livestock16, oil exploration activities that destroy habitat, and new roads that open up formerly17 inaccessible18 areas to poachers.
