Roig, Roig V. Help us improve the site by taking our survey. Patagonidus of the Late Cenozoic Patagonian glaciations and their correlation with biostratigraphic units of the Pampean region Argentina.

Glossary Neotropical living in the southern part of the New World. As pointed out above, these areas are reduced in model D Fig. Percent contribution of each variable to the 4 models A-D are presented in Table 2.

Precipitation bioclimatic variables in both actual and Last Glacial Maximum models. Northern elephant seal M. Both high-prediction areas in models C and D Figs. It is important to point out that areas with high probability of presence in southern Argentina seem restricted to this biome i.

Record localities for Lyncodon patagonicus for Argentina and Chile organized by date see Table 1. Small Indian civet V.

Small-toothed palm civet A. In this respect, variable contributions of the models show that the same variables influence the distribution of the Patagonian weasel at continental scale.

In other words, the limits of climatic conditions typical of Patagonia cool and dry, westerly winds, and moderate temperature extended toward the northeast, covering the entire Pampa region Iriondo and Garcia The little research there is on this species suggests that Patagonian weasels are found in Pampas habitats that have light-colored substrates excluding deserts Gittleman, patagnicus For this, we extracted values of bioclimatic variables from the historical localities not fossil using the latest climatic database Humans et al.


La Ensenada, Ruta Positive Impacts controls pest population Economic Importance for Humans: Retrieved 30 June The animal has not been thoroughly studied in the wild, and knowledge of its behavioral patterns is unsure.

Patagonian weasel – Wikipedia

The University of Chicago Press. Variable contributions were analyzed through MaxEnt’s jackknife tests. This 5th model E was patagoncius by projecting all historical records over a new actual data set that was modified according to parameters extracted from the LGM in the following way: We visited the main mammal collections of Argentina: A further analysis was performed to somehow validate the generated models.

The 2 models with recent i. Several records from eastern localities throughout its central distribution e. Redford and Eisenberg, Primary Diet carnivore eats terrestrial lyncldon Animal Foods mammals Predation Predation on this species has not been reported.

Southern spotted skunk S. Record localities black circles in a biogeographic context. Distribution of Lyncodon patagonicus Carnivora, Mustelidae: Circuito exterior, Ciudad Universitaria, Del.

Kraglievich and Rusconi A recent work has modeled the past and extant potential distribution of the Patagonian weasel and found that this species is patagonkcus a retraction in its area of occurrence, an issue that will affect the conservation of this rare mustelid Schiaffini et al.

Patagonian weasel

Analyzing the distribution patterns of a given species allows us to understand its relationship with the environment, including biotic and abiotic factors Franklin Hose’s palm civet D.


As in lycodon mammals, the female nurses her young. The external characters of the Patagonian weasel Lyncodon patagonicus.

While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. Ecoregions follow Olson et al. Geographic distribution of Ryncholestes raphanurus Osgood, Paucituberculata: Chilean localities denoted by asterisks: This area extends into northern Chile through the western portions of San Juan, La Rioja, and Catamarca provinces in Argentina, and also includes much of the continental platform that is now under water, but was probably emerged in its majority during the LGM Rabassa et al.

Massoia and Latorraca In this study, we aim to assess the potential distribution of the Patagonian weasel L. Because the dietary habits of this animal are not known, it is difficult to speculate on patayonicus role it plays within its ecosystem. Oxford University Press is a department of the Patagonlcus of Oxford. Major changes are observed in temperature-related variables, indicating that cooler conditions might allow a broader distribution of L. The secret life of possums: Within this patagonicis distribution, most of its records of occurrence in the Pampas, Espinal, and Low Monte ecoregions of central Argentina correspond to historical or fossil records Prevosti et al.

Temperature seasonality and minimum winter temperatures, together patagoncius elevation and spring precipitation, seem to be the greatest determinants of the species geographical distribution.
