RESUMEN Documentamos una nueva localidad para el raro ratón selvático Abrawayaomys ruschii, en la provincia de Misiones, Argentina. El individuo, reconocido por sus pelos espinosos distintivos, fue recuperado del excremento de un ocelote, Leopardus pardalis (Mammalia, Felidae). Este registro contribuye a llenar el vacío entre localidades previas. Abrawayaomys ruschii Cunha and Cruz, 1979 is a spiny, forest dwelling sigmodontine, endemic to the Atlantic Forest (Pardiñas et al. 2009). Its presence in Argentina is only known from five localities from a relatively small geographic area in the Province of Misiones. In the red book of Argentine Mammals (Ojeda et al. 2012), Gil et al. (2012) referred this genus as Endangered [EN B1a,b(i,iii)], based mostly on its restricted and fragmentary distribution. At that time, populations from Argentina were included in a separate, supposedly endemic species, A. chebezi Pardiñas, Teta and D’Elía, 2009, which is now considered a synonym of A. ruschii. In this note we present a new locality for A. ruschii in Misiones, and reevaluate the information presented by Gil et al. (2012) to address its conservation status. Reibido el 6 de diciembre de 2018.

These and other prey remains from the same scat are housed at the Instituto de Biología Subtropical under the catalog number IBSI Mam F152. A part of the scat was sent to the American Museum of Natural History to identify the predator via molecular analysis, and the rest was dried at 35 °C and disaggregated with dissecting forceps (see Reynolds & Aebischer 1991). Diagnostic remains (i.e., hair, bones, nails, teeth, feathers, and scales) were identified to species level using keys and reference collections (i.e, Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”). Abrawayaomys ruschii is the only sigmodontine rodent in northeastern Argentina with hairs modified into spines. Spiny hairs are rigid, flat (dorsoventrally compressed), broadest at its midpoint (~0.22 mm), and with a dorsal longitudinal groove.

We used camera traps to document the use of a salt lick by Linnaeus’s two-toed sloth Choloepus didactylus (Linnaeus, 1758) from December 2014 to November 2015 in a lowland Ecuadorian forest. We obtained 201 videos of sloths and analyzed if rain or lunar-phase inf uenced these visits. Visits were positively correlated with monthly rainfall and negatively correlated with lunar illumination, but correlations were not signif cant. We consider three hypotheses for visiting licks: (a) to supplement their diet, (b) to help digestion, and ( ) to obtain water. RESUMEN La geofagia involucra consumo de tierra para complementar la dieta y facilitar procesos digestivos. Utilizamos cámaras para documentar el uso de un saladero por perezosos de dos dedos de Linnaeus Choloepus didactylus (Linnaeus, 1758), desde diciembre 2014 a noviembre 2015, en un bosque de tierras bajas ecuatoriano. Obtuvimos 201 videos y analizamos si la lluvia o la fase lunar inf uyeron en estas visitas. Estas se correlacionaron positivamente con precipitación mensual y negativamente con iluminación lunar, pero las correlaciones no fueron signif cativas. Consideramos tres hipótesis para visitar saladeros: (a) complementar dieta, (b) ayudar a la digestión y (c) obtener agua. Geophagy is the deliberate and regular consumption of soils, clay, and related mineral substances (Abrahams & Parsons 1996; Wilson 2003), as a method for animals to supplement their diets (e.g., mineral supplements) or facilitate digestive processes (e.g., detoxif cation of plant secondary compounds), or both (Kreulen 1985; Gilardi et al. 1999; Krishnamani & Mahaney 2000; Voigt et al. 2008). As such, it is closely related to the health of individuals and populations (Molina et al. 2014). Reasons why a given taxon consumes a given soil at a given time are poorly understood (Brightsmith 2004), and remain speculative (Abrahams 1999). It is commonly agreed that the practice of geophagy may serve a wide variety of purposes for different taxa, and that there is no single explanation for it (Wilson 2003).

El peludo (Chaetophractus villosus) es uno de los armadillos más comunes y abundantes de Argentina (Abba et al. 2014a). Es un animal omnívoro y, en su dieta, incluye gran variedad de ítems, desde escarabajos, hormigas, pequeños vertebrados y carroña (Casanave et al. 2003, Arriagada et al. 2017, Gallo et al. en prensa). En los últimos años se ha detectado una expansión en la distribución de C. villosus, posiblemente facilitada por las actividades humanas (Poljak et al. 2007; Abba et al. 2014b; Gallo et al. 2017). Esta ampliación es muy notoria ya que desde su lugar de origen, situado en la Región Pampeana (Poljak et al. 2010), ha invadido en tiempos históricos toda la Estepa Patagónica (sensu Brown & Pacheco 2006). Desde mediados del siglo XIX naturalistas y viajeros notaron que la mayor parte de la Patagonia estaba habitada sólo por un armadillo, Zaedyus pichiy, y que C. villosus estaba restringido a la zona norte de esta región (Burmeister 1893; Hatcher 1903; Darwin 1833; De la Vaux 2008).

Hace aproximadamente 16 años, Deferrari et al. (2002) confirman la introducción y establecimiento de C. villosus en la Isla Grande de Tierra del Fuego y, posteriormente, Poljak et al. (2007) hacen los primeros trabajos sobre ecología de la especie en este territorio. Luego Poljak et al. (2010), mediante técnicas moleculares, confirman un avance hacia el sur de la especie pero no logran ajustar temporalmente este fenómeno. Seguido a esto, Abba et al. (2014b) confirman que, en los últimos 100 años, el peludo expandió su distribución unos 1300 km desde el norte de la Patagonia hasta el norte de la Isla Grande de Tierra del Fuego. Finalmente, Gallo et al. (2017) registraron el avance del peludo en la Isla Grande de Tierra del Fuego a una tasa de expansión lineal de 9,35 Km/año, invadiendo prácticamente toda la Estepa Magallánica. Si bien los autores no encontraron una asociación exclusiva de la especie con asentamientos humanos, es muy común ver peludos en cascos de estancias o zonas periurbanas (Gallo et al. 2017).

After being notif ed about the presence of squirrels in the area of San José de Tupungato, Mendoza Province, we interviewed local residents and conducted f eld observations to conf rm this information. Three individuals were observed in a rural area at 1240 masl (33° 17’ 48“ S 69° 08’ 54” W) which were photographed. The presence of the species in the Cuyo region represents a serious threat to production with potential impacts on biological diversity. La ardilla de vientre rojo Callosciurus erythraeus Pallas 1779, es una especie originaria del sudeste asiático que habita bosques primarios hasta los 1800 msnm (Moore & Tate, 1965). Ha sido introducida con éxito en Japón, Francia, Bélgica y Holanda (Lurz et al. 2013). En Argentina, fue introducida en el año 1970 y liberada en el año 1973 en una estancia en la localidad de Luján, provincia de Buenos Aires, dando origen a la primera población silvestre del país. Siendo en un comienzo mal determinada, ya que se confundió con la ardilla roja Sciurus vulgaris (Recarey 1990), su correcta determinación como Callosciurus erythraeus fue realizada por Aprile & Chicco (1999). Los ejemplares liberados en Argentina provenían de Bélgica (Aprile & Chicco 1999). Recibido 29 de junio de 2018. Aceptado 18 de octubre de 2018. Editor asociado: M. Merino.
