Patrones de actividad y densidad del ocelote (Leopardus pardalis) en la reserva de la biosfera "Sierra del Abra Tanchipa", San Luis Potosí, México. Colegio de Postgraduados
Martínez Hernández, Abraham.
México cuenta con escasos estudios sobre el ocelote (Leopardus pardalis) a pesar de ser una especie en peligro de extinción. En el Estado de San Luis Potosí, se ha confirmado la presencia de poblaciones residentes y probablemente se encuentran en situación de riesgo debido a las intensas modificaciones del hábitat. Por esta razón es necesario generar información para conocer el estado actual de la población y para implementar estrategias efectivas de manejo para la conservación de esta especie en la región. El objetivo del estudio fue conocer la abundancia, densidad y los patrones de actividad del ocelote en la Reserva de la Biosfera Sierra del Abra Tanchipa, empleando un método de captura–recaptura con el uso de cámaras–trampa. El estudio se realizó de...

Anteaters on the edge: giant and lesser anteaters (Myrmecophaga tridactyla and Tamandua tetradactyla) at their geographic distributional limits in Paraguay Iheringia, Sér. Zool.
Laino,Rafaela; Musalem,Karim; Caballero-Gini,Andrea; Bueno-Villafañe,Diego; González-Maya,José F.; Chaparro,Silvina.
ABSTRACT Species tend to be less abundant at the limits of their geographic distribution. Giant and lesser anteaters have their southernmost limits in Argentina and Paraguay, where scarce information exists regarding their ecology and conservation. We present a study carried out in the Paraguay River floodplain, in an area dedicated to cattle rearing using native grasses in a subtropical flooded savanna associated with naturally occurring forest islets, wetlands and palm groves. Using camera-traps within three different forest types, we estimated parameters related to habitat preference, social behavior and activity patterns of both species. Results show that capture success was greater in the Floodable sub-humid forest islets (FSF), compared to other...

Differences in the mammalian habitat use in a mosaic of vegetation types of an Atlantic rain-forest reserve, Brazil Mastozool. neotrop.
Ferreguetti,Atilla C; Tomas,Walfrido M; Bergallo,Helena G.
This study aimed to evaluate how habitat use by medium and large sized mammals was related to different vegetation types in an Atlantic rain-forest reserve in south-eastern Brazil. Our hypotheses were that each vegetation type found in the Vale Natural Reserve (VNR) will present a different mammal species composition, and that mammal species richness and relative abundance will be higher in areas nearest to water. We installed 39 camera traps in the VNR, and used two covariates to characterize the different vegetation types (density of trees and lianas). We also used one spatial covariate: the distance to the nearest water resource. We recorded 26 medium- and large-sized mammal species. The mammalian assemblage was structured by veg­etation type and the...
