In order to contribute to the knowledge of this reptile, a study on aspects related to its distribution, density and diet was carried out. The reptile community was composed of nine species, of which <em>L. lorenzmuelleri </em>and <em>L. robertoi </em>occupied the higher altitude environments, the relative densities were low for the high-altitude species and high for those from the lowlands. <em>Liolaemus lorenzmuelleri </em>predominated in low-altitude scrub environments (2.990 to 3.430 masl). Its relative density was low, reaching a maximum of 0.15 individuals in 100 m<sup>2</sup>, it does not generally overlap with other species and it was only recorded in the summer season. The species presented sexual dimorphism in size and weight in favor of the males, its activity was maximum at the hottest hours and the diet presented an important vegetable component. Its restricted distribution and the important mining activity in its distribution area, are in line with its category of threatened species.</p> Gabriel Lobos Copyright (c) 2022 Gabriel Lobos 2022-12-31 2022-12-31 86 2 31 39 10.4067/S0717-65382022000200031 PIT-tag as permanent marking method on Myotis chiloensis (Chiroptera: Vespertilionidae) and Tadarida brasiliensis (Chiroptera: Molossidae) in central Chile <p>Tracking and monitoring of bat populations have frequently involved the use of inappropriate marking methods. Due to their small size, passive integrated transponders (<em>PIT-tag</em>) provide a permanent mark for small vertebrate species through their sub-dermal implantation. However, few studies assess their effects on bats. Here we present the first study on the effect of PIT-tags on bats in Latin America. We evaluated the effect of the use of <em>PIT-tag </em>as a permanent mark on the recapture rate and body condition in <em>Myotis chiloensis </em>and <em>Tadarida brasiliensis </em>in central Chile. For both species, we marked a group of individuals with <em>PIT-tag </em>and left an equivalent group without a mark. In six surveys, between January and March 2019, we captured a total of 262 individuals, 176 corresponding to the species <em>M. chiloensis </em>and 86 to <em>T. brasiliensis</em>, with a total of 43 and 33 recaptures, respectively. The use of <em>PIT-tag </em>had no effect neither on the recapture rate nor body condition for both bat species. Although more investigations are required, our results suggested that the use of <em>PIT-tag </em>as a marking method is adequate and safe for this bat species and it could be implemented in long-term studies.</p> Martín A.

In eight experimental feeders we recorded 1,118 social interaction events, which included 366 aggressive behaviors (32.74 %). This resource caused social instability in some species, suggesting comparative differences in the expression of agonistic behaviors. In addition, the 34.78 % of the granivorous birds described for the study area used the feeders, which indicate that they are not suitable to assessing species richness.</p> Matías Portflitt-Toro Rene Quispe Camila P.

We evaluated the temporal and spectral properties of the stridulation using digital processing software. The results of the variables studied indicate that the sound is in audible ranges for conspecifics and potential predators. We discuss the potential ecological significance of the use of this distress call and how it might relate to its environment.</p> Nicolás González-Véliz Nelson A. Velásquez José M.

There are scarce studies that address the role of the skunk as ectoparasite host; however, the great plasticity of <em>A. tigrinum </em>to inhabit different environments and its strict to moderate specificity for Carnivora order suggest this mephitid as a potentially suitable host for this tick species.</p> Jonatan Manqui Felipe A.
