Approach to home range of Liolaemus lemniscatus Gravenhorst, 1838 (Squamata, Liolaemidae) in a priority site of mediterranean Chile

2021-08-28T22:55:15-04:00

We characterized the home range (HR) of a population of Liolaemus lemniscatus in a sector of the Cordón de Cantillana Priority Site. The estimated HR average size for six individuals was 55.919 m². Our results show that males have a larger HR size compared to females and they are significantly associated with the patchy distribution of shrub vegetation present in the study area.

First record of Chelonibia testudinaria (Linnaeus, 1758)) (Cirripedia: Chelonibiidae) in northern Chile

2021-11-09T05:10:14-03:00

The first record of the epibiont cirripedium of sea turtles, Chelonibia testudinaria (Linnaeus, 1758), is described for northern Chile (the second record for the species in the country), extending the distribution of this species by almost 10 latitudinal degrees (about 1020 km), and filling a gap in its geographic range in the southeastern Pacific.

Overcoming barriers: Novel records of swimming behavior in Leopardus guigna

2022-02-23T10:41:53-03:00

The distribution range of the güiña cat (Leopardus guigna) is highly restricted and the species is threatened. Owing to the shyness of the animal, uncertainties remain about its behavioral repertoire. In this note, we report two records of swimming for this felid, a behavioral trait that has not yet been described in the literature. These records were obtained in the context of a citizen science project and thus confirm that public participation can help to expand our knowledge of the natural history of elusive species.

Phylogenetic relationships of three endemic and endangered lizard species of Pristidactylus from central Chile based on the cytochrome b

2022-03-25T15:23:43-03:00

Lizards of the genus Pristidactylus distribute in southern South America (Chile and Argentina). In Chile, there are four endemic species (P. alvaroi, P. torquatus, P. valeriae and P. volcanensis) that distribute in the central-south zone of the country. We performed a Bayesian analysis with the mitochondrial gene cytochrome b to assess the phylogenetic position of these four species, which shows that they comprise a high supported clade that is separated from the other species of the genus.

Range extension of Catedral spiny-chest frog, Alsodes gargola Gallardo, 1970: a record in an unknown road of the Chilean Patagonia

2022-03-25T15:17:07-03:00

This article reports the presence of Alsodes gargola Gallardo, 1970 in Paso Las Golondrinas, south of Lago Verde village, Aysén Region, Chile. To validate our finding, we made a phylogenetic analysis with the mitochondrial gene cytochrome b. This record extends the distribution range of this species, which inhabits Chile and Argentina, 130 km to the south. The finding emphasizes the importance of conducting samplings in little-known zones of Chilean Patagonia, especially in those that totally lack antecedents on their herpetofauna.
