Description
Summary:Nannophryne variegata is an endemic species of the southern forests of Chile and Argentina. It has a wide distribution in Chilean territory and to a lesser extent, in Argentine territory. Along this extensive latitudinal distribution, it inhabits different ecological regions, characterized mainly by low temperatures and high precipitation. There are few antecedents regarding habitat preferences and threats to this species. This paper reports on new distribution records in the extreme south of Chile and Argentina. It also describes the characteristics of the habitats it occupies and the representation in protected areas of both countries. Nannophryne variegata is distributed from 37º28’ to 52°10’ South latitude, becoming one the southernmost amphibians in the world. It inhabits different environments that include humid forest associations, peat bogs, Magellanic tundra and neighboring high Andean environments. It is well represented in protected areas with a large number of observed populations. Nannophryne variegata es una especie endémica de los bosques australes de Chile y Argentina. Posee una amplia distribución en territorio chileno y en menor medida, en territorio argentino. A lo largo de esta extensa franja latitudinal de distribución, habita diferentes regiones ecológicas, caracterizadas principalmente por temperaturas bajas y alta precipitación. Escasos son los antecedentes respecto a las preferencias de hábitat y amenazas para esta especie. Este trabajo informa sobre nuevos registros de distribución en el extremo sur de Chile y Argentina. Describe, además, las características de los hábitats que ocupa y la representación en áreas protegidas de ambos países. Nannophryne variegata se distribuye desde los 37º28’ hasta los 52°10’ latitud sur, siendo uno de los anfibios más australes del mundo. Habita diferentes ambientes que comprenden asociaciones boscosas húmedas, turberas, tundra magallánica y ambientes altoandinos vecinos. Se encuentra bien representada en áreas protegidas con un gran número de ...
