Resumen

This resource provides updated information on the distribution of Aplochiton taeniatus and A. zebra in Chile and Argentina, based on a bibliographic review and recent local sampling efforts in TDF. The dataset includes GIS vector layers with georeferenced records of Aplochiton occurrence, along with information on each sampling site and its corresponding reference. Basin boundaries are also provided, as well as base maps of Argentina, Chile, and Tierra del Fuego.

Información Técnica

To estimate watershed boundaries, we used the ALOS World 3D – 30 m (AW3D30) digital elevation model from OpenTopography (desftp://ftp.eorc.jaxa.jp//pub/ALOS/ext1/AW3D30/release_v2012_single_format/), which has a spatial resolution of 30 meters. Watershed limits were delineated using the GRASS GIS “r.watershed” tool (Neteler, M., & Mitasova, H. (2008). Open Source GIS: A GRASS GIS Approach. Springer) within the QGIS 3.24 Tisler application (https://qgis.org), using default parameters. Occurrence points of Aplochiton were obtained through a bibliographic review of 34 scientific publications and our own electrofishing surveys conducted in Tierra del Fuego.
