Figure 1. Distribution of occurrence records of the three
species of Amazonian wild canids in South America. Data obtained through
literature, databases, and field inventories. A - Atelocynus
microtis (short-eared dog); B - Cerdocyon thous (crab-eating
fox); and C - Spheotos venaticus (bush dog).
We searched for geographic information on the rare localities and
municipalities whose coordinates were unavailable using Google Earth
v7.1.2 (https://www.google.com/earth/) and online gazetteers (e.g.,
directory of cities and towns in the world; www.fallingrain.com/world).
Using these same resources, we checked all records with coordinates to
ensure the best reliability of the occurrences used in this study.
Specifically, we evaluated whether each point was minimally consistent
with what is already known about each species’ distribution. Some doubts
were solved by the researchers who collected the data. In addition,
points that did not have precise information on geographic coordinates,
or corresponded to questionable places, such as rivers or lakes, were
discarded. Also, duplicated coordinates recorded in different databases
were discharged. The remaining records (Supplemental Material-Table S1)
were used for niche modeling, producing maps of the potential
distribution for each species, considering the climatic variables, and
analyzing generalized linear models (GLM) based on land use data.
