Northern records of Mazama temama and Leopardus wiedii in northeastern, Mexico

Abstract

Historical records of the red brocket deer (Mazama temama) and the margay (Leopardus wiedii) in northeastern Mexico, particularly were limited to the southern of Tamaulipas. However, between September 2020 and November 2021, a mammal monitoring project was carried out using camera traps in the southern portion of Altas Cumbres, Victoria, Tamaulipas. Five camera traps georeferenced were installed and established near wildlife crossing sites. Among the documented mammals, the presence of M. temama and L. wiedii stands out, both recorded for the first time in the area. The presence of a pair of red brocket deer increases the northern range of the species to about 61.69 km. While, for margay, the northern record is expanded to 61.80 km, and the most northwestern population located in Nuevo Leon to 47.09 km, being a key link between these populations.
