Noteworthy records and distribution of the Southern Spotted Skunk (Spilogale angustifrons Howell, 1902) in the State of Guerrero, Mexico

Abstract

Spilogale angustifrons is the third smallest carnivore in Mexico. Nationally, the species is not classified under any risk category, while internationally it is considered Least Concern; however, little is known about its local distribution in the country. This study aimed to document new localities and predict the potential distribution of S. angustifrons in Guerrero, Mexico. Presence records were obtained through camera trapping in the state, a review of national scientific literature, searches in national and international scientific collection databases, and citizen science sources. Using these records and a set of environmental variables, a species distribution model (SDM) for S. angustifrons in Guerrero was generated using the MaxEnt algorithm, and the most influential variables were identified. Camera trapping yielded 17 independent records across two localities. Additionally, 13 records were compiled for Guerrero from scientific literature (n = 1), museum collections (n = 6), and citizen science (n = 6). The predicted potential distribution covered 19,390 km², with the Balsas Depression biogeographic province containing the largest suitable area (63.78%). Variable analysis indicated that the species prefers warm regions (>10°C) with moderate mean precipitation (<1,500 mm). The model outputs will help identify priority conservation areas and potential anthropogenic threats to its distribution. Furthermore, new localities in Guerrero were documented, improving our understanding of the species' distribution patterns in the state.
