Is it a lack of search effort or an unsuitable habitat that explains the gaps in the distribution atlas of the Egyptian mongoose?

摘要

This study evaluates whether the absence of Egyptian mongoose records in some areas of the Huelva and Seville provinces is due to a lack of survey effort or unsuitable habitat. A total of 47 UTM 10 × 10 km grid cells without previous records were surveyed between May and July 2020, primarily through track identification under bridges. Presence was confirmed in 46 of the 47 grid cells, supporting the hypothesis that previous absences were mainly due to insufficient sampling. Only one cell yielded no records after three visits. Additionally, one roadkill and one camera-trap detection were also recorded in the study area. Most positive signs were found on riverbanks beneath bridges or drainage under roads (44 out of 49), and the surrounding habitat was predominantly agricultural, with little or no natural vegetation. These findings confirm that the Egyptian mongoose inhabits far more human-altered landscapes than previously assumed, indicating notable ecological plasticity. The high detection success under bridges supports their use as strategic sampling points for monitoring programs. This work highlights the need to update species distribution maps and to re-evaluate existing habitat suitability models.
