HIMMELSBACH, Wibke et al. Post-fire butterfly diversity in a pine-oak forest in northeast Mexico. Rev. Mex. Biodiv. [online]. 2024, vol.95, e955258.  Epub 07-Out-2024. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2024.95.5258.

Recently, a decrease in insect abundance and diversity has been described, as well as an alteration of the forest fire regime. Due to the sensitivity of butterflies to environmental changes, we studied the richness of butterflies in two forests, one affected by fire and the other without signs of fire. By means of transect sampling and butterfly trapping during the 4 seasons of the year, the floristic and butterfly diversity was determined. The analysis of the data obtained showed that the forest with fire had a greater diversity of flowers and butterflies than the control area. Comparing the 2 forests, a dissimilarity of 27% and 41% was confirmed between the species richness of flowers and butterflies, respectively. In addition, a significant variation in the presence of flowers and butterflies was observed throughout the year in the burned area, which was not significant in the control area. Therefore, it is important to study the effect of forest fires on plant and animal diversity, and to consider their results in forest management plans.
