In cities, habitats classified as green areas are especially important for the conservation of species. Therefore, understanding how different biological groups are influenced by differences in the structures of green areas is relevant when planning urban environments. The aim of this study was to evaluate the influence of different types of green areas to the taxonomic and functional diversities of ants and spiders and to discuss the importance of green area management for both groups. We sampled three categories of green areas: forest fragments (40 sample points), vacant lots (20) and gardens/backyards (20), where we evaluated the taxonomic and functional richness and composition of both groups of organisms. At each sample point, we used several techniques, such as: entomological umbrella, Winkler extractors and manual collection. We sampled 149 ant species and 97 spider species. Our results demonstrate that there are differences in the diversity of ants and spiders, as well as in the number of functional groups of ants between the different types of green areas. As expected, forest fragments are the ones that most contribute to the observed diversity, and our findings highlight the importance of evaluating the biotic influence of green areas at a smaller spatial scale.

Here, we describe the sighting of Philodryas nattereri preying on a Tropidurus. hispidus lizard in Sento-Sé - Bahia, Brazil, located in the central portion of the Caatinga, in a high priority conservation area of the biome. The event was observed in April 2021. This study provides information on the diet of this animal in the Caatinga biome. It thus provides another account of the natural history of snakes, which in itself is a valuable contribution to scientific knowledge since little is known about these animals due to their rarity in nature.
