Abstract As an important human-caused disturbance factor, urbanization has significantly changed the structure of natural habitats and influenced the composition of animal communities. The characterisitions of abundant population amount, high spcies diversity, and easy to be collected of ants make these species become excellent models for studying the effects of land-use types on the composition of animal communities in urban areas. In May 2018, ants were sampled from 3 land-use types (‘garden and greenland’, ‘dry farm’ and ‘woodland’) using pitfall traps in an urban area of Nanchong city, Sichuan province. A total of 1 847 ant individuals were collected. The proportion of Tetramorium tsushimae was the highest in ‘garden and greenland’ (73.80%), and significantly higher than that of Monomorium chinense in ‘dry farm’ (25.48%) and Pheidole nodus in ‘woodland’ (28.79%). There was no significant difference in the number of indiviuduals and species richness among the 3 habitats, but the Simpson diversity index and Pielou evenness index of ant community in the habitat of‘garden and greenland’were significantly lower than those in the habitats of‘dry farm’and‘woodland’; the composition of ant community in‘woodland’was moderately different from that in‘garden and greenland’( q = 0.444)and‘dry farm’( q = 0.500), and the community composition in‘garden and greenland’and‘dry farm’( q = 0.647)was moderately similar. Therefore, the compositions of ant communities are varied in different land-use types in urban areas, and the habitat of ‘garden and greenland’ is more likely to facilitate the formation of dominant species than ‘dry farm’ and ‘woodland’.

Abstract A publicly accessible database of ants associated with dry forest fragments and urban environments in Santa Marta, Colombia, is presented through the Colombian Biodiversity Information System (SIB). Capture methods included the installation of pitfall traps, protein and carbohydrate baits, extraction by the Winkler method of ants associated with leaf litter and manual collection of ants foraging on tree vegetation. The dataset contains 54 323 records, distributed in seven subfamilies, 42 genera, 88 species and nine morphospecies. This list is a tool to encourage the study and conservation of ants in urban areas.
