| Brazil has a high diversity of flies of the genusDrosophila, and part of this richness is represented by thecardini group. We analyzed the fluctuations in the richness and abundance of this group, in environments that had never previously been studied in the northeastern region of Brazil. Among the 28,204 drosophilids sampled, 1,294 belonged to the cardini group and were represented by D. polymorpha, D. cardini, D. neocardini and D. cardinoides. Occurrences ofD. neocardini and D. cardinoides were registered for the first time in the Caatinga. In this biome,D. cardini stood out as having the highest abundance, andD. polymorpha was not observed. In the coastal Atlantic Forest, D. cardini was not registered, but D. polymorpha was found in all the localities... |
