“…Leptuca uruguayensis occurs from Rio de Janeiro on the southeast coast of Brazil (22°51'S, 42°02'W) to Buenos Aires in Argentina (37°45'S, 57°28'W) (Spivak et al, 1991;Thurman et al, 2013;Truchet et al, 2019). The southern distribution range of L. cumulanta now overlaps the northern boundary of L. uruguayensis in Rio de Janeiro and São Paulo state.…”

Climate change is drastically altering environmental conditions and resource availability. Many organisms are shifting their distribution boundaries. Fiddler crabs, for instance, are important ecosystem engineers in coastal environments that have been extending their distribution range poleward. In this study, we evaluated the influence of a range-extending species, Leptuca cumulanta, which has recently overlapped the distribution of the resident species Leptuca uruguayensis. Through a set of field and laboratory experiments, we characterised the degree of territorial overlap between L. cumulanta and L. uruguayensis from the lower to upper intertidal zone in a mangrove area. We also analysed whether the presence of L. cumulanta prevents habitat choosiness or influences agonistic behaviours in L. uruguayensis in territorial fights. We found that both species overlap territories at the same level in the intertidal zone. However, we observed that both habitat choice and agonistic behaviours of L. uruguayensis were unresponsive to the presence of L. cumulanta. The low interference between recent heterospecific neighbours sharing the same space supports coexistence of fiddler crabs L. uruguayensis and L. cumulanta in the early stage of overlapping.
