Abstract: We investigated the influence of Quaternary climate fluctuations on the current distribution of three species of Leguminosae (Fabaceae) occurring in the Chaco. Potential distribution models of Bauhinia hagenbeckii, Muellera nudiflora and Neltuma rubriflora with a supposed endemism area were generated. The Last Interglacial, Last Glacial Maximum, Holocene Middle and current scenarios were used. The species showed a potential distribution according to the South American biogeographic history regarding the glacie… Show more

“…During this period, the River channels were wider and seasonally dry during glacial intervals (Clapperton, 1993), potentially serving as refugia for flora, including B. yatay , that was adapted to humid climates (Ab'Sáber, 1977). The LGM paleodistribution of suitable habitat of Chaco tree species, which are currently distributed along the Paraná River, also has indicated a slight northward expansion (Giudicelli et al., 2019; Sinani et al., 2022; Spichiger et al., 2004). Therefore, we can infer that this area would have provided favorable conditions for the Chaco flora during the climatic fluctuations of the LGM.…”
