| Sumario: | Introduction. Sandflies are vectors of leishmaniasis. Ecological niche
models are currently used to infer the distribution of species in a given
geographic area. So far, there is no evidence on the inference of ecological
niche fragmentation in sandflies.
Objective. Our objective is to implement landscape indices for the
interpretation of the fragmentation of the ecological niche in three species of
sandflies in Central and South America.
Material and methods. Ecological niche models were built for three
species of sandflies in Central and South America in three time periods:
past (Pleistocene), present and future (RCP 8.5). Finally, we used FragStat
analysis to calculate two indices: COHESION and CPLAND.
Results. Our results show a COHESION index higher than 99.8%; while
the values of CPLAND were increasing from 3.4-72.1% depending on the
species and the period.
Conclusion. Ecological connectivity between the patches of the projected
geographic distribution of the ecological niche model was verified among the
three species of sandflies in Central and South America. |
