RESUMO:

Accounting for evolutionary relationships inter- and intraspecifc is importante for biodiversity conservation. However, the phylogeographic aspect is still little address in the field of systematic conservation planning for the establishment of priority conservation areas. Comparative phylogeography can identify species that have a common history of vicariance. The Lutrinae subfamily has four native Neotropic species: Lontra longicaudis, Lontra Felina, Lontra provocax and Pteronura brasiliensis. All species play the important role of top predator and, due to their sensitivity to environmental degradation, are good indicators of environmental health. Here in this paper, we then analyze the lineages for each of these species and their phylogeographies to determine priority conservation areas following systematic conservation planning. Here we show that Neotropic Lutrinae species separate into 3,3,2 and 4 lineages for Lontra longicaudis, Lontra Felina, Lontra provocax and Pteronura brasiliensis, respectively. There is a concentration of diversification in the central Amazon region and northern Chile. However, conservation should also be given priority to areas with greater endemism, including Mexico and the South Chilean islands. Our work is the first study that directs the prioritization of the Neotropic Lutrinae species complex and still on a macroecological approach for the different lineages and by highlighting regions of higher lineage endemism and, consequently, high genetic diversity brings a contribution to think conservation actions for the clade that is threatened by habitat loss and environmental contamination of anthropic origin.
