Resumen:

We used ecological niche modeling and place prioritization procedures to identify areas for conservation and restoration for the Neotropical river otter, Lontra longicaudis annectens Major 1897, in central Mexico. This species is highly sensible to fluvial ecosystem degradation, and large areas of the Apatlaco-Tembembe basin fluvial ecosystems have been highly transformed. We selected ecological indicators (EI) from literature and own field work to determine variables best describing the fluvial ecosystem degradation, relating them to the species' presence or absence. Field data of EI, species records, and digital thematic information of hydrology, geomorphology and climate were used in ResNet Place Prioritization algorithm for the selection of potential conservation and restoration areas. We generated a spatial model considering a hierarchy of key areas based on river otter's ecological niche requirements and habitat ad hoc conditions for the species permanence. This allowed identifying areas to be included in landscape management plans for conservation and restoration. The sequential integration of specie? potential distribution and place prioritization modeling allows merging biodiversity conservation and ecological restoration strategies at different ecological scales, helping adaptive management in land planning to be more flexible and feasible. © 2009 by Nova Science Publishers, Inc.
