Landsliding is a complex process that modifies mountainscapes worldwide. Its severe and sometimes long-lasting negative effects contrast with the less-documented positive effects on ecosystems, raising numerous questions about the dual role of landsliding, the feedbacks between biotic and geomorphic processes, and, ultimately, the ecological and evolutionary responses of organisms. We present a conceptual model in which feedbacks between biotic and geomorphic processes, landslides, and ecosystem attributes are hypothesized to drive the dynamics of mountain ecosystems at multiple scales. This model is used to integrate and synthesize a rich, but fragmented, body of literature generated in different disciplines, and to highlight the need for profitable collaborations between biologists and geoscientists. Such efforts should help identify attributes that contribute to the resilience of mountain ecosystems, and also should help in conservation, restoration, and hazard assessment. Given the sensitivity of mountains to land-use and global climate change, these endeavors are both relevant and timely.

The páramo region in the northern Andes is very biodiverse, presents high endemism and provides many ecosystem services. Unfortunately, the páramo is critically threatened by anthropogenic activities and climate change. Further research and development of efficient conservation strategies are therefore needed for the region, but they are often limited by the lack of consistent biological data-sources. Here we present VegPáramo (GIVD ID: SA-00-002, http://www.givd.info/ID/SA-00-002), a flora and vegetation database for the páramo based on phytosociological vegetation plots. VegPáramo contains data from 3,000 georeferenced vegetation plots with updated nomenclature. The database is accessible through the webportal http://www.vegparamo.com, from which floristic and vegetation data can be freely consulted and downloaded. This new tool should make future botanical and ecological páramo studies easier. VegPáramo is already geographically and floristically representative for the páramo region, but we hope it will continue to grow in scientific significance via new data addition and revision.
