Recent findings from the Luquillo Mountains, Puerto Rico, have raised questions about whether erosion rates that vary due to past tectonic events and are spatially patterned in relation to elevation may drive vegetation patterns along elevation gradients. Here we use airborne light detection and ranging (LiDAR) technology to observe forest height over the Luquillo Mountain Range. We show that models with different functional forms for the two prominent bedrock types best describe the forest height-elevation patterns. On one bedrock type there are abrupt decreases in forest height with elevation approximated by a sigmoidal function, with the inflection point near the elevation of where other studies have shown there to be a sharp change in erosion rates triggered by a tectonic uplift event that began approximately 4.2 My ago. Our findings are consistent with broad geologically mediated vegetation patterns along the elevation gradient, consistent with a role for mountain building and deconstructing processes.<\/jats:p>","DOI":"10.3390\/rs8100864","type":"journal-article","created":{"date-parts":[[2016,10,20]],"date-time":"2016-10-20T10:15:49Z","timestamp":1476958549000},"page":"864","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Abrupt Change in Forest Height along a Tropical Elevation Gradient Detected Using Airborne Lidar"],"prefix":"10.3390","volume":"8","author":[{"given":"Jeffrey","family":"Wolf","sequence":"first","affiliation":[{"name":"Department of Ecology, Evolution and Environmental Biology, Columbia University, New York, NY 10027, USA"}]},{"given":"Gilles","family":"Brocard","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, University of Pennsylvania, Philadelphia, PA 19104, USA"},{"name":"School of Geosciences, Faculty of Science, The University of Sydney, Camperdown NSW 2006, Australia"}]},{"given":"Jane","family":"Willenbring","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, University of Pennsylvania, Philadelphia, PA 19104, USA"},{"name":"Geosciences Research Division, Scripps Institution of Oceanography, University of California, La Jolla, CA 92093, USA"}]},{"given":"Stephen","family":"Porder","sequence":"additional","affiliation":[{"name":"Department of Ecology and Evolutionary Biology, Brown University, Providence, RI 02916, USA"}]},{"given":"Mar\u00eda","family":"Uriarte","sequence":"additional","affiliation":[{"name":"Department of Ecology, Evolution and Environmental Biology, Columbia University, New York, NY 10027, USA"}]}],"member":"1968","published-online":{"date-parts":[[2016,10,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3171","DOI":"10.1111\/j.1365-2486.2010.02323.x","article-title":"Introduction: Elevation gradients in the tropics: Laboratories for ecosystem ecology and global change research","volume":"16","author":"Mahli","year":"2010","journal-title":"Glob.
