The purpose of this study was to assess to what extent the position of the tropical EATL (9\u00b0N\u201318\u00b0S) is in near-equilibrium with the climate, which determines its potential to adapt to climate change. On a continental scale, we have used land cover maps (MODIS MCD12) and elevation data (SRTM) to make the first-order assessment of the EATL position and continuity. For the assessment on a local scale and to address the three-dimensional nature of environmental change in mountainous environments, a novel method of automated delineation and assessment of altitudinal transects was devised and applied to Landsat-based forest maps (GLAD) and fine-resolution climatology (CHELSA). The emergence of a consistent longitudinal gradient of the treeline elevation over half of the EATL extent, which increases towards the equator by ~30 m and ~60 m per geographic degree from the south and north, respectively, serves as a first-order validation of the approach, while the local transects reveal a more nuanced aspect-dependent pattern. We conclude that the applied dual-scale approach with automated mass transect sampling allows for an improved understanding of treeline dynamics.<\/jats:p>","DOI":"10.3390\/rs15102679","type":"journal-article","created":{"date-parts":[[2023,5,22]],"date-time":"2023-05-22T02:00:27Z","timestamp":1684720827000},"page":"2679","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Establishing the Position and Drivers of the Eastern Andean Treeline with Automated Transect Sampling"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0442-2529","authenticated-orcid":false,"given":"Przemyslaw","family":"Zelazowski","sequence":"first","affiliation":[{"name":"Centre of New Technologies, University of Warsaw, 02-097 Warsaw, Poland"}]},{"given":"Stefan","family":"Jozefowicz","sequence":"additional","affiliation":[{"name":"Centre of New Technologies, University of Warsaw, 02-097 Warsaw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3618-1144","authenticated-orcid":false,"given":"Kenneth J.","family":"Feeley","sequence":"additional","affiliation":[{"name":"Department of Biology, University of Miami, Coral Gables, FL 33156, USA"}]},{"given":"Yadvinder","family":"Malhi","sequence":"additional","affiliation":[{"name":"Environmental Change Institute, School of Geography and the Environment, University of Oxford, Oxford OX1 3QY, UK"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"853","DOI":"10.1038\/35002501","article-title":"Biodiversity Hotspots for Conservation Priorities","volume":"403","author":"Myers","year":"2000","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"61","DOI":"10.3389\/feart.2020.00061","article-title":"Observed and Projected Hydroclimate Changes in the Andes","volume":"8","author":"Arias","year":"2020","journal-title":"Front.
