However, how these differences influence climate regulation across Amazonian landscapes remains unclear. Using annual climate and land cover data and a spatial mixed-effects framework, we quantified PF\u2013SF contrasts in precipitation, evapotranspiration (ET), and land surface temperature (LST) across fractional forest cover gradients and SF successional stages in three Amazonian regions: central (CBA), eastern (EBA), and southern (SBA). PF\u2013SF contrasts varied markedly among climate variables, regions, successional stages, forest cover, and landscape contexts. Under standardized conditions, contrasts were generally smaller, and SF approached climatic conditions associated with PF, frequently exceeding PF in ET and exhibiting lower LST under moderate-to-high forest cover (&gt;50%). At high forest cover, SF exceeded PF in ET by up to ~100 mm and showed LST up to ~0.5 \u00b0C lower than PF. However, under current landscape configurations, contrasts were generally larger and more heterogeneous. In the EBA, SF exhibited up to ~365 mm lower precipitation than PF, particularly in early and intermediate successional stages, whereas in the SBA, advanced SF remained up to ~1.1 \u00b0C warmer than PF. Together, these findings indicate that climatic recovery during forest regeneration depends not only on succession and forest cover but also on the landscape contexts in which regeneration occurs. Furthermore, they suggest that SF could deliver substantially greater climatic benefits than currently observed across Amazonian landscapes when forest recovery is strategically planned and spatially targeted.<\/jats:p>","DOI":"10.1073\/pnas.2426400123","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T19:06:16Z","timestamp":1785783976000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":0,"title":["Landscape context constrains climate regulation recovery in Amazonian secondary forests"],"prefix":"10.1073","volume":"123","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4222-4953","authenticated-orcid":false,"given":"Lais","family":"Rosa-Oliveira","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0409dgb37","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Agricultural Engineering, Federal University of Vi\u00e7osa","place":["Vi\u00e7osa, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4169-3862","authenticated-orcid":false,"given":"Gabrielle","family":"Ferreira Pires","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0409dgb37","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Agricultural Engineering, Federal University of Vi\u00e7osa","place":["Vi\u00e7osa, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7708-4263","authenticated-orcid":false,"given":"Ricardo","family":"Gomes Tom\u00e1z","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0409dgb37","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Plant Pathology, Federal University of Vi\u00e7osa","place":["Vi\u00e7osa, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7668-1226","authenticated-orcid":false,"given":"Aline","family":"Pontes-Lopes","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04xbn6x09","id-type":"ROR","asserted-by":"publisher"}],"name":"Tropical Ecosystems and Environmental Sciences, National Institute for Space Research, S\u00e3o Jos\u00e9 dos Campos","place":["S\u00e3o Paulo, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5530-8473","authenticated-orcid":false,"given":"Livia","family":"Maria Brumatti","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0409dgb37","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Agricultural Engineering, Federal University of Vi\u00e7osa","place":["Vi\u00e7osa, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6874-9315","authenticated-orcid":false,"given":"Marcos","family":"Heil Costa","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0409dgb37","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Agricultural Engineering, Federal University of Vi\u00e7osa","place":["Vi\u00e7osa, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5654-5657","authenticated-orcid":false,"given":"Humberto Paiva","family":"Fonseca","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0409dgb37","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Agricultural Engineering, Federal University of Vi\u00e7osa","place":["Vi\u00e7osa, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4134-6708","authenticated-orcid":false,"given":"Luiz Eduardo Oliveira e Cruz de","family":"Arag\u00e3o","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04xbn6x09","id-type":"ROR","asserted-by":"publisher"}],"name":"Tropical Ecosystems and Environmental Sciences, National Institute for Space Research, S\u00e3o Jos\u00e9 dos Campos","place":["S\u00e3o Paulo, Brazil"]},{"id":[{"id":"https:\/\/ror.org\/03yghzc09","id-type":"ROR","asserted-by":"publisher"}],"name":"School of Geography, Faculty of Environment, Science and Economy, University of Exeter","place":["Exeter, United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-023-06970-0"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1029\/2021RG000766"},{"key":"e_1_3_4_3_2","unstructured":"Science Panel for the Amazon Amazon Assessment Report 2021.
