Our analysis shows that there has been a declining trend in NDVI in this region, with the strongest \u201cbrowning trend\u201d occurring in eastern Alaska where the climate during the growing season is relatively dry and warm. Possible reasons for the \"browning trend\" are decreased vegetation due to temperature-induced drought stress and increased infestations of insect pests.<\/jats:p>","DOI":"10.3390\/rs2122729","type":"journal-article","created":{"date-parts":[[2010,12,8]],"date-time":"2010-12-08T10:18:36Z","timestamp":1291803516000},"page":"2729-2747","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["The Browning of Alaska\u2019s Boreal Forest"],"prefix":"10.3390","volume":"2","author":[{"given":"Mary Beth","family":"Parent","sequence":"first","affiliation":[{"name":"Department of Forest Sciences, School of Natural Resources and Agricultural Sciences, University of Alaska Fairbanks, Fairbanks, AK 99775, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6887-3957","authenticated-orcid":false,"given":"David","family":"Verbyla","sequence":"additional","affiliation":[{"name":"Department of Forest Sciences, School of Natural Resources and Agricultural Sciences, University of Alaska Fairbanks, Fairbanks, AK 99775, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2010,12,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"928","DOI":"10.1016\/j.quascirev.2009.12.009","article-title":"An oxygen-isotope record of Holocene climate change in the south-central Brooks Range, Alaska","volume":"29","author":"Clegg","year":"2010","journal-title":"Quat.
