Having a suite of predefined biophysical regions at a variety of scales that correspond to differences in plant productivity and phenology would allow analysts to select a set of analysis units at the scale needed. In other cases, environmental or social responses may be hypothesized to be related to differences in plant dynamics. One may compare the discrimination in such data that biophysical regions at different scales provide to determine which best distinguishes the responses in question, such that like responses fall within the same regions to the degree possible. If those relationships are significant, the responses may then be extrapolated based on the biophysical regions. I defined hierarchical biophysical regions based on plant productivity and phenology by clustering global 0.083 degree resolution normalized difference vegetation indices (NDVI) over a 10\u00a0year period. Agglomerative average\u2010linkage distances based on squared error between clusters were conducted using an iterative sampling approach to merge more than 2 million clusters into fewer and fewer clusters based on NDVI greenness profiles comprised of 240 values over 10\u00a0years, until all cells were in a single cluster. Greater and greater differences in greenness profiles were ignored at higher levels of the hierarchy. Using a difference increment of 0.1, 253 non\u2010duplicative sets of clusters were created, and 107 of those were included in animations that may be used to explore differences in global plant dynamics. Differences in clusters were quantified based on comparing the focal set of cluster results with 10 other cluster sets. Analysts may use the hierarchical clusters to improve the alignment of their parameter sets that inform plant growth and other dynamics with real\u2010world plant dynamics.<\/jats:p>","DOI":"10.1111\/gcb.15070","type":"journal-article","created":{"date-parts":[[2020,3,7]],"date-time":"2020-03-07T21:49:37Z","timestamp":1583617777000},"page":"3689-3697","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Hierarchical global plant biophysical regions as potential analysis units"],"prefix":"10.1111","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3362-2976","authenticated-orcid":false,"given":"Randall B.","family":"Boone","sequence":"first","affiliation":[{"name":"Natural Resource Ecology Laboratory and the Department of Ecosystem Science and Sustainability Colorado State University Fort Collins CO USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,4,6]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/sdata.2018.40"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.sste.2013.04.004"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1475-2743.2008.00169.x"},{"issue":"4","key":"e_1_2_6_5_1","doi-asserted-by":"crossref","first-page":"e0126430","DOI":"10.1371\/journal.pone.0126430","article-title":"Mapping forest fuels through vegetation phenology: The role of coarse\u2010resolution satellite time\u2010series","volume":"10","author":"Bajocco S.","year":"2015","journal-title":"PLoS ONE"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0889.2006.00210.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.3390\/rs5094229"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/gcb.13995"},{"issue":"6","key":"e_1_2_6_9_1","first-page":"737","article-title":"Generalizing El Ni\u00f1o effects upon Maasai livestock using hierarchical clusters of vegetation patterns","volume":"66","author":"Boone R.
