Plots were 20-by-15 m with 3 replicates per treatment. Summer fires were conducted during summer quiescence, fall fires after a <-2.2<sup>o</sup>C frost and spring fires when <em>Bouteloua gracilis</em> initiated growth. Current-year aboveground biomass was estimated annually by clipping four 0.25-m<sup>2</sup> quadrats from each plot during peak biomass. Biomass samples were dried to a constant weight at 60\u00b0C and weighed to the nearest 0.01 g before being separated into current and past years\u2019 growth and reweighed to determine current-year biomass as an estimate of productivity.</div><p></p>", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/47849860", "format": "xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "Oikos data.xlsx"}], "identifier": "10.15482/USDA.ADC/26349127.v1", "keyword": ["disturbance regime", "fire", "rangeland", "return interval", "seasonality", "semi-arid grassland"], "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2025-11-21", "programCode": ["005:040"], "publisher": {"@type": "org:Organization", "name": "Agricultural Research Service"}, "spatial": "{\"type\": \"Point\", \"coordinates\": [-105.950125, 46.399717]}", "temporal": "2008-07-15/2020-07-14", "title": "<b>Data from: Do species respond to multi-year disturbance rhythms and are we missing the beat?</b>"}
