Peatlands provide a vital contribution to ecosystem services by their massive carbon storage and wide heterogeneity. However, monitoring, understanding, and disentangling the diverse vegetation traits from a heterogeneous landscape using complex RS signal is challenging, due to its wide biodiversity and distinctive plant species composition. In this work, we aim to demonstrate, for the first time, the large heterogeneity of peatland vegetation traits using well-established vegetation indices (VIs) and Sun-Induced Fluorescence (SIF) for describing the spatial heterogeneity of the signals which may correspond to spatial diversity of biochemical and structural traits. SIF originates from the initial reactions in photosystems and is emitted at wavelengths between 650\u2013780 nm, with the first peak at around 687 nm and the second peak around 760 nm. We used the first HyPlant airborne data set recorded over a heterogeneous peatland area and its surrounding ecosystems (i.e., forest, grassland) in Poland. We deployed a comparative analysis of SIF and VIs obtained from differently managed and natural vegetation ecosystems, as well as from diverse small-scale peatland plant communities. Furthermore, spatial relationships between SIF and VIs from large-scale vegetation ecosystems to small-scale peatland plant communities were examined. Apart from signal variations, we observed a positive correlation between SIF and greenness-sensitive VIs, whereas a negative correlation between SIF and a VI sensitive to photosynthesis was observed for large-scale vegetation ecosystems. In general, higher values of SIF were associated with higher biomass of vascular plants (associated with higher Leaf Area Index (LAI)). SIF signals, especially SIF760, were strongly associated with the functional diversity of the peatland vegetation. At the peatland area, higher values of SIF760 were associated with plant communities of high perennials, whereas, lower values of SIF760 indicated peatland patches dominated by Sphagnum. In general, SIF760 reflected the productivity gradient on the fen peatland, from Sphagnum-dominated patches with the lowest SIF and fAPAR values indicating lowest productivity to the Carex-dominated patches with the highest SIF and fAPAR values indicating highest productivity.<\/jats:p>","DOI":"10.3390\/rs11141691","type":"journal-article","created":{"date-parts":[[2019,7,17]],"date-time":"2019-07-17T02:44:03Z","timestamp":1563331443000},"page":"1691","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Hyplant-Derived Sun-Induced Fluorescence\u2014A New Opportunity to Disentangle Complex Vegetation Signals from Diverse Vegetation Types"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8657-3488","authenticated-orcid":false,"given":"Subhajit","family":"Bandopadhyay","sequence":"first","affiliation":[{"name":"Department of Meteorology, Pozna\u0144 University of Life Sciences, 60649 Poznan, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0953-7045","authenticated-orcid":false,"given":"Anshu","family":"Rastogi","sequence":"additional","affiliation":[{"name":"Department of Meteorology, Pozna\u0144 University of Life Sciences, 60649 Poznan, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9993-4588","authenticated-orcid":false,"given":"Uwe","family":"Rascher","sequence":"additional","affiliation":[{"name":"Institute of Biogeosciences, IBG2, Forschungszentrum Juelich GmbH, 52425 Juelich, Germany"}]},{"given":"Patrick","family":"Rademske","sequence":"additional","affiliation":[{"name":"Institute of Biogeosciences, IBG2, Forschungszentrum Juelich GmbH, 52425 Juelich, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7446-7752","authenticated-orcid":false,"given":"Anke","family":"Schickling","sequence":"additional","affiliation":[{"name":"Institute of Biogeosciences, IBG2, Forschungszentrum Juelich GmbH, 52425 Juelich, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7192-2032","authenticated-orcid":false,"given":"Sergio","family":"Cogliati","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, University of Milano-Bicocca, 20126 Milano, Italy"}]},{"given":"Tommaso","family":"Julitta","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, University of Milano-Bicocca, 20126 Milano, Italy"},{"name":"JB Hyperspectral Devices, Am Botanischen Garten 33, 40225 D\u00fcsseldorf, Germany"}]},{"given":"Alasdair","family":"Mac Arthur","sequence":"additional","affiliation":[{"name":"School of Geosciences, University of Edinburgh, Edinburgh EH9 3FF, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4283-2484","authenticated-orcid":false,"given":"Andreas","family":"Hueni","sequence":"additional","affiliation":[{"name":"Department of Geography, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6546-6459","authenticated-orcid":false,"given":"Enrico","family":"Tomelleri","sequence":"additional","affiliation":[{"name":"Faculty of Science and Technology, Free University of Bolzano, 39100 Bozen-Bolzano, Italy"}]},{"given":"Marco","family":"Celesti","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, University of Milano-Bicocca, 20126 Milano, Italy"}]},{"given":"Andreas","family":"Burkart","sequence":"additional","affiliation":[{"name":"JB Hyperspectral Devices, Am Botanischen Garten 33, 40225 D\u00fcsseldorf, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0901-9894","authenticated-orcid":false,"given":"Marcin","family":"Str\u00f3\u017cecki","sequence":"additional","affiliation":[{"name":"Department of Meteorology, Pozna\u0144 University of Life Sciences, 60649 Poznan, Poland"}]},{"given":"Karolina","family":"Sakowska","sequence":"additional","affiliation":[{"name":"Institute of Ecology, University of Innsbruck, Sternwartestrasse 15, 6020 Innsbruck, Austria"}]},{"given":"Maciej","family":"G\u0105bka","sequence":"additional","affiliation":[{"name":"Department of Hydrobiology, Faculty of Biology, Adam Mickiewicz University, 61614 Poznan, Poland"}]},{"given":"Stanis\u0142aw","family":"Rosadzi\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Hydrobiology, Faculty of Biology, Adam Mickiewicz University, 61614 Poznan, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1453-0374","authenticated-orcid":false,"given":"Mariusz","family":"Sojka","sequence":"additional","affiliation":[{"name":"Department of Land Improvement, Env.
