Sample collection was carried out in 12 different sampling occasions and in three Italian regions (Sicily, Umbria and Lazio). A total number of 53 sites, characterised by different stages of A. altissima colonisation, were sampled. carbon-13 nitrogen-15 BODC parameter semantic model chemical substances invasive alien species Biodiversity Thesaurus stable isotope Environmental Thesaurus cc-by https://creativecommons.org/licenses/by/4.0/ Info and download page on LifeWatch Italy Data Portal https://data.lifewatchitaly.eu/handle/123456789/326244 Sampling occurred in three Italian regions and, specifically, 50 sites were sampled in Sicily, two in Umbria and one in Lazio. 11.928050 14.490257 42.778224 36.748910 2023-06-09 2025-06-13 Species Ailanthus altissima https://www.checklistbank.org/dataset/312578/taxon/BCBF Species Alcea rosea https://www.checklistbank.org/dataset/312578/taxon/BH8Y Species Arundo pliniana https://www.checklistbank.org/dataset/312578/taxon/H3NT Species Capparis spinosa https://www.checklistbank.org/dataset/312578/taxon/QS24 Species Celtis australis https://www.checklistbank.org/dataset/312578/taxon/5XGKD Species Fraxinus ornus https://www.checklistbank.org/dataset/312578/taxon/6JMH8 Species Nerium oleander https://www.checklistbank.org/dataset/312578/taxon/4768L Species Olea europaea https://www.checklistbank.org/dataset/312578/taxon/493JT Species Pennisetum setaceum https://www.checklistbank.org/dataset/312578/taxon/S5KP Genus Phillyrea https://www.checklistbank.org/dataset/312578/taxon/8WJR6 Species Phillyrea latifolia https://www.checklistbank.org/dataset/312578/taxon/4G6YZ Genus Pinus https://www.checklistbank.org/dataset/312578/taxon/C84WJ Species Pistacia lentiscus https://www.checklistbank.org/dataset/312578/taxon/77MK8 Genus Quercus https://www.checklistbank.org/dataset/312578/taxon/8W2YL Species Quercus ilex https://www.checklistbank.org/dataset/312578/taxon/793PC Species Quercus pubescens https://www.checklistbank.org/dataset/312578/taxon/4R5VW Species Rhus typhina https://www.checklistbank.org/dataset/312578/taxon/4SND6 Genus Robinia https://www.checklistbank.org/dataset/312578/taxon/9CLYF Species Rosa canina https://www.checklistbank.org/dataset/312578/taxon/4TCZM Genus Rubus https://www.checklistbank.org/dataset/312578/taxon/643JJ Species Solanum lycopersicum https://www.checklistbank.org/dataset/312578/taxon/4Y369 Genus Tilia https://www.checklistbank.org/dataset/312578/taxon/7WX3 Genus Ulmus https://www.checklistbank.org/dataset/312578/taxon/84MS Species Vitis vinifera https://www.checklistbank.org/dataset/312578/taxon/5BM7B http://www.w3.org/ns/dcat#keyword http://data.loterre.fr/ark:/67375/BLH-SQMKT4H5-7 http://www.w3.org/ns/dcat#keyword http://vocabs.lter-europe.net/EnvThes/20310 http://www.w3.org/ns/dcat#keyword http://vocab.nerc.ac.uk/collection/S27/current/CS002837/ http://www.w3.org/ns/dcat#keyword http://vocab.nerc.ac.uk/collection/S27/current/CS002808/ Marco Lauteri National Research Council (CNR), Research Institute on Terrestrial Ecosystems (IRET) Research Director marco.lauteri@cnr.it 0000-0003-1071-7999 LifeWatch Italy lifewatchitaly@gmail.com Marco Lauteri National Research Council (CNR), Research Institute on Terrestrial Ecosystems (IRET) Research Director marco.lauteri@cnr.it 0000-0003-1071-7999 Point Of Contact Marco Ciolfi National Research Council (CNR), Research Institute on Terrestrial Ecosystems (IRET) Technologist marco.ciolfi@cnr.it 0000-0003-4831-8053 Point Of Contact USEit_StableIsotopeData_SoilSamples_20251106.csv USEit_StableIsotopeData_SoilSamples_20251106.csv 11841 MD5:beafb7fba3eb4790cfe918d0f0303ebf 1 column , catalogNumber Catalog Number An identifier (preferably unique) for the record within the data set or collection.
