Data from: Décalage temporel dans l’établissement des érables en forêt boréale révélé par une population marginale à la limite nordique de l’érable à sucre

A MSExcel spreadsheet including wood macrofossil charcoal data extracted from 25 mineral soil samples in site T70, located at the leading edge of sugar maple in the mixedwood ecotone.<br>## Description of the Data and file structure---Sheet 1-NChar - Number of charcoal particles recovered from each microsite. Dispositif: Indicates whether charcoal was extracted from soil collected in a systematic sampling (ERS) or targeted samplig (CIB); Microsite: a unique identifier for each soil sample in ERS or CIB; N_charcoal: the number of charcoal extracted from individual microsites.Sheet 2-Identification - Details of taxonomic identifications and radiocarbon datations. Dispositif: Indicates whether charcoal was extracted from soil collected in a systematic sampling (ERS) or targeted sampling (CIB); Microsite: a unique identifier for each soil sample in ERS or CIB; Sieve: the sieve from which the charcoal particles was retrieved (4mm or 2mm mesh-size); Sample ID: an arbitrary number (given for each individual particle recovered from a microsite at a given mesh-size); Charcoal ID: a unique identifier for each charcoal in the dataset; Mass: the mass of each individual charcoal particle before taxonomic identification (in mg); Notes (in french): some explanatory notes regarding features used for taxonomic identifications and/or taphonomic issues; Taxonomic ID: the taxonomic identifications (NA: not available); Mass2: the mass of charcoal material that was send for radiocarbon dating after taxonomic identification (in mg); Lab Number (UCIAMS; ULA): Laboratory number given by the Keck Carbon Cycle AMS Facility (UCIAMS) and Laboratoire de radiochronologie 14C du Centre d’études nordiques (ULA); 14C age: radiocarbon age and standard deviation (in years Before Present); 2σ-interval (and probability): the two-sigma interval of the calibrated date having the highest probability (in calibrated years Before Present) and associated probability; Median calibrated age: the median calibrated age (in calibrated years Before Present)
