Nuclear_plastid_microsatellite_SSR_Dicorynia_guianensis_French_Guiana_4samplingsites

This dataset comprises three comma-separated (CSV) files providing individual-level genotypic and ecological data for 1,528 Dicorynia guianensis trees sampled across four natural populations in French Guiana (Sparouine, n = 367; Paracou, n = 360; Nouragues, n = 383; Regina, n = 418). The file tree_metadata.csv contains individual identifiers (ID), population name (plot), GPS coordinates (decimal degrees, WGS84), and diameter at breast height (DBH, in cm; range: 0.3–143.3 cm) for all 1,528 sampled individuals. The file nSSR_4sites_data_frame.csv contains biallelic nuclear microsatellite genotypes for 1,512 individuals at 66 loci (132 allele columns, two per locus, coded as fragment length in base pairs). Loci are named following the SSRSeq_GMANAGE_UDI scheme developed in Lepais et al. (2020). The file chlrSSR_4sites_data_frame.csv contains plastid marker genotypes for all 1,528 individuals at 26 loci, including 2 single nucleotide polymorphisms (SNPs) and 24 microsatellite loci (19 mononucleotide repeats, 5 dinucleotide repeats), all haploid and maternally inherited.
