title: Data from: Think globally, breed locally: Limited genetic impact of management in solitary bees (<em>Osmia cornuta</em> and <em>Osmia bicornis</em>)

description: This dataset contains multilocus genotype data for two solitary bee
 species, Osmia cornuta and Osmia bicornis, generated using 11
 microsatellite markers. All specimens were collected in Switzerland and
 include both contemporary samples collected in 2023 and historical
 specimens collected between 1990 and 2000 from Swiss entomological
 collections. For a subset of individuals, the dataset also reports the
 NCBI accession numbers of mitochondrial DNA sequences (COI region)
 generated as part of this study. These data enable comparisons of genetic
 variation and population structure between O. cornuta and O. bicornis, as
 well as between historical and contemporary populations, using a common
 set of neutral genetic markers.

 Description of the data and file structure The genetic data were generated
 to support a spatio-temporal analysis aimed at assessing the effects of
 *Osmia* spp. management practices in Switzerland. Samples were collected
 from three distinct sampling sites across the country and include both
 contemporary field-collected specimens and historical museum specimens
 accessed through several Swiss natural history museum collections. ###
 Files and variables #### File: Osmia_bicornis-contemporary.xlsx
 **Description:**  ##### Variables * **sample_ID**: code to identify each
 sample. * **Nest:** Identifier of the artificial nest from which each bee
 was sampled. “n/a” indicates that the sample was not collected from a
 placed trap nest but was provided by a commercial breeder (BREEDER1 or
 BREEDER2) from managed *Osmia* spp. populations. * **Sampling area**:
 where the trap nest was located. * **MtDNA seq:** Name assigned to each
 mitochondrial (mtDNA) sequence generated in this study and used in the
 analyses and publication. “n/a” indicates that mitochondrial DNA was not
 sequenced for that specimen. * **GenBank:** Accession number of each
 sequence deposited in GenBank, through which the sequence can be accessed
 and downloaded. “n/a” indicates that no mitochondrial sequence was
 generated for that specimen. * **Obic-1374, Obic-168, Obic-1181, Obic-629,
 Obic-73, Obic-740, Obic-1206, Obic-220, Obic-95, Oru-S8, Oru-E5**:
 Microsatellite markers used to genotype the bees. For each marker, both
 alleles are reported. A value of “0” indicates that the locus did not
 amplify and that both allele values are missing. #### File:

 **ind_ID**: code to identify each sample. * **GBIF/identification
 number**: GBIF number of identifying information of each specimens to
 gather information regarding where and when it has been sampled and in
 which collection it is housed. * **Sampling area**: where the specimen was
 sampled. * **MtDNA seq:** Name assigned to each mitochondrial (mtDNA)
 sequence generated in this study and used in the analyses and publication.
