7. Overview of the data (abstract): 

Partially clonal species are subject to the same evolutionary forces experienced by obligately sexual species, but the variety of potential responses at the population level is much more diverse, ranging from inbreeding to a loss of sexual reproduction. These responses have different genetic outcomes and can interact with each other and other species-level characteristics, such as dispersal and lifespan, to influence the genotypic and genetic diversity of populations through time and across a species range. In this study, we compared the historical and modern population genetics of Vaccinium vitis-idaea (lingonberry) samples from a warm range edge region of the species’ circumboreal distribution. Using 18 polymorphic microsatellite loci in 261 historical and modern samples, we answered three questions: 1) Has genetic diversity been lost through the last six decades?, 2) Do modern populations show signs isolation or low differentiation?, and 3) What are the genotypic and genetic signals of clonality in modern populations? Lingonberry currently appears to be genetically robust at a warm range edge. This study also reveals the variety of reproductive strategies a partially clonal species and can display within a small area, and lays the groundwork for long-term monitoring of geographically proximate populations with vastly different levels of clonal vs. sexual reproduction in region experiencing significant warming.

DATA & FILE OVERVIEW

---------------------

***General Information Files***

Sample_Information.xlsx - this file provides all basic sample information, such as geographical location, date of collection, and sample IDs

Herbarium Appendix.docx - this file contains photographs and information for all herbarium samples obtained for this study (including samples that did not make it to the final analysis due to DNA extraction failures)


***Genetic Data Files***

All genetic data is formatted for the GenoDive program. Once loaded into that program, the data can be converted to a multitude of different formats. Data files include the following: 

H_M_clonecorrected_genodive.xlsx - Data at 8 microsatellite loci for herbarium and modern samples, clone corrected (duplicates removed)

H_M_W_C_clonecorrected_genodive.xlsx - Data at 8 microsatellite loci for herbarium, modern, wild, and cultivated samples, clone corrected (duplicates removed)

Modern_all_genodive.xlsx - Data at 18 microsatellite loci for all modern samples

Modern_clonecorrected_genodive.xlsx - Data at 18 microsatellite loci for clone corrected modern data (duplicates removed)
