Summary

Genetic networks can characterize complex genetic relationships among groups of individuals, which can be used to rank nodes most important to the overall connectivity of the system. Ranking allows scarce resources to be guided towards nodes integral to connectivity. The greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern that breeds on spatially discrete leks that must remain connected by genetic exchange for population persistence. We genotyped 5,950 individuals, from 1,200 greater sage-grouse leks distributed across the entire species’ geographic range. We found a small world network composed of 458 nodes connected by 14,481 edges that are described here. The files associated with this data release [...]

Purpose

This genetic network was composed of hubs - i.e., nodes facilitating gene flow across the network - and spokes - i.e., nodes where connectivity is served by hubs. Using indices of network centrality, we identified hub nodes of greatest conservation importance. We also identified keystone nodes with elevated centrality despite low local population size. The loss of hub or keystone nodes could lead to the disintegration of the network into smaller, isolated sub-networks. Protecting both hub nodes and keystone nodes may conserve genetic diversity and could maintain network connections to ensure a resilient and viable population over time.

Revision History -- First release: February, 2018. Original title: "Sample collection information and microsatellite data used in a Network analysis of greater sage-grouse across the species range generated 2013 - 2016". Version 2.0: Released December, 2022. New title: "Genetic data and genetic network attributes for rangewide Greater Sage-grouse network constructed in 2018" -- In October 2022, the Bureau of Land Management asked for access to derived products associated with the publication (https://doi.org/10.1002/ece3.4056) that accompany this data release of genetic data. USGS realized that the dates of sample collection associated with this data release were incorrect (2013 - 2016) and should be 2006 - 2015. The data itself is correct, just the metadata needed to be corrected. USGS has made that correction and now the title of the metadata associated with the genetic data is "Sample collection information and microsatellite data for greater sage-grouse across the species range generated 2006 - 2015". We have also included associated products in this version 2.0 data release that were generated from the genetic data and thus renamed the data release "Genetic data and genetic network attributes for rangewide Greater Sage-grouse network constructed in 2018". Changes from previous version: 1) Corrected the dates of sample collection from 2013 - 2016 to 2006 - 2015 in the metadata for the genetic data. 2) Added derived products to the revised data release: genetic network minimum spanning tree edge attributes, edge attributes, and node attributes.
