Seed sourcing in the genomics era: multispecies provenance delineation for current and future climates

Restoration interventions require knowledge on the suitability of seed sources. Provenance delineation for ecological restoration degraded environments has begun to incorporate genome-wide information adaptive variation, but this only been completed a small number plant species. Rarely is provenance using genomics approach applied species occurring across different habitats, and in context future climate scenarios, despite their potential importance successful long-term restoration. Here, we use neutral genetic data investigate patterns differentiation landscape model putatively variation under multiple scenarios two co-occurring predominantly mesic environment, semi-arid environment. We then determine similarity sourcing locations hypothetical sites, both current scenarios. found that geographical extent provenances amount change required track projected climatic conditions over time differed within pairs species, between habitats. Additionally, had differing effects landscapes indicating differential response changing from arid This implies guidelines can be habitat dependent. discuss how these results utilized design strategies restoration, methods could more broadly delineate other locations.
