Looks can be deceiving: speciation dynamics of co-distributed Angophora (Myrtaceae) species in a varying landscapeSusan Rutherford, Justin Wan, Joel Cohen, Doug Benson & Maurizio Rossetto
Understanding the mechanisms underlying species divergence remains a central goal in evolutionary biology. Landscape genetics can be a powerful tool for examining evolutionary processes. We used genome-wide scans to genotype samples from populations of eight Angophora species. Angophora is a small genus within the eucalypts comprising common and rare species in a heterogeneous landscape, making it an appropriate group to study speciation. We found A. hispida was highly differentiated from the other species. Two subspecies...
Spatial, climate and ploidy factors drive genomic diversity and resilience in the widespread grass Themeda triandraCollin Ahrens, Elizabeth A. James, Adam D. Miller, Ferguson Scott, Nicola C. Aitken, Ashley W. Jones, Patricia Lu‐Irving, Justin O. Borevitz, David J. Cantrill & Paul D. Rymer
This data set was used to assess the climate resilience of Themeda triandra, a foundational species and the most widespread plant in Australia, by assessing the relative contributions of spatial, environmental, and ploidy factors to contemporary genomic variation. Reduced-representation genome sequencing on 472 samples from 52 locations was used to test how the distribution of genomic variation, including ploidy polymorphism, supports adaptation to hotter and drier climates.
