“…In addition, the results presented here indicate further population structuring within the tropical and temperate clades, and we recommend that future studies further examine this hypothesis within both the southern and northern hemispheres. Modern advancements in high throughput sequencing such as RAD-seq and exon capture can explore the within-clade spatial structure and has proven useful in species delimitation and phylogenies within recently and rapidly diverged groups (Arrigoni et al, 2020;Cowman et al, 2020;Grinblat et al, 2021;Wepfer et al, 2020). Concurrent research on symbionts and reproductive biology may also provide additional valuable lines of evidence to help understand the level of diversity within Plesiastrea.…”
