“…Our genome-wide data corroborate previous mtDNA-based studies 4,6,26,55 in that Nearctic whimbrel populations are deeply differentiated from Palaearctic populations. Populations on the two continents also have a fixed difference in rump colouration 52,56 .…”

Intracontinental biotic divisions across the vast Palaearctic region are not well-characterized. Past research has revealed patterns ranging from a lack of population structure to deep divergences along varied lines of separation. Here we compared biogeographic patterns of two Palaearctic shorebirds with different habitat preferences, Whimbrel (Numenius phaeopus) and Eurasian curlew (N. arquata). Using genome-wide markers from populations across the Palaearctic, we applied a multitude of population genomic and phylogenomic approaches to elucidate population structure. Most importantly, we tested for isolation by distance and visualized barriers and corridors to gene flow. We found shallow Palaearctic population structure in subpolar bog and tundra-breeding whimbrels, consistent with other species breeding at a similarly high latitude, indicating connectivity across the tundra belt, both presently and during southward shifts in periods of global cooling. In contrast, the temperate grassland-breeding Eurasian curlew emerged in three distinct clades corresponding to glacial refugia. Barriers to gene flow coincided with areas of topographic relief in the central Palaearctic for whimbrels and further east for Eurasian curlews. Our findings highlight the interplay of historic and ecological factors in influencing present-day population structure of Palaearctic biota.

“…Speciation within the group was inferred to be recent, with current species diversity originating within the last 3 million years (Bridge et al 2005). Nearctic and Palearctic populations of the Sandwich Tern were long treated as conspecific due to their phenotypic similarity, but they were recently split as different species owing to their genetic divergence and the closer relationships of Nearctic populations to Elegant Tern than to Palearctic populations and to minute but likely diagnostic differences in plumage and structure (see Sangster et al 2011). Currently, the Palearctic Sandwich Tern is treated as a monotypic species by most authorities while the North American Cabot's Tern (formerly treated as a Nearctic subspecies of Sandwich Tern) includes the subspecies S. acuflavida acuflavida and S. a. eurygnatha (Cayenne Tern).…”

Multilocus barcoding confirms the occurrence of Elegant Terns in Western Europe

et al. 2016

We used sequences from one mitochondrial gene and from intronic regions of six nuclear loci to confirm genetically the presumed identity of four large terns with orange bill seen in Western Europe over the past decades. This multilocus genotyping ("multilocus barcoding") approach confirmed that one bird was a Lesser Crested Tern Sterna bengalensis as suspected based on its phenotype and identified the three other birds as pure Elegant Terns S. elegans. This last result was again in accordance with the appearance of these birds even if their identity had long been considered as unproven. In comparison with traditional (single-locus) barcoding, our approach allowed us to unambiguously exclude that these birds were first-generation hybrids or backcrosses involving Elegant Terns or other species of orange-billed terns.

“…Up to 1,000 Sandwich Terns were killed by the DWH spill (DWH NRDA Trustees 2016), and Louisiana populations are likely critical to the population as a whole. Three subspecies exist: one in Europe, one in the southern Caribbean, and one that breeds in Mexico, Greater Antilles, and the United States, including in Louisiana, T. s. acuflavidus; this subspecies is treated as a separate species (''Cabot's Tern'') by some (Sangster et al 2011).…”
