Species monitoring and conservation is increasingly challenging under current climate change scenarios. For the North Atlantic right whale (Eubalaena glacialis) this challenge is heightened by the added effects of complicated and uncertain past species demography. Right whales once had a much wider distribution across the North Atlantic Ocean, although the degree to which right whales in the western and eastern North Atlantic were genetically isolated remains unknown.We analyzed DNA from 24 4th-20th century (CE) right whale bone specimens that were collected from 10 historical and archaeological sites in Iceland, the Faroe Islands, and Scotland. Following mtDNA species identification, we obtained 15-locus nuclear microsatellite profiles from a subset of eight specimens and compared these to contemporary data from animals remaining in the western North Atlantic population. While some specimens share mtDNA haplotypes with the contemporary population, several new haplotypes were
A series of archaeological evaluations and excavations at Laigh Newton in East Ayrshire revealed evidence for intermittent occupation of this valley terrace between the Mesolithic and the Late Iron Age. The plough-truncated archaeology included the remains of a rectangular building and associated features of the mid-late fourth millennium BC, a more ephemeral structure and related pits of the mid third millennium BC, a charcoal-burning pit of the mid-first millennium AD and two other rectilinear structures of indeterminate date.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
