New paper alert 🚨

A study led by #CPGSthlm researchers found DNA from a bear in 9.6k year old lake sediments. This potentially rewrites the history of brown bears in Scandinavia! 🧬🐻🐾🏔️🧊

Very excited to share our study of an ancient environmental genome extracted from lake sediment! It originates from a brown bear that lived around 9,600 years ago close to the last ice-sheet remains in northern Sweden, and has an unexpected mitochondrial haplogroup. 1/7 www.pnas.org/doi/10.1073/...

Post-Doctoral Research Fellow in Ancient Environmental DNA:Whiteknights Reading UK We are seeking a highly motivated Post-Doctoral Research Fellow to join our research team at Reading, focusing on sedimentary DNA (sedaDNA / environmental DNA) from soils and sediments from the project’s case study regions in Spain and North Africa. You will contribute to the reconstruction of past landscapes and human-environment interactions through the analysis of sedimentary DNA. This includes analysing samples from terraces, irrigated fields and archaeological sites, and using eDNA metagenomics and metabarcoding approaches for multi-species detection, with the aim of characterising changing plant and animal species diversity and richness over time. The position will involve fieldwork, laboratory work, data analysis, and collaboration with an interdisciplinary team of archaeologists, palaeoecologists and historians.
