The effective population size – and why it matters Since the Kunming-Montreal Global Biodiversity Framework was adopted in 2022, β€œmaintaining and restoring genetic diversity” in wild species is on the global agenda. The headline indicat…

Effective population size is a key ingredient in indicators used to monitor genetic #biodiversity – and a fundamental concept in population genetics.

But what is it, really? 🧬 We try to explain in our new blog post ⬇️

Finally published! We first uploaded this preprint in 2022 but dropped it after frustrating reviews.
It was well received and cited, motivating us to revisit it.
We added new content, including simulations and a proof-of-concept genomic green status assessment.

This recently-accepted study highlights the critical need to incorporate genomic erosionβ€”the loss of genetic diversity, accumulation of harmful mutations, maladaptation, and introgressionβ€”into conservation assessments.

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.

Built up over time, resistant to decay, deeply interesting to just a small number of people." A yellow slime mold stretching out and exploring. "Our love is like a slime mold. Collaborative, complex, at times unnerving to behold." A piece of limestone with a small trilobite in the corner. "Our love is like limestone. Layered, useful for many purposes, shaped by the friends we met along the way." A ring-billed gull with a french fry on a beach. "Our love is like a ring-billed gull. Abundant, found in North America, sometimes sustained by french fries." An Atlantic horseshoe crab walking on the sand. "Our love is like a horseshoe crab. Tough, timeless, unrelated to true crabs." A drawing of the phosphorus cycle, with arrows connecting various parts of a scene, including algae and fish and a farm and a river and a forest. "Our love is like the phosphorus cycle. Important, really hard to draw."
