Heredity Podcast

In this second of our special episodes on the 2024 PopGroup conference, we hear from Mark Kirkpatrick, who gave the plenary talk which was the climactic end to the meeting. Mark tells us why he loves Popgroup, what his conference talk was about and what questions he's excited to dig into next.

PopGroup is the beloved annual meeting of the Population Genetics group of the Genetics Society. This episode we hear from Mike Richie, lead organiser at this year's host organisation - the University of St Andrews, from plenary speaker Susan Johnston and from student prizewinner Diana Lobo.

Each year Heredity awards a prize for the best student paper in the journal, this episode Ellen Nikelski, talking about her paper and how it feels to have been the winner in 2023.

One of the big decisions in planning a genetic study is what kind of sequencing approach to use. This episode we talk to Daria Martchenko and Aaron Shafer (Trent University, Canada), whose paper compares and contrasts whole genomes to RADseq in a study of mountain goat demography and adaptive history.

We tend to focus on research studies on the podcast, but review papers are a hugely important part of the scientific literature. This week we talk to Frank Hailer, reviews editor, who demonstrates his passion for using genetics in his work and talks about why he loves his job at Heredity.

Barriers to gene-flow control population connectivity, but what barriers exist in the sea? How similar is the connectivity of island marine organisms to those on land? As with many evolutionary questions, the Galapagos is the perfect place to find answers. Max Hirschfeld and Christine Dudgeon discuss their new work with the Galapagos bullhead shark.

What is effective population size (Ne), and why is it important? Robin Waples takes us back to the basics of this important evolutionary concept and discusses his new paper, using simulations to demonstrate that Bill Hill's 1972 equation for calculating Ne still works for populations with extreme reproductive patterns.

Kamolphat Atsawawaranunt and Anna Santure discuss how they have used diverse samples of DNA to trace the introduction history of the common myna from its native range across its invasive distribution in the Pacific.

In this episode, Richard Bernstein (Institute for Bee Research Hohen Neuendorf) discusses the development of the first genomic prediction model for honey bees. Genomic prediction is well established in the breeding of many commercial species, but wasn’t possible in honey bees until now. Richard fills us in on what genomic prediction actually is, why its useful and why prediction for bees is so tricky.

In this episode, Prof Thomas Madsen (Deakin University) discusses how a long-term study of an adder population has provided evidence that polyandry and non-random fertilisation can have positive effects on genetic diversity. Thomas argues that factoring in mating dynamics could help to improve conservation genetic analyses.
