Greetings MARMAM! Join us on *19 August 2021 at 6 PM Pacific Time (**August 20th at **1 AM UTC / 10:30 AM ASCT)* for the next SMM Seminar Editor's Select Series: Population genomic structure of killer whales (*Orcinus orca*) in Australian and New Zealand waters with Isabelle Reeves of Flinders University. Free to attend. Registration required. Presented online on Zoom. Register here: https://us06web.zoom.us/webinar/register/WN_CqOz80alTrqdJ-FopiQljw Space on Zoom is limited to the first 100 attendees. The talk will also be streamed live on the SMM Facebook page <https://www.facebook.com/marinemammalogy>. *The SMM Seminar Editor's Select Series highlights the latest and most exciting marine mammal science published in the Marine Mammal Science Journal. This is your chance to engage with marine mammal scientists, learn and ask questions from anywhere in the world. All are welcome. * *About this talk:* In Australasia, seasonal killer whale aggregations have been recently discovered and they have known to also reside year-round in New Zealand waters. However, there is currently limited information available about the species in these regions and therefore effective conservation management strategies are lacking. Here, we present the first study on the number of killer whale populations and their connectivity in Australasia using DNA. We discovered a minimum of three populations of killer whales, one in tropical and a second in temperate Western Australia, and a third in New Zealand. They each have distinct female-driven societies and appear to have little movement between them with low number of breeders. These findings can assist conservation management of these animals in the region. *About the presenter: * Isabella is currently a PhD Candidate in the Cetacean Ecology, Behaviour and Evolution Lab and the Molecular Ecology Lab at Flinders University in South Australia. She has over five years of experience researching cetaceans, leading her to obtain a skillset predominantly in photo-identification methods and using genetics to understand population-level questions for conservation. Her research now focusses on using genetics to broadly understand cetacean evolution, with a focus on Australasian killer whales.
