And in case you’re curious… here is what blow sampling a humpback whale looks like! 🐋 We closely monitor behavioural responses & work hard to develop increasingly less invasive ways of collecting DNA from whales 🧬 #consgen #PopGen #MarMam

Last month I had the immense privilege of travelling to Kalaallit Nunaat to train a wonderful team in drone-based blow sampling of large whales 🐋 An unforgettable experience, we travelled through these beautiful fjords searching for whales to collect blow, biopsy & eDNA 🧬 Qujanaq! #consgen #PopGen

I'm looking forward to presenting my findings on the spatio-temporal genetic structure of humpback whales feeding in the North Pacific over the past 4 decades from my postdoc at the Marine Mammal Institute @oregonstate.edu at the European Cetacean Society (ECS) conference in Scotland next week. 🐳🧬

Great to be in Kaunas, Lithuania, as part of the #GENOA Cost Action: working towards integrating genetic diversity indicators in species assessments to protect #biodiversity. 🧵
A powerpoint slide from the opening talk showing the mission statement of GENOA which reads "The main aim and objective of the GENOA is to implement genetic diversity indicators to broaden the uptake and use of genetic diversity for species assessments to protect biodiversity."Another slide from the opening talk showing some statistics on the GENOA members, including the gender balance (women 54%, male 45%, prefer not to say 2%) and that 44 countries are represented by members.

If Europe wants real energy security, the answer isn’t more LNG terminals or new gas deals. It’s: ✅ cutting fossil fuel demand ✅ scaling up renewables, grids and storage ✅ electrifying heating & transport ✅ insulating homes

Humpback whales cast bubble nets to catch prey. They may be learning from each other
Humpback whales will sometimes use an intricate strategy to catch food called bubble-net feeding. A new study suggests they're spreading the knowledge of how to do it to each other.
