We wrote a Conversation article explaining what epigenetic ageing is, why dolphins are such a powerful study system, and what this research might tell us about ageing across social mammals.

Using decades of behavioural data from Shark Bay and epigenetic “ageing clocks”, we found that male dolphins with stronger social bonds are biologically younger than less social males of the same age.

It’s not about being in big groups: it’s the strength of relationships that matters.

🐬 Can friendship slow ageing?

In wild bottlenose dolphins, strong social relationships aren’t just important for social life — they may actually influence biological ageing.

If you need a happy science story today - another piece how male dolphins who bond better with their mates* age slower

@aunz.theconversation.com piece by @liviagerber.bsky.social @kjpeters.bsky.social and Lee Rollins

*Aussie dolphins, so the Aussie meaning of mates

New research out! 🐬

We tested 16 NZ toothed whale species to see if habitat predicts PFAS levels.

Results:
• Habitat = weak predictor
• Sex & age = stronger predictors
• Even remote oceans aren’t safe from PFAS

➡ Stranded archives can reliably calibrate epigenetic clocks 🔬

This opens exciting new pathways for population modelling, health assessments & long-term conservation.

Key findings:

• Accurate age estimates for dolphins ≤16 yrs

• Older 👵🏼 animals tend to be underestimated

• Dental 🦷 ageing error & decomposition? No detectable impact ❌

🌊🐬 New Paper Out! 🧬✨

We’ve developed the first ever epigenetic clock for common dolphins (Delphinus delphis) — using DNA from stranded & bycaught individuals to estimate age non-lethally and with high accuracy. A major step forward for dolphin conservation.

Just like polar bears in the Arctic, emperor penguins are the iconic species threatened by climate change in Antarctica 🐧

📣 Marine mammals are appearing far from their natural habitats. From belugas in rivers to walruses on boats. A new study, led by OceanCare, calls for better preparation to protect animals & communities as climate change drives these shifts.

Some OOH animals might be pioneers — testing new territory and potentially adapting to shifting environments. Should we rethink how we include them in conservation policy? 🧠🌍 #ClimateChange #Biodiversity

Managing OOH cases isn't just about the animals — it's also about public safety, ethical decision-making, and learning from rewilding and human-wildlife conflict. Education and communication are vital. #SciencePolicy #Conservation

What is an out of habitat (OOH) marine mammal? Think: a walrus on a French beach or a dolphin 🐬 in a freshwater river. Our paper sets out a definition, key drivers (like climate change & prey shifts), and what to do when they show up. #WildlifeConservation

📢 New paper alert! 🐋 As climate change reshapes our oceans, more marine mammals are turning up in unexpected places. We define "Out of Habitat" (OOH) animals, explore why it's happening, and what it means for conservation.
