When Publishers use forced italics (e.g. 𝑖𝑡𝑎𝑙𝑖𝑐𝑠) in their social media posts, it makes the content less #accessible. You have a duty of care to your audience. Please stop.

Scientists warn escaped farmed salmon could interbreed with wild fish, further endangering Scotland’s fragile populations.

After the calamitous news last week that 75,000 farmed #salmon had escaped in #Scotland, I wrote this Conversation article exploring why this is such bad news and what it means for wild salmon: doi.org/10.64628/AB.... #Environment #Aquaculture #FishFarming #Fish #Pollution #Genetics

The last leg of yesterday's #FSBIGreenTravel, crossing the Irish Sea, quick stop in Dublin and then up north! Such a smooth trip, and a new found love of ferries. The perfect start to #FSBI2025!

#FSBI2025 here we come! Roped my lovely students into this long journey from Essex to Belfast! Walked to Wivenhoe station & now on train to Liverpool to get ferry. Wish us luck! Remember to add your own green travel stories/efforts (however small) to tinyurl.com/FSBIGreenTravel 🐟🚄⛴️ #FSBIGreenTravel

The #FSBIGreenTravel to #FSBI2025 continues after a pit stop in Bangor, spending a wonderfully raucous evening with dear friend and colleague, Gary Carvalho! Treated to a bounty of vegetarian dishes. Produce which was in the garden 5 mins before. Now a quick train to Holyhead and the ferry awaits!

On my way to #FSBI2025 in Belfast, and my #FSBIGreenTravel is well underway! The first leg involves a journey from #Cardiff to #Bangor. After making my way through a sea of bucket hats, with the aftermath of Oasis' opening night in Cardiff, I'm on one of Transport for Wales' new, greener trains!

With only two more sleeps until #FSBI2025, remember to tell us all about your #FSBIGreenTravel to the symposium! We'll collate and share our favourite stories and will announce three winners at the banquet! To enter, fill in the following: tinyurl.com/FSBIGreenTravel Safe travels!
