What a great #FLFDevNet training course! Lots of new concepts & tips to help us be a better version of ourselves. A few I'm trying straight away...
1. ID 3 daily wins (gratitude)
2. Listen harder (let in the silence!)
3. ID key values
4. When questioning someone avoid "why"
5. Situational leadership

What a treat to have the new Editor in Chief for Fish and Fisheries, and all round fisheries-interdisciplinary-legend Kai Lorezen visit us at the @universityofessex.bsky.social today! Come again soon @fisheriesprof.bsky.social! And a very Happy Birthday to @dubucalexia.bsky.social! 🙌🐟🤗

So lovely to meet our new cohort of marine biology and ecology undergraduates @universityofessex.bsky.social. What a lovely bunch! And deff winning the highest jump there Michael Steinke!!

Salmon Whisperers....

Salmon Whisperers....
Atlantic salmon leaping up the Falls of Feugh. Exhausting even just watching them do it! We didn't see any make it to the top. Wonder if this dry summer has made it harder..... 😪

I'm so proud of my lab - they're growing up! 🥹 Weddings and babies, lecturer positions, international conferences and running complex field campaigns. And now with our latest sweet addition, we are three (OK maybe 2.5!) generations of #WomenInSTEM! #HeartFull

Cons of lenses vs. otos: the lens cores are tiny (hard to handle. Avoid coffee while dissecting!) and v.low mass (prob <0.1mg with both cores from 1 fish) requiring a good IRMS. Even so, some did fail (although unclear if bc of IRMS vs. me/droppage!)
Cons of either structure: lethal sampling (4/4)

Pros of lenses vs. otoliths: pulling off outer layers with forceps was quicker than embedding/sectioning; lots of labs can analyse bulk d13C cheaply and quickly. But both structures allow you to isolate the core when the fish was nourished by yolk (ie. avoiding 'contamination' by exogenous feeding)

Similar to using otolith core strontium concentrations or isotope ratios, elevated d13C values in the lens cores are seen in the offspring of anadomous mums as the result of vitellogenesis happening at sea (cf. FW for residents). 2/4 (photo credit: Uwe Kils, Wikipedia)

Disproportionate attention given to certain habitats (shallow, coral reefs), taxa (fish) and areas (N. Atlantic). Broad agreement on the need to integrate and apply methods better, to better understand connectivity drivers, and to increase sampling coverage and transnational/cross ecosystem networks

What a delight to meet Sam Ryder on the train today. I'm such a huge fan and he is the loveliest person. Keep spreading the kindness!! (And @samhairwolfryder.bsky.social if this is your account, thank you so much for the pic and not judging my clear over excitement!!!) Xx

This is v random but I often watch this lovely graphic (so pretty) but at the point in the year when it's just diff shades of red and white I cant stop thinking about the BBC news colours!

Wow. @universityofessex.bsky.social PhD students Lucy Smith & Izi Firth curated an amazing exhibition: #NaturesCanvas. Who knew our Life Sci dept housed so many talented artists? Glad to see so many #otoliths on display 🐟🥰! And a bell jar filled with crude oil to signify our hypoxia & ecotox work ☠️

Sometimes I worry that my work doesn't have enough impact. And then we do 1 school assembly to promote #WorldSharkDay & highlight the many types of marine sci careers (no you dont HAVE to be a diver or fisher) and I feel fulfilled & hopeful about the future. Thank you Broomgrove Juniors (& my kids!)

Great start to #FSBI2025 with a thought provoking Jack Jones lecture by Robert Rosell about reintroducing salmon into the River Lagan. Parallels to salmon fishing in the Yemen! Also v. proud of @peterbetts.bsky.social for his excellent talk on salmon metabolism across latitudinal gradients 👏

We made it!!! Didn't need the extra half hour walk after google maps took us to a locked gate, but lovely to be here! #FSBI2025 #FSBIGreenTravel

Second leg of our epic journey to #FSBI2025 complete! Now at the Sky Bar on the ferry in case anyone else is also on the Stena line! 🍻 Picked up @domino-joyce.fishsci.com.ap.brid.gy on our way! Full disclosure: had to sneak into an uber after missing the metro, but IT WAS ELECTRIC! #FSBIGreenTravel
