One year ago, my life took a horrible turn. While attending a conference in Spain, I was hit by #GuillainBarreSyndrome. I just drafted some of my story, hoping for cathartic release during this sad anniversary. I share it in case it can help someone: rb.gy/dgt6og

📣 Just published in @conphysjournal with @BowmanJacob_ , Chris Wilson, and @graham_raby
How much does upper thermal tolerance vary among wild populations of brook trout? What drives this variation? 🌡️

Very proud of @wut_a_hoot for the great work put into this study 🥳. It raises some really fascinating questions that we hope will stimulate more research into how social & physiological traits interact to determine growth rate in fish! #fishsci

Excited about sharing our new paper @Timothy_D_Clark @wut_a_hoot – my first paper:
"Hyperoxia disproportionally benefits the aerobic performance of large fish at elevated temperature"

In this new collaborative @J_Exp_Biol commentary, we discuss the differences of maximum oxygen uptake obtained with a swim tunnel or during recovery from an exhaustive chase. 🐟🐠🦈

The OptoReg system: A simple and inexpensive solution for regulating water oxygen using a FireSting-O2
Toolbox paper @conphysjournal

ALT Toolbox paper in @conphysjournal @RasmusErn & @FredrikJutfelt https://doi.org/10.1093/conphys/coae024. This paper describes an optocoupler-based regulation apparatus for saturation manipulation of oxygen in water (OptoReg). This system enables control of solenoid valves for oxygen and nitrogen gases using a FireSting-O2 meter, an optocoupler box, and an electronic switch box. The hardware components connect to a computer through USB cables. The control software is free and has a graphical user interface, making it easy to use. With the OptoReg system, any lab with a computer running Microsoft Windows operating system and a 4-channel FireSting-O2 meter can easily and cheaply set up four independently controlled systems for regulating water oxygen levels. Here we describe how to assemble and run the OptoReg system and present a data set demonstrating the high precision and stability of the OptoReg system during static acclimation experiments and dynamic warming trials.

Its long been assumed that a reduction in the SDA will provide more ‘free’ energy for allocation to animal growth. In our JEB commentary, we are proposing the exact opposite: that a larger SDA might actually be indicative of better growth performance

Two more papers by Dixson and Munday get Editorial Expressions of Concern for raw data issues. These papers have previously been flagged as having unrealistic variance for fish behaviour.

Our new encyclopedia chapter Effects of Climate Warming is out!
It’s a broad review covering acute and chronic effects of warming on fish physiology. I’ll break it down below.

Huge undertaking by @FishSciSkeeles to raise fish for a year with or without supplemental oxygen to see whether it enhanced growth rates & supported the gill-oxygen limitation hypothesis. It didn’t! BUT, a cool finding RE oxygen extending the reproductive window!
For those still on here, I'm super stoked to see this one out there! 🐟🔥🤏 @Timothy_D_Clark @ScheuffeleHanna @DeakinSEBE @deakinresearch
Supplemental oxygen does not improve growth but can enhance reproductive capacity of fish

Incredibly proud of @FishSciSkeeles for submitting his awesome PhD thesis! Lots of hurdles along the way, including arriving in Oz immediately before ~18 months of COVID lockdowns, but he totally smashed it! 🙌🏼💪🏽
Got the PhD submitted today 🐟🙏
Below are photos at day 1 of the journey and today, the final shebang.
Yes yes, you’d hope there’s some real strong correlation between hair growth and knowledge gain here 😂
