That moment when you resolve the final comment on a manuscript and the whole document snaps back to the centre of the screen. Peak academic satisfaction, possibly better than publication.

Our new study: territorial cichlids ramped up metabolic rate around conspecifics, while cardinal tetras showed little change. And only in tetras did individual sociability relate to metabolic rate. Energetic consequences of “social living” depend on social system. link.springer.com/article/10.1...

Ecstatic about the Blue Jays knocking off the Yankees🥳. Less ecstatic about what this will continue to do to my sleep schedule watching games from Scotland😭.

Fisheries can drive selection, but what about small-scale ornamental fisheries? Our new study shows Amazonian fishes interact w/ traps in species- & environment-specific ways, hinting at overlooked selective potential. Led by @marpineda.bsky.social Read here: onlinelibrary.wiley.com/doi/epdf/10....

Our new paper shows how arena size can bias sociability estimates in sticklebacks: bigger tanks = lower sociability, even after adjusting for tank size. Repeatability highest at intermediate size. #methodsmatter! Great work from @mgmci13.bsky.social! Read it here: link.springer.com/article/10.1...

🧵THREAD: (1/7) Standard metabolic rate (SMR) is one of biology's most measured traits. We argue it isn't the constant baseline it's assumed to be. Our preprint discusses how sleep-wake cycles create a 'metabolic mosaic' that requires us to rethink how we interpret SMR. ecoevorxiv.org/repository/v...

In our new correspondence, we discuss how light-based methods of sleep disruption may generate confounds that complicate interpretation of results. Light affects hormones, circadian rhythms & stress responses beyond just sleep! @helenanorman.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

After so many years of toil, we've finally done it. Definitive proof that guppies can quantum phase shift between dimensions. Congrats to @helenanorman.bsky.social for this game-changing discovery. 🥳 #fishsci

Outstanding talk by @helenanorman.bsky.social for @pintofscience.uk on the nature of sleep in fish and other animals. Incredible that we know so little about this vitally important process. More to come from this fantastic scientist!

Kayaked around the gorgeous Loch Drunkie, apparently named after the time whisky smugglers rolled their cargo into the water to dodge tax men. Today, no whisky, no rain, no midges. Just a creeping feeling that Scotland is becoming Portugal. Has barely rained here since March 😮 .

Attenborough voice: Between the Isles of Tiree and Coll, a lone human paddles through turquoise water. Three seals follow. Watching. Studying. But mostly mocking the paddling ability. The human lurches on toward pristine sands, dignity mostly intact.

Great day for a run! 11th year in a row coming back to the magical Isle of #Tiree for their annual half marathon 😊. Always amazing scenery, community, and hospitality. Now for a few more days of chilling on this incredible wee island.
