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

(2/7) Different maintenance processes occur at different times. Ion regulation & thermoregulation are active during wake. Protein synth, many brain functions, immunity peak during sleep. How “maintenance” is defined and what constitutes SMR depends entirely on WHEN you measure it

New paper led by @daphnecortese & @ScienceMunster, links btwn cognition and metabolism vary with maze complexity, prob due to differences in exploration or memory. Context effects of maze design are key to consider in cognition studies! sciencedirect.com/science/ar…

New systematic review and meta-analysis, led by @ITiddy, on how climate stressors affect fish social behaviour. Inconsistent effects of temperature & CO2; hypoxia can decrease social cohesion. Overall, much more data needed for fully understanding effects. onlinelibrary.wiley.com/doi/…

Sleep occurs across animals, yet we know almost nothing about interactions among sleep, ecology, and environmental change. Our new systematic review led by Helena Norman reviews sleep in fish and avenues for future research in this fascinating field: journals.biologists.com/jeb/…

Doing meta-analysis w/ colleagues. We noticed large differences in papers found when doing same search with @Clarivate Web of Science. Search returns vary depending on institution subscriptions. I suspect many aren't aware of this. Defeats the purpose of standardized searches!

Specifically, using the exact same search string, my Web of Science search returned 2,302 abstracts, whereas theirs returned only 1,755. A pretty shocking difference!

~2 years ago, we caught this Amazonian pleco in the River Kelvin, Glasgow, while netting minnows. There were two others in the same area, probably released from a home aquarium. Read about it here and the invasive potential of these fish in our new paper: reabic.net/journals/bir/2024…

Excited to announce that applications are open for the 2nd edition of our workshop on vertebrate anatomy and ecophysiogy! Come gain hands-on experience in dissecting across the tree of life. Workshop in Glasgow on April 12, see below for more info! @KRuthsatz @zoology_museum

Any marine snail experts, particularly with Drupella, we need your help please! Do these white bumps along the shell opening identify species or sexes? A student observed both types (with and without bumps) within the same aggregation. @SuzanneCMills

Here are more examples. Within each type (bumps vs no bumps), there is variation in other shell characteristics.

People have studied effects of capture/discard in commercial and recreational fisheries, but what about the ornamental fish trade? Our paper in @conphysjournal looks at metabolic recovery after capture & discard in Amazonian dwarf cichlids. (1/3) (academic.oup.com/conphys/art…

We find that while most individuals recovery from capture quickly, increased air-exposure prolongs recovery after release. Males also seem to take longer to recover, with a reduced aerobic scope in the few hours after release. (2/3)

It is often assumed that correlations btwn metabolic rate and behaviour can cause indirect selection. By examining numerous behaviours, our paper by @AmelieCrespel shows when this "phenotypic gambit" is incorrect & why genetic correlations are needed: royalsocietypublishing.org/d…

Fantastic new analysis by @levet_marie showing non-linear, dose-dependent effects of immune system stimulation on metabolism and gene expression in a damselfish species. This was a very complex dataset and an amazing effort pulling it all together. cdnsciencepub.com/doi/10.113…

This week is #FishInResearch week! Fish are the most diverse vertebrates with more species than mammals, birds, reptiles, and amphibians combined. This week I'll highlight how they've been critical in extending knowledge of ecology, starting with our study of climate change.(1/7)

Fish live in every aquatic habitat on earth & are vital as both predators and prey. This allows us to compare effects of climate change in the tropics, temperate zones, and polar regions. As ectotherms, they are sensitive to temperature change, with broad ecological effects.(2/7)

New @STOTEN_journal: great work by Quentin Queiros to pull apart prey size, feeding, digestion, & temp as sources of reduced size with warming in pelagic fish. Swimming while filter feeding on small prey incurs sig energetic costs. @afishyonado #fishsci sciencedirect.com/science/ar…
