Very exciting to have this out to bridge physiology and physics. #biology #collectivebehaviour #fish #metabolism

Planktivorous reef fishes are thought to possess unique morphological traits to feed on small, evasive prey. Despite the multitude of family-level studies addressing this hypothesis, results remain inconclusive. Our goal, therefore, was to determine whether specialised traits and patterns of morphological convergence are congruent across a comprehensive phylogeny of reef-associated fishes. We measured 15 morphological traits from 815 images of 299 species in 12 globally distributed families. Using phylogenetic comparative methods, we mapped the evolution of plankton-feeding across lineages; assessed the effect of planktivory on body shape; and tested for the presence of morphological convergence among planktivores. We demonstrate that planktivory is evolutionary ubiquitous and occurs in 12 of the most abundant global families. Some morphological trait differences between planktivores and non-planktivores were detected, but there was no difference in overall body shape. Contrary to longstanding assumptions, we show that planktivores have not converged towards distinct morphologies, but instead encompass the entire morphospace of reef fishes. Due to their behavioural, spatial, temporal, and resource heterogeneity, reef fishes of any shape and size can readily navigate the challenges of plankton-feeding.

New paper led by Alexandra McInturf & @physiologyfish.bsky.social
We present a methodological framework for analysing catch data to infer aggregation behaviour. We outline key metrics to explore and apply this framework in a case study of juvenile sharks. ๐Ÿฆˆ

I'm pleased to announce that our paper on the plesiosaur Plesiopterys wildi has been published today in PeerJ: peerj.com/articles/189...
In our study, led by @miguelpmarx.bsky.social, we describe a new and previously undescribed specimen.

๐Ÿ˜ƒ A new article published in J Biomech by Kovรกcs et al suggest sprint runners have longer Achilles tendon moment arms than distance runners in absolute terms, but this does not seem to impact running performance in either group.

Geckos running with dynamic adhesion: towards integration of ecology, energetics and biomechanics Summary: We propose a set of lab and field experiments to further investigate adhesively assisted gecko locomotion, which is controlled by a hierarchical system including muscles, vascular tissue, tendons and hair-like adhesive structures.

Very excited for our new review paper (with Tony Russell) on gecko adhesion, locomotion, and ecomechanics. This stemmed from the JEB symposium last year. @jexpbiol.bsky.social @ucriverside.bsky.social #gecko #ecomechanics #adhesion journals.biologists.com/jeb/article/...
