The Coevolution of Colour Patterns and Hindwing Shapes on a Large Phylogenetic Scale Reveals Predation‐Driven Adaptive Syndromes in Swallowtail Butterflies

open access: yesEcology Letters, Volume 29, Issue 1, January 2026.
By combining computer vision and morphometrics on museum specimens, we show that hindwing tail shape and colour patterns evolved in concert across swallowtails. Long‐tailed species display contrasted stripes and marginal spots, suggesting coevolution of deflective traits promoted by natural selection by predators.

Pigments, Chromatophore Structure, and Gene Expression Underlying Colour Polytypy of a Panamanian Poison Frog

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Colour polytypism represents an example of phenotypic diversification shaped by genetic divergence and ecological pressures. Poison frogs of the genus Oophaga (Dendrobatidae) are highly polytypic in coloration, making them an ideal system for investigating the genetic and physiological basis of colour variation.

Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
The foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic. In this study, we ensure predators

Predictors of Wing Attacks by Birds Across Australian Butterflies

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Predation pressure can vary latitudinally and across different prey communities as well as between males and females of the same prey species. Here, the variation in predation pressure on Australian butterflies was assessed using wing damage caused by bird attacks in over 2310 individuals from five butterfly families.
