Group Size Dependent Selection for Cooperation Versus Freeloading in Collective Chemical Defence
Theory predicts that cooperation in public goods should be favoured in smaller groups because individuals gain a larger share of the benefits, but empirical evidence remains scarce outside microbial systems. Using collectively defending larvae of the pine sawfly Neodiprion sertifer, we show that survival benefits of cooperation are stronger in small ...

ABSTRACT Exposure to environmental pollutants can disrupt the gut microbiota, but how pollutants impact natural, seasonal changes in wildlife gut microbiota remains unknown. We quantified how exposure to radionuclides affected temporal changes in the gut microbiota of bank voles (Clethrionomys glareolus) inhabiting the Chornobyl Exclusion Zone (CEZ ...

Skin Colour in Salamanders Is Modulated by Both Epitranscriptomic Methylation and Gene Expression
ABSTRACT Animal colouration is a key trait in organismal biology, being involved in natural and sexual selection, competition, and communication. Amphibians use their highly diverse colouration in many ecological interactions, but the molecular bases of their colour variation are less well understood than in other vertebrate systems. While the genetic,

We investigate the effect of previous mating opportunities with con‐ and heterospecifics on the subsequent mating decisions of male Lygaeus simulans seed bugs. We found that males were less likely to copulate with both con‐ and heterospecific females if they had previously encountered a heterospecific female, and more likely to copulate with ...

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.

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.

1922 is typically read as the defining year of literary modernism: the year of The Waste Land, Ulysses, and Jacob’s Room. But what else was published that year? And how can we understand the field of literary production in 1922 as extending beyond those canonical modernist monuments?

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