    Cooperative species, like humans, can display spontaneously prosocial behaviour. Experiments on a monogamous fish with biparental care shows that pair bonded males are prosocial to both their long-term mates and to strange females, but make antisocial choices if their mate is watching, or if another male is the potential recipient.

    Historical climate adaptation can give insight into the potential for adaptation to contemporary changing climates. Here Bennett et al. investigate thermal tolerance evolution across much of the tree of life and find different effects of ancestral climate on the subsequent evolution of ectotherms vs. endotherms.

    Germ-free mosquitoes generated with current methods exhibit developmental deficits. Here, the authors use genetically modified bacteria to allow complete decolonisation at any developmental stage of Aedes aegypti mosquitoes and show that bacteria support larval development by contributing to folate biosynthesis and enhancing energy storage.

    Connecting genotypes to complex social behaviour is challenging. Taylor et al. use machine learning to show a strong response of caste-associated gene expression to queen loss, wherein individual wasp’s expression profiles become intermediate between queen and worker states, even in the absence of behavioural changes.

    Climate change may pose a challenge not only for survival of animals but also for their reproduction. Here, Schou et al. analyse how male and female ostrich fertility relates to fluctuating temperature across 20 years, finding reduced fertility away from the thermal optimum, but also individual variation in thermal tolerance.

    Shark teeth have short lifespans yet can be subject to significant mechanical damage. Here, the authors report on a site-specific damage mechanism in shark teeth enameloid, which maintains tooth functional shape, providing experimental evidence that tooth architecture may have influenced the diversification of shark ecologies over evolution.

    Pesticides could increase bees’ susceptibility to parasites, but the nature of this interaction has been unclear. Here the authors show that the pesticide Clothianidin reduces the wound healing immune response in bees, allowing the ectoparasitic Varroa mites to consume more bee hemolymph and amplify reproduction.

    Cichlids are a model for adaptive radiation, but the timing of their diversification is debated. Here the authors assemble 14 cichlid genomes, introduce a Bayesian approach to account for fossil-assignment uncertainty, and present a dated phylogenomic hypothesis of cichlid and teleost evolution.

    The pathogen Batrachochytrium dendrobatidis (BD) associated with widespread amphibian declines is present in Europe but has not consistently caused disease-induced declines in that region. Here, the authors suggest that an endemic strain of BD with low virulence may protect the hosts upon co-infection with more virulent strains.

    Whether or not species—when introduced to a new location—eventually become invasive has been linked to the specices’ capacity to expand its niche. However, here the authors show that the extent of niche shift is smaller in non-invasive than invasive ant species, questioning this established hypothesis.

    Modern mammals are endothermic, but it has not been clear when this type of metabolism evolved. Here, Newham et al. analyse tooth and bone structure in Early Jurassic stem-mammal fossils to estimate lifespan and blood flow rates, which inform about basal and maximum metabolic rates, respectively, and show these stem-mammals had metabolic rates closer to modern ectothermic reptiles than to endothermic mammals.

    The social intelligence hypothesis predicts that social organisms tend to be more intelligent because within-group interactions drive cognitive evolution. Here, authors propose that conspecific outsiders can be just as important in selecting for sophisticated cognitive adaptations.

    Song et al. inferred that stridulatory wings and tibial ears co-evolved in a sexual context among crickets, katydids, and their allies, while abdominal ears evolved first in a non-sexual context in grasshoppers, and were later co-opted for courtship. They found little evidence that the evolution of these organs increased lineage diversification.

    Animal signals often encode information on the emitter’s species identity. Using woodpecker drumming as a model, here the authors show that limited signal divergence during a clade radiation does not impair species discrimination, as long as the signals are adapted to local ecological requirements.

    There are gaps in international efforts to monitor the wildlife trade, with many species potentially being undetected by the established monitoring groups. Here the authors use an automated web search to document the sale of reptiles online, revealing over 36% of all known reptile species are in trade, including many missing from official databases.

    Environmental variability is one potential driver of behavioural and cultural diversity in humans and other animals. Here, the authors show that chimpanzee behavioural diversity is higher in habitats that are more seasonal and historically unstable, and in savannah woodland relative to forested sites.

    “Life in a seasonal environment requires appropriate timing of physiological changes to survive, but how the circadian clockwork times these changes remains unclear. Here the authors show that the circadian clock genes BMAL2 and DEC1, in concert with epigenetic pathways in the pituitary, have a central role in seasonal timekeeping in mammals.”

    Little is known about gene expression of organisms in the deep sea, partially owing to constraints on sampling these organisms in situ. Here the authors circumvent this problem, fixing tissue of a deep-sea mussel at 1,688 m in depth, and later analyzing transcriptomes to reveal gene expression patterns showing tidal oscillations.

    In animal groups, the degree of alignment of individuals could have different benefits and costs for individuals depending on their reliance on private or social information. Here the authors show that in shoals of three-spined sticklebacks, some individuals reach resources faster when groups are disordered, a state which favours reliance on privately acquired information, while other individuals reach resources faster when groups are ordered, allowing them to exploit social information more effectively.

    Fast metabolisms tend to shorten lifespans by increasing oxidative damage. This study identifies a gene mutation that keeps a key antioxidant response active, possibly allowing Neoaves bird species to avoid the tradeoff between rapid metabolism and longevity that challenges most mammals, including humans.

    Sea-ice cover in Antarctica has increased over the last decades and reached a maximum in 2014. Here, the authors report strong declines in zoobenthic biomass and abundance and changes in community composition on the NE Weddell Sea shelf over 26 years, with implications for blue carbon and biochemistry in a globally important marine region.

    Chronic bee paralysis is a viral disease of honey bees with a global distribution, but its epidemiology isn’t well understood. Here, Budge et al., using government honey bee health inspection records from England and Wales, demonstrate the disease is emergent and highlight periodic reintroduction of the disease between years.

    Organisms living on and inside of plants—such as microbes and herbivorous insects—can interact in complex ways. Here the authors show that a plant virus increases the temperature of the plant and also the thermal tolerance of an aphid species feeding on the plant; this change in thermal tolerance also affects competition with another aphid species.

    Zoos contribute to conservation actions in the wild. Here, Mooney et al. use a global dataset to show that, while zoos with more and larger animals attract the most visitors and contribute the most to conservation projects, there are viable alternative strategies to maximise attendance and conservation activity.
