Evolution of maturity

Age at maturity in Atlantic salmon is associated with a single locus, vgll3, with sex-specific effects. During sea migration of a large salmon population, rapid evolution towards early maturity is only observed in males.

    Indigenous knowledge and ecological science have complementary differences that can be fruitfully combined to better understand the past and predict the future of social-ecological systems. Cooperation among scientific and Indigenous perspectives can improve conservation and resource management policies.

    Sponges are believed by many researchers to be the earliest living animal group, but there is conflicting evidence for the timing of their origin. A molecular fossil discovery supports the contention that sponges appeared very early, but starkly contradicts the body fossil record.

    Genomic gigantism in amphibians originated through a single extraordinary jump overlying otherwise gradual change; genome size variation is related to both the external environment and life history in frogs, but may not be in salamanders.

    The identification of a set of conserved genes that has had stable expression patterns over 120 million years of ant evolution provides a glimpse into the mechanisms that generate queen and worker castes in ants.

    Priority effects refer to changes in the diversity, composition or function of a community according to the arrival order of species. Here, the authors show that only effects that are compatible with coexistence theory are characterized by positive frequency-dependence.

    How and why individuals of the same species may differ in the way they form pair bonds is not well understood. The authors show that the individual personalities of male great tits (Parus major) regulate how quickly they meet their future partner, and the rate at which they bond with them.

    Microbial mats in extreme environments are analogues of Precambrian ecosystems. Here, the authors analyse metagenomes of microbial mats from a pond along a steep redox gradient and apply a space-for-time approach to infer early Earth metabolic transitions.

    Foliar nitrogen (N) concentrations and isotope ratios obtained from >43,000 samples acquired over 37 years suggest global declines in N supply relative to plant demand, consistent with elevated atmospheric carbon dioxide.

    Adaptive differentiation is poorly understood in marine systems. Here, the authors combine genome sequencing with gene expression and physiology to show that genetic divergence and plasticity contribute to local adaptation of Pacific oyster populations.

    Genomic resources for cartilaginous fishes are scarce. Here, the authors sequence the genome of three sharks and provide insights on the molecular basis of adaptation to underwater lifestyle and the evolutionary origins of vertebrates.

    Female preference is associated with male colour in the Trinidadian guppy. By comparing gene expression patterns in the brains of females with and without preference for colourful males while they evaluate males, the authors identify neurogenomic elements associated with female preference.

    Ant colonies include reproductive queens and sterile workers. Based on brain transcriptomes from five ant species, the authors identify an ancestral gene network for caste differentiation that has been modified over time as ant societies evolved.

    Phylogenetic distribution and phenotypic traits of livestock and crops reveal that domesticated species explore a reduced portion of the phenotypic space occupied by their wild counterparts and have particular traits in common.
