Data from: Population variation in the life history of a land fish, Alticus arnoldorum, and the effects of predation and density

Edward R. M. Platt & Terry J. Ord
Life history variation can often reflect differences in age-specific mortality within populations, with the general expectation that reproduction should be shifted away from ages experiencing increased mortality. Investigators of life history in vertebrates frequently focus on the impact of predation, but there is increasing evidence that predation may have unexpected impacts on population density that in turn prompt unexpected changes in life history. There are also other reasons why density might impact life history independently...

Data from: Population differentiation and behavioural association of the two ‘personality’ genes DRD4 and SERT in dunnocks (Prunella modularis)

Quantifying the variation in behaviour-related genes within and between populations provides insight into how evolutionary processes shape consistent behavioural traits (i.e. personality). Deliberate introductions of non-native species offer opportunities to investigate how such genes differ between native and introduced populations and how polymorphisms in the genes are related to variation in behaviour. Here, we compared the genetic variation of the two ‘personality’ genes, DRD4 and SERT, between a native (United Kingdom, UK) and an introduced...

Data from: Experimental evidence for phonemic contrasts in a nonhuman vocal system

Sabrina Engesser, Jodie M. S. Crane, James L. Savage, Andrew F. Russell & Simon W. Townsend
The ability to generate new meaning by rearranging combinations of meaningless sounds is a fundamental component of language. Although animal vocalizations often comprise combinations of meaningless acoustic elements, evidence that rearranging such combinations generates functionally distinct meaning is lacking. Here, we provide evidence for this basic ability in calls of the chestnut-crowned babbler (Pomatostomus ruficeps), a highly cooperative bird of the Australian arid zone. Using acoustic analyses, natural observations, and a series of controlled playback...

Data from: From ratites to rats: the size of fleshy fruits shapes species' distributions and continental rainforest assembly

Maurizio Rossetto, Jia-Yee S. Yap, Robert Kooyman & Shawn Laffan
Seed dispersal is a key process in plant spatial dynamics. However, consistently applicable generalisations about dispersal across scales are mostly absent because of the constraints on measuring propagule dispersal distances for many species. Here, we focus on fleshy-fruited taxa, specifically taxa with large fleshy fruits and their dispersers across an entire continental rainforest biome. We compare species-level results of whole-chloroplast DNA analyses in sister taxa with large and small fruits, to regional plot-based samples (310...
