Data from: The socially mediated recovery of a fearful fish paired with periodically replaced calm modelsAdam L. Crane, Kevin R. Bairos-Novak, Laurel H. Sacco, Maud C.O. Ferrari & Maud C. O. Ferrari
Social learning is an important mechanism for acquiring knowledge about environmental risk. However, little work has explored the learning of safety and how such learning outcomes are shaped by the social environment. Here, we exposed minnows, Pimephales promelas, to a high-risk environment to induce behavioral responses associated with fear (e.g., neophobia). We then used the presence of calm conspecific models (low-risk individuals) to weaken these responses. When observers (individuals from the high-risk environment) and models...
Data from: Phylogenetic diversity patterns in Himalayan forests reveal evidence for environmental filtering of distinct lineagesStephanie Shooner, T. Jonathan Davies, Purabi Saikia, Jyotishman Deka, Sanjeeb Bharali, Om Prakash Tripathi, Lalbihari Singha, Mohammed Latif Khan & Selvadurai Dayanandan
Large‐scale environmental gradients have been invaluable for unraveling the processes shaping the evolution and maintenance of biodiversity. Environmental gradients provide a natural setting to test theories about species diversity and distributions within a landscape with changing biotic and abiotic interactions. Elevational gradients are particularly useful because they often encompass a large climatic range within a small geographical extent. Here, we analyzed tree communities in plots located throughout Arunachal Pradesh, a province in northeast India located...
Data from: Data management, archiving and sharing for biologists and the role of research institutions in the technology-oriented ageSebastien Renaut, Amber E. Budden, Dominique Gravel, Timothée Poisot & Pedro Peres-Neto
Data are one of the primary outputs of science. Although certain sub-disciplines of biology have pioneered efforts to ensure their long-term preservation and facilitate collaborations, data continue to disappear, owing mostly to technological, regulatory and ideological hurdles. In this review, we describe the important steps towards proper data management and archiving, and provide a critical discussion on the importance of long term data conservation. We then illustrate the rise in data archiving through the Joint...
Data from: Systematic deviations from linear size spectra of lake fish communities are correlated with predator-prey interactions and lake-use intensityIgnasi Arranz, Chih-Hao Hsieh, Thomas Mehner & Sandra Brucet
Size structure of organisms at logarithmic scale (i.e. size spectrum) can often be described by a linear function with a negative slope; however, substantial deviations from linearity have often been found in natural systems. Theoretical studies suggest that greater nonlinearity in community size spectrum is associated with high predator-prey size ratios but low predator-prey abundance ratios; however, empirical evaluation of the effects of predator-prey interactions on nonlinear structures remains scarce. Here, we aim to empirically...
Data from: Assessing among-lineage variability in phylogenetic imputation of functional trait datasetsRafael Molin-Venegas, Juan Carlos Moreno-Saiz, Isabel Castro Castro, T. Jonathan Davies, Pedro R. Peres-Neto, Miguel Á. Rodriguez & Rafael Molina-Venegas
Phylogenetic imputation has recently emerged as a potentially powerful tool for predicting missing data in functional traits datasets. As such, understanding the limitations of phylogenetic modelling in predicting trait values is critical if we are to use them in subsequent analyses. Previous studies have focused on the relationship between phylogenetic signal and clade-level prediction accuracy, yet variability in prediction accuracy among individual tips of phylogenies remains largely unexplored. Here, we used simulations of trait evolution...
Understanding the extent to which captivity generates maladaptation in wild species can inform species recovery programs and elucidate wild population responses to novel environmental change. Though rarely quantified, effective population size (Ne) and genetic diversity should influence the magnitude of plastic and genetic changes manifested in captivity that reduce wild fitness. Sexually-dimorphic traits might also mediate consequences of captivity. To evaluate these relationships, we generated >600 full- and half-sibling families from nine wild brook trout...
