Premise of the study: We sought novel evolutionary insights for the highly diverse Saxifragales by constructing a large phylogenetic tree encompassing 36.8% of the species-level biodiversity. Methods: We built a phylogenetic tree for 909 species of Saxifragales and used this hypothesis to examine character evolution for: annual or perennial habit, woody or herbaceous habit, ovary position, petal number, carpel number, and stamen: petal ratio. We employed likelihood approaches to investigate the effect of habit and...

Data from: Early bursts of body size and shape evolution are rare in comparative data

George Gaylord Simpson famously postulated that much of life's diversity originated as adaptive radiations—more or less simultaneous divergences of numerous lines from a single ancestral adaptive type. However, identifying adaptive radiations has proven difficult due to a lack of broad-scale comparative datasets. Here, we use phylogenetic comparative data on body size and shape in a diversity of animal clades to test a key model of adaptive radiation, in which initially rapid morphological evolution is followed...

Data from: Flower colour and phylogeny along an altitudinal gradient in the Himalaya of Nepal

Mani Shrestha, Adrian Dyer, Prakash Bhattarai, Martin Burd & Adrian G. Dyer
1. Both the phylogenetic structure and trait composition of flowering plant communities may be expected to change with altitude. In particular, floral colours are thought to vary with altitude because Hymenoptera typically decline in importance as pollinators while Diptera and Lepidoptera become more important at higher elevations. Thus, ecological filtering among elevation zones and competitive processes among co-occurring species within zones could influence the floral chromatic cues present at low and high elevations. 2. We...

Data from: Ontogenetic development of intestinal length and relationships to diet in an Australasian fish family (Terapontidae)

Aaron M. Davis, Peter J. Unmack, Bradley J. Pusey, Richard G. Pearson & David L. Morgan
Background: One of the most widely accepted ecomorphological relationships in vertebrates is the negative correlation between intestinal length and proportion of animal prey in diet. While many fish groups exhibit this general pattern, other clades demonstrate minimal, and in some cases contrasting, associations between diet and intestinal length. Moreover, this relationship and its evolutionary derivation have received little attention from a phylogenetic perspective. This study documents the phylogenetic development of intestinal length variability, and resultant...

Data from: Assembly and comparative analysis of transposable elements from low coverage genomic sequence data in Asparagales

Kate L. Hertweck
The research field of comparative genomics is moving from a focus on genes to a more holistic view including the repetitive complement. This study aimed to characterize relative proportions of the repetitive fraction of large, complex genomes in a non-model system. The monocotyledonous plant order Asparagales (onion, asparagus, agave) comprises some of the largest angiosperm genomes and represents variation in both genome size and structure (karyotype). Anonymous, low coverage, single-end Illumina data from eleven exemplar...

Data from: Shades of red: bird-pollinated flowers target the specific colour discrimination abilities of avian vision

Mani Shrestha, Adrian G. Dyer, Skye Boyd-Gerny, Bob B. M. Wong & Martin Burd
Colour signals are a major cue in putative pollination syndromes. There is evidence that the reflectance spectra of many flowers target the distinctive visual discrimination abilities of hymenopteran insects, but far less is known about bird-pollinated flowers. Birds are hypothesized to exert different selective pressures on floral colour compared with hymenopterans because of differences in their visual systems. We measured the floral reflectance spectra of 206 Australian angiosperm species whose floral visitors are known from...

Data from: Are shy individuals less behaviorally variable? Insights from a captive population of mouse lemurs

Jennifer L. Verdolin & John Harper
Increasingly, individual variation in personality has become a focus of behavioral research in animal systems. Boldness and shyness, often quantified as the tendency to explore novel situations, are seen as personality traits important to the fitness landscape of individuals. Here we tested for individual differences within and across contexts in behavioral responses of captive mouse lemurs (Microcebus murinus) to novel objects, novel foods, and handling. We report consistent differences in behavioral responses for objects and...

Data from: Data reuse and the open data citation advantage

Heather A. Piwowar & Todd J. Vision
Background: Attribution to the original contributor upon reuse of published data is important both as a reward for data creators and to document the provenance of research findings. Previous studies have found that papers with publicly available datasets receive a higher number of citations than similar studies without available data. However, few previous analyses have had the statistical power to control for the many variables known to predict citation rate, which has led to uncertain...
