Data from: Delimiting species in the genus Otospermophilus (Rodentia: Sciuridae) using genetics, ecology, and morphology

Mark A. Phuong, Marisa C. W. Lim, Daniel R. Wait, Kevin C. Rowe & Craig Moritz
We apply an integrative taxonomy approach to delimit species of ground squirrels in the genus Otospermophilus because the diverse evolutionary histories of organisms shape the existence of taxonomic characters. Previous studies of mitochondrial DNA from this group recovered three divergent lineages within Otospermophilus beecheyi separated into northern, central, and southern geographical populations, with Otospermophilus atricapillus nested within the southern lineage of O. beecheyi. To further evaluate species boundaries within this complex, we collected additional genetic...

Data from: Social effects on foraging behaviour and success depend on local environmental conditions

Harry H. Marshall, Alecia J. Carter, Alexandra Ashford, J. Marcus Rowcliffe & Guy Cowlishaw
In social groups, individuals' dominance rank, social bonds, and kinship with other group members have been shown to influence their foraging behavior. However, there is growing evidence that the particular effects of these social traits may also depend on local environmental conditions. We investigated this by comparing the foraging behavior of wild chacma baboons, Papio ursinus, under natural conditions and in a field experiment where food was spatially clumped. Data were collected from 55 animals...

Data from: Sequence Capture using PCR-generated Probes (SCPP): a cost-effective method of targeted high-throughput sequencing for non-model organisms

Joshua V. Peñalba, Lydia L. Smith, Maria A. Tonione, Chodon Sass, Sarah M. Hykin, Phillip L. Skipwith, James A. McGuire, Rauri C. K. Bowie, Craig Moritz & Jimmy A. McGuire
Recent advances in high-throughput sequencing library preparation and subgenomic enrichment methods have opened new avenues for population genetics and phylogenetics of non-model organisms. To multiplex large numbers of indexed samples while sequencing predominantly orthologous, targeted regions of the genome, we propose modifications to an existing, in-solution capture that utilizes PCR products as target probes to enrich library pools for the genomic subset of interest. The sequence capture using PCR-generated probes (SCPP) protocol requires no specialized...

Data from: Robustness of habitat-based surrogates of animal diversity: a multi-taxa comparison over time

Philip S. Barton, Martin J. Westgate, Peter W. Lane, Christopher MacGregor & David B. Lindenmayer
Many animal taxa respond strongly to spatial and temporal variation in vegetation structure and floristic composition, suggesting that changes in vegetation could be a cheap and readily observable surrogate for changes in animal assemblages. Yet there is considerable uncertainty about how different taxa respond to vegetation over time, potentially limiting the application of habitat-based surrogates to many areas of applied ecology. We examined the strength and temporal consistency of habitat-based surrogates of three different vertebrate...

Data from: Signal design and courtship presentation coincide for highly biased delivery of an iridescent butterfly mating signal

Thomas Edward White, Jochen Zeil & Darrell J. Kemp
Sensory drive theory contends that signalling systems should evolve to optimize transmission between senders and intended receivers, while minimising visibility to eavesdroppers where possible. In visual communication systems, the high directionality afforded by iridescent colouration presents underappreciated avenues for mediating this trade-off. This hypothesis predicts functional links between signal design and presentation such that visual conspicuousness is maximised only under ecologically relevant settings and/or to select audiences. We addressed this prediction using Hypolimnas bolina, a...

Data from: Tree imbalance causes a bias in phylogenetic estimation of evolutionary timescales using heterochronous sequences

David Duchêne, Sebastián Duchêne & Simon Y. W. Ho
Phylogenetic estimation of evolutionary timescales has become routine in biology, forming the basis of a wide range of evolutionary and ecological studies. However, there are various sources of bias that can affect these estimates. We investigated whether tree imbalance, a property that is commonly observed in phylogenetic trees, can lead to reduced accuracy or precision of phylogenetic timescale estimates. We analysed simulated data sets with calibrations at internal nodes and at the tips, taking into...
