Data from: Alien and native plant establishment in grassland communities is more strongly affected by disturbance than above- and below-ground enemies

Gregor Müller, Lena Horstmeyer, Tilman Rönneburg, Mark Van Kleunen & Wayne Dawson
Understanding the factors that drive commonness and rarity of plant species and whether these factors differ for alien and native species are key questions in ecology. If a species is to become common in a community, incoming propagules must first be able to establish. The latter could be determined by competition with resident plants, the impacts of herbivores and soil biota, or a combination of these factors. We aimed to tease apart the roles that...

Data from: Effects of pollination intensity on offspring number and quality in a wind-pollinated herb

Anne-Marie Labouche, Shane A. Richards & John R. Pannell
Low pollination intensity may cause low seed set in plant populations and is thought to be responsible for evolutionary transitions from outcrossing to selfing, or from animal to wind pollination. Variation in pollination intensity may also affect seed quality both through its influence on the degree of pollen competition (with lower quality offspring produced under low pollen intensities) and through seed size–number trade-offs (with plants under low pollination intensity producing fewer but larger seeds). Here,...

Data from: Population differentiation in the context of Holocene climate change for a migratory marine species, the southern elephant seal

Laura J. Corrigan, Anna Fabiani, Lucas F. Chauke, Clive R. McMahon, Mark De Bruyn, Marthan N. Bester, Amanda Bastos, Claudio Campagna, Monica M.C. Muelbert & A. Rus Hoelzel
Understanding observed patterns of connectivity requires an understanding of the evolutionary processes that determine genetic structure among populations, with the most common models being associated with isolation by distance, allopatry or vicariance. Pinnipeds are annual breeders with the capacity for extensive range overlap during seasonal migrations, establishing the potential for the evolution of isolation by distance. Here we assess the pattern of differentiation among six breeding colonies of the southern elephant seal, Mirounga leonina, based...

Data from: Commonness and rarity of alien and native plant species – the relative roles of intraspecific competition and plant–soil feedback

Gregor Müller, Mark Van Kleunen & Wayne Dawson
The success of invasive alien and common native species may be explained by the same underlying mechanisms. Differences in intraspecific competition as well as differences in plant–soil feedback have been put forward as potential determinants of plant success. We teased apart the relative roles of competition and plant–soil feedback in a greenhouse experiment with 30 common and rare alien and native species from nine plant families. We tested whether plant biomass decreased less for common...

Data from: Allometric scaling of intraspecific space use

Carolyn M. Rosten, Rodolphe E. Gozlan & Martyn C. Lucas
Allometric scaling relationships enable exploration of animal space-use patterns, yet interspecific studies cannot address many of the underlying mechanisms. We present the first intraspecific study of home range (HR) allometry relative to energetic requirements over several orders of magnitude of body mass, using as a model the predatory fish, pike Esox lucius. Analogous with interspecific studies, we show that space use increases more rapidly with mass (exponent = 1.08) than metabolic scaling theories predict. Our...

Data from: Mate-guarding by male mandrills (Mandrillus sphinx) is associated with female MHC genotype

Joanna M. Setchell, Shane A. Richards, Kristin M. Abbott & Leslie A. Knapp
Female choice for male major histocompatibility complex (MHC) genotype has been widely tested, but the relationship between male mating strategies and female MHC genotype has received far less attention. Moreover, few studies of MHC-associated mate choice test for the fitness effects underlying such choice. We examined mate-guarding by male mandrills, a species with intense male–male competition and female offspring care. We developed a statistical model based on 10 years of observations to describe how the...

Data from: Rhenium uptake and distribution in phaeophyceae macroalgae, Fucus vesiculosus

Blanca Racionero-Gómez, Adam D. Sproson, Dave Selby, Darren R. Gröcke, Hilary Redden & H. Christopher Greenwell
Owing to Rhenium (Re) having no known biological role, it is not fully understood how Re is concentrated in oil kerogens. A commonly held assumption is that Re is incorporated into decomposing biomass under reducing conditions. However, living macroalgae also concentrate Re to several orders of magnitude greater than that of seawater. This study uses Fucus vesiculosus to assess Re uptake and its subsequent localization in the biomass. It is demonstrated that the Re abundance...

Data from: Cats, connectivity and conservation: incorporating datasets and integrating scales for wildlife management

Ross T. Pitman, Julien Fattebert, Samual T. Williams, Kathryn S. Williams, Russell A. Hill, Luke T. B. Hunter, Hugh Robinson, John Power, Lourens Swanepoel, Rob Slotow & Guy A. Balme
Understanding resource selection and quantifying habitat connectivity are fundamental to conservation planning for both land-use and species management plans. However, datasets available to management authorities for resource selection and connectivity analyses are often highly limited and fragmentary. As a result, measuring connectivity is challenging, and often poorly integrated within conservation planning and wildlife management. To exacerbate the challenge, scale-dependent resource use makes inference across scales problematic, resource use is often modelled in areas where the...

Data from: Introgression and selection shaped the evolutionary history of sympatric sister-species of coral reef fishes (genus: Haemulon)

Moises A. Bernal, Michelle R. Gaither, Warren Brian Simison & Luiz A. Rocha
Closely related marine species with large sympatric ranges provide opportunities to study the mechanisms of speciation, particularly when there is evidence of gene flow between the lineages. Here we focus on a case of hybridization between the sympatric sister-species Haemulon maculicauda and H. flaviguttatum, using Sanger sequencing of mitochondrial and nuclear loci, as well as 2422 single nucleotide polymorphisms (SNPs) obtained via Restriction-site Associated DNA Sequencing (RADSeq). Mitochondrial markers revealed a shared haplotype for COI...

Data from: Post-glacial habitat release and incipient speciation in the genus Delphinus

Iris Segura-García, Juan Pablo Gallo, Susan Chivers, Raúl Díaz-Gamboa & A. Rus Hoelzel
The role of ecological and changing environmental factors in the radiation of species diversity is a fundamental question in evolutionary biology. Of particular interest is the potential for these factors to determine the boundary between what we would consider differentiation among populations and incipient speciation. Dolphins in the genus Delphinus provide a useful test case, exhibiting morphological variation in beak length, coloration and body size across their wide geographic distribution, and in particular among coastal...

Data from: Biogeographic and bathymetric determinants of brachiopod extinction and survival during the Late Ordovician Mass Extinction

Seth Finnegan, David Harper, Christian Rasmussen & David A. T. Harper
The Late Ordovician Mass Extinction (LOME) coincided with dramatic climate changes, but there are numerous ways in which these changes could have driven marine extinctions. We use a palaeobiogeographic database of rhynchonelliform brachiopods to examine the selectivity of Late Ordovician – Early Silurian genus extinctions and evaluate which extinction drivers are best supported by the data. The first (latest Katian) pulse of the LOME preferentially affected genera restricted to deeper waters or to relatively narrow...

Data from: Onychophoran-like musculature in a phosphatized Cambrian lobopodian

Xi-Guang Zhang, Martin Smith, Jie Yang, Jin-Bo Hou & Martin R. Smith
The restricted, exclusively terrestrial distribution of modern Onychophora contrasts strikingly with the rich diversity of onychophoran-like fossils preserved in marine Cambrian Lagerstätten. The transition from these early forebears to the modern onychophoran body plan is poorly constrained, in part due to the absence of fossils preserving details of the soft anatomy. Here we report muscle tissue in a new early Cambrian (Stage 3) lobopodian, Tritonychus phanerosarkus gen. et sp. nov., preserved in the Orsten fashion...
