Data from: Estimating speciation and extinction rates for phylogenies of higher taxa

Tanja Stadler & Folmer Bokma
Speciation and extinction rates can be estimated from molecular phylogenies. Recently, a number of methods have been published showing that these rates can be estimated even if the phylogeny is incomplete, that is, if not all extant species are included. We show that the accuracy of such methods strongly depends on making the correct assumptions about how the sampling process was performed. We focus on phylogenies that are incomplete because some subclades (e.g., genera and...

On the occasion of the release of v4.4 of the DataCite Metadata Schema its Metadata Working Group has updated the mapping to Dublin Core. This replaces the mapping in the Appendix of the DataCite-MetadataKernel v2.1. The mapping can be used to convert records described following version 4.4 of the DataCite Metadata Schema into records that comply with the Dublin Core Metadata Initiative Schema.

Diffusion-mediated HEI10 coarsening can explain meiotic crossover positioning in Arabidopsis

Christopher Morgan
In most organisms, the number and distribution of crossovers that occur during meiosis are tightly controlled. All chromosomes must receive at least one “obligatory crossover” and crossovers are prevented from occurring near one another by “crossover interference”. However, the mechanistic basis of this phenomenon of crossover interference has remained mostly mysterious. Using quantitative super-resolution cytogenetics and mathematical modelling, we investigated crossover positioning in the Arabidopsis thaliana wild-type, an over-expressor of the conserved E3 ligase HEI10,...

Data from: Population genetic dynamics of an invasion reconstructed from the sediment egg bank

Markus Möst, Sarah Oexle, Silvia Markova, Dalia Aidukaite, Livia Baumgartner, Hans-Bernd Stich, Martin Wessels, Dominik Martin-Creuzburg & Piet Spaak
Biological invasions are a global issue with far-reaching consequences for single species, communities and whole ecosystems. Our understanding of modes and mechanisms of biological invasions requires knowledge of the genetic processes associated with successful invasions. In many instances, this information is particularly difficult to obtain as the initial phases of the invasion process often pass unnoticed and we rely on inferences from contemporary population genetic data. Here, we combined historic information with the genetic analysis...

Data from: No carbon \"bet hedging\" in pine seedlings under prolonged summer drought and elevated CO2

Christoph Bachofen, Barbara Moser, Günter Hoch, Jaboury Ghazoul, Tom Wohlgemuth & Thomas Wohlgemuth
More frequent drought episodes are expected to cause higher mortality in isohydric tree species such as pines, because individuals close their stomata early during drought in order to maintain constant needle water potentials. It has been suggested that trees delay the ensuing carbon starvation by actively storing carbon at the expense of growth (“bet hedging”). Because such a strategy is only adaptive in drought-prone regions, we hypothesise that the degree of carbon “bet hedging” should...

Data from: No association between sperm competition and sperm length variation across dung flies (Scathophagidae)

Manmohan D. Sharma, Aria M. Minder & David J. Hosken
Sperm length is extremely variable across species, but a general explanation for this variation is lacking. However, when the risk of sperm competition is high, sperm length is predicted to be less variable within species, and there is some evidence for this in birds and social insects. Here, we examined intraspecific variation in sperm length, both within and between males, and its potential associations with sperm competition risk and variation in female reproductive tract morphology...

Data from: Tracing coco de mer’s reproductive history: pollen and nutrient limitation reduce fecundity

Emma J. Morgan, Christopher N. Kaiser-Bunbury, Peter J. Edwards, Frauke Fleischer-Dogley & Christopher J. Kettle
Habitat degradation can reduce or even prevent the reproduction of previously abundant plant species. To develop appropriate management strategies, we need to understand the reasons for reduced recruitment in degraded ecosystems. The dioecious coco de mer palm (Lodoicea maldivica) produces by far the largest seeds of any plant. It is a keystone species in an ancient palm forest that occurs only on two small islands in the Seychelles, yet contemporary rates of seed production are...

Data from: A further cost for the sicker sex? Evidence for male-biased parasite-induced vulnerability to predation

Jessica F. Stephenson, Cormac Kinsella, Joanne Cable & Cock Van Oosterhout
Males are typically the sicker sex. Data from multiple taxa indicate that they are more likely to be infected with parasites, and are less “tolerant,” or less able to mitigate the fitness costs of a given infection, than females. One cost of infection for many animals is an increased probability of being captured by a predator. A clear, hitherto untested, prediction is therefore that this parasite-induced vulnerability to predation is more pronounced among males than...

Data from: Cross-biome patterns in soil microbial respiration predictable from evolutionary theory on thermal adaptation

Mark A. Bradford, Rebecca L. McCulley, Thomas W. Crowther, Emily E. Oldfield, Stephen A. Wood & Noah Fierer
Climate warming may stimulate microbial metabolism of soil carbon, causing a carbon cycle-climate feedback whereby carbon is redistributed from soil to atmospheric CO2. The magnitude of this feedback is uncertain, in part because warming-induced shifts in microbial physiology and/or community composition could retard or accelerate soil carbon losses. Here, we measure microbial respiration rates for soils collected from 22 sites in each of three years, at locations spanning boreal to tropical climates. Respiration was measured...

Data from: Trait means, trait plasticity and trait differences to other species jointly explain species performances in grasslands of varying diversity

Christiane Roscher, Marlén Gubsch, Annett Lipowsky, Jens Schumacher, Alexandra Weigelt, Nina Buchmann, Ernst-Detlef Schulze & Bernhard Schmid
Functional traits may help to explain the great variety of species performances in plant communities, but it is not clear whether the magnitude of trait values of a focal species or trait differences to co-occurring species are key for trait-based predictions. In addition, trait expression within species is often plastic, but this variation has been widely neglected in trait-based analyses. We studied functional traits and plant biomass of 59 species in 66 experimental grassland mixtures...

Data from: Plant spines deter herbivory by restricting caterpillar movement

Rupesh R. Kariyat, Sean B. Hardison, Consuelo M. De Moraes & Mark C. Mescher
The spines of flowering plants are thought to function primarily in defence against mammalian herbivores; however, we previously reported that feeding by Manduca sexta caterpillars on the leaves of horsenettle plants (Solanum carolinense) induces increased development of internode spines on new growth. To determine whether and how spines impact caterpillar feeding, we conducted assays with three Solanaceous plant species that vary in spine numbers (S. carolinense, S. atropurpureum and S. aethiopicum) and also manipulated spine...

Data from: QTL mapping of temperature sensitivity reveals candidate genes for thermal adaptation and growth morphology in the plant pathogenic fungus Zymoseptoria tritici

Mark H. Lendenmann, Daniel Croll, Javier Palma-Guerrero, Ethan L. Stewart & Bruce A. McDonald
Different thermal environments impose strong, differential selection on populations, leading to local adaptation, but the genetic basis of thermal adaptation is poorly understood. We used quantitative trait locus (QTL) mapping in the fungal wheat pathogen Zymoseptoria tritici to study the genetic architecture of thermal adaptation and identify candidate genes. Four wild-type strains originating from the same thermal environment were crossed to generate two mapping populations with 263 (cross 1) and 261 (cross 2) progeny. Restriction...

Data from: The biogeography of kin discrimination across microbial neighbourhoods

Susanne A. Kraemer, Sébastien Wielgoss, Francesca Fiegna & Gregory J. Velicer
The spatial distribution of potential interactants is critical to social evolution in all cooperative organisms. Yet the biogeography of microbial kin discrimination at the scales most relevant to social interactions is poorly understood. Here we resolve the microbiogeography of social identity and genetic relatedness in local populations of the model cooperative bacterium Myxococcus xanthus at small spatial scales, across which the potential for dispersal is high. Using two criteria of relatedness—colony-merger compatibility during cooperative motility...

Data from: Faster clonal turnover in high-infection habitats provides evidence for parasite-mediated selection

Dorota Paczesniak, Sofia Adolfsson, Katri Liljeroos, Kirsten Klappert, Curt M. Lively & Jukka Jokela
According to the Red Queen hypothesis for sex, parasite-mediated selection against common clones counterbalances the reproductive advantage of asexual lineages, which would otherwise outcompete sexual conspecifics. Such selection on the clonal population is expected to lead to a faster clonal turnover in habitats where selection by parasites is stronger. We tested this prediction by comparing the genetic structure of clonal and sexual populations of freshwater snail Potamopyrgus antipodarum between years 2003 and 2007 in three...

Data from: Why there are no essential genes on plasmids

Samuel J. Tazzyman & Sebastian Bonhoeffer
Mobile genetic elements such as plasmids are important for the evolution of prokaryotes. It has been suggested that there are differences between functions coded for by mobile genes and those in the “core” genome and that these differences can be seen between plasmids and chromosomes. In particular, it has been suggested that essential genes, such as those involved in the formation of structural proteins or in basic metabolic functions, are rarely located on plasmids. We...

Data from: A web platform for landuse, climate, demography, hydrology and beach erosion in the Black Sea catchment

Anthony Lehmann, Yaniss Guigoz, Nicolas Ray, Emanuele Mancuso, Karim C. Abbaspour, Elham Rouholahnejad Freund, Karin Allenbach, Andrea De Bono, Marc Fasel, Ana Gago-Silva, Roger Bär, Pierre Lacroix & Grégory Giuliani
The Black Sea catchment (BSC) is facing important demographic, climatic and landuse changes that may increase pollution, vulnerability and scarcity of water resources, as well as beach erosion through sea level rise. Limited access to reliable time-series monitoring data from environmental, statistical, and socio-economical sources is a major barrier to policy development and decision-making. To address these issues, a web-based platform was developed to enable discovery and access to key environmental information for the region....
