Data from: Fast and cost-effective genetic mapping in apple using next-generation sequencing

Kyle M. Gardner, Thomas F. Cooke, Patrick J. Brown, Scott Cann, Fabrizio Costa, Carlos D. Bustamante, Riccardo Velasco, Michela Troggio, Sean Myles, P. Brown & C. Bustamante
Next-generation DNA sequencing (NGS) produces vast amounts of DNA sequence data, but it is not specifically designed to generate data suitable for genetic mapping. Recently developed DNA library preparation methods for NGS have helped solve this problem, however, by combining the use of reduced representation libraries with DNA sample barcoding to generate genome-wide genotype data from a common set of genetic markers across a large number of samples. Here we use such a method, called...

Data from: Long-term nitrogen addition causes the evolution of less cooperative mutualists

Dylan Jones Weese, Katy D. Heath, Bryn T. M. Dentinger & Jennifer Ann Lau
Human activities have altered the global nitrogen (N) cycle, and as a result, elevated N inputs are causing profound ecological changes in diverse ecosystems. The evolutionary consequences of this global change have been largely ignored even though elevated N inputs are predicted to cause mutualism breakdown and the evolution of decreased cooperation between resource mutualists. Using a long-term (22 year) N addition experiment, we find that elevated N inputs have altered the legume-rhizobium mutualism (where...

Data from: Blinded by the load: attention, awareness and the role of perceptual load

Nilli Lavie, Diane M. Beck & Nikos Konstantinou
What is the relationship between attention and conscious awareness? Awareness sometimes appears to be restricted to the contents of focused attention, yet at other times irrelevant distractors will dominate awareness. This contradictory relationship has also been reflected in an abundance of discrepant research findings leading to an enduring controversy in cognitive psychology. Lavie's load theory of attention suggests that the puzzle can be solved by considering the role of perceptual load. Although distractors will intrude...

Data from: Variability in potential to exploit different soil organic phosphorus compounds among tropical montane tree species

Brian S. Steidinger, Benjamin L. Turner, Adriana Osorio, James W. Dalling & Adriana Corrales
We hypothesized that tropical plant species with different mycorrhizal associations reduce competition for soil phosphorus (P) by specializing to exploit different soil organic P compounds. We assayed the activity of root/mycorrhizal phosphatase enzymes of four tree species with contrasting root symbiotic relationships–arbuscular mycorrhizal (angiosperm and conifer), ectomycorrhizal and non-mycorrhizal–collected from one of three soil sites within a montane tropical forest. We also measured growth and foliar P of these seedlings in an experiment with P...

Data from: Folding wings like a cockroach: a review of transverse wing folding ensign wasps (Hymenoptera: Evaniidae: Afrevania and Trissevania)

István Mikó, Robert S. Copeland, James P. Balhoff, Matthew J. Yoder & Andrew R. Deans
We revise two relatively rare ensign wasp genera, whose species are restricted to Sub-Saharan Africa: Afrevania and Trissevania. Afrevania longipetiolata sp. nov., Trissevania heatherae sp. nov., T. hugoi sp. nov., T. mrimaensis sp. nov. and T. slideri sp. nov. are described, males and females of T. anemotis and Afrevania leroyi are redescribed, and an identification key for Trissevaniini is provided. We argue that Trissevania mrimaensis sp. nov. and T. heatherae sp. nov. populations are vulnerable,...

Data from: Host social behavior decreases exposure to vector-borne disease: a field experiment in a “hotspot” of West Nile virus transmission

Bethany L. Krebs, Tavis K. Anderson, Tony L. Goldberg, Gabriel L. Hamer, Uriel D. Kitron, Christina M. Newman, Marilyn O. Ruiz, Edward D. Walker & J. D. Brawn
Animals can decrease their individual risk of predation by forming groups. The encounter-dilution hypothesis extends the potential benefits of gregariousness to biting insects and vector-borne disease by predicting that the per capita number of insect bites should decrease within larger host groups. Although vector-borne diseases are common and can exert strong selective pressures on hosts, there have been few tests of the encounter-dilution effect in natural systems. We conducted an experimental test of the encounter-dilution...

Data from: Insight into genomic changes accompanying divergence: genetic linkage maps and synteny of Lucania goodei and L. parva reveal a Robertsonian fusion

Emma L. Berdan, Genevieve M. Kozak, Ray Ming, A. Lane Rayburn, Ryan Kiehart & Rebecca C. Fuller
Linkage maps are important tools in evolutionary genetics and in studies of speciation. We performed a karyotyping study and constructed high-density linkage maps for two closely related killifish species, Lucania parva and Lucania goodei, that differ in salinity tolerance and still hybridize in their contact zone in Florida. Using SNPs from orthologous EST contigs, we compared synteny between the two species to determine how genomic architecture has shifted with divergence. Karyotyping revealed that L. goodei...

Data from: No apparent benefits of allonursing for recipient offspring and mothers in the cooperatively breeding meerkat

Kirsty J. MacLeod, Katie E. McGhee & Tim H. Clutton-Brock
1. Cooperative behaviours by definition are those that provide some benefit to another individual. Allonursing, the nursing of non-descendent young, is often considered a cooperative behaviour and is assumed to provide benefits to recipient offspring in terms of growth and survival, and to their mothers, by enabling them to share the lactation load. However, these proposed benefits are not well understood, in part because maternal and litter traits and other ecological and social variables are...

Data from: No clear effect of admixture between two European invading outbreaks of Diabrotica virgifera virgifera in natura

Gérald Bermond, Fanny Cavigliasso, Sophie Mallez, Joseph Spencer & Thomas Guillemaud
In this study, we challenged the hypothesis that admixture may have had a positive impact in the context of the European invasion of the western corn rootworm (WCR), Diabrotica virgifera virgifera, LeConte. This beetle was introduced in Europe from the USA several times since the 1980’s. The multiple introductions of this major pest of cultivated corn led to the formation of two major outbreaks in North Western (NW) Italy and in Central and South Eastern...

Data from: Paternal care in a fish: epigenetics and fitness enhancing effects on offspring anxiety

Katie E. McGhee & Alison M. Bell
In many animals, including humans, interactions with caring parents can have long-lasting effects on offspring sensitivity to stressors. However, whether these parental effects impact offspring fitness in nature is often unclear. In addition, despite evidence that maternal care can influence offspring behaviour via epigenetic alterations to the genome, it remains unclear whether paternal care has similar effects. Here, we show in three-spined sticklebacks, a fish in which fathers are the sole provider of offspring care,...
