Data from: Power and temptation cause shifts between exploitation and cooperation in a cleaner wrasse mutualism

Simon Gingins, Redouan Bshary, Johanna Werminghausen, Rufus A. Johnstone & Alexandra S. Grutter
In many instances of cooperation, only one individual has both the potential and the incentive to ‘cheat’ and exploit its partner. Under these asymmetric conditions, a simple model predicts that variation in the temptation to cheat and in the potential victim's capacity for partner control leads to shifts between exploitation and cooperation. Here, we show that the threat of early termination of an interaction was sufficient to induce cleaner wrasse Labroides dimidiatus to feed selectively...

Data from: Diplostigmaty in plants: a novel mechanism that provides reproductive assurance

Jonathan Kissling & Spencer C. H. Barrett
Differentiation of female sexual organs in flowering plants is rare, and contrasts with the wide range of male reproductive strategies. An unusual example involves diplostigmaty, the possession of spatially and temporally distinct stigmas in Sebaea (Gentianaceae). Here, the single pistil within a flower has an apical stigma, as occurs in most flowering plants, but also a secondary stigma that occurs mid-way down the style, which is physically discrete and receptive several days after the apical...

Data from: The importance of landscape and spatial structure for hymenopteran-based food webs in an agro-ecosystem

1. Understanding the environmental factors that structure biodiversity and food webs among communities is central to assess and mitigate the impact of landscape changes. 2. Wildflower strips are ecological compensation areas established in farmland to increase pollination services and biological control of crop pests, and to conserve insect diversity. They are arranged in networks in order to favour high species richness and abundance of the fauna. 3. We describe results from experimental wildflower strips in...

Data from: The effects of inbreeding, genetic dissimilarity and phenotype on male reproductive success in a dioecious plant

Frédéric Austerlitz, Gabriela Gleiser, Sara Teixeira & Giorgina Bernasconi
Pollen fate can strongly affect the genetic structure of populations with restricted gene flow and significant inbreeding risk. We established an experimental population of inbred and outbred Silene latifolia plants to evaluate the effects of (i) inbreeding depression, (ii) phenotypic variation and (iii) relatedness between mates on male fitness under natural pollination. Paternity analysis revealed that outbred males sired significantly more offspring than inbred males. Independently of the effects of inbreeding, male fitness depended on...
