    Florivory and pollinator visitation: a cautionary tale

    Florivory, or damage to flowers by herbivores, can make flowers less attractive to pollinators, potentially resulting in reduced plant fitness. However, few studies have combined observations with experiments to assess the causal link between florivory and pollination. In a recent study published in AoB PLANTS, Tsuji et al. conducted field observations and experiments to study […] More

    Genepool of a year-long bean crop, Phaseolus dumosus

    Studying the relationships between major crops and the secondary genepools of related species that are more resistant to climate challenges, Mina-Vargas et al. employ nuclear and chloroplast genetic markers to carry out a comprehensive investigation of the genetic diversity of a year-long staple Guatamalan legume crop. They find that the common bean, Phaseolus dumosus, which […] More
