Understanding changes to local communities brought about by biological invasions is important for conserving biodiversity and maintaining environmental stability. Scale insects (Hemiptera: Coccoidea) are a diverse group of insects well known for their invasion potential and ability to modify local abundance of multiple insect groups. Here, we tested how the presence of crape myrtle bark scale ( Acanthococcus lagerstroemiae, CM...
Stage‐specific drivers of Pacific hake ( Merluccius productus ) recruitment in the California Current EcosystemNARA Subscribed
Understanding environmental drivers of recruitment variability in marine fishes remains an important challenge in fish ecology and fisheries management. We developed a conceptual life‐history model for Pacific hake ( Merluccius productus ) along the west coast of the United States and Canada to generate stage‐specific and spatiotemporally‐specific hypotheses regarding the oceanographic and biological variables that likely infl...
Intensive land use activities, such as agriculture, are a leading cause of biodiversity loss and can have lasting impacts on ecological systems. Yet, few studies have investigated how land‐use legacies impact phylogenetic diversity (the total amount of evolutionary history in a community) or how restoration activities might mitigate legacy effects on biodiversity. We studied ground‐layer plant communities in 27 pairs of Remnan...
Plant domestication slows pest evolutionNARA Subscribed
Agricultural practices such as breeding resistant varieties and pesticide use can cause rapid evolution of pest species, but it remains unknown how plant domestication itself impacts pest contemporary evolution. Using experimental evolution on a comparative phylogenetic scale, we compared the evolutionary dynamics of a globally important economic pest – the green peach aphid ( Myzus persicae ) – growing on 34 plant taxa, repre...
Habitat patch shape, not corridors, determines herbivory and fruit production of an annual plantNARA Subscribed
Habitat corridors confer many conservation benefits by increasing movement of organisms between habitat patches, but the benefits for some species may exact costs for others. For example, corridors may increase the abundance of consumers in a habitat to the detriment of the species they consume. In this study we assessed the impact of corridors on insect herbivory of a native plant, Solanum americanum , in large‐scale, experim...
A study of total and particle‐associated bacteria in the Northwest Mediterranean revealed notable relationships with depth. Cell‐specific leucine incorporation rates by total bacteria decreased significantly with depth (to 380 m), best fitting the power function log (rate) = 2.1–0.54 log (depth), r 2 = 0.57, P = r 2 = 0.74, P =
