Understanding the drivers of biodiversity in cities is a central goal of urban ecology. There is currently intense scientific and public interest in the factors that influence pollinator diversity in cities and their surroundings. Existing studies po

Dioecious plants can exhibit sexual dimorphism across a suite of plant traits, including susceptibility to herbivory and secondary chemistry. One hypothesis is that because of greater costs of reproduction in females, males should grow faster and inv

Biological control is a popular tool for invasive species management, but its success in nature is difficult to predict. One risk is that invasive plants, which may have adapted to lower herbivore pressure in the introduced range, could rapidly evolv

Premise of research. The ecological impacts of invasive species on native ecosystems is a topic of intense debate. Recent reviews and meta-analyses have cast doubt on the long-held idea that the im...

The introduction of an alien plant is widely assumed to have negative consequences for the pollinator-mediated fitness of nearby natives. Indeed, a number of studies, including a highly cited meta-analysis, have concluded that the trend for such inte

Background and aims The study of the evolution of floral traits has generally focused on pollination as the primary driver of selection. However, herbivores can also impose selection on floral traits through a variety of mechanisms, including florivo

Agricultural landscapes vary widely in the degree to which they provide natural habitat. This is in spite of the fact that the availability of natural habitat has been identified as a critical factor influencing the diversity and abundance of benefic
