Testing the enemy release hypothesis: a review and meta-analysis
One of the most cited hypotheses explaining the inordinate success of a small proportion of introduced plants that become pests is the ‘natural enemies hypothesis’. This states that invasiveExpand
How does elevated carbon dioxide (CO2) affect plant–herbivore interactions? A field experiment and meta‐analysis of CO2‐mediated changes on plant chemistry and herbivore performance
First, we report the results of the longest-known field study (9 years) to examine the effects of elevated carbon dioxide (CO2) on leaf miner densities in a scrub-oak community at Kennedy SpaceExpand
How Risky is Biological Control
The potential harmful effects of non—indigenous species introduced for biological control remain an important unanswered question, which we addressed by undertaking a literature review. There are fewExpand
Sex‐biased herbivory: a meta‐analysis of the effects of gender on plant‐herbivore interactions
We used sets of meta-analyses to review the evidence of sex-biased herbivory in dioecious plants as well as intersexual differences in plant characteristics that might affect herbivores, ThirtythreeExpand
What makes a successful biocontrol agent? A meta-analysis of biological control agent performance
We qualitatively reviewed the biocontrol literature in two major journals, Biological Control and Environmental Entomology, over the past 10 years by scoring 878 studies into 11 biocontrol-orientedExpand
Ecology: Theories and Applications
Presenting an overview of ecology (evolutionary, behavioural, population, community and applied) - this text covers all of the essentials required by beginning students.
Perfect is best: low leaf fluctuating asymmetry reduces herbivory by leaf miners
Fluctuating asymmetry (FA) represents small, random variation from symmetry and can be used as an indicator of plant susceptibility to herbivory. We investigated the effects of FA of two oak species,Expand
Risks of species introduced for biological control
Numerous biological control introductions have adversely affected non-target native species. Although many of these problems occurred in the early days of biological control, some are recent. BecauseExpand
Quality or quantity: the direct and indirect effects of host plants on herbivores and their natural enemies
Resource quality (plant nitrogen) and resource quantity (plant density) have often been argued to be among the most important factors influencing herbivore densities. A difficulty inherent in theExpand
CO2 Elicits Long-Term Decline in Nitrogen Fixation
Rising atmospheric carbon dioxide ( C a), a product of fossil fuel burning, land-use change, and cement manufacture, is expected to cause a large carbon sink in land ecosystems, partly mitigatingExpand
