Anthropogenic nutrient inputs into native ecosystems cause fluctuations in resources that normally limit plant growth, which has important consequences for associated food webs. Such inputs from agricultural and urban habitats into nearby natural sys

Summary 1. An important recent advance in food web ecology has been the application of theory regarding spatial gradients to studies of the factors that affect animal population dynamics. Building on extensive studies of the Spartina alterniflora foo

1. Omnivores by definition eat both plants and animals. However, little is known about how diet macronutrient content affects omnivore performance, or the extent to which they can regulate macronutrient intake. We assessed these questions using the s

1. Predator and alternative food density are important factors influencing herbivore suppression by generalist predators. Herbivore suppression can be reduced if predators forage preferentially on alternative foods. Cannibalism can increase at high p

1. Entry of substantial numbers of natural enemies from outside a habitat can have profound impacts on food web structure in the recipient habitat, but underlying mechanisms are poorly understood, including the role of relative predator fitness in so

The expression of plant defenses is thought to entail costs (e.g., the allocation of resources away from growth or reproduction) that constrain the evolution of plant genotypes maximally defended against herbivores. Although central to the ecological

As herbivory often elicits systemic changes in plant traits, indirect interactions via induced plant responses may be a pervasive feature structuring herbivore communities. Although the importance of this phenomenon has been emphasised for herbivorou

Herbivores induce systemic changes in plant traits, and the strength of these induced responses is often associated with the degree of vascular connectivity that links damaged and undamaged plant tissues. Although this phenomenon is known to occur ab

The potato leafhopper, Empoasca fabae (Harris) (Hemiptera: Cicadellidae), is an emerging pest of potato and insecticide applications to control this insect have increased in recent years. Based on field observations of leafhopper–crop dynamics, how
