▪ Abstract Phytophagous insects and their natural enemies make up one of the largest and
most diverse groups of organisms on earth. Ecological processes, in particular negative …

Understanding how arthropod pests and their natural enemies interact in complex
agroecosystems is essential for pest management programmes. Theory predicts that prey …

Understanding species' interactions and the robustness of interaction networks to species
loss is essential to understand the effects of species' declines and extinctions. In most …

We present a comprehensive approach to detect pattern in assemblages of plant and animal
species linked by interactions such as pollination, frugivory or herbivory. Simple structural …

How networks of ecological interactions are structured has a major impact on their
functioning. However, accurately resolving both the nodes of the webs and the links …

Habitat fragmentation is the transformation of once‐extensive landscapes into smaller,
isolated remnants surrounded by new types of habitat. There is ample evidence of …

1. How food webs are structured will affect how species dynamically interact. To date, the
construction of quantitative food webs has largely been based on morphological species …

Not all species are likely to be equally affected by habitat fragmentation; thus, we evaluated
the effects of size of forest remnants on trophically linked communities of plants, leaf‐mining …

Summary 1 Quantitative host–parasitoid food webs are descriptions of community structure
that include data on the abundance of hosts and parasitoids, and the frequency of links …

1. Most communities of insect herbivores are unlikely to be structured by resource
competition, but they may be structured by apparent competition mediated by shared natural …
