Ecological networks have a long history in ecology, and a recent increase in network
analyses across environmental gradients has revealed important changes in their structure …

Inferring biotic interactions from functional, phylogenetic and geographical proxies remains
one great challenge in ecology. We propose a conceptual framework to infer the backbone …

By depicting who eats whom, food webs offer descriptions of how groupings in nature
(typically species or populations) are linked to each other. For asking questions on how food …

Global environmental changes threaten biodiversity and the interactions between species,
and food-web approaches are being used increasingly to measure their community-wide …

Determining how and why organisms interact is fundamental to understanding ecosystem
responses to future environmental change. To assess the impact on plant‐pollinator …

We here attempt to show, using three broad insect groups–Lepidoptera (mainly leaf-
chewing larval herbivores and nectar-sucking adults), parasitic Hymenoptera (mainly …

The occurrence of complex networks of interactions among species not only relies on
species co‐occurrence, but also on inherited traits and evolutionary events imprinted in …

The use of alternative hosts imposes divergent selection pressures on parasitoid
populations. In response to selective pressures, these populations may follow different …

Coevolutionary selection is a powerful process shaping species interactions and
biodiversity. Anthropogenic global environmental change is reshaping planetary …

Host specialization in aphid parasitoids is important both from a theoretical and an applied
point of view. It arises from various ecological mechanisms involving their interactions with …
