Increased susceptibility to enemies following introduction in the invasive plant Silene latifolia
One of the influential hypotheses invoked to explain why species become invasive following introduction is that release from natural enemies favours a shift in investment from defence to traitsExpand

Development of the solitary endoparasitoid Microplitis demolitor: host quality does not increase with host age and size
Abstract.  1. Many studies examining the relationship between host size, an index of host quality, and parasitoid fitness use development time and/or adult parasitoid size as currencies of fitness,Expand

Effects of long‐term cutting in a grassland system: perspectives for restoration of plant communities on nutrient‐poor soils
Abstract The upper courses of brook valley systems harbour Nardo‐Galion saxatilis communities characteristic of oligotrophic soils under low‐intensity farming. Most of these communities haveExpand

Distribution and colonisation ability of three parasitoids and their herbivorous host in a fragmented landscape
Summary Habitat fragmentation can disrupt communities of interacting species even if only some of the species are directly affected by fragmentation. For instance, if parasitoids disperse less wellExpand

Host Fidelity of the Pollinator Guilds of Silene dioica and Silene latifolia: Possible Consequences for Sympatric Host Race Differentiation of a Vectored Plant Disease
Host fidelity can play an important role in sympatric host race formation of phytophagous insects by providing a mechanism for prezygotic reproductive isolation. Similarly, but less recognized, hostExpand

The effects of host weight at parasitism on fitness correlates of the gregarious koinobiont parasitoid Microplitis tristis and consequences for food consumption by its host, Hadena bicruris
Gregarious koinobiont parasitoids attacking a range of host sizes have evolved several mechanisms to adapt to variable host resources, including the regulation of host growth, flexibility in larvalExpand

Plant population size and isolation affect herbivory of Silene latifolia by the specialist herbivore Hadena bicruris and parasitism of the herbivore by parasitoids
Habitat fragmentation can affect levels of herbivory in plant populations if plants and herbivores are differentially affected by fragmentation. Moreover, if herbivores are top–down controlled byExpand

Fine-scale spatial genetic structure and gene dispersal in Silene latifolia
Plants are sessile organisms, often characterized by limited dispersal. Seeds and pollen are the critical stages for gene flow. Here we investigate spatial genetic structure, gene dispersal and theExpand

A plant pathogen reduces the enemy–free space of an insect herbivore on a shared host plant
An important mechanism in stabilizing tightly linked host–parasitoid and prey–predator interactions is the presence of refuges that protect organisms from their natural enemies. However, the presenceExpand
