Prioritization of introduction pathways is seen as an important component of the management of biological invasions. We address whether established alien plants, mammals, freshwater fish and terrestrial invertebrates with known ecological impacts are associated with particular introduction pathways (release, escape, contaminant, stowaway, corridor and unaided). We used the information from...

This article considers the potential for insurer competition to improve health system performance by strengthening purchasing. Economic theory suggests that insurer competition will enhance efficiency if: (1) people have free choice of insurer, (2) competition is based on price and quality rather than risk selection and (3) insurers have tools to influence health care costs and quality. The...

Dans la Vie d’une famille juive, Edith Stein montre que, dans sa jeunesse, elle envisageait sa destinée personnelle en opposition avec son milieu, malgré la grande affection qu'elle nourrissait pour sa famille. Ce qui domine sa vie alors est son sens de l'amitié et son goût pour l'étude et surtout le travail philosophique. C. Betschart souligne que ce sens de son histoire personnelle doit...

Aim To predict the fate of alpine interactions involving specialized species, using a monophagous beetle and its host plant as a case study.Location The Alps.Methods We investigated genetic structuring of the herbivorous beetle Oreina gloriosa and its specific host-plant Peucedanum ostruthium. We used genome fingerprinting (in the insect and the plant) and sequence data (in the insect)...

Aim Human activities have led to the spread and establishment of increasing numbers of non-native species. Here we assess whether non-native plant and vertebrate species have affected species compositions within and across Europe and North America. We also assess the effects of intra-continental species exchange using the example of vertebrates.Location European countries and North America...

Aim To provide the first comparative overview on the current numbers of alien species that invade representative European terrestrial and freshwater habitats for a range of taxonomic groups. Location Europe. Methods Numbers of naturalized alien species of plants, insects, herptiles, birds and mammals occurring in 10 habitats defined according to the European Nature Information System (EUNIS) were...

Aim: Geographic body size patterns of mammals and birds can be partly understood under the framework of Bergmann's rule. Climatic influences on body size of invertebrates, however, appear highly variable and lack a comparable, generally applicable theoretical framework. We derived predictions for body size–climate relationships for spiders from the literature and tested them using three...
