Assessment of intraspecific mtDNA variability of European Ixodes ricinus sensu stricto (Acari: Ixodidae)

Casati, Simona ; Bernasconi, Marco V. ; Gern, Lise ; Piffaretti, Jean-Claude

In: Infection, Genetics and Evolution, 2008, vol. 8, no. 2, p. 152-158

The Ixodes ricinus complex is composed of 14 species distributed worldwide. Some members of this complex are involved in the transmission of a number of diseases to animals and humans, in particular Lyme borreliosis, tick-borne encephalitis, ehrlichiosis and babesiosis. While the phylogenetic relationships between species of the I. ricinus complex have been investigated in the past,...

Attitudes toward Corporate Responsibilities in Western Europe and in Central And East Europe

Furrer, Olivier ; Egri, Carolyn P. ; Ralston, David A. ; Danis, Wade M. ; Reynaud, Emmanuelle ; Naoumova, Irina ; Molteni, Mario ; Starkus, Arunas ; Darder,Lecturer Fidel León ; Dabic, Marina ; Furrer-Perrinjaquet, Amandine

In: Management International Review, 2010, vol. 50, no. 3, p. 379-398

This study investigated the attitudes toward social, economic, and environmental corporate responsibilities of 3064 current managers and business students in 8 European countries. Participants in Western European countries had significantly different perspectives on the importance of these corporate responsibilities (CR) than those in Central and East European countries. Within each country,...

Body size–climate relationships of European spiders

Entling, Wiebke ; Schmidt-Entling, Martin H. ; Bacher, Sven ; Brandl, Roland ; Nentwig, Wolfgang

In: Journal of Biogeography, 2009///doi: 10.1111/j.1365-2699.2009.02216.x

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...

Climate oscillations and species interactions: large-scale congruence but regional differences in the phylogeographic structures of an alpine plant and its monophagous insect

Borer, Matthias ; Arrigo, Nils ; Buerki, Sven ; Naisbit, Russell E. ; Alvarez, Nadir

In: Journal of Biogeography, 2012, p. -

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)...

COI gene and ecological data suggest size-dependent high dispersal and low intra-specific diversity in free-living terrestrial protists (Euglyphida: Assulina)

Lara, Enrique ; Heger, Thierry J. ; Scheihing, Rodrigo ; Mitchell, Edward A. D.

In: Journal of Biogeography, 2010, vol. 38, no. 4, p. 640-650

Aim Propagule size and ecological requirements are believed to be major factors influencing the passive dispersal of free-living terrestrial protists. We compared the colonization potential of three closely related testate amoeba species (Assulina muscorum, A. seminulum, A. scandinavica, ranging from 40 to 100 μm in length). Location Europe.
