Hemispheric Asymmetries in Biodiversity—A Serious Matter for Ecology
Although the poles are less diverse than the tropics, this decline shows substantial asymmetries between the hemispheres, suggesting that responses to environmental change may differ substantially inExpand

Acclimation effects on thermal tolerances of springtails from sub-Antarctic Marion Island: indigenous and invasive species.
Collembola are abundant and functionally significant arthropods in sub-Antarctic terrestrial ecosystems, and their importance has increased as a consequence of the many invasive alien species thatExpand

Effects of removing sea urchins (Strongylocentrotus droebachiensis): Stability of the barren state and succession of kelp forest recovery in the east Atlantic
Stability properties of the barren state of a kelp forest-sea urchin system were studied in northern Norway. The ability of the sea urchin Strongylocentrotus droebachiensis to maintain highExpand

Phenotypic plasticity mediates climate change responses among invasive and indigenous arthropods
Synergies between global change and biological invasion have been identified as a major potential threat to global biodiversity and human welfare. The global change-type drought characteristic ofExpand

Temperature‐size relations from the cellular‐genomic perspective
A family of empirically based ecological ‘rules’, collectively known as temperature‐size rules, predicts larger body size in colder environments. This prediction is based on studies demonstratingExpand

Transport of Ixodes ricinus infected with Borrelia species to Norway by northward-migrating passerine birds.
Birds are capable of transporting ticks and, consequently, tick-borne pathogens over long distances and across geographical barriers such as oceans and deserts. The purpose of this study was toExpand

Transport of Ticks by Migratory Passerine Birds to Norway
Abstract Ticks can be transported over large distances and across geographical barriers by avian hosts. During the spring migrations of 2003 to 2005, 9,768 passerine birds from 4 bird observatoriesExpand

Experimental manipulation of the winter surface ice layer: the effects on a High Arctic soil microarthropod community.
The effect of patch size on the tolerance of the soil microarthropod population to an experimentally induced environmental catastrophe, a thick surface ice layer, was studied at a High Arctic siteExpand

Detection of Babesia divergens in southern Norway by using an immunofluorescence antibody test in cow sera
BackgroundThe incidence of bovine babesiosis, caused by Babesia divergens (Apicomplexa: Piroplasmida) has decreased markedly since the 1930 s, but may re-emerge as a consequence of climate change andExpand

Genome size in arthropods; different roles of phylogeny, habitat and life history in insects and crustaceans
Abstract Despite the major role of genome size for physiology, ecology, and evolution, there is still mixed evidence with regard to proximate and ultimate drivers. The main causes of large genomeExpand
