Plasma treatment is a promising way of surface modification. In the case of heterogeneous materials, the study of the local properties of surfaces at the structural level is of interest. The changes of the surface of polyurethane (two-phase polymer, elastic modulus 25 MPa) under the action of argon plasma were studied by atomic force microscopy and finite-element modeling. The initial structure of polymer (stiff fibrils non-uniformly distributed in a softer matrix) is gradually destroyed during...

Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 localities across the Arctic. We focus on parasitoids in a wide-spread habitat, Dryas heathlands, and describe parasitoid community composition in terms of larval host use (i.e. parasitoid use of herbivorous Lepidoptera versus pollinating Diptera)...
