Abstract: The genus Megalothorax Willem, 1900 is redefined along with a redescription of the type species M. minimus Willem, 1900 and the description of five new species (M. granulosus, sp. nov., M. nigropunctatus, sp. nov., M. perspicillum, sp. nov., M. svalbardensis, sp. nov. and M. willemi, sp. nov.). We describe and comment on broad sets of discriminating characters for Megalothorax systematics. For the first time, trichobothria are recorded for Neelipleona, probably of generic importance. The described species are provided with DNA data (COI, 16S and 28S) and included in a molecular-based phylogenetic analysis. The traditional distinction between minimus-group and incertus-group is discussed in the light of DNA and morphology components. A key to the worldwide Megalothorax species is provided.

Torsten Wappler, Thomas Denk. (2011). Herbivory in early Tertiary Arctic forests (Vol. 310).
Abstract: Early Tertiary High Arctic forest ecosystems are unique in that they have no equivalent among modern forests. Today, no forest ecosystem exists at such high latitudes. To assess the potential role of herbivory during the early Tertiary warm period at high latitudes, we have surveyed 1567 fossil angiosperm leaves from Svalbard for the presence or absence of 35 insect damage types (DTs). Our investigation for the first time uncovered a wealth of insect trace fossils from the early Tertiary northern high latitudes. These include galls, mines, and feeding traces on fossil leaves. Most of the folivory includes unspecific external foliage feeding that cannot be ascribed to a particular group of insects. Exceptions are the mining damage types that are most similar to those made by leaf-mining moths (Lepidoptera: Gracillaroidea). Nevertheless, the abundance of folivory indicates that herbivorous insects were an important component of the forests thriving in the Arctic realm. The observed change in insect herbivory from the Middle Paleocene to the Late Eocene/Early Oligocene in Spitsbergen may be attributed to climatic variables because they influence insect life-cycle timing, population density, and geographic range.

. (2009). Impact of ocean acidification on a key Arctic pelagic mollusc (Limacina helicina). BIOGEOSCIENCES, 6, 1877–1882.
Abstract: Thecosome pteropods (shelled pelagic molluscs) can play an important role in the food web of various ecosystems
and play a key role in the cycling of carbon and carbonate. Since they harbor an aragonitic shell, they could be
very sensitive to ocean acidification driven by the increase of anthropogenic CO2 emissions. The impact of changes in
the carbonate chemistry was investigated on Limacina helicina, a key species of Arctic ecosystems. Pteropods were kept
in culture under controlled pH conditions corresponding to pCO2 levels of 350 and 760μatm. Calcification was estimated using a fluorochrome and the radioisotope 45Ca. It exhibits a 28% decrease at the pH value expected for 2100
compared to the present pH value. This result supports the concern for the future of pteropods in a high-CO2 world, as
well as of those species dependent upon them as a food resource.
A decline of their populations would likely cause
dramatic changes to the structure, function and services of
polar ecosystems.
