Land-bridge calibration of molecular clocks and the post-glacial colonization of Scandinavia by the Eurasian field vole Microtus agrestis
Phylogeography interprets molecular genetic variation in a spatial and temporal context. Molecular clocks are frequently used to calibrate phylogeographic analyses, however there is mounting evidence that molecular rates decay over the relevant timescales. It is therefore essential that an appropriate rate is determined, consistent with the temporal scale of the...Herman, Jeremy S ; McDevitt, Allan D ; Kawalko, Agato ; Jaarolo, Maarit ; Wójcik, J M …

Between the Balkans and the Baltic: Phylogeography of a common vole Mitochondrial DNA lineage limited to Central Europe
The common vole (Microtus arvalis) has been a model species of small mammal for studying end-glacial colonization history. In the present study we expanded the sampling from central and eastern Europe, analyzing contemporary genetic structure to identify the role of a potential ‘northern glacial refugium’, i.e. a refugium at a...Stojak, Joanna ; McDevitt, Allan D ; Herman, Jeremy S ; Kryštufek, Boris ; Uhlíková, Jitka …

When ivory came from the seas. On some traits of the trade of raw and carved sea-mammal ivories in the Middle Ages
Even if it played a part, it is not so much the lesser availability of elephant ivory as the Norse expansion in the Northern Atlantic that brought the success of walrus ivory throughout Western Europe and far beyond. The strength of demand did not only bring the extinction of the...Dectot, Xavier

Ecology and Genetic Structure of the Parasitoid Phobocampe confusa (Hymenoptera: Ichneumonidae) in Relation to Its Hosts, Aglais Species (Lepidoptera: Nymphalidae)
The biology of parasitoids in natural ecosystems remain very poorly studied, though they are key species for their functioning. Here we focused on Phobocampe confusa, a Nymphalini specialist, responsible for high mortality rates in charismatic butterfly species in Europe (genus Aglais). We studied its ecology and genetic structure in connection...Audusseau , Hélène ; Baudrin, Gaspard ; Shaw, Mark R ; Keehnen, Naomi L P ; Schmucki, Reto …

The first records of the pictured-winged fly Homalocephala bimaculata (Wahlberg, 1838) (Diptera, Ulidiidae) from Norway
The picture-winged fly Homalocephala bimaculata (Wahlberg, 1838) is reported from Norway for the first time bringing to five the number of species of Homalocephala Zetterstedt, 1838 reported from the country. H. bimaculata is recorded from Hvaler, Viken, and Oslo, Oslo, and, based on numerous and scattered records, the species is...Gustad, Jørn R ; Græsdal, Arve G ; MacGowan, Iain

A curated DNA barcode reference library for parasitoids of northern European cyclically outbreaking geometrid moths
Large areas of forests are annually damaged or destroyed by outbreaking insect pests. Understanding the factors that trigger and terminate such population eruptions has become crucially important, as plants, plant-feeding insects, and their natural enemies may respond differentially to the ongoing changes in the global climate. In northernmost Europe, climate-driven...Nyman, Tommi ; Wutke, Saskia ; Koivisto, Elina ; Klemola, Tero ; Shaw, Mark R …

Range-wide whole-genome resequencing of the brown bear reveals drivers of intraspecies divergence
Population-genomic studies can shed new light on the effect of past demographic processes on contemporary population structure. We reassessed phylogeographical patterns of a classic model species of postglacial recolonisation, the brown bear ( ), using a range-wide resequencing dataset of 128 nuclear genomes. In sharp contrast to the erratic geographical...de Jong, Menno J ; Niamir, Aidin ; Wolf, Magnus ; Kitchener, Andrew C ; Lecomte, Nicolas …

Textiles in a Viking Age hoard: Identifying ephemeral traces of textiles in metal corrosion products
This paper presents a novel method and terminology to identify and describe textiles from ephemeral traces in metal corrosion products. Since the 1980s, mineralised textiles (positive and negative casts in Janaway’s terminology) have been an important source of archaeological evidence. A major issue now is the identification of textiles in...Davis, Mary ; Harris, Susanna
