- Cultural sediments containing significant amounts of fish bone at Langenesværet, Vesterålen, Northern Norway provide an opportunity to characterise activity during and prior to the establishment of a late medieval commercial fishing station (fiskevaer). Radiometric and AMS dating techniques are used to establish a chronology for the deposits, while activities associated with the sediments are characterised fossil insect faunas. The results highlight a series of problems with the dating of the heavily disturbed organic deposits of many archaeological sites, and the need for greater care in sample selection and interpretation.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This report stems from work commissioned by English Nature into the role of largeherbivores in the post-glacial landscape of Britain and the potential for using free-ranginggrazing animals to create and maintain diverse landscape mosaics in modern conditions.Some aspects may be disputed or considered controversial; it is an active field of research.Therefore we stress that the views expressed are those of the authors at the current time.Subsequent research may confirm our views or lead us to modify them.We hope they will be useful in future discussions, both within English Nature and inconservation land-management circles more generally.

BugsCEP : Coleopteran Ecology Package (software)
- 2006
-
Annan publikation (populärvet., debatt m.m.)abstract
- BugsCEP is a research and teaching aid for palaeoentomology, entomology and ecology. As well as habitat and distribution data, it includes tools for climate and environmental reconstruction, and facilities for storing site based abundance/collection data. A variety of searching and reporting functions greatly augment the efficiency of beetle based research. Bugs is built around a comprehensive database of beetle ecology and European fossil records which has been accumulated over the past 20 years.

Tidskriftsartikel (refereegranskat)abstract
- An understanding of how genes move between and within populations of parasitic nematodes is important in combating the evolution and spread of anthelmintic resistance. Much has been learned by studying mitochondrial DNA markers, but autosomal markers such as microsatellites have been applied to only a few nematode species, despite their many advantages for studying gene flow in eukaryotes. Here, we describe the isolation of 307 microsatellites from Trichostrongylus tenuis, an intestinal nematode of red grouse. High levels of variation were revealed at sixteen microsatellite loci (including three sex-lined loci) in 111 male T. tenuis nematodes collected from four hosts at a single grouse estate in Scotland (average He = 0.708; mean number of alleles = 12.2). A population genetic analysis detected no deviation from panmixia either between (F(ST) = 0.00) or within hosts (F(IS) = 0.015). We discuss the feasibility of developing microsatellites in parasitic nematodes and the problem of null alleles. We also describe a novel 146-bp repeat element, TteREP1, which is linked to two-thirds of the microsatellites sequenced and is associated with marker development failure. The sequence of TteREP1 is related to the TcREP-class of repeats found in several other trichostrongyloid species including Trichostrongylus colubriformis and Haemonchus contortus.
