temporal genetic variation of the red fox vulpes vulpes across western europe and the british isles
Quaternary Science Reviews, 2012Co-Authors: Ceiridwen J Edwards, Mark J Statham, Stephen Harris, Carl D Soulsbury, Dave Wall, G Dolf, Graziella Iossa, Phillip J Baker, Benjamin N Sacks, Daniel G BradleyAbstract:Quaternary climatic fluctuations have had profound effects on the phylogeographic structure of many species. Classically, species were thought to have become isolated in peninsular refugia, but there is limited evidence that large, non-polar species survived outside traditional refugial areas. We examined the phylogeographic structure of the red fox (vulpes vulpes), a species that shows high ecological adaptability in the western Palaearctic region. We compared mitochondrial DNA sequences (cytochrome b and control region) from 399 modern and 31 ancient individuals from across Europe. Our objective was to test whether red foxes colonised the British Isles from mainland Europe in the late Pleistocene, or whether there is evidence that they persisted in the region through the Last Glacial Maximum. We found red foxes to show a high degree of phylogeographic structuring across Europe and, consistent with palaeontological and ancient DNA evidence, confirmed via phylogenetic indicators that red foxes were persistent in areas outside peninsular refugia during the last ice age. Bayesian analyses and tests of neutrality indicated population expansion. We conclude that there is evidence that red foxes from the British Isles derived from central European populations that became isolated after the closure of the landbridge with Europe.

efficient species identification of pine marten martes martes and red fox vulpes vulpes scats using a 5 nuclease real time pcr assay
Conservation Genetics, 2008Co-Authors: Catherine Oreilly, Peter D Turner, Jacinta Mullins, Mark J Statham, Declan T OmahonyAbstract:Monitoring wildlife species by DNA identification of samples collected non-invasively is an important tool in conservation management. DNA identification of species from faecal (scat) samples is problematic due to the small quantities and poor quality of the DNA isolated from such samples. This study demonstrates the use of real-time PCR technology in the identification of red fox (vulpes vulpes) and pine marten (Martes martes). It is shown that real-time PCR can be used to identify fox and pine marten by either melting curve analysis (Tm determination) with SYBR Green 1 detection or by the use of species specific fluorogenic probes. The technique is shown to work efficiently with scat DNA.

detection of anaplasma phagocytophilum in red foxes vulpes vulpes and raccoon dogs nyctereutes procyonoides from brandenburg germany
Ticks and Tick-borne Diseases, 2014Co-Authors: Vera Hartwig, Friederike D Von Loewenich, Christoph Schulze, Reinhard K Straubinger, A Daugschies, Viktor DyachenkoAbstract:Anaplasma phagocytophilum is an obligate intracellular and tick-transmitted bacterium, which causes granulocytic anaplasmosis in animals and humans. Although infection with A. phagocytophilum in domestic animals and vector ticks is documented, there is sparse information on the occurrence of A. phagocytophilum in wild animals. Red foxes (vulpes vulpes) as well as raccoon dogs (Nyctereutes procyonoides) are wildlife species highly abundant in certain areas of Germany and represent a potential wildlife reservoir for zoonotic diseases. To obtain data about the occurrence of A. phagocytophilum in these animals, red fox and raccoon dog carcasses (hunted or found dead) were collected from January to September 2009 in the Federal State of Brandenburg, Germany. Lung tissue samples were subjected to DNA extraction and were examined for the presence of A. phagocytophilum DNA by means of real-time PCR. Anaplasma phagocytophilum was detected in 10 out of 122 (8.2%) lungs of red foxes and in 3 out of 13 (23%) lungs of raccoon dogs. To the best of our knowledge, A. phagocytophilum was detected for the first time in red foxes and raccoon dogs in Germany.

a study on the predilection sites of trichinella spiralis muscle larvae in experimentally infected foxes alopex lagopus vulpes vulpes
Acta Veterinaria Scandinavica, 1994Co-Authors: Christian Moliin Outzen Kapel, S A Henriksen, H H Dietz, P Henriksen, Peter NansenAbstract:: Studies were carried out on the predilection sites of Trichinella spiralis muscle larvae in experimentally infected arctic foxes (Alopex lagopus) and silver foxes (vulpes vulpes) reared in cages. The highest number of larvae per gram tissue was found in the muscles of the legs, eyes, diaphragm, and tongue. The 2 fox species showed no significant differences with regard to predilection sites.

Henriksen, P. Nansen: A study on the predilection sites of Trichinella spiralis muscle larvae in experimentally infected foxes (Alopex lagopus, vulpes vulpes). Acta vet. scand. 1994, 35, 125-132.–Studies were carried out on the predilection sites of Trichinella spiralis muscle larvae in experimentally infected arctic foxes (Alopex lagopus) and silver foxes (vulpes vulpes) reared in cages. The highest number of larvae per gramme tissue was found in the muscles of the legs, eyes, diaphragm, and tongue. The 2 fox species showed no significant differences with regard to predilection sites.
