The discovery of three new hare lagoviruses reveals unexplored viral diversity in this genus.

Virus Evol 2019 Jan 9;5(1):vez005. Epub 2019 Apr 9.

Marie Bashir Institute for Infectious Diseases and Biosecurity, Charles Perkins Centre, School of Life and Environmental Sciences and Sydney Medical School, The University of Sydney, Sydney, New South Wales, Australia.

Our knowledge of mammalian viruses has been strongly skewed toward those that cause disease in humans and animals. However, recent metagenomic studies indicate that most apparently healthy organisms carry viruses, and that these seemingly benign viruses may comprise the bulk of virus diversity. The bias toward studying viruses associated with overt disease is apparent in the lagoviruses (family that infect rabbits and hares: although most attention has been directed toward the highly pathogenic members of this genus-rabbit haemorrhagic disease virus and European brown hare syndrome virus-a number of benign lagoviruses have also been identified.

Alpine glacial relict species losing out to climate change: The case of the fragmented mountain hare population (Lepus timidus) in the Alps.

Glob Chang Biol 2018 07 13;24(7):3236-3253. Epub 2018 Mar 13.

Forest Research Institute of Baden-Württemberg, Freiburg, Germany.

Alpine and Arctic species are considered to be particularly vulnerable to climate change, which is expected to cause habitat loss, fragmentation and-ultimately-extinction of cold-adapted species. However, the impact of climate change on glacial relict populations is not well understood, and specific recommendations for adaptive conservation management are lacking. We focused on the mountain hare (Lepus timidus) as a model species and modelled species distribution in combination with patch and landscape-based connectivity metrics. Read More

Widespread introgression of mountain hare genes into Fennoscandian brown hare populations.

PLoS One 2018 25;13(1):e0191790. Epub 2018 Jan 25.

Department of Environmental and Biological Sciences, University of Eastern Finland, Joensuu, Finland.

In Fennoscandia, mountain hare (Lepus timidus) and brown hare (Lepus europaeus) hybridize and produce fertile offspring, resulting in gene flow across the species barrier. Analyses of maternally inherited mitochondrial DNA (mtDNA) show that introgression occur frequently, but unavailability of appropriate nuclear DNA markers has made it difficult to evaluate the scale- and significance for the species. The extent of introgression has become important as the brown hare is continuously expanding its range northward, at the apparent expense of the mountain hare, raising concerns about possible competition.

How genetic data improve the interpretation of results of faecal glucocorticoid metabolite measurements in a free-living population.

PLoS One 2017 23;12(8):e0183718. Epub 2017 Aug 23.

Department of Biomedical Sciences, University of Veterinary Medicine, Veterinärplatz 1, Vienna, Austria.

Measurement of glucocorticoid metabolites (GCM) in faeces has become a widely used and effective tool for evaluating the amount of stress experienced by animals. However, the potential sampling bias resulting from an oversampling of individuals when collecting "anonymous" (unknown sex or individual) faeces has rarely been investigated. We used non-invasive genetic sampling (NIGS) to investigate potential interpretation errors of GCM measurements in a free-living population of mountain hares during the mating and post-reproductive periods.

Steel-Jawed Leghold Traps and Killing Neck Snares: Similar Injuries Command Change to Agreement on International Humane Trapping Standards.

J Appl Anim Welf Sci 2017 Apr-Jun;20(2):198-203. Epub 2017 Feb 16.

b Retired Problem Wildlife Specialist , Alberta Agriculture, Rocky Mountain House , Alberta , Canada.

According to the Agreement on International Humane Trapping Standards (AIHTS), which was signed by the European Community, Canada, and Russia in 1997, killing devices used for the capture of canids and other fur-bearing nonhuman animals should render an animal irreversibly unconscious within 300 s. However, killing neck snares are not included in the agreement. In this commentary, a parallel is drawn between injuries caused by steel-jawed leghold traps, which have been banned by the AIHTS signatory countries, and killing neck snares to demonstrate that these snares should also be included in international humane trapping standards (i.
