Lack of phenological shift leads to increased camouflage mismatch in mountain hares.

Proc Biol Sci 2020 12 16;287(1941):20201786. Epub 2020 Dec 16.

Wildlife Biology Program and Office of Research and Creative Scholarship, University of Montana, Missoula, MT 59812, USA.

Understanding whether organisms will be able to adapt to human-induced stressors currently endangering their existence is an urgent priority. Globally, multiple species moult from a dark summer to white winter coat to maintain camouflage against snowy landscapes. Decreasing snow cover duration owing to climate change is increasing mismatch in seasonal camouflage. Read More

Transcriptomic regulation of seasonal coat color change in hares.

Ecol Evol 2020 Feb 15;10(3):1180-1192. Epub 2020 Jan 15.

CIBIO Centro de Investigação em Biodiversidade e Recursos Genéticos InBIO Laboratório Associado Universidade do Porto Vairão Portugal.

Color molts from summer brown to winter white coats have evolved in several species to maintain camouflage year-round in environments with seasonal snow. Despite the eco-evolutionary relevance of this key phenological adaptation, its molecular regulation has only recently begun to be addressed. Here, we analyze skin transcription changes during the autumn molt of the mountain hare () and integrate the results with an established model of gene regulation across the spring molt of the closely related snowshoe hare ().

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.

Louping ill virus in the UK: a review of the hosts, transmission and ecological consequences of control.

Authors:
Lucy Gilbert

Exp Appl Acarol 2016 Mar 24;68(3):363-74. Epub 2015 Jul 24.

James Hutton Institute, Craigiebuckler, Aberdeen, AB15 8QH, UK.

Louping ill virus (LIV) is a tick-borne flavivirus that is part of the tick-borne encephalitis complex of viruses (TBEV) and has economic and welfare importance by causing illness and death in livestock, especially sheep, Ovies aries, and red grouse, Lagopus lagopus scoticus, an economically valuable gamebird. Unlike Western TBEV which is found primarily in woodlands and is reservoired by small rodents, LIV is not generally transmitted by small rodents but instead by sheep, red grouse and mountain hares and, therefore, is associated with upland heather moorland and rough grazing land. Red grouse are a particularly interesting transmission host because they may acquire most of their LIV infections through eating ticks rather than being bitten by ticks. Read More
