| can parasites drive population cycles in mountain hares? | understanding the drivers of population fluctuations is a central goal of ecology. although well-established theory suggests that parasites can drive cyclic population fluctuations in their hosts, field evidence is lacking. theory predicts that a parasite that loosely aggregates in the host population and has stronger impact on host fecundity than survival should induce cycling. the helminth trichostrongylus retortaeformis in the uk's only native lagomorph, the mountain hare, has exactly these p ... | 2009 | 19203927 |
| dynamics of range margins for metapopulations under climate change. | we link spatially explicit climate change predictions to a dynamic metapopulation model. predictions of species' responses to climate change, incorporating metapopulation dynamics and elements of dispersal, allow us to explore the range margin dynamics for two lagomorphs of conservation concern. although the lagomorphs have very different distribution patterns, shifts at the edge of the range were more pronounced than shifts in the overall metapopulation. for romerolagus diazi (volcano rabbit), ... | 2009 | 19324811 |
| altitudinal patterns of tick and host abundance: a potential role for climate change in regulating tick-borne diseases? | the impact of climate change on vector-borne infectious diseases is currently controversial. in europe the primary arthropod vectors of zoonotic diseases are ticks, which transmit borrelia burgdorferi sensu lato (the agent of lyme disease), tick-borne encephalitis virus and louping ill virus between humans, livestock and wildlife. ixodes ricinus ticks and reported tick-borne disease cases are currently increasing in the uk. theories for this include climate change and increasing host abundance. ... | 2010 | 19685082 |
| risk indicators for the tick ixodes ricinus and borrelia burgdorferi sensu lato in sweden. | the distributional area of the tick ixodes ricinus (l.), the primary european vector to humans of lyme borreliosis spirochaetes (borrelia burgdorferi sensu lato) and tick-borne encephalitis virus, appears to be increasing in sweden. it is therefore important to determine which environmental factors are most useful to assess risk of human exposure to this tick and its associated pathogens. the geographical distribution of i. ricinus in sweden was analysed with respect to vegetation zones and clim ... | 2009 | 19712153 |
| top predators, mesopredators and their prey: interference ecosystems along bioclimatic productivity gradients. | 1. the mesopredator release hypothesis (mrh) suggests that top predator suppression of mesopredators is a key ecosystem function with cascading impacts on herbivore prey, but it remains to be shown that this top-down cascade impacts the large-scale structure of ecosystems. 2. the exploitation ecosystems hypothesis (eeh) predicts that regional ecosystem structures are determined by top-down exploitation and bottom-up productivity. in contrast to mrh, eeh assumes that interference among predators ... | 2010 | 20337755 |
| natural toxoplasma gondii infections in european brown hares and mountain hares in finland: proportional mortality rate, antibody prevalence, and genetic characterization. | in material examined postmortem in finland from may 2006 to april 2009, acute generalized toxoplasmosis was the immunohistochemically confirmed cause of death in 14 (8.1%) of 173 european brown hares (lepus europaeus) and four (2.7%) of 148 mountain hares (lepus timidus). sera from 116 of the european brown hares and 99 of the mountain hares were screened with a commercial direct agglutination test for toxoplasma gondii-specific igg antibodies at a dilution of 1:40. all sera from cases of fatal ... | 2011 | 21270004 |
| borrelia burgdorferi sensu lato detected in skin of norwegian mountain hares (lepus timidus) without signs of dissemination. | the mountain hare (lepus timidus) population in southern norway appears to be in decline. necropsy and laboratory examinations of 36 hares found dead or diseased during 2007-2009 in vest- and aust-agder counties showed that disease and deaths were attributed to multiple causes, with no specific etiology emerging as a cause for population decline. to investigate whether borrelia burgdorferi sensu lato (s.l.) infection is associated with mortality in mountain hares, tissues and ticks collected fro ... | 2011 | 21441181 |
| reconstruction of karyotype evolution in core glires. i. the genome homology revealed by comparative chromosome painting. | glires represent a eutherian clade consisting of rodents and lagomorphs (hares, rabbits, and pikas). chromosome evolution of glires is known to have variable rates in different groups: from slowly evolving lagomorphs and squirrels to extremely rapidly evolving muroids. previous interordinal homology maps between slowly evolving glires were based on comparison with humans. here, we used sets of chromosome-specific probes from tamias sibiricus (sciuridae), castor fiber (castoridae) and humans to s ... | 2011 | 21559983 |
| sexing european rabbits (oryctolagus cuniculus), european brown hares (lepus europaeus) and mountain hares (lepus timidus) with zfx and zfy loci. | we describe a new method for the sex determination of tissue originating from oryctolagus cuniculus (european rabbit), lepus europaeus (european brown hare) and lepus timidus (mountain hare) based on pcr-rflp analysis of point mutations that differentiate the zfx and zfy gene sequences. among several applications, this pcr-rflp method could be used to investigate gender ratio and evaluate the population dynamics of these species using samples collected when sex cannot be identified. | 2008 | 21586025 |
| the importance of willow thickets for ptarmigan and hares in shrub tundra: the more the better? | in patchy habitats, the relationship between animal abundance and cover of a preferred habitat may change with the availability of that habitat, resulting in a functional response in habitat use. here, we investigate the relationship of two specialized herbivores, willow ptarmigan (lagopus lagopus) and mountain hare (lepus timidus), to willows (salix spp.) in three regions of the shrub tundra zone-northern norway, northern european russia and western siberia. shrub tundra is a naturally patchy h ... | 2011 | 21833646 |
| first evidence of established populations of the taiga tick ixodes persulcatus (acari: ixodidae) in sweden. | the tick species ixodes ricinus and i. persulcatus are of exceptional medical importance in the western and eastern parts, respectively, of the palaearctic region. in russia and finland the range of i. persulcatus has recently increased. in finland the first records of i. persulcatus are from 2004. the apparent expansion of its range in finland prompted us to investigate if i. persulcatus also occurs in sweden. | 2016 | 27370406 |
| molecular evolution and antigenic variation of european brown hare syndrome virus (ebhsv). | european brown hare syndrome virus (ebhsv) is the aetiological agent of european brown hare syndrome (ebhs), a disease affecting lepus europaeus and lepus timidus first diagnosed in sweden in 1980. to characterize ebhsv evolution we studied hare samples collected in sweden between 1982 and 2008. our molecular clock dating is compatible with ebhsv emergence in the 1970s. phylogenetic analysis revealed two lineages: group a persisted until 1989 when it apparently suffered extinction; group b emerg ... | 2014 | 25155199 |
| complete coding sequences of european brown hare syndrome virus (ebhsv) strains isolated in 1982 in sweden. | european brown hare syndrome (ebhs) is characterised by high mortality of european brown hares (lepus europaeus) and mountain hares (lepus timidus). european brown hare syndrome virus (ebhsv) and the closely related rabbit haemorrhagic disease virus (rhdv) comprise the genus lagovirus, family caliciviridae. in contrast to rhdv, which is well studied, with more than 30 complete genome sequences available, the only complete genome sequence available for ebhsv was obtained from a strain isolated in ... | 2013 | 23640583 |
| tularaemia in norwegian dogs. | we describe tularaemia in a norwegian dog caused by francisella tularensis subspecies holarctica. a hamilton hound and his owner developed tulaeremia after hunting an infected mountain hare (lepus timidus). the dog showed signs of lethargy, anorexia and fever during a period two to four days after hunting and thereafter fully recovered. its antibody titers increased 32-fold from one to three weeks post exposure. thereafter, the titer declined and leveled off at moderate positive values up to one ... | 2014 | 25150161 |
| cycles in voles and small game in relation to variations in plant production indices in northern sweden. | population dynamics for voles (cricetidae), tengmalm's owl (aegolius funereus (l.)), red fox (vulpes vulpes (l.)) willow grouse (lagopus lagopus (l.)), black grouse (lyrurus tetrix (l.)), capercaillie (tetrao urogallus l.), hazel hen (tetrastes bonasia (l.)), mountain hare (lepus timidus l.) and tularemia (francisella tularensis (mccoy & chapin)) and game bird recruitment were studied by index methods in northern sweden. in addition contemporary temperature records and spruce (picea abies (l.) k ... | 1986 | 28311702 |
| biochemical genetic relationships among tunisian hares (lepus sp.), south african cape hares (l. capensis), and european brown hares (l. europaeus). | tunisian hares (n = 45), currently assigned to lepus capensis, were assayed for allelic variation at 40 allozyme loci, and allele frequencies at 32 loci were directly compared with earlier data of south african cape hares (l. capensis, n = 9) and european brown hares (l. europaeus, n = 244) to reveal genetic relationships among them. european mountain hares (l. timidus, n = 200) were used for outgroup comparison. in the tunisian hares 27.5% of the loci were polymorphic with 2-4 alleles. among al ... | 2005 | 16382363 |
| synchronous population fluctuations in voles, small game, owls, and tularemia in northern sweden. | 1. the population fluctuations in time in northern sweden are examined for the following species: voles, mountain hare, willow grouse, black grouse, capercaillie, hazel hen, red fox, long-eared owl, tengmalm's owl, and tularemia. necessary population data have been obtained from the period 1963-1975/76 as revealed by catches, literature survey, hunting statistics, bird ringing, and obligatory reporting of tularemia in man. 2. the populations of the species under consideration are found to fluctu ... | 1978 | 28309394 |
| mountain hare populations on islands: effects of predation by red fox. | on islands off the west coast of sweden the density of mountain hares (lepus timidus l.) is very high. one of the main predators on hares, the red fox (vulpes vulpes l.), is only present during short periods. data on hare density and predation by red fox and eagle owl (bubo bubo (l.)) has been analyzed from five islands over several years. winter mortality in years with low predation pressure was independent of hare density. but when red fox or eagle owl were present on islands (i.e., high preda ... | 1989 | 28311185 |
| the effects of low levels of pollutants on the reproduction of golden eagles in western norway. | the reproductive success of golden eagles was studied in an area in western norway between 62 degrees and 63 degrees n between 1973 and 1999. addled eggs were collected for analysis of chemical pollutants from nine territories; five from coastal areas and four from inland. the coastal sites had lower annual reproductive output than inland sites, and the eggs had a higher content of organochlorine compounds. there were relatively strong negative correlations between reproductive output and (1) sh ... | 2001 | 11556115 |
| assessment of the gastrointestinal helminth fauna of mountain hares (lepus timidus varronis) from the northwestern italian alps, with new records of parasite occurrence. | we describe the gastrointestinal parasite community of lepus timidus varronis, a subspecies of the mountain hare (l. timidus) living in the alps. two nematode species are reported for the first time in l. timidus. | 2014 | 24484488 |
| lead exposure of small herbivorous vertebrates from atmospheric pollution. | concentrations of pb in livers of willow grouse (lagopus lagopus), black grouse (tetrao tetrix), and hare (lepus timidus) were determined in samples collected during the period 1990-92 from 77 locations distributed across norway. our objective was to elucidate the impact of long-range atmospheric transport on the pb exposure of the animals. the moss hylocomium splendens was measured for atmospheric pb deposition and pb in soil at 60-cm depth was determined to reflect the natural geochemical back ... | 2000 | 15093005 |
| a phantom extinction? new insights into extinction dynamics of the don-hare lepus tanaiticus. | the pleistocene to holocene transition was accompanied by a worldwide extinction event affecting numerous mammalian species. several species such as the woolly mammoth and the giant deer survived this extinction wave, only to go extinct a few thousand years later during the holocene. another example for such a holocene extinction is the don-hare, lepus tanaiticus, which inhabited the russian plains during the late glacial. after being slowly replaced by the extant mountain hare (lepus timidus), ... | 2010 | 20695962 |

| seasonal and diel activity patterns of eight sympatric mammals in northern japan revealed by an intensive camera-trap survey. | the activity patterns of mammals are generally categorized as nocturnal, diurnal, crepuscular (active at twilight), and cathemeral (active throughout the day). these patterns are highly variable across regions and seasons even within the same species. however, quantitative data is still lacking, particularly for sympatric species. we monitored the seasonal and diel activity patterns of terrestrial mammals in hokkaido, japan. through an intensive camera-trap survey a total of 13,279 capture event ... | 2016 | 27732611 |
| numerical responses by populations of red fox and mountain hare during an outbreak of sarcoptic mange. | during a severe outbreak of sarcoptic mange (sarcoptes scabiei vulpes) starting among red foxes (vulpes vulpes) in sweden in the 1970s, we studied: 1) the establishment and spread of the disease in northernmost sweden (by inquiries), and 2) the 1970-84 bag records for foxes and mountain hares (lepus timidus) (an alternative prey to the fox's main prey, voles). since the first case of sarcoptic mange in 1975 the disease spread rapidly, with >50% of the hunting organizations having reported the di ... | 1987 | 28311970 |
| the effects of acaricide treatment of sheep on red grouse lagopus lagopus scotica tick burdens and productivity in a multi-host system. | ixodes ricinus (ixodida: ixodidae) ticks are of economic and pathogenic importance across europe. within the uplands of the u.k., management to reduce ticks is undertaken to benefit red grouse lagopus lagopus scotica (galliformes: phasianidae). management strategies focus on the acaricide treatment of domestic sheep ovis aries (artiodactyla: bovidae), but the effectiveness of this is less certain in the presence of wild hosts, particularly red deer cervus elaphus (artiodactyla: cervidae) and mou ... | 2017 | 29194726 |
| widespread introgression of mountain hare genes into fennoscandian brown hare populations. | 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 i ... | 2018 | 29370301 |
| tularaemia in european brown hares (lepus europaeus) and mountain hares (lepus timidus) characterized by histopathology and immunohistochemistry: organ lesions and suggestions of routes of infection and shedding. | tularaemia is an emerging zoonotic infectious disease caused by the bacterium francisella tularensis. in sweden, hares are considered to be key species in the epidemiology of tularaemia. the aim of this study was to characterize the pathology of natural tularaemia infection in european brown hares (ebhs) (lepus europaeus) and mountain hares (mhs) (lepus timidus) in sweden, in order to better understand the presentation of disease and the routes of infection, body dissemination and shedding of f. ... | 2017 | 28942292 |
| [the effect of coprophagy on the size of plant fibers in the digestive tract of hares lepus europaeus and l. timidus (lagomorpha, leporidae)]. | we have studied the distribution of plant fibers of different sizes in the digestive tracts of two hare species: the brown hare (lepus euopaeus) and the mountain hare (l. timidus). in all studied hares (18 specimens), the highest amount of fine-sized fibers (less than 0.25 mm length) was observed in the cecum (50-70% of the total fiber mass). it was found out that the fine-sized content in the digestive tract, and especially in the cecum, is provided not only by the separation mechanism of the c ... | 2017 | 26638238 |
| introgression of mountain hare (lepus timidus) mitochondrial dna into wild brown hares (lepus europaeus) in denmark. | in europe the mountain hare (lepus timidus) exists in great britain, norway, sweden, finland, parts of the alps and in eastern europe, but not in denmark. interspecific hybridization has been demonstrated between native swedish mountain hares and introduced brown hares (lepus europaeus). during the data collection in a study concerning danish brown hares we identified 16 hares with a single very divergent haplotype. | 2006 | 17105672 |
| studies on an idiopathic syndrome in the brown hare (lepus europaeus p.) and mountain hare (lepus timidus l.) in sweden, with special reference to hepatic lesions. | at routine post mortem examinations performed at the national veterinary institute (nvi), uppsala, sweden, during november 1983-may 1984, a syndrome principally characterized by an acute hepatosis was found in 85 out of 177 brown hares (lepus europaeus p.). the hepatic lesions consisted of periportal or extensive necrosis and haemorrhages. concomitant changes in other organs were tubular necrosis in the kidneys, acute catarrhal enteritis, severe congestion, oedema and haemorrhages of the lungs, ... | 1989 | 2515697 |

| phenolic compounds of willow bark as deterrents against feeding by mountain hare. | overwintering mountain hares (lepus timidus) fed selectively on the shoots of a number of northern willow (salix spp.) species. the hares preferred certain species over others and mature shoots over juvenile ones. there was a negative correlation between the phenolic glycoside concentration in the twigs and the hares' feeding. this correlation was substantiated by feeding experiments in which oat grains treated with purified phenoglycoside and catechin fractions of willow bark were offered along ... | 1985 | 28310435 |
| ancient colonization and within-island vicariance revealed by mitochondrial dna phylogeography of the mountain hare (lepus timidus) in hokkaido, japan. | we examined the phylogenetic status and history of the mountain hare lepus timidus in and around hokkaido using mitochondrial cytochrome b (cyt b) sequences from 158 samples from hokkaido and 14 from sakhalin, as well as four samples from the korean hare, l. coreanus. the phylogenetic analysis of the cyt b sequences generated in this study and obtained from dna databases showed the clear genetic specificity of the hokkaido lineage as a clade. the hokkaido lineage was estimated to have diverged f ... | 2012 | 23106564 |
| mountain hare transcriptome and diagnostic markers as resources to monitor hybridization with european hares. | we report the first mountain hare (lepus timidus) transcriptome, produced by de novo assembly of rna-sequencing reads. data were obtained from eight specimens sampled in two localities, alps and ireland. the mountain hare tends to be replaced by the invading european hare (lepus europaeus) in their numerous contact zones where the species hybridize, which affects their gene pool to a yet unquantified degree. we characterize and annotate the mountain hare transcriptome, detect polymorphism in the ... | 2017 | 29206218 |
| home-loving boreal hare mitochondria survived several invasions in iberia: the relative roles of recurrent hybridisation and allele surfing. | genetic introgression from a resident species into an invading close relative can result from repeated hybridisation along the invasion front and/or allele surfing on the expansion wave. cases where the phenomenon is massive and systematic, such as for hares (genus lepus) in iberia, would be best explained by recurrent hybridisation but this is difficult to prove because the donor populations are generally extinct. in the pyrenean foothills, lepus europaeus presumably replaced lepus granatensis ... | 2014 | 24149657 |
| louping ill virus in the uk: a review of the hosts, transmission and ecological consequences of control. | 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 mounta ... | 2016 | 26205612 |
| territory occupancy rate of goshawk and gyrfalcon: no evidence of delayed numerical response to grouse numbers. | two recent studies on territory occupancy rates of goshawk accipiter gentilis and gyrfalcon falco rusticolus report a 2-3-year-delayed numerical response to grouse numbers, which is a requirement for a hypothesis of predator-generated grouse cycles. the time lags were assumed to reflect the average age of sexual maturity in the raptor species. in southern norway, however, subadult (two-year-old) goshawk hens occupied only 18-25% of territories where occupancy was not recorded in the preceding ye ... | 2007 | 17549523 |
| changes in diet and morphology of finnish goshawks from 1960s to 1990s. | we studied the morphology of the goshawk in northern finland by measuring skin and skeletal characters of 258 museum specimens dated between 1961 and 1997. we predicted a decrease in the size of male goshawks from the 1960s because availability of their main prey, grouse, has decreased since then and grouse have been replaced in the diet by smaller prey during the breeding season. based on the assumption that winter is the most critical period for females, we predicted that female size should ha ... | 1999 | 28308326 |
