Native to China and Mongolia, the brown rat ( Rattus norvegicus ) now enjoys a worldwide distribution. While black rats house mouse tracked regional development of human agricultural settlements, did not appear in Europe until 1500s, suggesting their range expansion was response relatively recent increases global trade. We inferred phylogeography using 32 k SNPs, detected 13 evolutionary clusters within five routes. One cluster arose following southward into Southeast Asia. Three additional...

Abstract The ability of natural populations to adapt new environmental conditions is crucial for their survival and partly determined by the standing genetic variation in each population. Populations with higher diversity are more likely contain individuals that better adapted circumstances than lower diversity. Here, we use both neutral major histocompatibility complex (MHC) markers test whether small highly fragmented hold large ones. We black grouse as it distributed across Europe found...

We report the first detection of Seoul hantavirus (SEOV)-specific antibodies in wild brown rat population Netherlands. SEOV-reactive were found three rats out 16 a repeated series tests including immunofluorescence assay, immunoblot, and enzyme-linked immunosorbent assay. Focus reduction neutralization test confirmed presence SEOV-specific antibodies, reverse-transcription polymerase chain reaction (RT-PCR) hantaviral RNA. This discovery follows recent findings SEOV infections pet humans...

Abstract Wildfire is a highly variable natural phenomenon, yet despite this, climate change already making wildfire conditions measurably worse around the world; however, detailed knowledge about Aotearoa New Zealand's currently limited. This study blends weather observations with regional model projections to assess 21st‐century climate. We find that in 21st‐century, emergence of new—more severe will occur. Detailed analysis observed and simulated finds “very‐extreme” matching levels...

The MHC, which is regarded as the most polymorphic region in genomes of jawed vertebrates, plays a central role immune system by encoding various proteins involved response. chicken MHC-B genomic has highly streamlined gene content compared to mammalian MHCs. Its core includes genes Class I and IIB molecules but only ~92Kb length. Sequences other galliform MHCs show varying degrees similarity that chicken. black grouse (Tetrao tetrix) wild bird species an important model conservation...

An atmospheric tracer experiment using SF6 was designed to assess changes in the dispersive environment trunk space of a southern pine forest through four thinning regimes. Over 6000 mean half-hourly samples were collected and analyzed along with high-frequency time series concentration sampling at 1 Hz over course trials. The experimental plot thinned stages, from state dense boles thick understory, >32.1 m2 ha-1 (140 ft2 ac-1) basal area, final area 16.1 (70 understory removed. In this...

Gene duplications are frequently observed in the Major Histocompatibility Complex (MHC) of many species, and as a consequence loci belonging to same MHC class often too similar tell apart. In birds, single locus genotyping genes has proven difficult due concerted evolution homogenizing sequences at different loci. But studies on evolutionary history, mode selection heterozygosity correlations cannot be performed before it is possible analyse duplicated separately. this study we investigate...

Leptospirosis is an emerging zoonosis of global concern; however, its contemporary occurrence in Sweden, a European country partly located north the Arctic Circle, poorly known. Four out 30 brown rats, captured within urban districts were found to be positive for antibodies Leptospira interrogans serovar Icterohaemorrhagiae. This causes Weil's disease humans, severe infection with jaundice, renal failure, and hemorrhage. Our study first finding this highly pathogenic Swedish rats since 1930s.

Background: Snow leopards, Panthera uncia, are a threatened apex predator, scattered across the mountains of Central and South Asia. Disease threats to wild snow leopards have not been investigated.Methods Results: Between 2008 2015, twenty in Gobi desert Mongolia were captured immobilised for health screening radio-collaring. Blood samples external parasites collected pathogen analyses using enzyme-linked immunosorbent assay (ELISA), microscopic agglutination test (MAT), next-generation...

The Major Histocompatibility Complex (MHC) is a cluster of genes involved in the vertebrate immune system and includes loci with an extraordinary number alleles. Due to complex evolution MHC genes, alleles from different within same class can be very similar therefore difficult assign separate loci. Consequently, single locus amplification hard carry out species recently duplicated class, multiple have genotyped simultaneously. Since amplified length, accurate genotyping difficult. Reference...

Rat carcasses obtained from pest control interventions can potentially be used for an efficient surveillance of zoonotic diseases such as leptospirosis. To evaluate the performance different laboratory methods detection pathogenic Leptospira spp., heart and kidney samples wild Norway rats were analyzed by microscopic agglutination test (MAT, gold standard), a commercial IgG enzyme-linked immunosorbent assay, optimized quantitative PCR (secY qPCR, followed sequencing). We found secY qPCR to...

The alpine ecosystems and communities of central Asia are currently undergoing large-scale ecological socio-ecological changes likely to affect wildlife-livestock-human disease interactions zoonosis transmission risk. However, relatively little is known about the prevalence pathogens in this region.

The breeding consequences of virus infections have rarely been studied in avian natural populations. In this paper we investigated the links between humoral immunity following a flavivirus infection and reproduction wild bird population collared flycatcher (Ficedula albicollis). We analyzed plasma from 744 birds for antibodies correlated these results to number reproductive components.Nearly one third (27.8%) sampled flycatchers were found seropositive flavivirus. Males had significantly...

ABSTRACT Once restricted to northern China and Mongolia, the brown rat ( Rattus norvegicus ) now enjoys a worldwide distribution due evolution of commensalism with humans. In contrast black rats house mouse, which have tracked regional global development human agricultural settlements, do not appear in European historical record until 1500s, suggesting their range expansion was response relatively recent increases trade modern sea-faring. We inferred phylogeography using 32k SNPs reconstruct...
