predicting west nile virus seroprevalence in wild birds in senegal.west nile fever epidemiology is complex, and the role of birds in the maintenance, amplification, and dissemination of the west nile virus (wnv) remains partially unknown. in 2003, a serological study was performed in senegal, where west nile infection is considered endemic. the goal was to identify potential reservoirs of wnv among bird species present in the ferlo area (northern senegal) and the senegal river valley, and to screen the ecological factors possibly related to west nile infection. ...200919196131
do highways influence density of land birds?/ land bird densities in roadside habitats were studied in 17 locations in central finland by the line transect method. two transects were censused in each location. the first transect was situated 25 m from highway edge and the second transect 200 m away from the first one. the results suggested that land bird density was lower closer to highways. species that avoided the road included willow warbler (phylloscopus trochilus), crossbills (loxia spp.), and tree pipit (anthus trivialis). the compo ...19989465138
polymorphism at the clock gene predicts phenology of long-distance migration in birds.dissecting phenotypic variance in life history traits into its genetic and environmental components is at the focus of evolutionary studies and of pivotal importance to identify the mechanisms and predict the consequences of human-driven environmental change. the timing of recurrent life history events (phenology) is under strong selection, but the study of the genes that control potential environmental canalization in phenological traits is at its infancy. candidate genes for circadian behaviou ...201525780812
[habitat selection and metapopulation structure: a multi-year study of distribution of the hodgson's pipit, anthus hodgsoni richm. (aves, passeriformes)].numbers and distribution of the hodgson's pipit (anthus hodgson richm.: aves, passeriformes) were studied in the yenissei middle taiga region over an area of about 450 sq km. distribution of breeding pairs was mapped on fixed study plots (up to 450 ha in total) annually during 15 years. habitat properties were described and measured in detail on 53 4-ha homogeneous plots within the area. it is shown by means of multiple regression, an average bird abundance over these plots depends on five habit ...200818956571
tick-borne pathogens in ticks collected from breeding and migratory birds in switzerland.from 2007 to 2010, 4558 migrating and breeding birds of 71 species were caught and examined for ticks in switzerland. a total of 1205 specimens were collected; all were ixodes ricinus ticks except one ixodes frontalis female, which was found on a common chaffinch (fringilla coelebs) for the first time in switzerland. each tick was analysed individually for the presence of borrelia spp., rickettsia spp., anaplasma phagocytophilum and tick-borne encephalitis virus (tbev). altogether, 11.4% of bird ...201425113989
surveillance of tick-borne encephalitis virus in wild birds and ticks in tomsk city and its suburbs (western siberia).to study the role of wild birds in the transmission of tick borne encephalitis virus (tbev), we investigated randomly captured wild birds bearing ixodid ticks in a very highly endemic tbe region located in tomsk city and its suburbs in the south of western siberia, russia. the 779 wild birds representing 60 species were captured carrying a total of 841 ticks, ixodes pavlovskyi pom., 1946 (n=531), ixodes persulcatus p. sch., 1930 (n=244), and ixodes plumbeus leach. 1815 (n=66). the highest averag ...201424380691
Impact of climate change on risk of incursion of Crimean-Congo haemorrhagic fever virus in livestock in Europe through migratory birds.Aims: To predict the risk of incursion of Crimean-Congo haemorrhagic fever virus (CCHFV) in livestock in Europe introduced through immature Hyalomma marginatum ticks on migratory birds under current conditions and in the decade 2075-2084 under a climate-change scenario. Methods and Results: A spatial risk map of Europe comprising 14 282 grid cells (25 × 25 km) was constructed using three data sources: (i) ranges and abundances of four species of bird which migrate from sub-Saharan Africa to Eu ...201122118269
borrelia burgdorferi sensu lato infection in passerine birds from the mazurian lake region (northeastern poland).the aim of the present study was to evaluate a potential role of different passerine birds species in mazurian lake region (northeast poland) in the spread of borrelia burgdorferi sensu lato, the spirochaete that causes lyme disease. a total number of 1254 birds (representing 42 species) were captured during the 3-year study period. blood samples were collected from birds and analyzed with a nested polymerase chain reaction technique in order to detect fragments of the pathogen dna. positive res ...200414681070
[new species of mites of the genus ptilonyssus (gamasina: rhinonyssidae) isolated from passeriformes (aves: passeriformes) from russia and neighboring countries].eight new species of the genus ptilonyssus (berl. et troues.) (gamasina: rhinonyssidae) from nasal cavities of the passeriformes from territory of the former ussr are described: p. ammomani sp. n. from ammomanus deserti (alaudidae) collected in turkmenistan; p. spini sp. n. from spinus spinus (fringillidae) of kaliningrad district (russia); p. ripariae sp. n. from riparia riparia (hirundinidae) and p. acanthopneustes sp. n. from phylloscopus borealis (sylviidae) collected in tjumen district (rus ...200312677669
