| serologic survey of birds for west nile flavivirus in southern moravia (czech republic). | a serosurvey for west nile virus (wnv) was carried out in 54 domestic birds (geese and ducks bred on fishponds) and 391 wild birds representing 28 migratory and resident species, using a plaque-reduction neutralization microtest with vero cells and egyptian topotype eg-101 strain as test virus. the birds were sampled in the south-moravian fishpond ecosystem between 2004 and 2006. antibodies to wnv were not detected in domestic waterfowl, but 23 (5.9%) free-living birds of 10 species showed a pos ... | 2008 | 18454599 |
| identification of blood parasites in old world warbler species from the danube river delta. | warbler species of the families sylviidae and acrocephalidae occurring in the danube river delta are frequently exposed to blood-sucking arthropods that transmit avian blood parasites. we investigated infections by three genera of hemosporidian parasites in blood samples from six warbler species. altogether in 17 (32.6%) of 52 blood samples, a pcr product was amplified. the great reed warbler (acrocephalus arundinaceus) had the highest prevalence, with 63.6% (7/11) infected individuals, whereas ... | 2009 | 20095169 |
| egg phenotype differentiation in sympatric cuckoo cuculus canorus gentes. | the brood parasitic common cuckoo cuculus canorus consists of gentes, which typically parasitize only a single host species whose eggs they often mimic. where multiple cuckoo gentes co-exist in sympatry, we may expect variable but generally poorer mimicry because of host switches or inter-gens gene flow via males if these also contribute to egg phenotypes. here, we investigated egg trait differentiation and mimicry in three cuckoo gentes parasitizing great reed warblers acrocephalus arundinaceus ... | 2010 | 20345810 |
| ticks of the hyalomma marginatum complex transported by migratory birds into central europe. | hyalomma ticks are well-known vectors transmitting infectious agents, which can result in severe and potentially fatal diseases in humans. migratory birds may carry infected ticks over long distances. here, we report on records of ticks of the h. marginatum complex in birds from central europe during the spring migration in 2008-2012. a total of 1172 birds belonging to 32 species, 16 families, and 3 orders was examined for ticks. sixteen individuals of 6 passerine species were found to transport ... | 2014 | 24877976 |
| the complete mitochondrial genome of japanese marsh warbler, locustella pryeri. | we sequenced the complete mitochondrial genome of japanese marsh warbler (locustella pryeri) for the first time. the mitogenome was 17,968 bp in length, contained 13 protein-coding genes, 22 transfer rna genes, 2 ribosomal rna genes and 2 putative control regions. the total base composition of the mitogenome was 29.7% for a, 24.1% for t, 31.9% for c and 14.3% for g. the complete mitogenome sequence provides useful information for phylogenetic analyses among passeriformes and species conservation ... | 2016 | 24617481 |
| are cuckoos maximizing egg mimicry by selecting host individuals with better matching egg phenotypes? | avian brood parasites and their hosts are involved in complex offence-defense coevolutionary arms races. the most common pair of reciprocal adaptations in these systems is egg discrimination by hosts and egg mimicry by parasites. as mimicry improves, more advanced host adaptations evolve such as decreased intra- and increased interclutch variation in egg appearance to facilitate detection of parasitic eggs. as interclutch variation increases, parasites able to choose hosts matching best their ow ... | 2012 | 22384060 |
| [analyzing japanese marsh warbler (megalurus pryeri) song behavior in the breeding season]. | the songs of japanese marsh warblers (megalurus pryeri) were recorded during may to july in 2009 at shuangtaihekou nature reserve, liaoning, china. based on song characteristics, songs were divided into three types: courtship songs, alarm calls or contact calls. we analyzed and measured four parameters from 543 verses recorded from 20 males. the parameters were: duration of verse, number of syllables, duration of syllable, and interval of syllable. verses of courtship song are formed of two vers ... | 2011 | 21509959 |

| haematospirillum and insect wolbachia dna in avian blood. | in this study, blood samples of 259 acrocephalus sp. warblers were molecularly analysed for anaplasmataceae and rhodospirillaceae based on pcr amplification of 16s rrna gene fragments. one bird blood sample (from reed warbler, acrocephalus scirpaceus) yielded a sequence with 99.8% identity to haematospirillum jordaniae. this is the first molecular evidence for the occurrence of this species in the blood of any vertebrate other than human. another bird blood sample (from marsh warbler: acrocephal ... | 2017 | 29063344 |
| energy crops affecting farmland birds in central europe: insights from a miscanthus-dominated landscape. | the expansion of energy crops such as miscanthus miscanthus x giganteus has changed the habitat of european farmland birds. however, most studies on the subject are based in western europe. we surveyed the avian community in a sample bioenergy landscape in poland to investigate the pattern of use of the crop by birds in central europe. during a year-long survey, 80 species were noted, with 32 sighted in miscanthus. the number of bird sightings was negatively correlated with the area covered by m ... | 2019 | 30636777 |
