trypanosoma avium of raptors (falconiformes): phylogeny and identification of vectors.avian trypanosomes are widespread parasites of birds, the transmission of which remains mostly unclear, with various blood-sucking insects mentioned as possible vectors. a search for vectors of trypanosomes of sparrowhawk (accipiter nisus), buzzard (buteo buteo), lesser-spotted eagle (aquila pomarina) and kestrel (falco tinnunculus) was performed in czech and slovak republics. black flies (eusimulium spp.), hippoboscid flies (ornithomyia avicularia), mosquitoes (culex pipiens pipiens) and biting ...200212358422
a snapshot avian surveillance reveals west nile virus and evidence of wild birds participating in toscana virus circulation.birds are involved in the epidemiology of several vector-borne viruses, as amplification hosts for viruses, dissemination vehicles for the vectors, and sources of emerging strains in cross-species transmission. turkey provides diverse habitats for a variety of wild birds and is located along major bird migration routes. this study was undertaken to provide a cross-sectional screening of avian specimens for a spectrum of vector-borne viruses.201728832259

animals as an indicator of carbon sequestration and valuable landscapes.possibilities of the assessment of a landscape with the use of succession development stages, monitored with the value of the mean individual biomass (mib) of carabid beetles and the occurrence of bird species are discussed on the basis of an example from poland. higher variability of the mib value in space signifies a greater biodiversity. apart from the variability of mib, it is suggested to adopt the occurrence of the following animals as indicators, (in the order of importance), representing ...201121738434
central european strigeidae railliet, 1919 (trematoda: strigeidida): molecular and comparative morphological analysis suggests the reclassification of parastrigea robusta szidat, 1928 into strigea abildgaard, 1790.strigeidae railliet, 1919 are digenean parasites of birds and mammals that are characteristic by their cup-shaped forebody and bilobed holdfast organ. despite that the family is taxonomically unsettled, particularly due to a very limited number of visible autapomorphic identification features, molecular phylogenetics have never been applied to analyze the relationships among european members of strigeidae except for the genus ichthyocotylurus. here, we analyze the strigeidae found during the exa ...201830003965
orientation of native versus translocated juvenile lesser spotted eagles (clanga pomarina) on the first autumn migration.the ontogeny of migration routines used by wild birds remains unresolved. here we investigated the migratory orientation of juvenile lesser spotted eagles (lse; clanga pomarina) based on translocation and satellite tracking. between 2004 and 2016, 85 second-hatched juveniles (abels) were reared in captivity for release into the declining german population, including 50 birds that were translocated 940 km from latvia. in 2009, we tracked 12 translocated juveniles, as well as eight native juvenile ...201728768749
genetic determination of migration strategies in large soaring birds: evidence from hybrid eagles.the relative contributions of genetic and social factors in shaping the living world are a crucial question in ecology. the annual migration of birds to their wintering grounds and back provides significant knowledge in this field of research. migratory movements are predominantly genetically determined in passerine birds, while in large soaring birds, it is presumed that social (cultural) factors play the largest role. in this study, we show that genetic factors in soaring birds are more import ...201830111595

evaluating the connectivity of a protected areas' network under the prism of global change: the efficiency of the european natura 2000 network for four birds of prey.climate and land use changes are major threats to biodiversity. to preserve biodiversity, networks of protected areas have been established worldwide, like the natura 2000 network across the european union (eu). currently, this reserve network consists of more than 26000 sites covering more than 17% of eu terrestrial territory. its efficiency to mitigate the detrimental effects of land use and climate change remains an open research question. here, we examined the potential current and future ge ...201323527237
bird diversity and distribution in relation to urban landscape types in northern rwanda.using the point count method, linear mixed models, shannon's diversity index, and bray-curtis cluster analysis, we conducted a study of the effect of urban fabric layout on bird diversity and distribution in northern rwanda. the results showed a significant effect of city landscapes on bird richness and relative abundance; residential neighborhoods, institutional grounds, and informal settlements had the highest species diversity in comparison to other microlandscape types. riversides were chara ...201425133203
a multi-gene phylogeny of aquiline eagles (aves: accipitriformes) reveals extensive paraphyly at the genus level.the phylogeny of the tribe aquilini (eagles with fully feathered tarsi) was investigated using 4.2 kb of dna sequence of one mitochondrial (cyt b) and three nuclear loci (rag-1 coding region, ldh intron 3, and adenylate-kinase intron 5). phylogenetic signal was highly congruent and complementary between mtdna and nuclear genes. in addition to single-nucleotide variation, shared deletions in nuclear introns supported one basal and two peripheral clades within the aquilini. monophyly of the aquili ...200515737588
sex- and species-biased gene flow in a spotted eagle hybrid zone.recent theoretical and empirical work points toward a significant role for sex-chromosome linked genes in the evolution of traits that induce reproductive isolation and for traits that evolve under influence of sexual selection. empirical studies including recently diverged (pleistocene), short-lived avian species pairs with short generation times have found that introgression occurs on the autosomes but not on the z-chromosome. here we study genetic differentiation and gene flow in the long-liv ...201121492478
alterations in the breeding habitats for two endangered raptor species along the sava river basin, croatia.changes in habitat suitable for breeding of two sympatric raptor species (haliaeetus albicilla and aquila pomarina) were analysed along one of the most important breeding sites in croatia for both species. the habitat suitability modelling was used to assess the influence of forestry practice during 2000-2006 using the known data on nesting places along research area. the four most important variables for lesser spotted eagle were elevation, distance from the nearest pasture, vertical distance t ...201221800060
