| dynamics in the evolution of sexual traits: losses and gains, radiation and convergence in yellow wagtails (motacilla flava). | we analyse patterns of genetic diversity and song complexity in the palaearctic yellow wagtail (motacilla flava), a highly polytypic species complex. mitochondrial and nuclear dna show that the complex is polyphyletic, despite parallel plumage variation in western and eastern clades. in the western clade there is genetic structure among southern subspecies, haplotype diversity decreases with latitude, and northern subspecies show evidence of bottlenecking and rapid expansions, as expected from i ... | 2003 | 12859633 |
| the bird species of kumasir lake (kahramanmaras-turkey) and a view of environmental ethics on sustainable wetland management. | kumasir lake is located next to towns of donuklu and fatih, nine km west of kahramanmaras city center the region of east mediterranean, turkey this lake is of crucial importance from the point of native and immigrant birds. we located 17 birdspecies in this area during our observations carried out in the spring and autumn of 2005-2006. these were ciconia ciconia l., anas platyrhynchos l., accipiter nisus l., accipiter brevipes l., fulica atra l., columba palumbus l., merops apiaster l., upupa ep ... | 2008 | 18972701 |
| first data on the genetic diversity of avian haemosporidians in china: cytochrome b lineages of the genera plasmodium and haemoproteus (haemosporida) from gansu province. | a total of 76 birds belonging to 23 species and 14 families was examined for the presence of plasmodium spp. and haemoproteus spp. birds were trapped at four localities in gansu province, china, in june-july 2011. dna was isolated from blood samples and parasite detection, and identification was based on pcr assays and sequences of 479 bp of cyt b gene. the total prevalence of haemosporidians was 21.0%. haemoproteus spp. were detected in 14 birds (prevalence 18.4%). the lineage cyapic1 from cyan ... | 2013 | 23851731 |
| a comparison of the blood parasites in three subspecies of the yellow wagtail motacilla flava. | one-hundred and eighty yellow wagtails motacilla flava belonging to 3 subspecies (motacilla flava feldegg, motacilla flava flava, motacilla flava thunbergi) were caught during the spring migration in south kazakhstan and investigated by microscopic examination of stained blood smears. haemoproteus anthi, haemoproteus motacillae, leucocytozoon fringillinarum, leucocytozoon majoris, plasmodium relictum, plasmodium polare, atoxoplasma sp., trypanosoma sp., and microfilariae were identified. the ove ... | 2001 | 11534666 |
| [bird trematodes of lower silesia. iv. specimens from the genus mosesia (pleurogenidae, trematoda)--new element of parasitic-fauna passeriform birds from lower silesia]. | illustrated descriptions of mosesia pavlovskii, m. sittae and m. microsoma have been presented. these species have been described for the first time in poland, and two of them--m. sittae and m. microsoma--have not been know in europe until now. motacilla flava, turdus philomelos and t. merula are new hosts of these trematodes. m. sittae has been recognized as an autochthonous species--completing its life cycle in the climatic conditions of lower silesia. as for the other two species, the author ... | 1993 | 8346659 |
| [new faunal and biological observations on ticks in abruzzo]. | ticks collected during the years 1975-76 in abruzzo (prov. l'aquila and chieti) italy are reported. the following species have been identified: ixodes canisuga, ixodes frontalis, ixodes hexagonus, ixodes ricinus, dermacentor marginatus, haemaphysalis sulcata, rhipicephalus bursa, rhipicephalus sanguineus, hyalomma marginatum. new hosts are: felis catus for ixodes canisuga; scolopax rusticola, motacilla flava, corvus cornix for ixodes frontalis; sciurus vulgaris for haemaphysalis punctata; garrul ... | 1976 | 1032325 |
| blood parasites, body condition, and wing length in two subspecies of yellow wagtail (motacilla flava) during migration. | blood parasites of migrating yellow wagtails of two subspecies--motacilla flava feldegg and motacilla flava flava-were studied on a sample of 473 birds caught in spring and autumn periods in bulgaria. we controlled eight "migration waves" (flocks captured in different evenings) of yellow wagtails for four parameters--average body mass, average fat level, average wing length, and average prevalence of different hematozoan species. gametocytes or meronts of a total of six species of hematozoa belo ... | 2012 | 22278726 |
| new records of nematodes of passerine migratory birds. | parasitological examination of three passerine bird species: the red-backed shrike lanius collurio, eurasian golden oriole oriolus oriolus and yellow wagtail motacilla flava, revealed the presence of the nematodes acuaria subula, diplotriaena ozouxi, viguiera euryoptera and microtetrameres inermis. all the birds were obtained in the spring (april-may); the nematodes found were mature, which indicates infection in the hosts' wintering grounds. the gizzard worm acuaria subula is a new record from ... | 2013 | 24881284 |
| the widespread biting midge culicoides impunctatus (ceratopogonidae) is susceptible to infection with numerous haemoproteus (haemoproteidae) species. | haemoproteus parasites are widespread, and some species cause disease in wild and domestic birds. however, the insect vectors remain unknown for the majority of species and genetic lineages of avian haemoproteus. this information is crucial for better understanding the biology of haemoproteids, the epidemiology of haemoproteosis, and the development of morphological characters of sporogonic stages in wildlife haemosporidian parasites. it remains unclear whether the specificity of haemoproteus pa ... | 2017 | 28841905 |
| alkhurma hemorrhagic fever virus rna in hyalomma rufipes ticks infesting migratory birds, europe and asia minor. | alkhurma hemorrhagic fever virus rna was detected in immature hyalomma rufipes ticks infesting northward migratory birds caught in the north mediterranean basin. this finding suggests a role for birds in the ecology of the alkhurma hemorrhagic fever virus and a potential mechanism for dissemination to novel regions. increased surveillance is warranted. | 2018 | 29664386 |
