chewing lice of genus ricinus (phthiraptera, ricinidae) deposited at the zoological institute of the russian academy of sciences, saint petersburg, russia, with description of a new species.we revised a collection of chewing lice deposited at the zoological institute of the russian academy of sciences, saint petersburg, russia. we studied 60 slides with 107 specimens of 10 species of the genus ricinus (de geer, 1778). the collection includes lectotype specimens of ricinus ivanovi blagoveshtchensky, 1951 and of ricinus tugarinovi blagoveshtchensky, 1951. we registered ricinus elongatus olfers, 1816 ex turdus ruficollis, r. ivanovi ex leucosticte tephrocotis and ricinus serratus (dur ...201626902646
the genus biuterina fuhrmann, 1902 (cestoda, paruterinidae) in the old world: redescriptions of three species from palaearctic passeriformes.the syntypes of biuterina passerina fuhrmann, 1908 from alauda arvensis and galerida cristata (passeriformes, alaudidae) from an unknown locality are redescribed. b. fuhrmanni schmelz, 1941 is redescribed on the basis of its syntypes from emberiza aureola from china; its type-material contains, in addition to a scolex and pre-gravid and gravid fragments of biuterina, fragments of mature proglottides from a dilepidid cestode, which were erroneously used in the original description. specimens, whi ...200414739677
molecular detection of neospora caninum from naturally infected four passeriforme birds in china.neospora caninum is an intracellular protozoan infecting many domestic and wild animals. in the present study, the brain tissues of wild birds collected in hunan province of china were examined by n. caninum specific nested pcr, targeting the nc-5 gene and the internal transcribed spacer 1 (its-1) region of the nuclear ribosomal dna. the prevalence of n. caninum was detected in 15.5% (37/239) of wild birds, including 20.5% (9/44) of the examined olive-backed pipit anthus hodgsoni, 18.3% (24/131) ...201931173736
molecular prevalence and genetic characterization of toxoplasma gondii in wild birds in hunan province, china.toxoplasma gondii is a ubiquitous apicomplexan parasite of warm-blooded animals and humans. however, limited information is available about t. gondii infection in wild birds. in this study, 239 wild birds were collected from hunan province of china, including 38 chestnut bunting, 44 olive-backed pipit, 26 yellow-breasted bunting, and 131 tree sparrows. genomic dna of brain tissues were extracted and assayed by b1 gene, and the positive samples were genotyped at 10 genetic markers [sag1, sag2 (5' ...201930540544

[acoustic image of yellow-breasted bunting emberiza aureola pall].sonographic analysis of conspecific advertisement calls of yellow-breasted bunting (emberiza aureola) was carried out. calls of nine individuals living in the same range were compared. particular elements responsible for individual differences were recognized in the calls. at the same time, the elements defining conspecific characters were recognized in all individuals. individual differences were based on temporal indices: durations of individual syllables and intervals and even fusion of two s ...201616240753
mitochondrial genome of the emberiza aureola (emberizidae: emberiza).the emberiza aureola (yellow-breasted bunting), vulnerable (iucn), is a eurasian bird with very wide geographical range. the complete mitochondrial genome of e. aureola (16,800 bp in length) contained 37 genes (13 protein-coding genes, 2 rrna genes, and 22 trna genes) and a non-coding region (d-loop), which is similar to the typical mtdna of vertebrates. all the protein-coding genes in e. aureola were distributed on the h-strand, except for the nd6 subunit gene and ten trna genes which were enco ...201523901929
photoperiodic regulation of seasonal reproduction, molt and body weight in the migratory male yellow-breasted bunting (emberiza aureola).photoperiod has been shown to be a major source of temporal information regulating reproduction and associated functions in a number of avian species. we studied seasonal cycles of testicular volume, molt and body weight in natural and temperature-controlled conditions and under different artificial photoperiods in the yellow-breasted buntings. buntings posses seasonal cycles of testicular volume, molt, body weight and fattening with no major difference between natural and temperature-controlled ...201323910635
a comparative study on photoperiodic control of seasonal cycles in the females of migratory yellow breasted bunting and the resident tree sparrow.we studied the detailed pattern of seasonality in reproduction and the associated functions in the females of migratory yellow breasted bunting (emberiza aureola) and resident tree sparrow (passer montanus) under natural and artificial photoperiods. they exhibited seasonal cycles of ovarian development, moult and bill colour under natural photoperiods which were found linked to the annual solar cycle. photosensitive birds of both the species, when exposed to 9l/15d, 12l/12d and 14l/10d for 18 mo ...201425246220
global population collapse in a superabundant migratory bird and illegal trapping in china.persecution and overexploitation by humans are major causes of species extinctions. rare species, often confined to small geographic ranges, are usually at highest risk, whereas extinctions of superabundant species with very large ranges are rare. the yellow-breasted bunting (emberiza aureola) used to be one of the most abundant songbirds of the palearctic, with a very large breeding range stretching from scandinavia to the russian far east. anecdotal information about rapid population declines ...201526059233
