| the contamination of birds with organic pollutants in the lake baikal region. | lake baikal is considered to be the largest reservoir of fresh natural water in the world. nevertheless industrial enterprises on its banks as well as river effluents contaminate this unique basin. in the present study birds' eggs (15 species) collected in the baikal region (selenga river estuary) have been analysed. quantitative determination of more than 40 individual organic pollutants (polycyclic aromatic hydrocarbons, phenols, organochlorine compounds) has been carried out using gc-ms as an ... | 1998 | 9573629 |
| the life-cycle of petasiger islandicus kostadinova & skirnisson, 2007 (digenea: echinostomatidae) elucidated with the aid of molecular data. | the small planorbid snail gyraulus cf. laevis (alder) from lake mývatn in iceland was found to emit large-tailed cercariae with 19 collar spines, and three-spined sticklebacks gasterosteus aculeatus l. were infected with metacercariae of a species of petasiger dietz, 1909. comparative sequence analysis using nd1 mitochondrial dna sequences revealed that the rediae and cercariae are conspecific with p. islandicus kostadinova & skirnisson, 2007, recently described from an isolated population of th ... | 2012 | 22711507 |
| cestodes of the horned grebe podiceps auritus (l.) (aves: podicipedidae) from lake myvatn, iceland, with the description of confluaria islandica n. sp. (hymenolepididae). | three cestode species are recorded from podiceps auritus at lake myvatn, iceland: tatria minor kowalewski, 1904 (amabiliidae), confluaria furcifera (krabbe, 1869) and c. islandica n. sp. (hymenolepididae). c. islandica n. sp. is described on the basis of specimens reported by baer (1962) as 'hymenolepis capillaris (krabbe, 1869)' and newly-collected specimens. it is unique among confluaria spp. in having: a muscular, thick-walled genital atrium with its proximal end divided into male and female ... | 2008 | 18030602 |
| petasiger islandicus n. sp. (digenea: echinostomatidae) in the horned grebe podiceps auritus (l.) (aves: podicipedidae) from iceland. | petasiger islandicus n. sp. is described and figured from a demographically isolated population of the horned grebe podiceps auritus auritus (l.) in lake mývatn (iceland). this new species belongs to the group of species with 19 collar spines which possess a large elongate-oval cirrus-sac, well-developed pars prostatica and massive bulb-like cirrus. within this group, p. islandicus appears most similar to p. oschmarini kostadinova & gibson, 1998, a form with similar body dimensions described fro ... | 2007 | 17896189 |
| palaearctic species of the genus confluaria ablasov (cestoda, hymenolepididae): a redescription and synonymy of c. capillaris (rudolphi, 1810). | the types of confluaria capillaris (rudolphi, 1810) from podiceps auritus in (?) germany and the types of c. capillaroides (fuhrmann, 1906) from podiceps dominicus in brazil are redescribed. c. capillaroides is recognised as a junior synonym of c. capillaris (new synonymy). data on specimens of the same species from p. cristatus and p. grisegena in bulgaria are also presented. the previous records of the two nominal species are critically analysed in view of the present redescriptions. the host ... | 1999 | 10613530 |
