Emys orbicularis is receding from Europe, mainly due to anthropogenic habitat changes. Its parasite, Placobdella costata, widely distributed within both the former and present distribution range of host. Though closely associated with mud turtle, it may have other hosts (birds, amphibians, reptiles). reproductive period coincides that its host's migration breeding grounds, thus facilitating dispersal parasite. Based on literature data we analyzed geographic spread P. costata turtle observe...
An epistemological-evolutionary conception of leeches (Hirudinida) based on features the female reproductive system in combination with other morphological characters is presented spirit cladistic school taxonomy. Characters relating to structure ovary and course oogenesis were interpreted this manner, for first time. Each study was conducted type species higher taxonomic groups true leeches. Results analyses using only as well show Piscicolidae Glossiphoniidae sister clades making...
Erpobdella borisi n. sp. is a predatory leech inhabiting cave waters in Iran. Probably, it either troglobiont or troglophile. The has no eyes, and the complete mid-body somite divided unequally into five annuli. Results of phylogenetic analysis based on morphological characters COI gene sequence indicate species to be closely related japonica, E. octoculata testacea.
Up to now in Tunisia, freshwater Hirudinida are represented by two mainly haematophagous families: Hirudinidae and Glossiphonidae, a predatory one: the family Erpobdellidae. The present study provides new information on diversity taxonomy of erpobdellid leeches. Identification was based, addition morphological data, length sperm ducts lengths ovisacs relation neurosomite (ns) shape size male atrium. Five taxons found. Two subspecies reported for first time country: Dina punctata Johansson,...
A new species of fish leech from England, Piscicola siddalli n. sp. (Piscicolidae), was collected in 2006 on stones and grayling (Thymmallus thymmallus L.) the River Ure, North Yorkshire, Great Britain. The is 4(12) annulate; gonopores are separated by four annuli. male gonopore much larger than female gonopore. Seminal receptacle consists a round aperture, located at distance 3 annuli behind Copulatory area clitellum form circle. Vector tissue has circular plate, below oviduct opening.
ABSTRACT Approximately 130 individuals of Acanthobdella peledina and 100 Paracanthobdella livanowi were studied. Morphometric measurements taken to explore the body form. The digestive reproductive systems leech‐like annelids analyzed for first time in such a high number specimens. Observation A. P. revealed crucial differences system taxa, mostly regarding variation shape testisacs length ovisacs. results analysis suggest that blood‐sucking parasites order Acanthobdellida may also lead...
The aim of this study was to confirm the taxonomic status Piscicola pojmanskae Bielecki, 1994 found on Salmonidae fish. fish leech identified based a diligent morphological analysis as well COI gene sequence (DNA barcoding). phylogenetic relationship with other piscicolid leeches analyzed well. various fins both graylings and resident form trouts. prevalence infection 1.63%. In paper, probable causes lack relation between number body length host-searching strategy used by P. are discussed.
Abstract Acanthobdellida gnaw into the sides of salmonid fishes in frigid Arctic lakes and rivers, latching on with fearsome facial hooks. Sister to leeches, they are an ancient lineage two described species. Unfortunately, rarely collected, leading a paucity literature despite their unique morphology. Populations range from Eurasia Alaska (USA), but few specimens Acanthobdella peledina represented molecular studies, no data exist for Paracanthobdella livanowi, making taxonomic position...
Abstract Hirudinida comprise a constant component of benthofauna in running waters and their taxonomic composition is often analyzed to evaluate the environmental quality. However, indicatory role particular species still arguable. Thus, it very important provide more detailed information on impact parameters structure within this group invertebrates. Representatives nine were found investigated upland stream including mainly Erpobdella vilnensis E. octoculata. The research has demonstrated...
This study presents the parasitic relationship between leech, Caspiobdella fadejewi, and juvenile Atlantic sturgeon, Acipenser oxyrinchus. The aim was to determine leech invasion intensity extensity describe parasite feeding location preferences on ventral side of snout gill cavities. prevalence C. fadejewi occurrence 37.3%, at an one eight leeches. It confirmed that positively correlated with sturgeon total length (r=0.545, P<0.05, N=15). host-searching mechanism is most probably based...
A new species of fish leech from Poland, Piscicola burresoni n. sp. (Piscicolidae), is described. The was found in 2007 on stones and pike (Esox lucius L.) chub (Leuciscus cephalus the Łyna River, Poland. small, relatively flattened, with a prominent coarctation between trachelosome urosome. pigmentation unique to it has 14 annuli gonopores separated by 4 annuli. receptaculum seminis consists an elliptical aperture located at distance 3 behind female gonopore. copulatory area clitellum...
Occurrence and breeding of Hirudo medicinalis were recorded in birds’ nests the fishing ponds water bodies used extensively by anglers south-eastern Poland, 4 11 studied bird species (Circus aeruginosus, Fulica atra, Cygnus olor, Chroicocephalus ridibundus). Factors important for distribution density this leech were: nest height, pH oxygen concentration inside nests, body-length nesting birds. Our data show that (1) H. chooses as habitats are safe rich predators (particularly fish) provide...
Abstract Specimens of Piscicola pojmanskae were identified in the macrozoobenthos community Zostera meadows Puck Bay. The presented paper is first report on observation this species Gulf Gdańsk (the southern Baltic Sea). Leeches are a rare component benthic fauna brackish water area.
AbstractThe bipolar distribution of fish leeches (Piscicolidae) has been considered and discussed by leech biologists for a long time. All cases putative ranges related taxa that occur in cold temperate waters both hemispheres are absent the tropics have morphology-based hypotheses. Here, we present, first time, an instance substantiated morphological molecular data. The latter include mitochondrial genes 12S rRNA, COI, ND1 tRNA Leu, nuclear 28S rRNA. A new genus species Antarctic...
Activities of nineteen hydrolases were measured in the digestive systems predatory and blood-feeding true leeches (Hirudinida) their closest relatives, Branchiobdellida Acanthobdellida. Hydrolase activities analyzed different parts systems: species-specific anterior part, i.e. jaws, pharynx or proboscis, crop intestine. The results obtained suggest that food digestion possible absorption predominate intestine most studied Hirudinida A. peledina, whereas B. astaci these processes take place...
