Fish leeches of Poland in relation to the Palaearctic piscicolines [Hirudinea: Piscicolidae: Piscicolinae]

Coexistence of Placobdella costata (Fr. Müller, 1846) (Hirudinida: Glossiphoniidae) and mud turtle Emys orbicularis
The geographic spread of P. costata and mud turtle and the associated leech species is analyzed to observe the possible overlap of their habitats and to characterize E. orbicularis characterized by greater length of the carapace and weight, compared with males and juvenile individuals.

The latest classification, known as the WISCI (Walking Index for Spinal Cord Injury) is described in detail, which is the most detailed scale that is also the most sensitive to changes in the patient's walking ability compared to the other scales.
Ovary architecture of two branchiobdellid species and Acanthobdella peledina (Annelida, Clitellata)
It is suggested that the formation of germ-line cysts and ovary meroism should be regarded as basal conditions for all Clitellata.

Results of phylogenetic analysis based on morphological characters and COI gene sequence indicate the species to be closely related to Erpobdella japonica, E. octoculata and E. testacea.
Glossiphoniidae Vaillant, 1850 (Hirudinea) of Poland--systematics and perspectives of studies.
A detailed study on the life cycles and variation of the Polish members of the Glossiphoniidae would provide new and valuable data and would allow at least for proposing a good, modern standard of species description without which a world-wide revision is hardly possible.
A systematic study on the complex species Erpobdella testacea [Savigny, 1820] [Hirudinea, Erpobdellidae]
Sperm Transfer Through the Vector Tissue in Piscicola Respirans (Clitellata, Hirudinea, Piscicolidae)
The ultrastructural pictures show that the long cytoplasmic processes of granular cells, which constitute the main mass of the vector tissue, are not engaged in sperm transport, and it is suggested that the sperm is pumped with a high pressure from the spermatophore into thevector tissue, and as a result the vectors cells are pushed aside and spermatozoa can freely pass between them.
Biological diversity of leeches (Clitellata: Hirudinida) based on characteristics of the karyotype.
The phylogeny scheme of leeches proposed by Mann shows the Glossiphoniidae as primitive to the Piscicolidae, and Hirudinidae as giving rise to the Haemopidae and Erpobdellidae, and the diploid number of 16 was suggested to be a primitive value.

A key for the determination of freshwater erpobdellid species from Tunisia is proposed and a comprehensive comparison of the three genera is presented.
