Examination of 10 bird species of the family Charadriidae have revealed the following nematode species: Strongyloides turkmenicus, Syngamus palustris, S. trachea, Porrocaecum semiteres, Tetrameres dubia, Eucoleus contortus and Capillaria sp. Three of them: S. turkmenicus, S. palustris and T. dubia parasitizing those hosts were found the first time in Czechoslovakia. Tringa glareola was found a new host for S. palustris.

According to current phylogenetic hypotheses, the bats of the families Rhinolophidae and Hipposideridae are sister groups nested within the clade of Pteropodiformes. A conservative nature of karyotypic evolution was previously reported within the two families. Karyotypes with diploid number (2n) varying between 58 and 62 chromosomes were assumed to prevail among the rhinolophid species, whereas, karyotypes with 32 chromosomes were found in most of the hipposiderid bats. However, divergent lower or higher 2n numbers have been recorded in some species in both families. Variation is documented in the present paper by examination of non-differentially stained karyotypes in 10 species belonging to genera Rhinolophus and Hipposideros from western Africa and southern India. Among the species studied, the karyotypes with a 2n of 32, 36, 52, 56, 58, and 62, and with relatively stable number of autosomal arms (FNa = 60, 62, 64) were recorded.

Four new species of the feather mite subfamily Pterodectinae (Proctophyllodidae) are described from passerine birds examined in Senegal: Dolichodectes gymnoris sp. nov. from the Russet-browed Bush-sparrow Gymnoris dentata (Sundevall, 1850) (Passeridae), Montesauria plocei sp. nov. from the Village Weaver Ploceus cucullatus (Muller, 1776) (Ploceidae), M. zosteropis sp. nov. from the African Yellow White-eye Zosterops senegalensis Bonaparte, 1850 (Zosteropidae), and Proterothrix terpsiphone sp. nov. from the African Paradise-flycatcher Terpsiphone viridis (Muller, 1776) (Monarchidae). Brief notes on systematics and host associations of the pterodectine genera Dolichodectes Park et Atyeo, 1971, Montesauria Oudemans, 1905, and Proterothrix Gaud, 1968 are also given.

The Afrotropical leaf-nosed bat Hipposideros caffer has been traditionally regarded as a complex of populations, currently pertaining to two recognized cryptic species, H. caffer and H. ruber. Extent of distribution and morphological variation of these bats has raised concerns over whether the current perception of the complex reflects true phylogenetic relationships and taxonomic diversity. Our phylogenetic analysis of nucleotide sequences of the mitochondrial cytochrome b gene challenged the hypothesis of two cryptic species. Instead of the two reciprocally monophyletic lineages expected, corresponding to the two species, we recovered four distinct lineages with deep internal divergences. Two sister clades within a lineage of bats of H. caffer represent respectively the nominotypical form H. c. caffer, restricted to Southern Africa, and H. c. tephrus, inhabiting the Maghreb, West Africa and the Arabian Peninsula. Geographical isolation and deep genetic divergence suggest species status of both the forms. Another lineage comprises specimens of both morphotypes from West and East Africa. It probably represents a distinct species but its taxonomic assignation remains obscure. A Central African lineage of H. ruber comprises two sister clades, which become sympatric in Cameroon. Their status has to be clarified with additional evidence, since nuclear gene flow might be taking place. A further divergent lineage with H. ruber morphotype, most probably representing another distinct species, is restricted to West Africa. Although all three genetic forms of H. ruber may correspond to named taxa, their proper taxonomic assignation has to be assessed by comparison with type material.

A total of 170 wild birds from Senegal, belonging to 48 species and 9 orders, were searched for lice in 2005 and 2007. Chewing lice were found on 58 birds of 18 species and 5 orders (Columbiformes, Cuculiformes, Coraciiformes, Galliformes and Passeriformes). Twenty-two species of chewing lice of 13 genera were determined. Other nine samples of chewing lice that represent a new host-parasite association were determined at generic level only, because only one sex or nymph of these lice were found. Our records represent the first louse records from passerines Camaroptera brachyura (Cisticolidae), Chalcomitra senegalensis (Nectariniidae), Corvinella corvina (Laniidae), Laniarius barbarus (Malaconotidae), Prinia erythroptera (Cisticolidae) and Turdus pelios (Turdidae). Descriptions and illustrations are given for Brueelia chalcomitrae Najer et Sychra sp. nov. ex Chalcomitra senegalensis (Nectariniidae), Brueelia priniae Najer et Sychra sp. nov. ex Prinia subflava (Cisticolidae), and Philopteroides terpsiphoni Najer et Sychra sp. nov. ex Terpsiphone viridis (Monarchidae).

Two mitochondrial lineages of bats that are morphologically attributed to Hipposideros ruber have been shown to occur sympatrically in southeastern Senegal. We studied genetic diversity in these bats in the Niokolo Koba National Park using sequences of mitochondrial cytochrome b gene to determine the taxonomie status of the two genetic forms, and included skull morphology for comparison. Detailed multidimensional analysis of skull measurements indicated slight morphological differences between the two genetic forms. Exploration of peak frequency of the constant-frequency echolocation signals in a local population of Hipposideros aff. ruber was not available for both groups. Phylogenetic comparison with other available West African representatives of H. aff. ruber revealed paraphyletic relationship of the two Senegalese forms, with the less abundant form from Senegal forming a monophyletic group with that from Benin. Based on genetic divergence and sympatric occurrence, the two forms from Senegal might represent cryptic species. However, absence of nuclear gene flow between them is yet to be investigated to demonstrate their reproductive isolation.

A West African species of gecko, Tarentola parvicarinata Joger (Gekkonidae), collected in the Niokolo Koba National Park in East Senegal is a new host species for the nematode Parapharyngodon echinatus (Rudolphi, 1819). Fifty one specimens of P. echinatus were studied under a light microscope and thirteen specimens were studied for the first time by a scanning electron microscope. The main differences between P. echinatus and other African species, especially Parapharyngodon micipsae (Seurat, 1917), were in the shape of annules on body cuticle, broad lateral alae and their terminations, the shape of the distal extremity of the spicule and number of outgrowths at the anterior cloacal lip. For the purposes of DNA characterization, partial sequence of the small subunit ribosomal RNA gene (SSU rRNA) was obtained from two specimens of P. echinatus. This is the first published sequence of a species from the family Pharyngodonidae.

This paper summarizes available information concerning the presence of the Eurasian lynx Lynx lynx Linneaus, 1758 in the Sumava Mountains and adjacent areas along the common border of Czech Republic, Germany and Austria. Our data give an overview of the lynx population occupying the border region between the three countries from 1990 to 1999. We estimated population size using radiotracking data. From 1990 to 1998, population increased from under 20 to nearly 70 resident animals. During this time, reproduction increased as well, with a maximum of 55 kittens observed in the rearing period of 1998 to 1999. Mortality data indicated that illegal hunting was widespread. Our paper discusses possible links with other lynx populations and describes the legal status of lynx in the three different countries. Current manage­ment approaches are outlined and steps toward a long-term conservation plan for the population are proposed.
