- Description:
- Nosorožci tuponosí (Ceratotherium simum) a Cottonovi (Ceratotherium cottoni) mají nejvyvinutější sociální systém ze všech druhů nosorožců, přesto toho o jejich sociálním chování a především komunikaci bylo donedávna známo jen málo. V článku jsou popisovány výsledky čtyř recentních studií, které se zabývaly sociálním chováním a vokální a olfaktorickou komunikací obou druhů v rezervacích v Jihoafrické republice i v zoologických zahradách., The Northern and Southern White Rhinos (Ceratotherium cottoni and C. simum) have the most developed social system among all the rhinoceros species. Until recently, little has been known about their communication and social behaviour. This paper presents the results of four recent studies involving research into the social behaviour and vocal and olfactory communication of these species both in the wildlife reserves in South Africa and in zoological gardens., and Ivana Cinková.

- Description:
- Fourteen species (twelve adult and two larval) of nematodes belonging to the Ascaridoidea, Camallanoidea, Cosmocercoidea, Habronematoidea, Oxyuroidea, Seuratoidea and Trichinelloidea were collected from fishes in the Sudan (River Nile and Atbara Dam Lake), whereas only four species (one adult and three larval) of the Ascaridoidea, Camallanoidea, Dioctophymatoidea and Trichinelloideafrom fishes in Ethiopia (Lake Tana). The Sudanese material also contained two previously unknown species, Cucullanus mormyri sp. n. from Mormyrus caschive Linnaeus (type host), Mormyrus sp. and Marcusenius cyprinoides (Linnaeus) (all Mormyridae), and Procamallanus (Spirocamallanus) pseudospiralis sp. n. from Synodontis schall (Bloch et Schneider) (type host), S. frontosus Vaillant and S. nigrita Valenciennes (all Mochokidae), which are described based on light and scanning electron microscopical studies. Cucullanus baylisi Campana-Rouget, 1961, a little-known parasite of Synodontis spp., is redescribed in detail. A key to Procamallanus (Spirocamallanus) spp. from African inland fishes is provided. Falcaustra guiersi Vassiliadès, 1973 is considered a junior synonym of F. hexapapillata (Khalil, 1962). The findings represent several new host and geographical records. Cucullanus baylisi Lakshmi, 2000 (= a homonym to C. baylisi Campana-Rouget, 1961) is re-named as C. dubius nom. n. and is considered a species inquirenda., František Moravec, Tomáš Scholz., and Obsahuje bibliografii

- Description:
- a1_Based on light and scanning electron microscopical studies, eight species (five adult and three larval) of nematodes belonging to the Ascaridida, Oxyurida and Enoplida were collected from fishes of the Okavango River, Botswana, namely Falcaustra similis Moravec et Van As, 2004, Atractidae gen. sp. (only female) (both Cosmocercoidea), Cucullanus sp. (only female) (Seuratoidea), Cithariniella longicaudata sp. n., Synodontisia annulata sp. n. (both Oxyuroidea), Contracaecum sp. third-stage larvae, third-stage larvae of Galeiceps sp. (both Ascaridoidea) and Eustrongylides sp. fourth-stage larvae (Dioctophymatoidea). The new species Citharinella longicaudata (type host Schilbe intermedius Rüppel) is mainly characterised by the shape and size of cephalic papillae and the spicule 108 µm long, and Synodontisia annulata (type host S. intermedius) by the shape of cephalic papillae, body length of gravid females (4.88-5.33 mm) and a short spicule (66 µm long). The female specimen of Cucullanus sp. from Tilapia sparmanni Smith markedly differs from congeners parasitising inland fishes in Africa by the elongate pseudobuccal capsule and by the excretory pore far posterior to the oesophago-intestinal junction; apparently, it belongs to an undescribed species. Galeiceps larvae parasitising fishes are described for the first time. Cithariniella gonzalezi Van Waerebeke, Chabaud, Bain et Georges, 1988 is considered a junior synonym of C. khalili Petter, Vassiliadès et Troncy, 1972, and the previous records of Cithariniella citharini Khalil, 1964 from Synodontis spp. in Egypt concern, in fact, Cithariniella khalili Petter, Vassiliadès et Troncy, 1972., a2_The specimens of Cithariniella reported by Koubková et al. (2010) from Paradistichodus dimidiatus (Pellegrin) in Senegal and misidentified as C. gonzalesi Van Waerebeke, Chabaud, Bain et Georges, 1988 are considered to represent a new species, C. koubkovae sp. n.; this is established by reference to the description and drawings provided by Koubková et al. (2010)., František Moravec, Liesl L. Van As., and Obsahuje bibliografii

45. The development and fine structure of Lankesterella cf. dicroglossi (Apicomplexa: Lankesterellidae) infecting frogs in Niger, West Africa

- Subject:
- Lankesterella cf. dicroglossi, infection, ultrastructure, frog, Hoplobatrachus occipitalis, Niger, and Africa
- Language:
- English
- Description:
- One of four Hoplobatrachus occipitalis (Günther, 1859) frogs received from Niger, West Africa was heavily infected with Lankesterella blood and pre-erythrocytic stages. Infected blood and tissues from this frog were force-fed to the remaining three frogs. Two survived to necropsy on days 14 and 27 post-feeding and were found to be infected with gamogonic and oogonic stages, respectively. The source of infection is inconclusive, as a natural origin cannot be excluded. Microgamont, macrogamont, oocyst and sporozoite structure and fine structure are described and found to conform in general, but not in detail, to previous descriptions. Gamonts and oocysts occurred predominantly in the liver and spleen. Walled sporulating oocysts were situated within macrophage centres. Oocysts yielded a progeny of 32 sporozoites. Pre-erythrocytic sporozoites developed within expanded inclusions, within their host cell, from which they massively invaded the liver and spleen, and to a lesser extent the lungs and kidneys. Sporozoites occurred in a parasitophorous vacuole in the erythrocytes. Conspecificity with Lankesterella dicroglossi Paperna et Ogara, 1996 reported from the same host species in Kenya remains uncertain due to several structural and developmental differences.

- Description:
- Two new species of Cylicospirura Vevers, 1922 are described from carnivores from southern Africa. Cylicospirura crocutae Junker et Mutafchiev sp. n. from Crocuta crocuta (Erxleben) in Zimbabwe is distinguished from its congeners by combinations of characters, including the presence of four cephalic and four external labial papillae, while internal labial papillae were not distinct, the presence of groups of small accessory teeth between the six large tricuspid teeth, the fifth and the sixth pairs of the caudal papillae being equidistant from the cloaca, and a large ratio of length of the muscular oesophagus to that of the glandular oesophagus. Cylicospirura pardalis Junker et Mutafchiev sp. n. from Panthera pardus (Linnaeus) in the Republic of South Africa is characterized by having tricuspid teeth with large, claw-like, abaxial cusps, four cephalic and six internal labial papillae. Based on the number of caudal papillae and the position of the vulva, the subgenera Gastronodus Singh, 1934 and Skrjabinocercina Matschulsky, 1952 are re-elevated to generic rank. Amended diagnoses are proposed for the genera Cylicospirura, Gastronodus and Skrjabinocercina. Petrowospirura lyncis Matschulsky, 1952 is recognized as valid and, together with P. petrowi Sadykhov, 1957 and P. barusi Arya, 1979, is transferred to Cylicospirura as C. lyncis (Matschulsky, 1952) Junker et Mutafchiev comb. n., C. petrowi (Sadykhov, 1957) Junker et Mutafchiev comb. n. and C. barusi (Arya, 1979) Junker et Mutafchiev comb. n., respectively.

49. Wien, Trionfi-lavabo, mísa: Fauni, grotesky, čtyři říše a čtyři světadíly.
- Creator:
- Jamnitzer, Christoph
- Publisher:
- Rudolf II.,
- Subject:
- Africa, America, Asia, Europa, Faunus, grottesche, and imperium
- Description:
- Na okraji je na obou kratších stranách puncovaný groteskový ornament, do něhož jsou zakomponováni tři Fauni. Na vnitřním okraji mísy sedí drobné plastiky čtyř chlapců symbolizijících čtyři světadíly (počínaje vlevo nahoře po směru hodinových ručiček): Asie, Amerika, Evropa a Afrika. Na okraji jsou v osách medailony se zvířaty symbolizujícími čtyři světové říše podle proroka Daniela (po směru hodinových ručiček zprava): zlatý lev (babylonská říše krále Nina), stříbrný medvěd (perská říše krále Kyra), bronzový čtyřhlavý panter (řecká říše Alexandra Velikého), železné zvíře s deseti rohy (římská říše Julia Caesara)., Irmscher 1999#, 116-121., and V době, kdy pracoval na Trionfi-lavabo, Jamnitzer vydal sborník grotesek (Jamnitzer 1610). Groteskový ornament na míse se tematicky vztahuje k tělesné lásce a chtíči, který představují Fauni, z nichž ten vpravo dole má křídla a je tak ztotožněn se Satanem. Universální charakter říše římské zdůrazňuje čtveřice symbolů světadílů. Série symbolů říší předpovězených prorokem Danielem (Dan 7) končí symbolem říše římské umístěné na nejdůležitějším místě, dole uprostřed. Nad železným zvířetem symbolizujícím říši římskou je řada císařů končící Rudolfem II., čímž je podle cyklického pojetí času předpovězen návrat k počátkům a tedy příchod Zlatého věku.

- Subject:
- Africa, foreigner, integration, communication, migration, and mixed marriage
- Language:
- Czech
- Description:
- The percentage of transnational marriages is quite low in Slovakia. This relates to the increasing mobility of domestic inhabitants abroad as well as to the arrival of foreigners in Slovakia during recent decades. The study is to explain the cultural and historical background of mixed marriages between Slovaks and foreigners, their family life and the integration in the Slovak environment, namely in the context of migration experience of the partners in these relationships. In the introduction, we characterize the transnational marriages using available statistical data. We will investigate the integration processes on selected type of transnational marriages, in which the partner comes from Egypt, Algeria or Tunis. We will focus mainly on their communication strategies and employability in the labour market.
