Příspěvek popisuje velmi neobvyklý nález mloka skvrnitého (Salamandra salamandra), který byl zaznamenán ve výšce 2 m nad zemí šplhající po kmeni vzhůru. Z literatury je sice známo vyhlížení samic samci z vyvýšených míst, ale tento nález je velmi odlišný. Důvod tohoto výjimečného chování je neznámý., The species is usually encountered on the ground, stones or lying wood not too high above ground. However, I found one individual climbing up a tree at a height of two metres. Unfortunately, nothing is known of the motives behind this unusual behaviour., and Antonín Krása.
Boreal peatlands of the Třeboň Basin (South Bohemia) contain many distinctive taxa of Lepidoptera, including tyrphobionts and tyrphophiles. These ancient peatlands are oligotrophic and acidic, and form habitat islands – relict ecosystems related to subarctic/ boreal biomes. They host isolated populations of cold-adapted Lepidoptera, some of them associated with common bo - real plants. For instance, larvae of several relict boreal and subarctic moths (e.g. Eupi - thecia gelidata) feed exclusively on the lo - cal Marsh Labrador Tea (Ledum palustre). and Josef Jaroš, Karel Spitzer.
Příspěvek přináší informace o nepůvodních savcích ostrova Sokotra a jejich vlivu na místní ekosystémy. Nejvýraznějším problémem je nadměrná pastva dobytka. Nadměrné spásání je výsledkem rostoucí početnosti populací domácích zvířat, zejména koz v důsledku zvýšené poptávky po mase, změny způsobu chovu a vymizením tradičního kočovného pastevectví. Důsledkem je pak nárůst půdní eroze, změna a destrukce původních rostlinných společenstev i úbytek populací endemických druhů živočichů. Snížení počtu koz na ostrově i změna způsobu jejich chovu jsou nutnými kroky zdejší ochrany přírody., This article presents information about the alien mammal species of Socotra Island and their impact on local ecosystems. The most important problem is overgrazing by livestock. It is a result of rising numbers of domestic animals, mainly goat populations, as a consequence of higher demand for meat, change of breeding style and the disappearance of traditional nomadic pasturage. This situation leads to increasing soil erosion, change and destruction of native plant populations and decreasing endemic animal species populations., and Josef Suchomel.
Recently, malaria is remain considered as the most prevalent infectious disease, affecting the human health globally. High morbidity and mortality worldwide is often allied with cerebral malaria (CM) based disorders of the central nervous system, especially across many tropical and sub-tropical regions. These disorders are characterised by the infection of Plasmodium species, which leads to acute or chronic neurological disorders, even after having active/effective antimalarial drugs. Furthermore, even during the treatment, individual remain sensitive for neurological impairments in the form of decrease blood flow and vascular obstruction in brain including many more other changes. This review briefly explains and update on the epidemiology, burden of disease, pathogenesis and role of CM in neurological disorders with behaviour and function in mouse and human models. Moreover, the social stigma, which plays an important role in neurological disorders and a factor for assessing CM, is also discussed in this review., Arif Jamal Siddiqui, Mohd Adnan, Sadaf Jahan, Whitni Redman, Mohd Saeed and Mitesh Patel., and Obsahuje bibliografii
A new fossil genus and species of Sinoalidae, Stictocercopis wuhuaensis gen. et sp. n., from the Middle to Upper Jurassic Haifanggou Formation at Daohugou, Inner Mongolia, northeastern China is described, illustrated and its systematic position discussed, on the basis of four complete well-preserved specimens. The new genus distinctly differs from other sinoalids in having relatively complex wing venation and tegmen spots. The intra-specific variation in venation is also discussed. The new discovery increases the palaeodiversity of sinoalids in the early assemblage of the Yanliao biota from the Daohugou beds., Yan-Zhe Fu, Di-Ying Huang., and Obsahuje bibliografii
Three species of nematodes from the Camallanidae that are known to infect Xenopus laevis Daudin (Anura: Pipidae) were collected from several localities across South Africa. New data on morphology, partial 28S and cox1 genes, infection levels and distribution are presented herein. The most common species, Batrachocamallanus slomei Southwell et Kirshner, 1937, from the stomach and less often oesophagus, was found in eight localities. Camallanus kaapstaadi Southwell et Kirshner, 1937, also from the oesophagus, was found in two localities and C. xenopodis Jackson et Tinsley, 1995, from the intestine, at a single locality. New localities for both C. kaapstaadi and C. xenopodis provide a geographical range extension. Males of C. xenopodis are described for the first time herein. The existence of a left spicule in the males of both the species of Camallanus Railliet and Henry, 1915 is confirmed and measurements are provided. Although C. xenopodis is distinguished from C. mazabukae Kung, 1948 in the present study, we suggest greater sampling effort in other African amphibians to confirm the species status of the latter taxon. Finally, the new molecular data showed distant relationships between collected species of Camallanus and species parasitising fish and freshwater turtles., Roman Svitin, Anneke L.

The following six species of the Philometridae (Nematoda: Dracunculoidea) were recorded from marine fishes off the northern coast of Australia in 2015 and 2016: Philometra arafurensis sp. n. and Philometra papillicaudata sp. n. from the ovary and the tissue behind the gills, respectively, of the emperor red snapper Lutjanus sebae (Cuvier); Philometra mawsonae sp. n. and Dentiphilometra malabarici sp. n. from the ovary and the tissue behind the gills, respectively, of the Malabar blood snapper Lutjanus malabaricus (Bloch et Schneider); Philometra sp. from the ovary of the goldbanded jobfish Pristipomoides multidens (Day) (Perciformes: all Lutjanidae); and Digitiphilometroides marinus (Moravec et de Buron, 2009) comb. n. from the body cavity of the cobia Rachycentron canadum (Linnaeus) (Perciformes: Rachycentridae). Digitiphilometroides gen. n. is established based on the presence of unique digital cuticular ornamentations on the female body. New gonad-infecting species, P. arafurensis and P. mawsonae, are characterised mainly by the length of spicules (252-264 µm and 351-435 µm, respectively) and the structure of the gubernaculum, whereas P. papillicaudata is characterised mainly by the body length (70 mm) of gravid female, extent of the oesophageal gland, size of caudal projections and the location in the host. Dentiphilometra malabarici differs from congeners mainly in the arrangement of circumoral teeth (in a single row), extent of the oesophageal gland and the absence of sclerotised teeth or protuberances on the oesophageal lobes in the mouth. Digitiphilometroides marinus has not previously been reported from fishes in Australian waters., František Moravec, Diane P. Barton., and Obsahuje bibliografii

Three new species of Aberrapex Jensen, 2001 (Cestoda: Lecanicephalidea) have been collected from species of Myliobatis Cuvier along the coast of Argentina. Aberrapex ludmilae sp. n. parasitises M. goodei Garman in the San Matías Gulf. This species is unique in a combination of features including the shape and extent of the uterus, scolex size, testis distribution, and by lacking an external seminal vesicle and postovarian vitelline follicles. Aberrapex sanmartini sp. n. from M. goodei in San Blas Bay and A. vitalemuttiorum sp. n. from M. ridens Ruocco, Lucifora, Díaz de Astarloa, Mabragaña et Delpiani in coastal waters off Buenos Aires Province, are distinguished from all other congeners by the microthrix pattern on the scolex surface, uterus shape and extension, position of the connection of the uterine duct to the uterus, presence and extension of an external seminal vesicle, and its overall size and number of proglottids. The specimens of M. goodei and M. ridens show locally distinct cestode faunas, which are correlated with well-defined biogeographic regions. Some of these areas correspond with mating and nursery zones for species of Myliobatis., Adriana Menoret, Leonardo Mutti, Verónica A. Ivanov., and Obsahuje bibliografii
