The monotypic genus Silvispina M. Wang & Soulier-Perkins, gen. n. and new species S. changpotou M. Wang & Soulier-Perkins, sp. n. belonging to the family Lophopidae Stål, 1866, from Yunnan Province in China, is described and illustrated. The peculiarity of the first metatarsal segment of this genus is stressed and the taxonomic position of this new genus is discussed. The ornamentation and shape of metatibia and first tarsal segment (the characters that currently distinguish the subfamilies Menoscinae and Lophopinae) do not agree with either subfamily and the new genus is placed as incertae sedis in the Lophopidae. The genus Ridesa Schumacher, 1915 is removed from the family Lophopidae and placed in the Achilidae., Menglin Wang, Yinglun Wang, Adeline Soulier-Perkins., and Obsahuje bibliografii
Kančilové (Tragulidae) jsou málo známí obyvatelé tropických lesů západní Afriky, jižní a jihovýchodní Asie. Cílem tohoto článku je proto shrnutí všech nových informací, a to jak o jejich taxonomickém postavení mezi ostatními kopytníky, tak i o jejich vnitřním členění včetně základních charakteristik jednotlivých druhů. Následuje shrnutí jejich základní ekologie a etologie. Závěrečná část článku je pak věnována problematice jejich ochrany a přehledu jejich chovu v českých zoologických zahradách., Chevrotains or mouse deer (Tragulidae) are rarely studied inhabitants of the rainforests of Africa, south and south-east Asia. This article summarizes the latest knowledge about their taxonomy including the basic features of individual species, and describes their ecology and ethology. It also deals with conservation issues and provides a detailed survey of keeping and breeding chevrotains in Czech zoos., Jan Pluháček., and Obsahuje seznam literatury
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.
A new progonocimicid bug named Cicadocoris parvus sp. n. is described from the mid-Jurassic Haifanggou Formation at Daohugou, Ningcheng County, Inner Mongolia, northeastern China. It differs from other species by being distinctly smaller, veins dSc, R1 and Rs run parallel to one another and are nearly evenly spaced on left tegmen, widest length of apical half/basal half of left tegmen is 1.1 and that of right tegmen is 1.0. Thus, there are at least three species of Cicadocoris (Progonocimicidae) described from Daohugou. All these species are relatively abundant in the Haifanggou Formation and are remarkable representatives of the early Yanliao biota., Jia-Qian Jiang, Di-Ying Huang., and Obsahuje bibliografii
We analyzed the abundance, distribution and niche overlap of species (Pianka's Ojk index) in tenebrionid beetle communities inhabiting different biotopes in Tyrrhenian and Adriatic sand dunes. The rank abundance distribution of the different species has the form of a geometric series in both communities as predicted by the niche preemption hypothesis for communities in harsh environments. Mean niche overlap values did not deviate significantly from null expectations, which indicates random interspecific interactions. These results, coupled with evidence of species habitat preferences, led us to conclude that the community organization of tenebrionid species inhabiting coastal dunes is determined more by habitat preferences than interspecific competition., Simone Fattorini, Davide Bergamaschi, Cristina Mantoni, Alicia T.
