Pro rok 2013 se stal evropským pavoukem roku sklípkánek hnědý (Atypus affinis). Jde o jednoho ze tří druhů sklípkanů vyskytujících se v České republice. V článku popisuji morfologii, způsob života, stanovištní nároky a rozšíření sklípkánka hnědého. Je naším nejhojnějším zástupcem rodu, vyskytuje se na suchých osluněných kamenitých stráních s řídkou stromovou vegetací. Jeho stanoviště nejsou bezprostředně ohrožena sílícím zarůstáním krajiny., The Purse-Web Spider (Atypus affinis) became the European Spider of the Year 2013. The genus Atypus comprises three species in Europe. The morphology, natural history, habitat requirements and distribution of A. affinis are described. In Central Europe, it is the most common Atypus species and it occurs on dry sunny rocky slopes with sparse woody vegetation. These habitats do not tend to be overgrown by expansive tree or grass species., and Milan Řezáč.
Ray-finned fishes (Actinopterygii) are by far the most diversified group of vertebrates on Earth, and there are currently more than 32500 valid species in about 500 families and 72 orders. The diversity of ray-finned fishes has increased dramatically during their evolution, particularly in the modern group of Percomorpha. This also includes high morphological diversity of body shapes. However, in many cases similar morphological structures have evolved in different groups independently (by convergence). Recently, fish phylogeny has been reconstructed based on molecular genetic data, including whole genome sequencing. In this issue we present two articles on general relationships among the main lineages of fishes and the current version of the phylogeny of the ray-finned fishes. and Zuzana Musilová.
The article presents the characteristic features of the worldwide wolf spider family (Lycosidae) and describes how its study has affected Czech arachnology, which takes credit for resolving several issues. Among the 38 families of spiders living in the Czech Republic, wolf spiders are remarkable for their ecology. Wolf spider vital signs are so prominent that every observer inevitably notices their constant movement. In addition to history of the research into the wolf spider family, some faunistic issues are also presented. and Jan Buchar.
The second part of this article on the wolf spider family (Lycosidae) and the importance of Czech arachnologists in its study deals with various questions involving the taxonomy, zoogeography, ecology, bioindications and protection of these spiders, as well as their etology and cytogenetics. and Jan Buchar.
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.
