Millipedes (Diplopoda) in birdsˈ nests

Abstract Nests of birds represent an unusual microhabitat for diverse groups of soil and epigeic invertebrates including millipedes. The millipede faunas of 301 birdsˈ nests from 63 localities throughout Slovakia were obtained by heat extraction of the nest substrates. In total 18 species of millipedes were found in 7 different types of nests of 40 bird species. The most frequent millipede species were Polyxenus lagurus and Proteroiulus fuscus. The similarities in the millipede nidifauna depending on the type of nests, ecological characteristics and geographical distribution of millipede species are discussed.

Allocaeculus sandbergensis sp. n. (Acari: Caeculidae), a new prostigmatid mite from Slovakia

In January and in May 2012 three individuals (two adults and one nymph) from the genus Allocaeculus (family Caeculidae) were found in the area of the National nature reserve Devínska Kobyla near Sandberg (SW Slovakia). This mite family has not been recorded in Slovakia yet. Data about its nearest occurrence come from the Czech Republic and Austria. Based on the specimens, Allocaeculus sandbergensis sp. n. is described.

Classification of epigeic spiders (Araneae) at the western part of the Carpathians (Slovakia)

The epigeic spider communities of the Western Carpathians are characterised by a high number of species. The great influence of Pannonian elements on the coenoses of the Carpathian hills is evident. The habitats of the Western Carpathians differ from each other, and several types of microclimatic conditions are there. These facts affect the spider fauna. The epigeic spider communities of the western part of the Carpathians, represented by the Devínska Kobyla hill, were characterized by the constant presence of four species at all study sites — Dysdera erythrina, Agroeca cuprea, Pardosa lugubris and Trochosa terricola. Principal components analysis confirmed the high proportion of Trochosa terricola, Eresus moravicus and Scotina celans in the epigeic spider community of the steppe. In contrast, the presence of Coelotes inermis, Histopona torpida and Haplodrassus silvestris was important in the oak forest. Bray-Curtis analyses confirmed that the spider community of the oak forest differed. The migration and penetration of the species with high vagility was an important fact that affected the spider community in the ecotones. Based on the analysis of the araneocoenoses in the Western Carpathians, spiders were grouped into four categories — leaders, typical spiders, specific spiders and tourist species.
