New records of spiders from pond littorals in the Czech Republic
New records of spiders from pond littorals in the Czech Republic
Araneae
Abstract
Tmeticus affinis (Blackwall, 1855), Tetragnatha shoshone Levi, 1981, Clubiona juvenis Simon, 1878, Marpissa Canestrinii Ninni, 1868, and Theridiosoma gemmosum (L. Koch, 1877) are new records for the Czech Republic. New data about Enoplognatha caricis (FICKERT, 1876), Theridion hemerobium SIMON, 1914, Rugathodes instabilis (O. P. CAMBRIDGE, 1871), Tetragnatha striata L. KOCH, 1862, and Dolomedes plantarius (CLERCK, 1757) are given. The validity of the name Enoplognatha caricis (FICKERT, 1876) is supported.
Boden- und baumstammbewohnende Linyphiidae des Hienheimer Forstes (Bayern) (Arachnida: Araneae)
Soil- and trunk-inhabiting linyphiids of the Hienheimer Forst (Bavaria, Germany)
spiders; different trap-systems; soil; stem; nature forest reserves; managed forest; habitat requirements
Abstract
This paper presents some results of a forest ecology research project by the University of Munich’s faculty of Forestry, involving the comparison of forests designed to reflect varying degrees of naturalness. Spiders on the ground and on trunks in four different forests in the Hienheimer Forst were caught with 24 ground photo eclectors, 8 arboreal eclectors and with 40 pitfall traps. Habitat requirements were measured and analysed with particular attention to forest soil. Abiotic parameters and the structure of the litter layer were recorded. The most frequent spiders were the Linyphiidae, Agelenidae and Amaurobidae.63 species of the family Linyphiidae were caught. One half of the Linyphiidae-species could be found on trunks of oak and spruce (eclector fauna). In terms of the number of spider species and in the portion of rare and endangered species there were almost no differences between commercial forest areas and conservation areas. The differences are not as great as the original classification according to closeness to the natural state had led us to expect.
Trogulus martensi Chemini, 1983 im Raum Basel (Arachnida, Opiliones, Trogulidae)
Trogulus martensi Chemini, 1983 from the Basle area (Arachnida, Opiliones, Trogulidae)
Trogulus; Opiliones; Switzerland; France; first records; ecology; biometry
Abstract
Trogulus martensi Chemini, 1983, formerly thought to be endemic in northern Italy, is recorded from several places near Basle (first records in Switzerland and France). The species is close to T. galasensis Avram, 1971. Important differences to the syntopic T. closanicus Avram, 1971 (first published record in Fance) and the sympatric T. nepaeformis (Scopoli, 1763) are shown and discussed. Additional biometric, autecological and phenological data of Trogulus martensi are presented.
