Phänologie und Lebenszyklus von Wolfspinnen (Araneae, Lycosidae) auf Wirtschaftswiesen des Altmühltales/Bayern
Phenology and life cycle of wolf spiders (Araneae: Lycosidae) from meadows of the Altmühl Valley (Bavaria, Southern Germany)
Lycosidae; phenology; life cycle
Abstract
A faunistic study was carried out for two years in the valley of the river Altmühl in 1986 and 1987. With the help of 57 BARBER-traps in meadow habitats near Weissenburg-Gunzenhausen more than 14500 adult and 7700 young wolf spiders were caught. 13 species were found in total: Alopecosa pulverulenta (CLERCK), Arctosa leopardus (SUNDEVALL), Aulonia albimana (WALCKENAER), Pardosa agrestis (WESTRING), Pardosa amentata (CLERCK), Pardosa palustris (LINNE), Pardosa palluta (CLERCK), Pirata hygrophilus THORELL, Pirata latitans (BLACKWALL), Pirata piraticus (CLERCK), Pirata piscatorius (CLERCK), Trochosa ruricola (DE GEER) and Trochosa spinipalpis (F.P.-CAMBRIDGE). The pit-fall traps were installed throughout the year and were controlled every two weeks. The resulting data allow a detailed description of the life cycle of seven species: Alopecosa pulverulenta, Pardosa amentata, Pardosa palustris, Pardosa pullata, Pirata latitans, Pirata piraticus and Trochosa spinipalpis. The life cycle of Alopecosa, Pardosa and Pirata species was found last year. Trochosa species need almost two years to reach maturity.
Die epigäische Spinnenfauna eines Auwaldgebietes der Donau im Landkreis Dillingen/Donau (Deutschland, Bayern)
Ground-living spiders in a floodplain forest area of the Danube river in Bavaria (Germany)
Araneae; faunistics; riparian forest
Abstract
The ground-living spider fauna of a drained floodplain forest area was investigated at 5 sites in the vicinity of the Danube river near Dillingen/Bavaria. Four series of pitfall traps were set up in the forest area, while a fifth series was installed in a dry, sunny clearing. Observation period was from early April through late November 1985. A total number of 1447 adult spiders belonging to 94 species were caught. The main result was that the small, dry clearing area harbours a rather specific spider community that is distinctly different from those of the neighbouring wet areas in the forest.
Zur Autökologie der Spinnen (Arachnida: Araneae). I. Charakteristik der Habitatausstattung und Präferenzverhalten epigäischer Spinnenarten
On autecology of spiders (Arachnida: Araneae). I. Characterization of habitat and habitat preference of epigeic spiders
Araneae; habitat preference; habitat characterization
Abstract
The preferences to several properties of habitats (4 levels of humidity and light exposure, 7 kinds of habitat structure and 7 types of biotops) are given in form of an ecogramm for 320 species of spiders living in strata near the ground. A simple method for habitat analyisis is presented
Kommentierte Artenliste der Spinnen Bayerns (Araneae)
Commented checklist of the spiders of Bavaria (Germany)
Araneae; check list; faunistics; Germany; Bavaria
Abstract
The checklist contains informations on records after 1970 in seven bavarian counties ("Bezirke") an in whole Bavaria before 1970. A total of 747 species is known from Bavaria. 14 species (Dysdera ninnii, Gonatium ensipotens, Hilaira montigena, Janetschekia monodon, Lessertinella kulczynskii, Peponocranium praeceps, Scotinotylus antennatus, Trichoncus simoni, Bathyphantes setiger, Lepthyphantes jacksonoides, Lepthyphantes variabilis, Maro lehtineni, Tricca alpigena, Gnaphosa rhenana) are mentioned here for the first time in Germany, 11 are new for southern Germany and 43 new for Bavaria.
