| Ground-living spiders on arable land in north-westem Switzerland with a Central European comparison (Arachnida: Araneae). The ground-living spider fauna of north-westem Switzerland is analysed in a general view during the years 1993-1998 based on 67 data sets. Two species (Oedothorax apicatus, Pardosa agrestis) dominated c1early. 14 species had representing values of 80 to 100 %, 9 species from 50 to 80% and 18 species from 20 to 50 %. Eperigone trilobata and Pardosa proxima are geographically typical. A total of 131 species and 52'878 adult spiders were included in this analysis. An additional analysis of 47 investigations around Central Europe yielded four species (Oedothorax apicatus, Erigone atra, Erigone dentipalpis, Meioneta rurestris) occurring... |

| Der Einfluss von eingesäten Wildblumenstreifen (Buntbrachen) auf die Laufkäfer- und Spinnenfauna der ehemaligen Flachmoorlandschaft und heute intensiv bewirtschafteten Kulturlandschaft "Grosses Moos" (Schweizer Mittelland: Berner Seeland) wurde untersucht. Drei mit einheimischen Wild- und Kulturpflanzen eingesäte Wildblumenstreifen verschiedenen Alters sowie die angrenzenden Getreidekulturen in 15 m (Randbereich) und in 70 bis 100 m (Zentrumsbereich) Entfernung vom Wildblumenstreifen wurden mittels Trichterbodenfallen während 10 Fangwochen von Mai bis Juli 1999 beprobt. Von den 123 in 44.161 Individuen nachgewiesenen Laufkäfer- und Spinnenarten wurden insgesamt 110 in Wildblumenstreifen, 85 in den Randbereichen und 82 Arten in den Zentrumsbereichen... |

| Flowery field margins and intersowing of crops with flowers are used as management practices to promote arthropod biodiversity as well as biocontrol agents. Positive effects of enhancement (in abundance and species richness) of hymenopteran parasitoids on control of Lepidoptera pests have previously been demonstrated. However, effects on predatory arthropods, which may also serve as pest control agents, remain unclear. In an experimental study in cabbage fields we tested how sown flower strips on field margins and intersowing with cornflower affected the species richness, abundance and community composition of ground beetles and spiders. Furthermore, we investigated whether effects of flower margins are dependent on the distance from the field margins. We... |

| Spiders from ecological compensation areas in the Swiss cantons Aargau and Schaffhausen (Arachnida: Araneae) - with remarks on Phrurolithus nigrinus (Corinnidae). The dpider fauna of open habitats adjacent to arable land was investigated in northern Switzerland. The three habitat types were (1) herbaceous edges of fields (Sa), (2) fallow land sowed with flowers (BB), and (3) grass borders of fields (GS). Four funnel pitfall traps (10 cm diameter) were used to catch spiders in three stripe-types in two geographical regions in two years over 5 weeks in May and June: in total 12 sets of data. Spider species typical for open habitats were dominant, mostly lycosids (6 of 10 most active species). The results were analysed together with environmental factors... |

| Aim: Conservation studies often investigate the biodiversity of one taxonomic group with the expectation that it reflects biodiversity of other taxa as well. However, previous studies have found that biodiversity patterns are often only weakly correlated across ecologically very different taxa. Using three arthropod taxa that share the same habitat, utilize similar resources and are sampled with identical technique, we investigate the applicability of two levels of biodiversity indication: (1) prediction of biodiversity patterns, and (2) inference of environment–biodiversity relationships. The second aspect is of high relevance to applied conservation management yet mostly neglected, at least in terrestrial systems, when discussing the indicator concept.... |
