Abstract
Lycosid and linyphiid spiders were collected over a full cropping season around Uppsala, Sweden, in eight organic spring sown cereal fields in three different habitat types: field margin, field, and the edge between the two. The sites were located in landscapes with different proportions of non-crops, forest, perennial crops, annual crops, and number and sizes of arable fields. The field margin, compared with the field habitat, was found to be important for the activity density of lycosids, and for the species richness and composition of linyphiids. Landscape parameters were central for the activity density of linyphiids and for the species richness and composition of Lycosidae. A diverse landscape with easy access to perennial crops and forest in addition to field margins will augment both the number of species and individuals of the two spider families.

It is argued that for the management and development of sustainable ecosystems, it is probably more important to understand the linkages between key species or functional groups and ecosystem function, rather than focusing on species diversity.

EcologySPECIES IDENTITY DOMINATES THE RELATIONSHIP BETWEEN PREDATOR BIODIVERSITY AND HERBIVORE SUPPRESSION
243 Citations2006Cory S. Straub, William E. Snyder
Experiments revealed strong effects of predator species identity, because predators varied dramatically in their per capita consumption rates, and suggest that, for the biological control of aphids, conservation strategies that directly target key species will be more effective than those targeting predator biodiversity more broadly.

Field evidence for intraguild interference among generalist ground predators in arable land is provided, despite this interference the polyphagous predator community was able to depress numbers of aphids in winter wheat, a result cascading down to plant quality parameters.

It is found that many spiders and carabids are present in the fields after sowing in spring and have the opportunity to suppress aphids during their establishment phase, which in turn may prevent a possible outbreak.

Results indicate that for species with a high potential for aerial dispersal like Erigone atra (Blackwall) (Araneae: Erigonidae), the proximity of refuge habitats is less important than for species that disperse predominantly over the soil surface like O. apicatus.
