Overwintering of spiders in leaf litter of the non-production elements of woody vegetation in the agricultural landscape

Popis výsledku v původním jazyce

The long-term survival of arthropod populations in a landscape relies on successful hibernation. Leaf litter of non-production elements of woody vegetation, such as solitary trees, groups of trees in line formation and non-linear groups of trees can provide suitable overwintering habitats for arthropods. In South Moravia, we can find in general three types of agricultural landscapes which differ in the ratio of arable land to orchards and vineyards and in the size of the landscape grain: the landscape with 1) the prevalence of arable land (AL); 2) the prevalence of orchards/vineyards (OV); and 3) the same proportion of arable land and orchards/vineyards (AL-OV). We investigated the importance of leaf litter in these three agricultural landscapes and woody vegetation formation types as overwintering habitats for spiders. Leaf litter was sampled from an area of 1 m2 in three types of woody vegetation formation in each agricultural landscape (20 samples per woody vegetation formation type in each landscape, in late autumn and early spring; altogether 360 samples). Leaf litter was sifted in a laboratory and spiders were placed in the ethanol and determined. Significant differences in spider assemblages were found between landscape types, specifically between OV and AL-OV (p = 0.02) and OV and AL (p = 0.04), woody vegetation formation types, namely between the non-linear group of trees and solitary type (p &lt; 0.001) and between the linear and solitary type (p &lt; 0.001), and sampling seasons (p &lt; 0.001).
