vipes. The really terricolous species are rare: Nemastoma lugubre and bimaculatum, Lophopilio palpinalis, Oligolophus tridens. E3: Terricolous species appear in the forest patch with 70% canopy cover throughout the year: Lacinius horridus, Phalangium opilio. Spring and at the beginning of summer: Zacheus crista, Rilaena triangularis; only in autumn: Astrobunus laevipes. The sciophylsous species are present only with a few individuals: Nemastoma lugubre, bimaculatum, Lophopilio palpinalis, Oligolophus tridens. E2: This close "dark" microhabitat is a cool but not humid. Only a few Opiliones occur here. The Mediterranean xero-thermophilous Zacheus crista dominates here from spring till summer. At the beginning of the summer the mountaine species Rilaena triangularis and Lacinius horridus were frequent in the traps. Phalangium opilio appeared, too. The wet meadow is insolated and flooded by water in spring and autumn. It has a high level of humidity on the soil surface. The species structure consists of species indicating high humidity: Astrobunus laevipes, Oligolophus tridens, Lophopilio palpinalis and of species requiring less humiditiy, as well: Lacinius horridus, Phalangium opilio, Opilio parietinus. The Mediterranean Zacheus crista reaches here the northern limit of its distribution. The tall sedge biotope can be characterised with sciophilous species: Lacinius horridus, Phalangium opilio and Zacheus crista. There are only a few individuals of species indicating high humidity, such as Astrobunus laevipes , Lophopilio palpinalis. This is the poorest biotope, considering both the species number and individual number of Opiliones.
