Dendrocopos Syriacus

Abstract Non-forest tree stands are important habitats for many species of birds in the agricultural landscape. They are also the main habitat of the Syrian Woodpecker Dendrocopos syriacus, whose numbers have been decreasing in recent years in some parts of Europe. Recognition of the habitat requirements of this species may help better planning of its protection in the context of the treed agricultural landscapes. During this study, the habitat preferences of the Syrian Woodpecker were determined in the agricultural landscape of South-Eastern Poland. A set of 12 habitat parameters of tree stands located in the breeding territories of the Syrian Woodpecker (n = 122) and in randomly chosen control areas (n = 122) located outside the range of the breeding territories of this species were characterized. The number and species diversity of trees was significantly higher in stands located in Syrian Woodpecker territories than in the random control areas. Stands occupied by breeding pairs also had trees of worse health condition and a larger proportion of fruit trees. The model best explaining the probability of the occurrence of the species indicates that the Syrian Woodpecker requires mainly the presence of tree stands with a greater species diversity of trees, as well as tree stands in worse health condition. When planning the protection of this species’ habitats in the agricultural landscape, the characteristics of non-forest tree stands noted above should be taken into account.

AbstractThe species of the megerlei-group are characterised by shortened wings with typical scattered dark spots and large simple glands on tergite 7 without inner structures. Two of the species are widely distributed from south-eastern Germany to Romania and Ukraine (P. megerlei Fieber) or from Turkey to Syria (P. asiatica Bey-Bienko), the third is endemic for eastern Bulgaria (P. pulcherrima sp. n.). The characteristics of the megerlei-group are described and the relationships with the tyrrhenica-group are discussed.

Habitat structure, at a scale at which we do not normally perceive it, can be an important determinant of species diversity and distribution in arboreal mites. Phytoseiid mites (1552 individuals) collected from the leaves of 75 species of woody plants from 55 forest sites between Noosa Head, Queensland and the Hartz Mountains, Tasmania were found to represent 28 species in four genera: Phytoseius, Typhlodromus, Amblyseius and Iphiseius. About half (38) of the plant species from which phytoseiid mites were collected had leaves with well-developed coverings of hairs on their abaxial surfaces, especially along the veins. Species in the genus Phytoseius were the most abundant mites (46.4% of total), and they were almost entirely restricted to leaves with well-developed tomenta (714 of 720 Phytoseius mites collected from 34 of 38 plant species with hairy leaves). In a test of these observations at three sites in Victoria, phytoseiid mites in general were more abundant on leaves with well-developed tomenta, but only Phytoseius mites were restricted to hairy leaves.
