The saxicolous Homalothecio-Neckeradelphetum menziesii new to western Turkey: phytosociology, ecology and life strategies
Kürschner, Harald; Erdağ, Adnan
A phytosociological analysis of the mountainous limestone areas in western Anatolia reveals a distinct saxicolous community, the Homalothecio sericei-Neckeradelphetum menziesii, first described from the Iberian Peninsula. It is typical for vertical or steep inclined, sheltered, humid, base-rich rocks, wooded cliff ledges, and limestone boulders in the shady understorey of the Pinus nigra forests and woodlands. The high constancy of Syntrichia handelii indicates a geographical East Mediterranean race, vicarious to the West Mediterranean stands.The life form and life strategy analyses carried out reveal that the association is mainly composed of weft-, tail- and fan-forming 'passive' perennial shuttle species and perennial stayers, which are strong competitors under the humid and shady site conditions of the vertical cliffs. Cushion, short turf- and tall turf-forming 'generative' perennial stayers, as well as pauciennial colonists are subordinate and mostly invade from nearby xerophytic communities. They are, however, restricted to the sunny, less inclined rock faces.
