The first mountain we surveyed during our recent expedition in Turkey was the 2500-m high Honaz. When we first reached the peak in our van, it was cool and rainy. Soon the clouds started to disperse; we could begin to see thru mist the vast scenery below us.
Our first station was right below the peak at 2510 m. At that altitude we could find only one tiny species of snail: Gallandia annularis. Their shells barely reach 4 mm in diameter.
The range of this species extends from the Iberian Peninsula thru the Alps, the Crimea, Turkey to Afghanistan (Hausdorf. 1995. Zool. Anz. 234:63). It is always found in mountainous areas. Widespread species like G. annularis with restricted habitats always raise the same question: how do they get from one suitable habitat to another?
