Moreover, the ranges of Ugandan land snail species are significantly nested. The nestedness of the land snail fauna might have been caused by range restrictions during the Pleistocene cold ages. The geographic centre of the sets of nested subsets is in the mountains in SW Uganda close to the supposed East-Congolian forest refuge. Differential immigration of species restricted to the refuge during the glacials was probably an important mechanism resulting in the observed nestedness of the ranges of the Ugandan land snail species.

Ecology Research Group, Canterbury Christ Church University, Imperial College at Wye, Wye, Ashford, Kent TN25 5AH, UK, Email: gbd1@cant.ac.uk In recent years, a cooperative project between the Hubei Institute of Schistosomiasis Control and the Tongji Medical College has developed a novel molluscicide (LDS). In order to further understand the effect of this molluscicide, parallel trials were undertaken with both LDS and Niclosamide against Oncomelania hupensis. Application methods included immersion, spraying and powder applications. For immersed snails, mortality was affected by temperature (LDS 0.4mg/l mortality at 20 o C, 25 o C and 30 o C was 96.7%, 100% and 100% respectively). In field trials, immersion in 0.4mg/l for 24, 48h and 72h at temperatures between 15 to 24 o C led to mortality rates of 92%, 100% and 100% for LDS and 60%, 76%, and 96% for Niclosamide. When a spray method of application was investigated in the laboratory, 0.4g/m 2 at 25 o C gave a seven-day mortality rate of 100% for LDS and 96% for Niclosamide. Spraying in the field at temperatures of 15-24 o C and concentration of 0.2g/m 2 , 0.4g/m 2 and 0.8g/m 2 gave a three-day mortality rate of 81.4%, 97.0% and 100% respectively for LDS, and 54%, 87% and 91% respectively for Niclosamide. Powder application in the lab of 0.4g/ m 2 at 25 o C gave seven-day mortality rates of 92% for LDS and 94% for Niclosamide. In the field, powder application at temperatures of 15-24 o C and concentrations of 0.2g/ m 2 , 0.4g/ m 2 and 0.8g/ m 2 gave three-day mortality rates of 70%, 90% and 99% respectively for LDS and 58%, 85% and 90% respectively for Niclosamide. LDS seems to be an interesting contender as a control agent for O.hupensis. The effects on other target snails which are vectors of fascioliasis and African schisotomiasis are under investigation.

Suleyman Demirel University, Faculty of Science and Literature, Isparta, Turkey, Email: kebapci@fef.sdu.edu.tr According to surveys carried on between 1993-2006 of the malacofauna in 13 stations representing Akdağ (1889 m) and its environs (province Isparta), apart from 15 aquatic snails, it has been determined that 40 land snail species (ordo Stylommatophora) are found in the area. Among these species 15 are endemic to Turkey (appr. 38%) and 5 are exclusively endemic to the study area. The 5 narrow endemics, the enid Borlumastus yildirimi (monotypic genus) and all clausiliid taxa to exist in the area (endemic genera Phrygica and Sprattia), reflect the biogeographical isolation from the surrounding heights 246

Suleyman Demirel University, Faculty of Science and Literature, Isparta, Turkey, Email: kebapci@fef.sdu.edu.tr Graecoanatolica, single genus to tribus Graecoanatolicini RADOMAN, 1973, is known to be distributed in two disjunct areas: Macedonia, Greece and Turkey. In central western Anatolia (‘Lakes region’) namely G. pamphylica, G. lacustristurca, G. tenuis, G. kocapinarica, G. conica, G. brevis have previously been reported. However, due to habitat alterations G. conica is now can not be seen, while G. kocapinarica is under serious threat. With this study also a new taxon, G. wilkei, is introduced as new to science.

Akif Ersoy University, Faculty of Education, Burdur, Turkey, Email: sceylan@mehmetakif.edu.tr The lake system in southwestern Turkey is recognizable with high biological diversity and endemism. The two shallow, tectonic lakes interconnected via a channel, Kovada and Eğirdir, are within province Isparta. Lake Eğridir, second largest fresh water lake in Turkey, has a great economical value due to uses for fishery, tourism, irrigation and obtaining drinkable water. Lake Kovada, on the other hand, was announced as a national park and mainly has a recreational value. Discharge of fertilizers and other pollutants, alien introductions, and other linked practices have been seen serious threats to aquatic biota, resulting in the decline and extinction of populations. From the lakes and sources connected to the lakes, totally 8 prosobranch (6 endemics), 14 basommatophoran gastropods (1 endemic), and 3 bivalve taxa haven been determined so far. In the present study, present and past status of the biodiversity of the lakes and threats are summarized. Affiliations of the present status with the populations of mollusks, problems and possible conservative strategies to be followed are discussed. 247
