- The Balıkdamı Wetland, an impoundment of the upper course of the Sakarya River located near Sivrihisar (Eskişehir, Central Anatolia), is one of the most important bird conservation areas in Turkey. This area also encompasses the mouth of the torrential Göksu Stream, which is partly hyporheic. During this study (2001–2003), 1,471 specimens representing 34 taxa of aquatic Oligochaeta were collected from the Balıkdamı Wetland. All the species identified are new records for Balıkdamı. Two species, Coralliodrilus amissus sp. n. and Gianius anatolicus sp. n., are new to science, and five species, Stylodrilus parvus (Hrabě et Černosvitov, 1927), Chaetogaster diastrophus (Gruithuisen, 1828), Peipsidrilus libanus (Giani et al., 1982), Tubifex acuticularis Martinez-Ansemil et Giani, 1983, and Epirodrilus moubayedi Giani et Martinez-Ansemil, 1983, are new records for Turkey. Two other species, Peipsidrilus libanus and Tubifex acuticularis, are re-described. The oligochaete fauna of the wetland was dominated by widely distributed tubificid taxa. The lumbriculid Stylodrilus parvus was the most abundant species in the Göksu stream. The two new phallodriline species are remarkable since most representatives of this subfamily live in the marine environment. Due to the species richness and diversity of Oligochaeta, as well as of several other animal groups, the Balıkdamı wetland area deserves conservation.

Journal article (peer-reviewed)abstract
- The species diversity of Clitellata (a group of annelid worms) is described for three river systems in different parts of southern Sweden. The water of one river (Save (a) over circlen) discharges into the harbour of Goteborg on the Swedish west coast, that of the other two rivers (Svart (a) over circlen and Kila (a) over circlen) into the Baltic Sea. A total of 143 species, representing the taxa Enchytraeidae (61), Propappidae (1), Lumbricidae (15), Lumbriculidae (6), Tubificidae (4 Rhyacodrilinae, 33 Naidinae, 13 Tubificinae), and Hirudinida (10), are reported. Of these, 24 enchytraeids and six lumbricids were found only in the riparian zone, i.e., in the semi-aquatic habitats of the river banks. Six species of Enchytraeidae could not be assigned to any known species and are likely to be new to science. In addition, the following species are recorded from Sweden for the first time : Achaeta brevivasa, Fridericia benti, F. healyae, F. lenta, F. sylvatica, Oconnorella tubifera (all Enchytraeidae), Aporrectodea limicola (Lumbricidae), Stylodrilus brachystylus (Lumbriculidae), Dero dorsalis, Nais behningi, Haber speciosus, and Peipsidrilus ?saamicus (all Tubificidae). Overall, the species composition is typical of today's fauna of the once glaciated Northern Europe, but for the family Enchytraeidae, the biogeographical affinity of Sweden is stronger with Denmark and Germany than with, e.g., the British Isles and the eastern parts of Central Europe.
