Öğe Argyroneta aquatica (Clerck, 1757) (Aranea: Cybaeidae) as a biological indicator for environmental pollution of Sultan Marsh National park, Turkey(Bulgarian Academy of Sciences, 2010) Seyyar O.; Demir H.; Kar M.; Duman F.Sultan Marsh (Turkey) is one of the largest wetland of the Middle East and Europe. The marsh was designated as a Ramsar Site, a Nature Conservation Area, and recently a National Park by Turkish Government. Despite its strong conservation status, the marsh has undergone rapid degradation in recent years. However, major changes have been observed in Sultan Marsh in the last two decades. The water spider, Argyroneta aquatica (Clerck, 1757), was lastly observed in 2000 in the region. Since then, this species has not been observed in the marsh. Increased of pollution in Sultan Marsh is the most probable cause for lacking the species. It may be argued that the water spider can be used as an ecological indicator to determine environmental changes.Öğe Diversity and conservation of endemic spiders (Arachnida: Araneae) in Turkey(Nobel Science and Research Center, 2017) Seyyar O.; Demir H.; Emini A.The endemic spider in Turkey comprises 155 species belongs to 22 families, it represents nearly 14 % of all spider of Turkey. The largest number of endemic species is found in the Dysderidae with 41 species. Also, Leptonetidae and Hersiliidae are 100% endemic. The genus Harpactea which has the highest endemism with 23 species. The largest number of endemic species is distributed in BR and MER in Turkey. Most part of the endemic species in Turkey were distributed mainly in caves. Some remarks on Conservation of Endemic Spiders were also added.Öğe Mimetus laevigatus (keyserling, 1863), a species new for the araneofauna of turkey (araneae, mimetidae)(2005) Topçu A.; Babaşoğlu A.; Kunt K.B.; Demir H.; Seyyar O.[No abstract available]
