Özet
Bu çalışmada Sünnet Gölü çevresinin (Bolu, Türkiye) damarlı bitki gamma-çeşitliliği araştırılmıştır. Alanın damarlı bitki florası 2006 ve 2009 yılları arasında yapılan arazi çalışmaları sonucu tespit edilmiştir. Çalışma sonucu 67 familya ve 216 cinse ait 324 takson kaydedilmiştir. Alanda tespit edilen endemik türlerin sayısı 35, endemizim oranı ise %10.8 olmuştur. En zengin familyalar Lamiaceae, Asteraceae, Fabaceae, Boraginaceae ve Rosaceae"dır. En büyük cinsler ise Astragalus, Vicia, Salvia, Centaurea ve Viola olmuştur. Türlerin fitocoğrafik alanlara göre dağılımı ise %16.4 Avrupa-Sibirya (Öksin alanını içerecek şekilde), %13.3 Akdeniz ve %10.2 Iran-Turan elementi şeklinde olmuştur. Çalışma alanının floristik bileşimi 11 farklı komşu alanla karşılaştırılmıştır. TWINSPAN analizi karşılaştırılan 12 alanı dört ana komünite tipi altında sınıflandırmıştır. Detrended Correspondence Analizi (DCA), alanları üç farklı küme ve Gökçeler Dağı şeklinde gruplandırmıştır. UPGMA küme analizi sonucu Gökçeler Dağı haricindeki diğer alanlar iki küme altında toplanmıştır.
This paper reports the gamma-diversity of vascular plant taxa (ferns, fern allies and seed plants) of the surrounding of Lake Sünnet (Bolu, Turkey). The vascular flora of the surrounding of Lake Sünnet was compiled from the fieldworks done between 2006 and 2009. The studies resulted in 324 taxa belonging to 67 families and 216 genera. The number of endemic species was found to be 35, corresponding to an endemism ratio of 10.8%. The richest families were Lamiaceae, Asteraceae, Fabaceae, Boraginaceae, and Rosaceae. The richest genera were found as Astragalus, Vicia, Salvia, Centaurea, and Viola. Distribution of the species according to phytogeographical regions resulted in 16.4% as Euro-Siberian elements (including Euxines), 13.3% as Mediterranean elements, and 10.2% as Irano-Turanian elements. The study site was compared with floristic composition of 11 other neighboring regions. TWINSPAN analysis classified 12 sites into four main community types. Detrended Correspondence Analysis (DCA) resulted in three clusters and Gökçeler Mountain. In UPGMA cluster analysis there are two clusters and Gökçeler Mountain was also placed separately.
