Türkiye, Campanula cinsi çeşitliliği bakımından Akdeniz Havzası’ndaki en zengin ülkelerinden biridir ve Türkiye türlerinin yarısından fazlası endemiktir. Bu yazıda C. cymbalaria var. papillosa (Campanulaceae) Türkiye’den yeni bir varyete olarak tanımlanmaktadır. Varyetenin ayırt edici karakterleri, tam betimi kapsamlı fotoğrafları verilmiştir. Morfolojik özelliklerine göre subgen. sect. Saxicol...

Recent phylogenetic works have begun to address long-standing questions regarding the systematics of Campanula (Campanulaceae). Yet, aspects of the evolutionary history, particularly in northwestern North America, remain unresolved. Thus, our primary goal in this study was to infer the phylogenetic positions of northwestern Campanula species within the greater Campanuloideae tree. We combined n...

Oligolectic bees collect pollen from a few plants within a genus or family to rear their offspring, and are known to rely on visual and olfactory floral cues to recognize host plants. However, studies investigating whether oligolectic bees recognize distinct host plants by using shared floral cues are scarce. In the present study, we investigated in a comparative approach the visual and olfacto...

Evolutionary trees of species can be reconstructed by pairwise comparison of their entire genomes. Such a comparison can be quantified by determining the number of events that change the order of genes in a genome. Earlier Erdem and Tillier formulated the pairwise comparison of entire genomes as the problem of planning rearrangement events that transform one genome to the other. We reformulate ...
