A total of 93 species of Hedysarum from diverse biogeographic regions, in particular from southwest Asia, were included in phylogenetic analyses using nuclear (ITS) and plastid DNA sequences (trnL–trnF and matK). Maximum likelihood and Bayesian analyses of combined plastid data retrieved Hedysarum as monophyletic, whereas phylogenetic analyses of the nuclear data inferred Hedysarum as non-monophyletic. In both datasets, Hedysarum comprised three distinct and well-supported clades corresponding t...

Endemism is one of the most important concepts in biogeography and is of high relevance for conservation biology. Nevertheless, our understanding of patterns of endemism is still limited in many regions of high biodiversity. This is also the case for Iran, which is rich in biodiversity and endemism, but there is no up-to-date account of diversity and distribution of its endemic species. In this study, a comprehensive list of all endemic vascular plant species of Iran, their taxonomic composition...

Abstract Biodiversity loss due to human activities has dramatically increased in the last decades, and attempts to protect threatened species should be accelerated. An important contribution towards this goal is to identify areas rich in biodiversity and endemism, where conservation will be most efficacious. Here, we follow this strategy for Iran, which includes large parts of the Irano-Anatolian global biodiversity hotspot, to assess the extent of conservation gaps. Based on nearly 25,000 recor...

Molecular phylogenetic analyses have greatly advanced our understanding of phylogenetic relationships in Orobanchaceae, a model system to study parasitism in angiosperms. As members of this group may lack some genes widely used for phylogenetic analysis and exhibit varying degrees of accelerated base substitution in other genes, relationships among major clades identified previously remain contentious. To improve inferences of phylogenetic relationships in Orobanchaceae, we used two pentatricope...

Centres of endemism and areas of endemism are important biogeographic concepts with high relevance for conservation and evolutionary biology. Turkey is located at the intersection of three global biodiversity hotspots (Mediterranean, Caucasus, Irano-Anatolian) and harbors remarkable levels of plant diversity and endemism. Nevertheless, hotspots of vascular plant endemics have never been identified using formal quantitative approaches in this diverse region. Here, using data on 1102 endemic taxa ...

Distribution areas of narrowly endemic species in the European Alps often coincide with Pleistocene refugia, suggesting that allopatric divergence due to Pleistocene range shifts might have been instrumental in their origin. Here, we infer the phylogenetic position of the locally endemic Doronicum cataractarum testing previous hypotheses with respect to its biogeographic and temporal origin (Tertiary origin with southwest Asian affinities versus possibly Pleistocene origin in the Alps). To this ...

Onobrychis sect. Heliobrychis with ca. 30 species is one of the most species-rich sections of Onobrychis. It comprises predominantly perennials mainly distributed in Iran, Turkey, and Transcaucasia. In order to test the monophyly of the section and as well as its subsections and to clarify interspecific relationships, three non-coding chloroplast sequences and the nuclear ribosomal DNA internal transcribed spacer were employed. Phylogenetic analyses were performed by maximum parsimony, maximum l...
