Taxonomic importance of leaf anatomical characters for the genus Alopecurus L. (Poaceae)

Tiller leaf anatomical features of nine Alopecurus species collected from high mountainous areas in Turkey were evaluated in the present study. Detailed leaf anatomical descriptions of the studied taxa and an identification key generated using the anatomical features are given. Clustering and principal coordinate analysis (PCA) methods were applied based on a total of 14 leaf anatomical characters. Anatomical differences between species were detected and anatomical characters of taxonomic interest were identified in this genus. With clustering analyses, a UPGMA tree was obtained to show the relationship between the species studied. Based on the results of PCA, the arrangement of adaxial sclerenchyma cells, the number of adaxial ribs, the number of abaxial sclerenchyma strands, the size of epidermal cells and the number of vascular bundles are designated as the most reliable characters to separate the species

Turkish Thoracic Society early career members task force group's virtual congress notes: European Respiratory Society International Congress 2020

In this article, Early Career Task Force Group members of the Turkish Thoracic Society summarize the European Respiratory Society 2020 virtual congress. Current developments in the field of respiratory diseases were compiled with the addition of sessions specific to coronavirus disease 2019 this year. Almost all of the congress sessions were examined, and the important and striking results of the congress were highlighted. Congress sessions were attended by expert researchers, and the prominent messages of each session were highlighted in short summaries. They were then grouped under relevant titles and ranked in order of meaning and relation. It was finalized by a team of researchersTurkish Thoracic Society (TTS
