Türkiye'nin Bazı Herbaryumlarındaki Salicaceae Koleksiyonu Verilerinin Analizi

Abstract

Building on centuries of research based on herbarium specimens gathered through time and around the world, much research on the analysis of collections data in the herbarium is being done. In this study, it was analyzed the herbarium sheets from the family Salicaceae. According to the herbarium records examined, Salicaceae family is represented by two genera in Turkish herbariums. A collection of 917 herbarium records for the genus Salix and 242 for the genus Populus was considered from the six biggest herbaria of Türkiye as ANK, ISTO, HUB, AEF, ISTE and GAZI. The number of taxa in herbaria collections, distribution, and the number of taxa according to family, distribution of taxa by collection date and locations, and comparison of Turkish data with well-known herbaria from the world were evaluated in the current study. Python programming language was applied for the data cleaning and visualization using pie charts, plots, bar graphs and map plots. ISTO holds most of the genus Salix with 287 records, followed by AEF with 221 records and HUB with 148 records. Total genus Salix collections of herbaria include 53 taxa. The oldest Salix herbarium sheet dates back to the mid-1800s (GAZI), whereas most herbarium sheets were collected from 2000-2001 (AEF). Most records for both genera Salix/Populus, were collected from Ankara province. It is followed by Bolu and Kars districts, respectively. Furthermore, the locations from which the Salicaceae members have been collected are presented with the help of a Turkish province map.
