Endemic Plants of Lake Van Basin

Abstract

This study was carried out on endemic plants collected from the Lake Van basin between 1994 and 2002. As a result, 98 endemic taxa, 23 of which grow only in the Lake Van basin, were determined. Including the endemic taxa reported before from the region, a list of 259 endemic taxa belonging to 34 families and 117 genera were compiled. Twenty-three of 259 taxa listed, are unique to the Lake Van Basin. There are 249 endemic taxa in the VANF Herbarium. The authors collected 98 of them. The other 151 endemic taxa were determined by other researchers. Ten endemic taxa were recorded from the literature. In addition to the features in the Flora of Turkey, new features and variations of nine endemic taxa identified. Total 612 images and 200 pictures belonging to 98 endemic taxa scanned and transferred to computer. All images were uploaded to the web page, Virtual Herbarium of the Lake Van Basin, which is also a part of VANF Herbarium.

A morphometric study on Draba cappadocica Boiss. & Balansa and Draba rosularis Boiss

“…Field studies were carried out between the years 1997-2001, especially during 4th, 5th and 6th months, and minimum 10 plant specimens were collected for each species from different localities, 7 times for D. rosularis, and 2 times for D. cappadocica (Demirkuş et al, 2000). D. rosularis samples were collected from the localities around the fountain in Güzeldere Pass (Başkale-Van) for 6 times, and the end of Keşiş Lake, around Güvelek Village for 1.…”

New Floristic Records for B8 Square from Perisuyu Valley (YedisuKarlıova / Bingöl)

“…Araştırma alanında belirlenen Endemik bitkilerin risk sınıfları [Ekim et al (2000); Duran et al (2003); Kandemir et al (2015); Armağan (2016) ve IUCN (2017)] Table 1. Risk categories of endemic plants determined in the research area [Ekim et al (2000); Duran et al (2003); Kandemir et al (2015); Armağan (2016) Bugüne kadar B9 (Bitlis ve Van) karesinde yayılışı bilinen (Pimenov, Kljuykov & Degtjareva (2011); Demirkuş, Koyuncu & Gül (2018)) bu bitkinin yayılışının B8 karesinde de tespit edilmiş olması ile yayılış alanının daha geniş olduğu anlaşılmıştır.…”

“…Bu türün risk kategorisi yakın zamanda değerlendirilmiş olup (Demirkuş, Koyuncu & Gül, 2018) tehtide yakın (NT) risk sınıfında yer alması uygun görülmüştür. Bitkinin alanımızda da yayılışının olmasına rağmen halk tarafından tüketiliyor olması (Mükemre et al, 2020) ve düşük düzeyde risk altında olması dikkate alındığında tehdide yakın (NT) risk sınıfında kalması önerilmektedir.…”

Nemrut Krater (Turkey) Gölü’nde Yaşayan Barbus ercisianus (Cypriniformes: Cyprinidae) Balık Türünde Ligula intestinalis (Cestoda: Pseudophyllidea)‘in İlk Bildirimi

“…This leads to unsuitable aquaculture conditions and, consequently, increased susceptibility to infections (Sakai, 1999). The Van Lake Basin, a closed basin, is rich in both plant and animal species (Şekercioğlu et al, 2011;Elp et al, 2016;Adızel et al, 2017;Demirkuş et al, 2018;Toyran et al, 2018). Also, there are many ponds and streams in the basin such as natural lakes of Van, Erçek, Nazik, Nemrut, Aygır, Arin and the dam lakes of Sarımehmet, Koçköprü, Zenek, Morgedik (Cetinkaya, 1993).…”
