Lichen: from genome to ecosystem in a changing world 1A-P (1A-P9) Submission ID: IAL0129-00002 ARID LICHENS FROM THE RED DATA BOOK OF UKRAINE - ASSESSMENT, CONSERVATION AND PERSPECTIVES Nadyeina O.

Kholodny Institute of Botany, Kyiv, Ukraine 2 Botany, Kherson State University, Kherson, Ukraine 3 Botany, I. I. Mechnykov Odessa National University, Odessa, Ukraine A project supported by Rufford SGF was carried out in Ukraine during 2009-2011 and combined lichen floristics and community ecology. Our focus was on arid terricolous lichens in steppes because these ecosystems occupy an important part of the Ukrainian territory. However, steppe ecosystems are amongst the most disturbed areas, affected by built-up areas, mines, industries, crop farming and overgrazing. The main aim of this study was to disseminate knowledge about steppe lichens and their conservation biology to the local population, governmental and regional administrations, staff of protected areas, etc. Our activity included monitoring of terricolous lichen communities and species distribution in Ukrainian steppes. We have prepared and distributed a brochure “What do you know about steppe lichens–minute world under your foot” to school associations of young biologists and ecologists, biological faculties of universities from the main regions, administration of protected areas and Ministry of Natural Protection. Eight months later we have already received lichen specimens from schools and social organizations; also some local children`s and historic-cultural journals were interested in our project. From a scientific point of view we have collected data about historic and modern localities of terricolous lichens with relations to the steppe zone of Ukraine, including 11 species from the present edition of Red Data Book of Ukraine (2009): Agrestia hispida, Aspicilia fruticulosa, A. vagans, Cetraria steppae, Fulgensia desertorum, Leptogium schraderi, Seirophora lacunosa, Squamarina lentigera, Xanthoparmelia camtschadalis, X. ryssolea. We documented localities for 10 redlisted species, some as new, others to reconfirm records from the 19 th century. In this project we described associations of terricolous lichens and clarified some taxonomically difficult species, as Cetraria steppae and Xanthoparmelia ryssolea. Our field trips and collaborations with other organizations and colleagues stimulated the establishment of new protected areas in the south of Ukraine, notably in Kherson, Donetsk, Luhansk, Odessa regions and Crimea. We assume that popularization of the lichen conservation issue will also influence the acceptance of local and regional administrations for lichen conservation. 86
The 7 th International Association for Lichenology Symposium 2012 (1A-P10) Submission ID: IAL0138-00001 CAUCASUS BIOSPHERE RESERVE (WESTERN CAUCASUS, RUSSIA) AS A POTENTIAL VALUABLE HOTSPOT OF LICHEN DIVERSITY IN CAUCASUS AND RUSSIA Urbanavichyus G. P. 1 , Urbanavichene I. 2 1 Laboratory of Terrestrial Ecosystems, Institute of The Industrial Ecology Problems of the North, Russian Academy of Sciences, Apatity, Murmansk, Russia 2 Laboratory of Lichenology and Bryology, Komarov Botanical Institute, Russian Academy of Sciences, Saint-Petersburg, Russia The Caucasus Mountains are one of the world’s biodiversity hotspots as well as one of the richest regions of Russia in this aspect. However, the Caucasus is not recognized yet as a hotspot of lichen species diversity, because the lichen flora of the Caucasus is still incompletely known. There are 1,119 species mentioned for the Northern Caucasus in the Russian lichen checklist (2010), which comprise 33% of total lichen flora of Russia. UNESCO-MAB Caucasus Biosphere Reserve (Kavkazskiy Zapovednik) is situated in the western Caucasus, which is the core of the Western Caucasus World Heritage Site. The area of the Reserve covers about 2,800 sq km of various natural ecosystems, which are about 80% of whole Great Caucasus ecosystem types. There are distinct ecological and altitudinal belts–from subtropics on the eastern Black Sea coast (30 m alt.) up to glacial and nival habitats (3,300-3,360 m alt.), with unique temperate broadleaf and mixed rainforests with annual precipitation over 2,500 mm in the most of western part of the Caucasus. High level of species endemism is character for the whole Caucasus region. Our study report 745 species of lichens and lichenicolous fungi for the Caucasian Biosphere Reserve (more than 100 are additions to the Northern Caucasus list). However our investigations covered only small part of the Reserve. Anyway we state the Caucasus Reserve has one of the richest lichen flora Reserves in Russia as compared to Pechoro-Ilych Reserve (889 sp.); Baikalskiy (719 sp.) and Laplandskiy (612 sp.). More then 130 lichens from the Caucasian Reserve are not known in other Russian Reserves and 430 species are not known in other Reserve areas of Caucasus. Nevertheless, we suppose that the actual number of species is much higher: about 1,200 lichen species could be registrated in the reserve and over 2,500 species for the whole lichen flora of the Caucasus. Therefore the Caucasus Reserve is of critical value for the total Caucasian lichen diversity conservation. The rich lichen diversity in a mountainforested area clearly justifies a more detailed lichen exploration in the region. 87 1A-P
