Anders Langangen Charophytes (Charales) from Samos and Ikaria (Greece) Collected in 2013 and Report on Some Localities in Skiath
Fl. Medit. 24: 139-151 doi: 10.7320/FlMedit24.139 Version of Record published online on 30 December 2014 Anders Langangen Charophytes (Charales) from Samos and Ikaria (Greece) collected in 2013 and report on some localities in Skiathos (Greece) Abstract Langangen, A.: Charophytes (Charales) from Samos and Ikaria (Greece) collected in 2013 and report on some localities in Skiathos (Greece). — Fl. Medit. 24: 139-151. 2014. — ISSN: 1120- 4052 printed, 2240-4538 online. In 2013 three Greek islands, Samos, Ikaria and Skiathos were visited. Charophytes were found in Samos and Ikaria but not in Skiathos. Out of 23 visited localities charophytes were found in 12. Seven species of charophytes were found in Samos (Lamprothamnium papulosum, Chara canescens, C. vul- garis, C. gymnophylla, C. corfuensis, Tolypella nidifica and T. glomereta) and in Ikaria one species (Chara vulgaris). Species richness in Samos is due to a variety of different habitats including brack- ish water lakes, running brackish water, fresh water pools and slowly moving rivers. Key words: Tolypella nidifica, T. glomerata, Lamprothamnium papulosum, Chara canescens, C, vulgaris, C. gymnophylla, C. corfuensis. Introduction Samos and Ikaria are the two southernmost islands of the Northeast Agean Islands. Several water bodies including lakes, reservoirs, brackish water, brooks and springs were visited. Localities with charophytes are listed in Table 1 and localities without charophytes in Table 2. Skiathos, an island in the Northern Sporades, where no charophytes were found, was also visited. Materials and methods This work is based on material collected in the localities on Samos and Ikaria in May (Fig. 1) and Skiathos in September 2013.

The first charophyte collection in this region was made in the 19th century. Almost all reported localities were found earlier than 1970; some of them were not described. At the end of the 20th century, only two localities of two species were reported. According to the literature, 13 species, including two undetermined species of Chara, and nearly 23 exact localities are known from Northern and Central Israel. We found seven species and one variety of charophytes in 23 new localities in eight river drainage basins from six ecological regions of Israel during the period extending from 2001-2011. One genus ñ Tolypella, and two species ñ Chara intermedia and Tolypella glomerata, were found for the first time in Israel. There are 15 species and four genera of charophytes known from the studied territory based on published and original data. The common habitats of charophytes in Israel are river channels, pools, and, especially, artificial water bodies. The Chara vulgaris var. longibracteata, C. gymnophylla and C. contraria are the most frequently encountered species.

Duringthe last year, we had a very nice and interesting GEC meeting, excellently organized in Valencia by Maria Rodrigo, with the help of Carmen Rojo, Sara Calero, Eric Puche, and Mati Segura. Many thanks to all the organizers, for the fantastic location, the perfect organization, the very nice food and the interesting field trips! Our organization is small but very active, and this means we have already plans for the forthcoming three meetings. These will be: (1) a GEC meeting in September 2018, inSicily (you will find more information about it in this issue of the News). (2) Then we will have an IRGC meeting in March 2020, in Tunisia: more information is available in this issue of the News. Please note that – contrary to what was our usual practice, the IRGC meeting will be held in March! The reason is the warm and dry summer in Tunisia, which generally causes the smaller water bodies (containing charophytes) to dry out.

The Worldwide Range of the Charophyte Species Native to Germany
Rostock. Meeresbiolog. Beitr. Heft 28 45-96 Rostock 2018 Heiko KORSCH* * Schillbachstraße 19, 07743 Jena [email protected] The worldwide range of the Charophyte species native to Germany Abstract Based on extensive evaluations, the worldwide distributions of the 36 Charophyte species native to Germany are presented. Some of these species are distributed almost worldwide (e.g. Chara braunii, C. vulgaris, Nitella hyalina), while others have much smaller ranges. Chara filiformis for example is restricted to a small part of continental Europe. For many species comments are made to explain the species concept used or to give hints about doubtful data. Keywords: Plant geography, Characeae, Charophytes, range-maps, Chara, Lamprothamnium, Lychnothamnus, Nitella, Nitellopsis, Tolypella Zusammenfassung: Areale der in Deutschland heimischen Characeen-Arten. Auf der Grundlage umfangreicher Recherchen werden die weltweiten Areale der in Deutschland vorkommenden 36 Characeen-Arten dargestellt. Von diesen Arten sind einige (z. B. Chara braunii, C. vulgaris, Nitella hyalina) fast weltweit verbreitet, andere haben deutlich kleinere Areale. So ist z. B. Chara filiformis auf kleine Teile Europas beschränkt. Zu einer ganzen Reihe von Arten werden Kommentare geben. Diese erläutern die verwendeten Artumgrenzungen oder geben Hinweise zu fraglichen Angaben. 1 Introduction In recent decades and after a phase of stagnation in Germany, interest in the Characeae has markedly increased. The Habitats Directive 92/43/EC (EC1992) and the Water Framework Directive 2000/60/EC (EC 2000) of the European Union have intensified this process. Because of their size and their complex structure, the Charophytes are morphologically clearly distinguished from most other groups of Algae. The results of genetic investigations show that they are more closely related to the Mosses and higher plants rather than to the other algae (QUI 2008).

Some Charophyta (Charales) from Coastal Temporary Ponds in Velipoja Area (North Albania)
Journal of Environmental Science and Engineering B 5 (2016) 69-77 doi:10.17265/2162-5263/2016.02.002 D DAVID PUBLISHING Some Charophyta (Charales) from Coastal Temporary Ponds in Velipoja Area (North Albania) Vilza Zeneli1 and Lefter Kashta2 1. Department of Biology, Faculty of Natural Sciences, The University of Tirana, Tirana 1001, Albania 2. Research Center of Flora and Fauna, Faculty of Natural Sciences, The University of Tirana, Tirana 1001, Albania Abstract: Charophytes or stoneworts constitute a group of macrophytes that occur mostly in fresh-water environments but can also be found in brackish waters. Knowledge about stoneworts in Albania is still scarce and incomplete. According to published data on charoflora of Albania, there are 24 species and four genera known from different freshwater habitats. The present work is based on plant material sampled from 5 slightly brackish-water temporary ponds in the coastal area of Velipoja (north Albania). During spring and summer of 2013-2015, field surveys were carried out with the main purpose of filling knowledge gaps concerning brackish water charophytes. Altogether seven species were identified: four typical of brackish water habitat (Chara baltica, Chara canescens, Chara galioides and Chara connivens) and three of broader tolerance (Chara aspera, Chara vulgaris and Tolypella glomerata). The first three species, which considered as the rarest and most threatened on the Balkans were found for the first time in Albania. Key words: Charophyta, brackish water, Albania, Velipoja area, temporary ponds. 1. Introduction (one species) and Tolypella (one species) were reported for Albania from different freshwater habitats Charophytes or stoneworts are a group of like lakes, rivers, ponds, etc.

Joint Nature Conservation Committee, Peterborough. © Joint Nature Conservation Committee 2020 Guidelines for the Selection of Biological SSSIs – Part 2: Chapter 15 Charophytes (Stoneworts) Cover note This chapter is the final element of the Guidelines that supersede Chapter 12 of Guidelines for selection of biological SSSIs concerning non-vascular plants (Hodgetts 1992). Following the provision of separate Guidelines for fungi, bryophytes and lichens (Chapters 12-14), this chapter now covers only charophytes. In future other groups of freshwater algae may be added if information is available. This chapter was prepared by Tristan Hatton-Ellis (Natural Resources Wales), Ian Taylor (Natural England), Ewan Lawrie (NatureScot) and Christine Maggs (JNCC), with helpful input from Sam Bosanquet (NRW) and Ruth Hall (NE). It provides detailed guidance for use in selecting sites for charophytes (stoneworts) throughout Great Britain to recommend for notification as SSSIs. The chapter should be used in conjunction with Part 1 of the SSSI Selection Guidelines (Bainbridge et al. 2013), which details the overarching rationale, operational approach and criteria for selection of SSSIs.

Cryptogamie, Algologie, 2012, 33 (4): 359-390 © 2012 Adac. Tous droits réservés Some Charophytes (Characeae, Charophyta) from central and western of Iran including Chara kohrangiana species nova Akram AHMADI a*, Hossein RIAHI a, Masoud SHEIDAI a & Joop VAN RAAM† a Faculty of Biological Sciences, Shahid Beheshti University, Evin, Tehran, P.O.Box 1983963113, Iran Abstract – Stoneworts are a conserved group within green algae which usually inhabit in submerged conditions of slow running and standing water. Charales is a difficult taxono- mical group regarding species identification. This paper records 13 species of charophytes within three genera found in about eighty localities from Iran. The taxa Chara connivens, C. contraria, C. crassicaulis, C. fibrosa, C. grovesii, C. gymnophylla (two varieties C. gymno- phylla var. gymnophylla and C. gymnophylla var. rohlenae), C. kirghisorum, C. pedunculata, C. socotrensioides, C. tomentosa, C. vulgaris (C. vulgaris var. longibracteata and C. vulgaris var. vulgaris), Nitella hyalina and Tolypella glomerata were studied, including vegetative and oospore characteristics of them. C. vulgaris and C. gymnophylla, are the most common species. The species C. kohrangiana is proposed as a new monoecious species characterized by stipulodes developed in one row, anterior and posterior bract-cells, ecorticate branchlets and diplostichous incomplete axial cortex. C. kohrangiana belongs to subgenus Charopsis section Agardhia subsection Agardhia. Charophytes / Chara / Nitella / Tolypella / Chara kohrangiana / determination / taxonomy Résumé – Les Charales constituent un groupe ancien au sein des algues vertes qui se trouve généralement submergées dans des eaux calmes ou stagnantes. L’identification des espèces de cet ordre est une tache le plus souvent difficile.
