  • Seventy Years of Changes in the Abundance of Danish Charophytes
    Freshwater Biology (2013) 58, 1682–1693 doi:10.1111/fwb.12159 Seventy years of changes in the abundance of Danish charophytes LARS BAASTRUP-SPOHR, LARS LØNSMANN IVERSEN, JEPPE DAHL-NIELSEN AND KAJ SAND-JENSEN Freshwater Biological Laboratory, Biological Institute, University of Copenhagen, Hillerød, Denmark SUMMARY 1. Charophytes grow attached to soft bottoms in ponds, streams, lakes and estuaries and are highly threatened throughout Europe according to the national Red Lists. We used Danish studies on fresh- water charophyte distributions conducted around 1940 and repeated measurements during recent years to evaluate the historical development of species richness and dominance patterns. We also tested to what extent historical changes of species abundance in 29 waterbodies were related to landscape features, water quality and species traits. 2. We found that three species of freshwater charophytes (Chara filiformis, Tolypella intricata and Nitella gracilis) have apparently disappeared from Denmark while one species (Chara connivens) has immigrated. National species richness has thus declined from 21 to 19 species. 3. Species abundance based on occurrence in many waterbodies followed a linear rank–log abun- dance relationship both in the historical and the recent studies. The dominance structure was stronger today than historically as common species have become relatively more abundant and uncommon species relatively rarer. 4. Among species traits, perenniality and preference for alkaline waters typical of deep-growing species in large alkaline lakes, a rare contemporary habitat, were significantly related to the historic species decline. Species increasing in abundance had wide tolerances to alkalinity and water nitrogen content. 5. Twenty-nine lakes and ponds studied repeatedly showed a significant decline of mean species richness from 3.4 to 2.4 during the 70 years.

  • 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).

The lake is characterized by limited anthropogenic pressure and forested catchment basin. The study was performed in the vegetative season 2010. The vegetation was studied along transect, using the mid-European Braun-Blanquet method of phytosociological relevés. Additionally, basic physical-chemical parameters were measured, to characterize habitat conditions of the lake. The results of physical-chemical analyses evidenced high water quality, and obtained parameter values were typical for mesotrophy. The vegetation survey revealed that almost 70% of the lake’s bottom was overgrown by vegetation. The transects documented the structure of phy- tolittoral typical for chara-lake and the spatial dominance of charophytes in the studied lake (charophyte meadows reached up to 64% of the phytolittoral area). Charophytes were also defining the maximum depth extent of vegetation in Lake Jasne, reaching 5.6 m. As many as 10 charophyte species were stated: Chara virgata, Ch. aspera, Ch. filiformis, Ch. globularis, Ch. intermedia, Ch.

ABSTRACT We provide for the first time a checklist of charophytes of the British Isles (comprising Great Britain, Ireland, the Isle of Man and the Channel Islands) that includes in the synonymy all the basionyms and all the other names known to us to have been used in the British and Irish literature, and the literature references to all the places of publication of these names. The taxa are all included in one family, Characeae, which is divided into two tribes, five genera and 34 species, plus six extra varieties. One new combination is made: Chara virgata Kütz. var. annulata (Lilj.) N. F. Stewart & J. A. Bryant, comb. nov. INTRODUCTION Although now usually considered to be a distinct phylum of algae (Charophyta), or at least a distinct class (Charophyceae) of the green algae or Chlorophyta, the charophytes, charads or stoneworts were traditionally studied along with vascular plants by 19th Century field naturalists because in their macroscopic dimensions and gross morphology they superficially resembled such plants as Equisetum and Potamogeton. Moreover they can be preserved as herbarium specimens like vascular plants, and are the only algae to be included under the term ‘macrophytes’ by freshwater ecologists. Hence, by little more than historical accident, they are listed alongside vascular plants in BSBI Strategy 2000, which sets out the aims and objectives of the Botanical Society of the British Isles.

  • Re-Establishment Techniques and Transplantations of Charophytes to Support Threatened Species
    plants Review Re-Establishment Techniques and Transplantations of Charophytes to Support Threatened Species Irmgard Blindow 1,*, Maria Carlsson 2 and Klaus van de Weyer 3 1 Biological Station of Hiddensee, University of Greifswald, D-18565 Kloster, Germany 2 County Administration Jönköpings Län, Hamngatan 4, S-551 86 Jönköping, Sweden; [email protected] 3 Lanaplan, Lobbericher Str. 5, D-41334 Nettetal, Germany; [email protected] * Correspondence: [email protected] Abstract: Re-establishment of submerged macrophytes and especially charophyte vegetation is a common aim in lake management. If revegetation does not happen spontaneously, transplantations may be a suitable option. Only rarely have transplantations been used as a tool to support threatened submerged macrophytes and, to a much lesser extent, charophytes. Such actions have to consider species-specific life strategies. K-strategists mainly inhabit permanent habitats, are perennial, have low fertility and poor dispersal ability, but are strong competitors and often form dense vegetation. R-strategists are annual species, inhabit shallow water and/or temporary habitats, and are richly fertile. They disperse easily but are weak competitors. While K-strategists easily can be planted as green biomass taken from another site, rare R-strategists often must be reproduced in cultures before they can be planted on-site. In Sweden, several charophyte species are extremely rare and fail to (re)establish, though apparently suitable habitats are available. Limited dispersal and/or lack of diaspore reservoirs are probable explanations. Transplantations are planned to secure the occurrences Citation: Blindow, I.; Carlsson, M.; of these species in the country.
