DOI: http://dx.doi.org/10.3372/wi.45.45102 Despite more than two centuries of almost uninterrupted surveys and studies of Algerian lichenology, the history and lichen diversity of Algeria are still poorly understood. During the preparation of a forthcoming checklist of Algerian lichens it was considered necessary to provide the present historical overview of lichenological exploration of the country from 1799 to 2013, supported by a reasonably comprehensive annotated bibliography of 171 titles.

Introduction By their ability to thrive in a wide, often extreme variety of habitats, lichens provide a rich mosaic of colour and play an important role in ecosystems. These composite organisms, the product of a successful alliance between a fungus and an alga and/or a cyanobacterium, form a signiicant part of biological biodiversity. Currently it is conservatively estimated that there are 20 000 lichenized and lichenicolous fungi worldwide (Feuerer & Hawksworth 2007), but this number is steadily growing with the intensiication of research on these interesting organisms and the exploration of geographic areas hitherto not or only poorly studied. Although lichens are more noticeable in hot and cold deserts, high altitudes, tundra zones, seashores and even in unpolluted urban areas, their worldwide occurrence and ecological importance cannot be underestimated, since they: (1) enrich the environment by providing moisture, energy, carbon and phosphorus, as well as nitrogen in the case of nitrogen-ixing species; (2) participate in soil formation and stabilization by means of physico-chemical weathering of rocks and their ability to aggregate soil particles; (3) provide a food resource for invertebrates and some vertebrates; and (4) provide habitats and shelter for insects and a source of nest-building material for many birds. Lichens have often been neglected in the past, but in recent decades they have been the subject of renewed interest from the scientiic community. Unfortunately, for Algeria, where the territory has been largely underexplored and would undoubtedly contain many new spe- 1 Laboratoire de Biologie du Sol, Faculté des Sciences Biologiques, Université des Sciences et de la Technologie Houari Boumediène, BP 32 El Alia, Alger 16111, Algeria; e-mail: said_amrani@yahoo.com; asma2n@gmail.com 2 School of Life Sciences, University of Bradford, Bradford BD7 1DP, United Kingdom; *e-mail: m.r.d.seaward@bradford.ac.uk (author for correspondence). 16 Amrani & al.: Lichenological exploration of Algeria cies to discover, work on lichen diversity has aroused little interest among Algerian scientists. In an attempt to provide a new impetus to lichenological research in Algeria, which has sufered from the absence of a recent lichen lora, catalogue or even a checklist, we are currently compiling a checklist from a wide range of sources, particularly published ones. During our researches we thought it necessary in the irst instance to publish a historical overview and an annotated bibliography relating to an appreciable body of knowledge that already exists on Algerian lichens. This list of references is by no means exhaustive, but does include primary sources of published material; a complementary list of titles will accompany the Checklist of Algerian li­ chens currently in preparation. Historical overview of lichenological exploration of Algeria 18th and 19th centuries The study of lichens of Algeria is a relatively old activity dating back to the irst written contribution in 1799 by René Desfontaines Fig. 1.

In less than 25 years, Nylander published ive contributions dealing more or less with Algerian lichens, two of which are of particular importance. In his Études sur les lichens de l ’Algérie, Nylander (1854) listed 167 taxa, including 141 attributed to Durieu de Maisonneuve (see above), and Symbolae quaedam ad lichenographiam sahariensem (Nylander 1878), concentrating mainly on lichens of desert areas of Algeria, where he enumerated c. 50 species, including 17 new to science. He also published Lichenes algerienses novi (Nylander 1853) and integrated the Algerian lichens hitherto known in his Prodromus lichenographiae Galliae et Algeriae (Nylander 1858b). The early 1890s saw the emergence of the works of one of the scientists who contributed the most to Algerian lichenology, namely Camille Flagey (1837 – 1898). Established as a civil engineer in 1884 in Constantine (E Algeria), he studied the lichens, mainly of that area, for 15 years, his irst published contribution being Herbori­ sation lichénologique dans les environs de Constantine (Algérie) (Flagey 1888). He is better known for his three fascicles of exsiccatae (Flagey 1891a – b, 1892, 1895) and his Catalogue des lichens d’Algérie (Flagey 1896) published as part of Flore de l’Algérie. For his catalogue, Flagey drew on his own observations, mainly in the region of Constantine, and on those of Montagne; he also duly acknowledged the support of Nylander, Ferdinand Arnold (1828 – 1901) and Ernst Stizenberger (1827 – 1895) in its compilation. In doing so, he increased the number of lichen taxa for Algeria from the 180 recognized by Montagne to almost 650. Flagey’s catalogue has remained to this day the most comprehensive compilation of Algerian lichens. Almost simultaneously with the publication of Flagey’s catalogue, Julius Steiner (1844 – 1918) published two important contributions on Algerian lichens, namely Ein Beitrag zur Flechtenlora der Sahara (Steiner 1895), which lists 18 taxa, including four species new to science, and Zweiter Beitrag zur Flechtenlora Algiers (Steiner 1902), which lists 60 taxa, including a new genus, Gono­ hymenia J. Steiner, and 11 species new to science. 20th century In addition to Steiner (1902), the irst half of the 20th century saw the publication of a large number of contributions on Algerian lichens (Gandoger 1883; Zahlbruckner 1904; Flahault 1906; Maheu 1906; Bouly de Lesdain 1907, 1909, 1911, 1939; Lapie 1909; Battandier & al. 1914; Maire 1916, 1933; Hue 1921; Tits 1925; Maire & 17 Senevet 1928; Szatala 1929; Andreanszky 1934; Maire & Wilczek 1935; Werner 1939, 1941, 1949; Dubuis & Faurel 1945). Almost all of these contributions were based on explorations of limited or small geographic areas, but some included the discovery of several new lichen species. Among these reports, the contribution of Bénédict Hochreutiner (1873 – 1959) should be highlighted; the lichens he collected from Algeria in 1901, including a new species, Physcia hochreutineri Zahlbr., were identiied by Alexander Zahlbruckner (1860 – 1938); see Zahlbruckner in Hochreutiner (1904). In the same period, Roger-Guy Werner (1901 – 1977), although involved primarily in a study of North African lichens, particularly those of Morocco, added considerably to our knowledge of Algerian lichens through his phytogeographical analyses of the region, including four that were more closely related to Algeria (Werner 1939, 1941, 1949, 1956). The second half of the 20th century saw the publication of an even larger number of contributions of quantitative and qualitative importance (Faurel & al. 1951a, b, 1952, 1953a – c, 1954; Faurel & Schotter 1954; Collenot & al. 1960; Werner 1975; Schwarz 1976; Semadi 1983, 1989; Esnault 1985; Esnault & Roux 1987; Egea 1989; Zouaoui 1989; Egea & al. 1990; Haluwyn & LetrouitGalinou 1990; Haluwyn & al. 1994). Of these contributions, it is important to highlight those of Faurel & al. (1951a, 1953a, 1954), published under the title of “Matériaux pour la lore lichénologique d’Algérie et de Tunisie”, which attempted to lay the foundation for a true lichen lora of Algeria and Tunisia, a project seemingly impaired by the Algerian War of Independence (1954 – 1962). Following that conlict, 13 years elapsed before the publication of contributions dealing with Algerian lichens, the irst of which was that of Werner (1975) based on his examination of six lichens collected by René Maire (1878 – 1959), including Lecanora chlarotera Nyl., new to the country. This contribution was quickly followed by that of Schwarz (1976), who undertook a lichenological survey in the mountains of the desert area of Tamanrasset (D11) and found c. 20 taxa, all of which were previously known from Algeria. The irst contributions by an Algerian researcher to our knowledge of Algerian lichens were undertaken by Semadi (1983, 1989) within the framework of his doctorate theses. In both contributions he surveyed lichens in the area of Annaba (D25), from where he reported 88 taxa. Another important Algerian contribution was provided by Zouaoui (1989) within the framework of his master’s thesis on the lichens of the Akfadou and Beni-Ghobri forests (D15 & D9), in which he lists 147 taxa, 66 of them new to Algeria. These proved to be the exception during the period 1980 – 2000, as other important published contributions on Algerian lichens resulted mainly from the work of foreign lichenologists, particularly those of French and Spanish origin. The irst and most important French contribution was the doctorate thesis of Esnault 18 (1985), which concentrated on the genus Aspicilia A. Massal. in Algeria. In this thesis, Esnault enumerated 39 Aspicilia taxa (34 named and four considered new to science), of which 24 were new to Algeria and 17 were new to North Africa; resulting from this work one year later was the description of Amygdalaria tellensis Esnault & Cl. Roux, new to science (Esnault & Roux 1987). Other French contributions from this period were those of the van Haluwyn group (Haluwyn & Letrouit-Galinou 1990; Haluwyn & al. 1994) undertaken in NE Algeria, the latter including Waynea stoechadiana (Abassi & Cl. Roux) Cl. Roux & P. Clerc, a species new to Africa. However, two contributions by Algerians on the lichen lora of the industrial area centred on Annaba (D23) were also published during this period (Semadi & Tahar 1995; Semadi & al. 1997). 21st century Since the beginning of this century, about 25 published contributions and theses on the biodiversity of Algerian lichens have appeared. The irst and most important ones were those of Alonso & Egea (2003) and Rahali (2003), which enumerated respectively 74 and 62 species, all probably already known from Algeria. The most recent publications on Algerian lichens have resulted from the work of Algerian teams (Fadel & al. 2010; Ait Hammou & al. 2011; Rebbas & al. 2011; Serradj & al. 2013; Slimani & al. 2013), all of whom, unfortunately, studied previously explored areas and did not lead to the discovery of species new to science, or indeed new to Algeria. Besides those authors who have explored Algeria irst-hand in search of lichens or who have investigated specimens provided by other collectors, one must not forget those who have contributed to our knowledge by their meticulous investigation of herbarium specimens. For example, Navarro-Rosinés & al. (2000) assigned an Algerian specimen from the Werner Herbarium to a new species, Caloplaca calcitrapa Nav.-Ros. & al., and Rico & al. (2007) assigned Algerian material from the Esnault Herbarium to Aspicilia uxoris (Werner) V. J. Rico & al., a new combination for a species known from Algeria, Morocco and Spain. Similarly, one should not forget those authors who, although not directly involved in the study of Algerian lichens, have included them in their works (e.g. Hue 1890, 1891, 1892, 1898, 1899, 1900, 1901; Harmand 1905a, b, 1907, 1909, 1913; Ozenda & Clauzade 1970; Vouaux 1912, 1914). Further considerations Despite the numerous lichen surveys of, and collections from, Algeria before and after independence, there is no oicial lichen herbarium to support lichenological research within Algeria. Unfortunately, those herbaria (e.g. Faurel, Flagey, Maire) established during the colonial period, and stored at the Faculty of Sciences of Amrani & al.: Lichenological exploration of Algeria Algiers, were all transferred to France before independence and this material is to be found in several herbaria (e.g. MARS, MPU, P, STR – codes according to Thiers 2014+). Furthermore, as regards the collections made in surveys carried out since independence, voucher specimens for detailed study by foreign lichenologists are currently housed in institutional herbaria (e.g. Egea and his research group in MUB) or personal herbaria (e.g. Esnault, van Haluwyn, Letrouit-Galinou), not all easily accessible. Furthermore, in the absence of a national repository, Algerian lichenologists retain personal herbaria that are not necessarily accessible, and their quality and sustainability cannot be guaranteed. A national herbarium in Algeria is clearly a prerequisite to support future lichenological research in the country. As elsewhere in the world, lichen diversity in Algeria is threatened mainly by pollution, reduction in natural habitats, and climate change. A further threat is intensive harvesting of marketable species, such as Pseudevernia furfuracea (L.) Zopf, which is used as a spice for cooking, as a perfume base for several cosmetic preparations, or as a substitute for incense. To protect such lichens, Algeria has enacted a law prohibiting the unauthorized collection of about 100 taxa (RADP 2012). Perhaps one of the reasons for the limited knowledge of Algerian lichens by the international scientiic community is that the vast majority of contributions before and after independence have been written in French rather than English. It is clear from our literature survey that, whatever the period considered, most of the studies undertaken on Algerian lichens have led to the discovery of species which, if not new to science, are at least new to Algeria. Such discoveries lead one to believe that Algeria is rather poorly explored from a lichenological point of view and almost certainly contains many lichen taxa yet to be discovered. We trust that this brief historical review and comprehensive annotated bibliography, together with the forthcoming Checklist of Algerian lichens, will encourage scientists to investigate an important component of Algeria’s biodiversity and to make it better known to the world’s scientiic community.
