“…In cloudy high altitude subalpine forests of Costa Rica it can form extensive carpets and small hummocks in small mires on shallow peat, but occurs more commonly around the margins of moraine lakes [ 43 , 44 ]. In the northern Andes, it occurs partly in nutrient poor mires with underlying peat, but it also grows directly on the bedrock or on non-organic soils, with little or no peat accumulation, and sometimes as extensive carpets on vertical cliff faces [ 50 , 51 ].…”

Spatial Genetic Structure of the Abundant and Widespread Peatmoss Sphagnum magellanicum Brid.

Spore-producing organisms have small dispersal units enabling them to become widespread across continents. However, barriers to gene flow and cryptic speciation may exist. The common, haploid peatmoss Sphagnum magellanicum occurs in both the Northern and Southern hemisphere, and is commonly used as a model in studies of peatland ecology and peatmoss physiology. Even though it will likely act as a rich source in functional genomics studies in years to come, surprisingly little is known about levels of genetic variability and structuring in this species. Here, we assess for the first time how genetic variation in S. magellanicum is spatially structured across its full distribution range (Northern Hemisphere and South America). The morphologically similar species S. alaskense was included for comparison. In total, 195 plants were genotyped at 15 microsatellite loci. Sequences from two plastid loci (trnG and trnL) were obtained from 30 samples. Our results show that S. alaskense and almost all plants of S. magellanicum in the northern Pacific area are diploids and share the same gene pool. Haploid plants occur in South America, Europe, eastern North America, western North America, and southern Asia, and five genetically differentiated groups with different distribution ranges were found. Our results indicate that S. magellanicum consists of several distinct genetic groups, seemingly with little or no gene flow among them. Noteworthy, the geographical separation of diploids and haploids is strikingly similar to patterns found within other haploid Sphagnum species spanning the Northern Hemisphere. Our results confirm a genetic division between the Beringian and the Atlantic that seems to be a general pattern in Sphagnum taxa. The pattern of strong genetic population structuring throughout the distribution range of morphologically similar plants need to be considered in future functional genomic studies of S. magellanicum.

A list of 401 citations pertaining to the ecology of tropical bryophytes and lichens is presented. The bibliography includes publications addressing the biology, ecology, natural history, and physiology of bryophytes and lichens, but generally eschews taxonomic and floristic papers. All citations have been verified, unless denoted with an asterisk (*). An appendix that groups citations by category is provided.

It is still a fact that most bryologists per area are found in the temperate regions of the northern hemisphere, who have spent up to 200 years (as in Europe) in the exploration of their bryofloras with the result that these countries have not only floras for identification of the comparably low number of species but some countries have already detailed grid maps of the distribution of all species. On the other hand, there are vast regions in the tropics which are very insufficiently explored. So far, the knowledge of bryophytes in these regions was predominantly provided by scientists from North America, Europe or Japan. Still much work is done by scientists and - during the past decades also increasingly - even by advanced amateurs from these countries. Regretably, these activities are often misunderstood by local biologists in the tropics and especially by the authorities of these states as scientific exploitation, and recently collecting of material for genetic studies as plundering of genetic ressources, which is nonsense but makes research difficult or even impossible in such countries. In this regard, the question raises why there are so few bryologists in tropical countries and even no bryologists in many countries? Usually, the lack of ressources such as laboratories, money, libraries, herbaria etc. is presented as arguments, which does not match the point, since many bryologists in industrial countries suffer from similar restrictions and sometimes have worth working consitions than colleagues in tropical countries, but make nevertheless valuable contributions to tropical bryology. Even amateurs have contributed a lot to tropical bryology in the past. The fewest bryologists work in such famous places as Missouri or New York Botanical Garden. Many of them are from eastern, former communistic countries and never gave up to promote tropical bryology under these conditions. In my opinion, the most crucial point is that students in tropical countries get not in contact with bryophytes, and mainly because of the lack of literature. Nobody can expect that students pick up a subject for their thesis if there is no literature available. This manual is therefore devoted to these students. Possibilities to gain a bryological training in industrial countries and paid by these countries were used only by few students, although available. And if these students do not come to us, we have to go to them (which is even cheaper). This is the reason for the increased number of courses on tropical bryology in the past.
