“…In terms of biogeography, most studies have been carried out in temperate regions of the Northern Hemisphere, including alpine and subalpine mountains (Ronikier & Ronikier, ; Novozhilov et al ., ), tundra (Novozhilov et al ., ; Stephenson et al ., ), winter‐cold deserts (Schnittler & Novozhilov, ; Schnittler, ; Novozhilov & Schnittler, ) and temperate grasslands (Rollins & Stephenson, ). Only recently have other parts of the world, such as tropical zones, warm deserts or the Patagonian steppe been studied systematically (Estrada‐Torres et al ., ; Wrigley de Basanta et al ., ; Lado et al ., , , ). At the level of morphologically recognizable taxa, many myxomycete species display cross‐continental distribution patterns (Stephenson et al ., ).…”

Aim Lowland/highland and Neotropical/Asian Palaeotropical assemblages of myxomycetes were compared to test the null hypothesis that neither species diversity nor species composition differs between the two ecoregions. This can be expected if myxomycetes behave as ubiquists and are capable of unlimited long distance dispersal. Location Four pairs (lowland/highland) of comprehensive regional surveys encompassing c. 7500 specimens were compared; these represented Neotropical (Yasuni/Maquipucuna in Ecuador; Guanacaste/Monteverde in Costa Rica) and Asian Palaeotropical forests (Cat Tien/Bi Dup Nui Ba in Vietnam; Chiang Mai in Thailand/South Luzon in the Philippines). Methods Each survey was carried out in an area characterized by relatively homogenous vegetation consisting of natural or near‐natural forests, and incorporated both field collecting and the use of moist chamber cultures, and all observed fructifications were recorded. Analyses of diversity (i.e. richness) and community composition were carried out with EstimateS and R. Results Between 400 and 2500 records per survey were obtained. Species accumulation curves indicated moderate to nearly exhaustive completeness (70–94% of expected species richness recorded). Multivariate analyses suggest that geographical separation (Neotropic versus Palaeotropic) explained the observed differences in composition of myxomycete assemblages better than habitat differences (lowland versus highland forests). Main Conclusion Both geographically restricted morphospecies and differences in myxomycete assemblages provide evidence that myxomycetes are not ubiquists but tend to follow the moderate endemicity hypothesis of protist biogeography.

“…Two larger biomes are especially well studied: the hot deserts characterized by a rich flora of succulent plants in the southern United States (Blackwell and Gilbertson 1980, 1984, Evenson 1961), Mexico (Estrada-Torres et al 2009) and South America (Lado et al 2007(Lado et al , 2012, and the winter-cold steppes and shrub deserts of Middle and Central Asia. For the latter task, this paper presents the most easternmost survey within Central Asian deserts.…”

“…Thought to be most diverse in moist forests, numerous studies in arid ecosystems, employing extensively the moist chamber culture method, have shown that arid regions have at least a comparable diversity (e.g., Colorado: Novozhilov et al 2003;arid zones of Mexico: Estrada-Torres et al 2009; dry innerAndean basins: Lado et al 2012). Within a series of surveys throughout Middle and Central Asia, reaching from the Caspian Lowlands (Novozhilov et al 2006) and western Kazakhstan (Schnittler and Novozhilov 2000) over innermountain basins of the Russian Altay (Novozhilov et al 2009) to Mongolia we explored the diversity of myxomycetes in the winter-cold steppes and deserts of Central Asia.…”

Myxomycete diversity in the Tarim basin and eastern Tian-Shan, Xinjiang Prov., China

We report the results of a survey for myxomycetes in the Chinese province of Xinjiang, covering the northern part of the Tarim basin and the eastern Tian-Shan mountains. Sampling in the hyperarid Tarim basin focused on monospecific Tugai forests; these are park-like stands of the phreatophyte Populus euphratica. In a transect from the Tarim basin to the mountains, trees vanish outside the basin, but reoccur at ca. 1,400 m elevation as monospecific forests of Picea schrenkiana; the second focal area of the study. From a total of 362 substrate samples (245 from the Tarim basin, 177 from the mountains) we obtained 477 determinable records of myxomycetes, plus a total of 206 field collections, the latter almost exclusively from the spruce forests in the mountains. From the 80 taxa recorded 53 are represented by field collections, and 32 were found in moist chamber cultures; with a very low overlap in species assemblages found in the field and in cultures. Although receiving less than 50 mm annual precipitation, corticolous myxomycetes were common in the Tugai forests, with Physarum pseudonotabile ad. int., Didymium anellus, Echinostelium colliculosum and Protophysarum phloiogenum as the most common species. Compared to the Tarim basin (21 taxa) the mountains were much richer in myxomycetes (75 taxa), although the diversity recovered from cultures was comparable (21 vs. 28 taxa). Most species from the mountains fruited on decaying spruce, often collected under or even inside the logs due to the extremely dry air. Our results suggest first that there is no lower limit of annual precipitation for myxomycetes, as long as at least some days with nightly dew fall allow these organisms to complete their life cycle. Second, the two examples of surprisingly diverse myxomycete assemblages from monospecific forests demonstrate, that species richness of this group is not necessarily connected with plant diversity of the habitat. This survey is the most eastern of a large-scale study of myxomycete diversity throughout Middle and Central Asia.

“…Didymium dubium has been reported from all of the continents except Africa. In the Neotropical region it has been cited in Argentina, Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador, Guatemala, Mexico and Venezuela (LADO; WRIGLEY DE BASANTA, 2008;BEZERRA et al, 2008;LADO et al, 2013). This species is known as a nivicolous species, and is usually found between 2,000 and 4,000 m above sea level (FARR, 1976;LADO, 2004;LADO et al, 2005) Park, Sergipe state (adjacent to Alagoas).…”

Myxomycetes do estado de Alagoas (Brasil) e notas sobre sua distribuição. O estado de Alagoas, localizado na Região Nordeste do Brasil, abrange uma área de 27.767 km 2 onde diferentes ecossistemas, incluindo manguezal e Floresta Atlântica na costa e caatinga no interior, são encontrados. A literatura relata a ocorrência de 4 esp cies de Myxomycetes no estado, as uais foram registradas em ambientes orestais midos ou em baga o de cana de a car armazenado em ind stria. Este estudo o primeiro a registrar esp cies de Didymiaceae e os gêneros Badhamia, Comatricha, Perichaena, Reticularia e Stemonaria para Alagoas. É apresentada uma chave para espécies. Licea succulenticola, Reticularia jurana e Stemonaria longa são novas referências para o bioma Caatinga. Licea succulenticola é registrada pela primeira vez no Brasil.
