“…Cladonia vulcani is described as a volcano lichen for its occurrence in volcanic areas especially near solfataras actively emitting toxic sulfurous gases such as sulfur dioxide and hydrogen sulfide (19,42,43). Although correlation between sulfurous gases and C. vulcani has been indicated (19) the type of gas that affects C. vulcani habitation has remained inconclusive. In our study, we detected hydrogen sulfide gas in all sampling locations, whereas sulfur dioxide gas was hardly detected in Kusatsu according to previous reports (44,45).…”

Chemosynthetic symbioses between sulfur-oxidizing bacteria and aquatic eukaryotes have been discovered globally in sulfide-rich environments, notably deep-sea hydrothermal vents, cold seeps, and sulfidic cave systems. However, to the best of our knowledge, such chemosymbiotic lifestyles have not been reported from terrestrial eukaryotes. Here we report that the volcano lichen Cladonia vulcani Savicz ubiquitously associates with a single bacterial species that could potentially use hydrogen sulfide as a source of energy. We identified sequences of the bacterium in all 27 samples collected from five geothermal areas across Japan with cellular abundance comparable to the fungal partner. The assembled bacterial genome contained genes involved in sulfur oxidation. The stable association with a potential sulfur-oxidizer is likely to represent an obligate tripartite symbiotic system consisting of fungal, algal, and bacterial partners that has enabled adaptation to the extreme environment.

“…Geothermal areas with volcanic steam vents that constantly emit significant hydrogen sulfide gas typically present desolated open fields with very limited vegetation. The volcano lichen Cladonia vulcani Savicz is one of the few organisms that can thrive in such areas commonly forms extensive covers on ground beside active vents (19).…”

“…We utilized three bioclimatic zones spanning the latitudinal gradient of Finland (south, mid, and north boreal) to represent regional climatic conditions (Table S.1, Fig. S.1; Ahti et al, 1968). This resulted in eight data partitions (the highest BA range was dropped for the north boreal zone given lack of sufficient out-of-sample data) with a minimum of 54 communities (mid-boreal, high basal area) and a maximum of 565 communities (south-bo-real, mid basal area; Table S.2).…”

Identifying the ecological processes underlying community assembly remains an elusive goal in community ecology. We formalize assembly hypotheses as alternative models and apply each to predict 1,918 out-of-sample boreal forest understory communities to identify and separate the processes driving community assembly. Models are specified within a Bayesian joint species distribution framework that allows for the inclusion and separation of stochastic processes, environmental filtering, and two different species dependence structures. We found clear evidence that study communities are structured by both environmental filtering and compositional dependence highlighting the importance of selection in community assembly. The relative importance of environmental filtering was greater than compositional dependence in predicting both understory communities and the abundance of constituent species across broad suc-cessional and bioclimatic gradients. Contrary to ecological expectations, the inclusion of a flexible residual species dependence structure (accounting for more than compositional dependence) did not improve model predictions after accounting for the strong role of environmental filtering. Our results provide novel inference on the processes underlying community assembly facilitated by applying empirical approximations of alternative assembly processes to predict communities across a range of environmental conditions.

Abstract:The lichen biota of the Zeysky Nature Reserve (southern Russian Far East) was studied in the course of geobotanical expedition. In total 36 species of lichens and one lichenicolous fungus are reported for the first time for the reserve. Among them 19 are new to the Amur Region. Parmelia asiatica is reported for the first time for the southern Russian Far East, Cladonia norvegica -for the Asian part of Russia, Tuckermannopsis gilva -for Russia, Melanohalea laciniatula -for Asia. Four species are included in the Red Data Book of Russian Federation.
