<p>Polish mycosociological studies contribute remarkably to the European mycocoenology. They are widely cited in recent mycoecological research syntheses aiming at the elucidation of the role of fungi in the structure and functioning of plant communities. Thus, there is an urgent need of reviewing our mycosociological works published since the 50’s of the last century. Professor Andrzej Nespiak, who examined cap fungi in the Białowieża National Park, was the first to carry out mycocoenological research in Poland. His work was the turning point for the development of field mycological studies and inspired subsequent generations of our mycologists.</p><p>Mycosociological studies were also stimulated by numerous, frequently outstanding phytosociological examinations of vast areas of the country, particularly of the protected ones.</p><p>The list of 623 mycosociological publications, spanning over 50 years which coincide with the most extensive development of mycosociological studies in Poland, offers material that reflects current trends, approaches, advantages and limitations in research on the participation of fungi in phytocoenoses as well as on fungi forming their own communities.</p><p>Apart from classical mycosociological studies, focusing mostly on basidiomycetes, a few publications describing mycocoenotic role of microscopic fungi are also compiled, including symbiotic, saprotrophic and parasitizing fungi, aquatic and soil species.</p><p>A survey of mycosociological studies carried out in plant communities follows the MATUSZKIEWICZ’S (2001) system of plant syntaxonomy. It offers information which plant communities were investigated and how thoroughly, and which phytocoenoses were not examined mycologically. The project was undertaken to address interests of mycologists and phytosociologists. It is dedicated to the memory of Professor Andrzej Nespiak, the founder of the Polish school of mycosociology.</p>

Photo Essay

If one travels to Little Bighorn Battlefield National Park in late June, one can witness at least three events that simultaneously take place each year commemorating what has been called “one of the great mythic and mysterious military battles of American history” (Frosch, 2010). The National Park Service rangers give “battle talks” on the hour to visiting tourists. Two miles away, the privately run U.S. Cavalry School also performs a scripted reenactment called “Custer’s Last Ride”—with riders who have been practicing all week to play the role of soldiers from the doomed regiment of Custer’s 7th Cavalry. On this same day, a traveling band of men, women, and youth from the Lakota, Northern Cheyenne, and Arapaho Nations who have journeyed by horseback and convoy from the Dakotas and Wyoming will reach Last Stand Hill to remember this “Victory Day” from 1876—one that historians have called the “last stand of the Indians” during the period of conflict known as the “Great Sioux War.” This photo essay offers an autoethnographic account of what some have dubbed the annual “Victory Ride” to Montana based upon my participation as a non-Native supporter of this Ride in 2017, 2018, and 2019.

The skin microbiota of atopic dermatitis (AD) patients is characterized by increased Staphylococcus aureus colonization, which exacerbates disease symptoms and has been linked to reduced bacterial diversity. Skin bacterial communities in AD patients have mostly been described at family and genus levels, while species-level characterization has been limited. In this study, we investigated the role of the bacteria belonging to the Staphylococcus genus using targeted sequencing of the tuf gene with genus-specific primers. We compared staphylococcal communities on lesional and non-lesional skin of AD patients, as well as AD patients with healthy controls, and determined the absolute abundance of bacteria present at each site. We observed that the staphylococcal community, bacterial alpha diversity, and bacterial densities were similar on lesional and non-lesional skin, whereas AD severity was associated with significant changes in staphylococcal composition. Increased S. aureus, Staphylococcus capitis, and Staphylococcus lugdunensis abundances were correlated with increased severity. Conversely, Staphylococcus hominis abundance was negatively correlated with severity. Furthermore, S. hominis relative abundance was reduced on AD skin compared to healthy skin. In conclusion, various staphylococcal species appear to be important for skin health.

Microstructure of high-temperature (>73 °C) siliceous sinter deposited around hot springs and geysers, Yellowstone National Park: the role of biological and abiological processes in sedimentation

High Temperature Sinter

Slightly alkaline hot springs and geysers in Yellowstone National Park exhibit distinctive assemblages of high-temperature (>73 °C) siliceous sinter reflecting local hydrodynamic conditions. The main depositional zones include subaqueous pool and channel bottoms and intermittently wetted subaerial splash, surge, and overflow areas. Subaqueous deposits include particulate siliceous sediment and dendritic and microbial silica framework. Silica framework forms thin, porous, microbe-rich films coating subaqueous surfaces. Spicules with intervening narrow crevices dominate in splash zones. Surge and overflow deposits include pool and channel rims, columns, and knobs. In thin section, subaerial sinter is composed of (i) dark brown, nearly opaque laminated sinter deposited on surfaces that evaporate to dryness; (ii) clear translucent silica deposited subaqueously through precipitation driven by supersaturation; (iii) heterogeneous silica representing silica-encrusted microbial filaments and detritus; and (iv) sinter debris. Brownish laminations form the framework of most sinter deposited in surge and overflow zones. Pits and cavities are common architectural features of subaerial sinter and show concave-upward pseudo-cross-laminations and micro-unconformities developed through migration. Marked birefringence of silica deposited on surfaces that evaporate to dryness is probably a strain effect. Repeated wetting and evaporation, often to dryness, and capillary effects control the deposition, morphology, and microstructure of most high-temperature sinter outside of the fully subaqueous zone. Microbial filaments are abundant on and within high-temperature sinter but do not provide the main controls on morphology or structuring except in biofilms developed on subaqueous surfaces. Millimetre-scale lamination cyclicity in much high-temperature sinter represents annual layering and regular seasonal fluctuations in silica sedimentation.

The community role is needed in the implementation of mangrove forest tourism management, especially in planning activities. The role of the community is the involvement of community itself in the development activities, both in the planning, implementation, evaluation, and the stages of esnjoying the results of the development itself. The purpose in this descriptive qualitative study was to determine the role of community in managing mangrove forest tourism in the subdistrict of Sukadana of Kayong Utara regency. Data collection techniques consist of observation, interviews, and documentation. While the analysis was carried out with descriptive analysis technique. The results of this study indicate that the role of of the sejahtera village community in managing mangrove forest tourism is limited to the maintenance of natural resources, maintenance of cleanliness and nursery of mangrove forests. Due to mangrove forest management is still fully managed by The Gunung Palung National Park Agency, the role of the community in the management of tourism in mangrove forests is still low. Therefore, the involvement of the surrounding community needs special attention and other related parties in utilizing mangrove forest tourism.Keyword: community role, mangrove forest, themanagement of mangrove tourism
