“…1). Functional traits of these microorganisms have been reviewed by Vanderwolf et al (2013), Tomczyk-Żak and Zielenkiewicz (2016), and Joshi and Chettri (2019. Physiologically-active members of the cave microbiota have been specifically targeted, but this was done in a limited number of studies (e.g.…”

“…Impacts were stronger on the prokaryotic communities rather than on eukaryotic communities, irrespective of cave physicochemical properties (Ikner et al, 2007;Alonso et al, 2019). However, fungal diversity might also be impacted, with higher tourism level correlating with lower fungal species richness (Joshi and Chettri, 2019;Wasti and Seelan, 2019). Tourism impact on microorganisms might be indirect, e.g.…”

“…Although not as thoroughly studied as bacteria, phylogenetically diverse eukaryotic microorganisms (fungi and protists) have been described and isolated from the bat guano [43,46,47]. is fungal biodiversity is due to the very specific and stable microclimate of the caves.…”

Bats are emblematic hosts of caves. These small flying mammals deserve special attention because their presence has a great economic and ecological impact; they introduce organic matter, the guano, in the ecosystem they live in. Indeed, “guano” (a Quechua word meaning “fertilizer”) is the accumulation of their fecal matter (excreta); its deposition can reach several meters. The composition of guano is influenced by the bat’s food. In addition to its role within the caves, the bat guano is exploited for various purposes; it is used as an effective fertilizer for the cultivation of plants because of having exceptionally high content of nitrogen, phosphate, and potassium and also for the improvement of detergents and other products of great value for humans. The bat guano hosts various classes of microorganisms (viruses, bacteria, algae, fungi, and protists), which are adapted to the cave environment. Since guano is highly acidic, these microorganisms can be considered as extremophiles. They produce functional organic compounds in extreme conditions that could be of interest not only in the drug industry but also in different biotechnological areas. Here, we review already available information on the ecological and economic effects of bats and their guano. We report their food preferences, foraging behaviors, and environmental impacts. Information on these aspects may be useful in finding a solution about protection and preservation of bat populations.

“…Hypogean cultural heritage monuments are often exposed to extreme conditions [ 1 , 2 , 3 , 4 ], with the fungal community under these circumstances being strongly shaped by other microbes (e.g., photoautotrophs) and external factors (e.g., animal vectored dispersion, water availability and anthropogenic activities) [ 4 , 5 , 6 ]. When dealing with stone monuments, fungi are known to be one of the most important biodeteriorative microorganisms since they can deeply alter stone integrity, structural and aesthetic characteristics [ 7 , 8 , 9 ].…”

Stone monuments and relics are prone to biodeterioration processes prompted by microbial proliferation and activity. Among the distinct microbes capable of stone colonization, fungi are known to strongly contribute to stone biodeterioration. During the ongoing efforts aiming to study fungi thriving in dolomitic limestone walls of the Coimbra’s hypogean Roman cryptoporticus (Portugal), two unknown Bionectriaceae isolates were retrieved. The aim of this work was to depict the molecular and phenotypic characteristics of these microorganisms. The phylogenetic analyses revealed that the studied strains could not be assigned to any of the currently known Bionectriaceae genera. Moreover, the isolates exhibited distinctive and peculiar characteristics, such as the packing of conidia by surrounding hyphal segments and the formation of rope-like microsclerotia with a textura globose. Taking into account all the data obtained, a novel genus and species, Circumfusicillium cavernae gen. et sp. nov. in Bionectriaceae (Hypocreales), is proposed here.
