A literature-based checklist of species of Aspergillus, Penicillium, and Talaromyces recorded in the Brazilian tropical dry forest (Caatinga), the largest tropical dry forest region in South America, is provided. A total of 130 species (60 Aspergillus, 57 Penicillium, and 13 Talaromyces) are reported. Soil was the most common substrate, with 122 species records. Various reported species are well known in biotechnological processes. This checklist reflects the limited knowledge of fungal species in tropical dry environments. These data provide a good starting point for biogeographical studies on species of Aspergillus, Penicillium, and Talaromyces in dry environments worldwide. In addition, the new species Penicillium vascosobrinhous is introduced, an endophytic fungus isolated from cactus of the Caatinga forest in Brazil.

“…This dissimilarity may be associated with the ecological properties of the fungi as well as their ability to survive and reproduce in the termitosphere. Therefore, the availability of organic matter from the feces and the partially controlled microclimate within the termite nests favor the establishment and the proliferation of specific fungal species [3]. Interestingly, the fungi associated with the gut and nest walls of the sympatric grass/litter feeder C. cumulans was composed only by representatives of Dothideomycetes, suggesting some degree of host-specificity by fungi.…”

Microbial Communities of the Gut and Nest of the Humus- and Litter-Feeding Termite Procornitermes araujoi (Syntermitinae)

The evolution of the symbiotic association with microbes allowed termites to decompose ingested lignocellulose from plant-derived substrates, including herbivore dung and soil humus. Representatives of the Syntermitinae (Termitidae) range in their feeding habits from wood and litter-feeding to humus-feeding species. However, only limited information is available about their feeding ecology and associated microbial communities. Here we conducted a study of the microbial communities associated to the termite Procornitermes araujoi using Illumina sequencing of the 16S and ITS rRNA genes. This species has been previously included in different feeding guilds. However, most aspects of its feeding ecology are unknown, especially those associated to its symbiotic microbiota. Our results showed that the microbial communities of termite guts and nest substrates of P. araujoi differed significantly for bacteria and fungi. Firmicutes dominated the bacterial gut community of both workers and soldiers, whereas Actinobacteria was found in higher prevalence in the nest walls. Sordariomycetes was the most abundant fungal class in both gut and nest samples and distinguish P. araujoi from the grass/litter feeding Cornitermes cumulans. Our results also showed that diversity of gut bacteria were higher in P. araujoi and Silvestritermes euamignathus than in the grass/litter feeders (C. cumulans and Syntermes dirus), that could indicate an adaptation of the microbial community of polyphagous termites to the higher complexity of their diets.

“…are small in size relative to their host and they are usually found in the central parts of the host nest where individuals of host colony are rarely observed (Cunha et al, 2003). The aggregation of the inquilines in the central part of host nest may be related to the fact that they use this structure as a food resource (Mathews, 1977;Bourguignon et al, 2011;Cristaldo et al, 2012;Florencio et al, 2013;Barbosa-Silva et al, 2016). In addition, recent studies have shown evidence that individuals of I. microcerus can use chemical cues as a strategy to avoid conflicts, since they avoid chemical cues of the whole body, as well as the trail and alarm signals emitted by its host, C. cyphergaster (Cristaldo et al, 2014;.…”

Constrictotermes sp. nests are frequently inhabited by colonies of Inquilinitermes microcerus. In this association, I. microcerus colonies usually establish their colonies spatially isolated from Constrictotermes colonies. Here, we investigated whether the apparent spatial isolation of I. microcerus colonies in Constrictotermes nests should be related to their needs (e.g. feeding) in relation to the central part of the nest or to a possible stress provoked by the presence of the host. For this, survival and walking behavior bioassays were performed to test the hypothesis that the survivorship of inquilines is: (i) reduced in the presence of host, mainly of those from different nests, (ii) increased in contact with inner walls compared with external walls; and that the distance walked and walking velocity of inquiline is: (iii) increased in the presence of the host and (iv) reduced in contact with the internal walls compared with external walls of host nest. The mean time to death of inquiline workers is lower in contact with host (independently from the same or different nest) compared with control and the mean time to death of inquiline workers is lower in contact with external walls of host nest compared with control group and the inner walls. The distance walked and walking velocity of inquiline workers in contact with their hosts (from the same or different nest) did not differ from control, however, these parameters were reduced when workers were in contact with inner and external walls compared with control. In general, our results showed that I. microcerus adopt behavioral strategies to avoid perception by its host.
