“…Phylogenetic analyses show our new species clusters with M. pisiformis with high statistical support (99% in ML, and 1 in PP) (Supplementary Figure 3). Morphological comparisons show that M. pisiformis has 25.5–33 μm globose sporangia with 7.5–10 × 12.5–15 μm ellipsoid, pea-shaped, sporangiospores [ 59 ], while our new species has 20–50 × 20–50 µm globose to subglobose sporangia with 2–12 × 2.5–12 µm globose to subglobose sporangiospores. Based on a blast search of NCBIs GenBank nucleotide database, the closest hits received using the ITS sequence of our new species are Mortierella sp.…”

“…This holds particularly true in China, a country thought to contain one of the world’s largest cave-containing limestone karsts systems [ 58 ]. This point is further emphasized by the work of Deharveng et al [ 59 ], who reported that 90% of species collected during a caving expedition in Mulun, a National Nature Reserve in Guangxi Province, China, were new to science.…”

Virulent infectious fungal diseases, in natural and managed landscapes, are increasing. Fungal diseases in humans, animals and plants have caused die-off and extinction events and have become a threat to food security. A caving expedition in Yunnan Province, China, revealed two bat carcasses covered in fungal mycelia. Eleven fungal isolates were obtained from these bat carcasses, and morphological observations and multigene phylogenetic analyses revealed they were Fusarium incarnatum, Mucor hiemalis and Trichoderma harzianum and four new species, Mortierella rhinolophicola, M. multispora, M. yunnanensis and Neocosmospora pallidimors. One of the more alarming findings is that a number of infections related to Neocosmospora, previously associated with human and animal mycotoxicoses, are reported to be increasing, and here we present a new species from this genus, isolated from dead bats. Due to the ecosystem services provided by bats, and the close relationship between bats and humans, future research should focus on the impacts and significance of N. pallidimors to human and animal health, examining its pathogenicity and secondary metabolites. Taxonomic descriptions, color images of the habitat, in situ samples, microstructures and cultures are presented. SEM photographs of microstructures and phylogenetic trees showing the placement of new and known species are also provided.

“…Troglomorphic features in Collembola are large body size, elongated appendages (antennae, and to a lesser degree legs and furca), multiplication of antennal chaetae, elongated and slender claw complex, pointed tenent hair, blindness and depigmentation (Christiansen 2012, Deharveng and Bedos 2018, Lukić et al 2018). Troglomorphic Collembola are increasingly reported from the tropics, but the degree of troglomorphy in the species described so far is less strong than in temperate regions.…”

The most highly troglomorphic Collembola of Southeast Asia, Coecobryasirindhornaesp. n., is described from a cave in Satun province, Thai Peninsula. It is characterised by its large size, extremely elongated antennae, relatively long legs and furca, reduced macrochaetotaxy, very long and slender claw, pointed tenent hair, four sublobal hairs on outer maxillary lobe, and the absence of eyes and pigmentation. A checklist of Thai Coecobrya species and a key to the troglomorphic species of Thailand are provided. Troglomorphy and conservation of cave habitats in the area are discussed.

“…Additional questions focused on the most common evolutionary processes (Q19), and the influence of biotic and abiotic factors (Q16) that lead to different patterns of diversification across subterranean lineages (Q12). Important subterranean radiations are known in all major taxonomic groups (Deharveng & Bedos, 2019), but only a few of them have been well documented. These include Amphipoda (Zakšek et al ., 2019), Collembola (Lukić et al ., 2019), and Coleoptera (Leys et al ., 2003; Faille et al ., 2010; Njunjić et al ., 2018).…”

Fundamental research questions in subterranean biology

Five decades ago, a landmark paper in Science titled The Cave Environment heralded caves as ideal natural experimental laboratories in which to develop and address general questions in geology, ecology, biogeography, and evolutionary biology. Although the ‘caves as laboratory’ paradigm has since been advocated by subterranean biologists, there are few examples of studies that successfully translated their results into general principles. The contemporary era of big data, modelling tools, and revolutionary advances in genetics and (meta)genomics provides an opportunity to revisit unresolved questions and challenges, as well as examine promising new avenues of research in subterranean biology. Accordingly, we have developed a roadmap to guide future research endeavours in subterranean biology by adapting a well‐established methodology of ‘horizon scanning’ to identify the highest priority research questions across six subject areas. Based on the expert opinion of 30 scientists from around the globe with complementary expertise and of different academic ages, we assembled an initial list of 258 fundamental questions concentrating on macroecology and microbial ecology, adaptation, evolution, and conservation. Subsequently, through online surveys, 130 subterranean biologists with various backgrounds assisted us in reducing our list to 50 top‐priority questions. These research questions are broad in scope and ready to be addressed in the next decade. We believe this exercise will stimulate research towards a deeper understanding of subterranean biology and foster hypothesis‐driven studies likely to resonate broadly from the traditional boundaries of this field.
