“…Due to their significant metabolic flexibility, Ascomycota members are widely used in various biotechnological applications, such as the production of fatty alcohols, fatty acids, and biofuels and the reduction and degradation of chemicals and solvents [15,16]. Basidiomycota is also a major phylum in the kingdom of fungi, with more than 31,000 known species, which is second only to Ascomycota in species numbers [17]. Furthermore, these fungi in coffee samples were confirmed to belong to 10 genera, as shown in Figure 2D.…”

Coffee fermentation is crucial for flavor and aroma, as microorganisms degrade mucilage and produce metabolites. This study aimed to provide a basis for understanding the impact of microorganisms on Coffea arabica from Yunnan, China, during washed processing. The microbial community structure and differentially changed metabolites (DCMs) of C. arabica beans during washed processing were analyzed. The results indicated that the top five predominant microorganisms at the genera level were Achromobacter, Tatumella, Weissella, Streptococcus, and Trichocoleus for bacteria and Cystofilobasidium, Hanseniaspora, Lachancea, Wickerhamomyces, and Aspergillus for fungi. Meanwhile, the relative content of 115 DCMs in 36 h samples decreased significantly, compared to non-fermentation coffee samples (VIP > 1, p < 0.05, FC < 0.65), and the relative content of 28 DCMs increased significantly (VIP > 1, p < 0.05, FC > 1.5). Furthermore, 17 DCMs showed a strong positive correlation with microorganisms, and 5 DCMs had a strong negative correlation (p < 0.05, |r| > 0.6). Therefore, the interaction and metabolic function of microbiota play a key role in the formation of coffee flavor, and these results help in clarifying the fermentation mechanisms of C. arabica and in controlling and improving the quality of coffee flavor.

“…Fossil fungi have been documented throughout the Phanerozoic (Taylor et al ., 2015a), but fungal relationships with land plants and other fungi from the Lower Devonian, Carboniferous, Triassic, Cretaceous, and Cenozoic have attracted increased attention. The simple reason for this is the existence of exceptional rock or amber deposits from these periods of time that faithfully preserve numerous fungi together with their hosts, and thus provide direct insights into different levels of fungal interaction with other organisms in ancient ecosystems (Taylor and Krings, 2010;Taylor et al ., 2015aTaylor et al ., , 2015bKrings et al ., 2017bHalbwachs et al ., 2021). Documented fossil evidence of parasitic fungi in general is relatively rare, due primarily to the fact that, of all the potential levels of fungal interaction, parasitism is probably the most difficult to demonstrate based on fossils (Harper and Krings, 2021).…”

Parasitic fungi occur in virtually every ecosystem, where they can significantly affect the functions of other organisms. Fungal parasites were probably also widespread in the geologic past. However, evidence of fossil fungi and their ecological roles is relatively rare. Here we demonstrate a spectrum of (putative) parasitic relationships in ancient continental ecosystems, using fossil examples of Chytridiomycota, zygomycetous fungi, Basidiomycota, and Ascomycota, along with several fungal fossils whose affinities remain unknown, from different periods of the Phanerozoic. Although many of the hosts no longer exist, the fungi involved mostly appear morphologically very similar to extant forms.

Where the Immatures of Triassic Diptera Developed

Immature Diptera are more diverse and abundant in fresh water than any other insect order. The question arises whether the earliest dipterans, known from the Upper Buntsandstein of Europe (early Anisian, Middle Triassic), already developed in water and whether such mode of life was inherited from the ancestor of the order or if, alternatively, the dipteran larvae were ancestrally terrestrial. Nematoceran immatures have become common and diverse in the Mesozoic fossil record since the Middle Jurassic, but the vast majority of them represent only two culicomorphan families, Chaoboridae and Chironomidae. Earlier records and records of immatures of other families from the Mesozoic are extremely rare. A total of four larvae and about 30 pupae have been described from Anisian assemblages of France and Spain. Among these, one larva clearly belongs to Culicomorpha, the infraorder most closely associated with fresh waters, and one larva to Bibionomorpha, the infraorder most closely associated with terrestrial habitats, while the rest are hard to classify. Nevertheless, most of the pupae are morphologically similar to the semi-aquatic pupae of extant Limoniidae and Ptychopteridae from wet habitats. The oligopneustic respiratory systems of the Anisian larvae and their apparently allochthonous burial also suggest their semi-aquatic development, which appears to have been the ancestral mode of life of Diptera. The absence of dipteran immatures in lacustrine Konservat-Lagerstätten of the Madygen and the Cow Branch Formations (Ladinian–Carnian and Norian, respectively) is explained by the aquatic conditions being unfavorable for insect immatures and invertebrates in general.
