Fungus‐farming termites cultivate a Termitomyces fungus monoculture in enclosed gardens (combs) free of other fungi, except during colony declines, where Pseudoxylaria spp. stowaway fungi appear and take over combs. Here, we determined Volatile Organic Compounds (VOCs) of healthy Macrotermes bellicosus nests in nature and VOC changes associated wit...

In recent decades, African vulture populations have experienced a distressing decline, with certain species plummeting by over 90%. This decline can largely be attributed to various human‐induced pressures. In West Africa, the trade of vultures for magico‐traditional medicine stands out as a significant threat. However, there remains a dearth of kn...

Full-text available
Fungus-farming termites (Macrotermitinae) engage in an obligate mutualism with members of the fungal genus Termitomyces, which they maintain as a monoculture on specialized comb structures. Both these comb structures and the guts of the termites host diverse bacterial communities that are believed to assist in sustaining monoculture farming through...

Termitomyces is a genus of basidiomycete fungi cultivated by termites of the subfamily Macrotermitinae. This symbiosis originated in central Africa, and subsequently, the fungus-growing termites have colonized almost the entire African continent including Madagascar as well as significant parts of Asia. Around 40 species of Termitomyces have been d...

Bees are vital to both ecosystems and humans worldwide; supplying a range of key support facilities for the successful breeding of the majority of flowering plants. The aim of this study was to assess the bee species composition in a Sudano‐Guinean savanna zone and determining the impact of a set of environmental parameters influencing this species...
Article
Full-text available
Fungus-farming termite colonies maintain monoculture fungus combs in underground chambers without apparent problems with diseases. Multiple lines of defense contribute to the suppression or removal of antagonists of the symbiosis, but the role of the termite-manipulated environment within mounds has yet to be tested. Specifically, termite mounds ha...

Fungus‐farming termites are dominant decomposers and important ecosystem engineers in their natural sub‐Sahara African and Southeast Asian ecosystems. This is accomplished through integrated behavioral management of complex communities of fungal and bacterial symbionts by the termite host that facilitate plant biomass decomposition and production o...
Article
Termites are essential components of tropical ecosystems, in which they provide fundamental ecosystem services, such as decomposition of dead plant material, fostering of soil mineralization and provisioning of new microhabitats. We investigated the termite communities of four habitats in two protected areas in West Africa, which differ in manageme...

Fungus-growing termites (Isoptera: Macrotermitinae) dominate African savannah ecosystems where they play important roles in ecosystem functioning. Their ecological dominance in these ecosystems has been attributed to living in an ectosymbiosis with fungi of the genus Termitomyces (Lyophyllaceae). Evolutionary theory predicts that the transmission m...
Article
Full-text available
Background Monoculture farming poses significant disease challenges, but fungus-farming termites are able to successfully keep their monoculture crop free from contamination by other fungi. It has been hypothesised that obligate gut passage of all plant substrate used to manure the fungal symbiont is key to accomplish this. Here we refute this hypo...

Full-text available
Termites are important ecosystem engineers. Yet they are often difficult to identify due to the lack of reliable species-specific morphological traits for many species, which hampers ecological research. Recently, termitologists working with West African termites (West African Termite Taxonomy Initiative) convened for a workshop with the aim of beg...
Article
Full-text available
Termites are one of the major components of tropical ecosystems. However, the ecological and biological variables determining the structure of their communities within natural habitats are less documented in general and especially in the Comoe National Park, a Sudano-Guinean savanna zone located in the north-eastern part of Côte d’Ivoire (West Afri...

To maintain savanna vegetation, mid-seasonal fire has been applied since 1961 in the Lamto Savanna (Côte d'Ivoire). However, this prescribed fire has not impeded tree encroachment during recent years, nor have its effects on insect assemblages been documented. Also the impact of tree intrusion on insect assemblages is poorly studied in savanna. To...

Background: Molecular methods have revolutionized studies in fungal taxonomy, ecology, and evolution. In addition, nucleotide-based systematic and phylogenies are also the major source for inference of macro-evolutionary processes in fungi since fossils are rare and unevenly distributed between taxa. Despite the mega-diversity of tropical African f...

The Macrotermitinae subfamily is characterized by its symbiosis with fungi of the genus Termitomyces. The most common and presumably primitive mode of reproduction for these fungi is to produce basidiocarps on the mounds of the host termite colony. The seasonal fructification pattern of the fungi seems to depend on the habitat type and termite ecol...
Article
The mutualistic symbiosis between fungus-growing termites and Termitomyces fungi originated in Africa and shows a moderate degree of interaction specificity. Here we estimate the age of the mutualism and test the hypothesis that the major splits have occurred simultaneously in the host and in the symbiont. We present a scenario where fungus-growing...
