The macroecology of butyrate‐producing bacteria via metagenomic assessment of butyrate production capacity

Ecology and Evolution, Volume 14, Issue 5, May 2024.
Butyrate‐producing bacteria produce the short‐chain fatty acid butyrate and are vital to ecosystem functionality and human health, but the macroecological influences on their biogeographical distribution remain poorly resolved. Here we developed new normalised butyrate production capacity (BPC) indices derived from global metagenomic (n = 13,078) and ...

Nest Biology and Demography of the Fungus-Growing Ant Cyphomyrmex lectus Forel (Myrmicinae; Attini) at a Disturbed Area Located in Rio Claro, SP, Brazil

Sociobiology, 2015
Cyphomyrmex ants are a basal group of small fungus-growers (Myrmicinae:Attini), which differ profoundly from their most studied relatives Atta and Acromyrmex.

Cellulase Production by Trichosporon laibachii

Orbital: The Electronic Journal of Chemistry, 2017
The ability of twenty-three yeast strains isolated from decayed wood and the fungus garden of attine ants to produce hemi- and cellulolytic hydrolases in a chemically defined medium was screened.

Diversity of mycobiota in colonies of different species of leaf-cutting ants and sampling sites across Argentina

Ecología Austral, 2017
Attine ants are a monophyletic group comprising more than 230 species, distributed exclusively in the New World. All higher Attini ants depend on the cultivation of fungus gardens for food, and those gardens are continuously exposed to alien ...

Cooperative Breeding in the Ambrosia Beetle Xyleborus affinis and Management of Its Fungal Symbionts

Frontiers in Ecology and Evolution, 2020
Fungus-farming is known from attine ants, macrotermites, and ambrosia beetles (Scolytinae, Platypodinae). Farming ant and termite societies are superorganismal and grow fungal cultivars in monocultures.

Growth of symbiont fungi of some higher attine ants in mineral medium [PDF]

Ciência Rural, 2004
Bioassays were conducted to verify the possibility of culturing the symbiont fungus of some higher attine in mineral medium and finding out the optimum pH value for their satisfactory mycelial growth. Three organic media and one mineral medium were inoculated with isolates from Atta sexdens piriventris and Acromyrmex heyeri. In mineral medium different

Absence of the Parasite Escovopsis in Fungus Garden Pellets Carried by Gynes of Atta sexdens

Sociobiology, 2015
Before preparing for the mating flight gynes of leaf-cutting ants (Hymenoptera: Formicidae: Attini) harvest and store in an infrabuccal pocket a small fragment of their fungus gardens. This pellet is the start culture of the mutualistic fungus when mated

Towards a molecular understanding of symbiont function: Identification of a fungal gene for the degradation of xylan in the fungus gardens of leaf-cutting ants

BMC Microbiology, 2008
Background Leaf-cutting ants live in symbiosis with a fungus that they rear for food by providing it with live plant material. Until recently the fungus' main inferred function was to make otherwise inaccessible cell wall degradation products available ...

Rediscovery of the enigmatic fungus-farming ant "Mycetosoritis" asper Mayr (Hymenoptera: Formicidae): Implications for taxonomy, phylogeny, and the evolution of agriculture in ants.

PLoS ONE, 2017
We report the rediscovery of the exceedingly rarely collected and enigmatic fungus-farming ant species Mycetosoritis asper. Since the description of the type specimen in 1887, only four additional specimens are known to have been added to the world's ...

From the Tunnels into the Treetops: New Lineages of Black Yeasts from Biofilm in the Stockholm Metro System and Their Relatives among Ant-Associated Fungi in the Chaetothyriales.

PLoS ONE, 2016
Rock-inhabiting fungi harbour species-rich, poorly differentiated, extremophilic taxa of polyphyletic origin. Their closest relatives are often well-known species from various biotopes with significant pathogenic potential. Speleothems represent a unique
