“…Cladodes three months old ranging in size from 25 to 30 cm were used in these experiments. Pure cultures of dominant yeast species were isolated from rotting cladodes in Tunisia and maintained on standard yeast culture medium (Pignal & Lachaise, 1979). Identification methods were those of Van der Walt (1970) and Van der Walt & Yarrow (1984).…”

The cactophilic species, Drosophila buzzatii, normally breeds in decaying pockets of Opuntia cladodes, in which there is a complex interaction with the microbial flora, especially yeast species. Isofemale lines were used to estimate genetic variation among larvae reared on their natural feeding substrate. Four naturally occurring cactophilic yeast species isolated from the same Tunisian oasis as the Drosophila population were used. Two fitness components were studied for each line, viability and developmental time. Genetic variations among D. buzzatii lines were observed for both traits. A significant yeast species × isofemale line interaction for viability was also evidenced, suggesting the occurrence of specialized genotypes for the utilization of breeding substrates. This genetic heterogeneity in the natural population may favor a better adaptation to the patchily distribution of yeasts.

“…One interesting work on yeast ecology associated with flies of the family Drosophilidae was done by Pignal and Lachaise (1979) in the Lamto savannahs (Ivory Coast). These authors isolated yeasts from 154 flies belonging to 22 species, and obtained 150 isolates, with Hanseniaspora spp.…”

Tropical rainforests and related biomes are found in Asia, Australia, Africa, Central and South America, Mexico, and many Pacific Islands. These biomes encompass less than 20% of Earth's terrestrial area, may contain about 50% of the planet's biodiversity, and are endangered regions vulnerable to deforestation. Tropical rainforests have a great diversity of substrates that can be colonized by yeasts. These unicellular fungi contribute to the recycling of organic matter, may serve as a food source for other organisms, or have ecological interactions that benefit or harm plants, animals, and other fungi. In this review, we summarize the most important studies of yeast biodiversity carried out in these biomes, as well as new data, and discuss the ecology of yeast genera frequently isolated from tropical forests and the potential of these microorganisms as a source of bioinnovation. We show that tropical forest biomes represent a tremendous source of new yeast species. Although many studies, most using culture‐dependent methods, have already been carried out in Central America, South America, and Asia, the tropical forest biomes of Africa and Australasia remain an underexplored source of novel yeasts. We hope that this review will encourage new researchers to study yeasts in unexplored tropical forest habitats.
