Temperature and host preferences drive the diversification of Saccharomyces and other yeasts: a survey and the discovery of eight new yeast species

Compared to its status as an experimental model system and importance to industry, the ecology and genetic diversity of the genus Saccharomyces has received less attention. To investigate systematically the biogeography, community members and habitat of these important yeasts, we isolated and identified nearly 600 yeast strains using sugar-rich enrichment protocols. Isolates were highly diverse and contained representatives of more than 80...
