Nectar yeasts warm the flowers of a winter-blooming plant.
Yeasts are ubiquitous in terrestrial and aquatic microbiota, yet their ecological functionality remains relatively unexplored in comparison with other micro-organisms. This paper formulates and tests the novel hypothesis that heat produced by the sugar catabolism of yeast populations inhabiting floral nectar can increase the temperature of floral nectar and, more generally, modify the within-fl...
متن کاملThe impact of nectar chemical features on phenotypic variation in two related nectar yeasts.
Floral nectars become easily colonized by microbes, most often species of the ascomycetous yeast genus Metschnikowia. Although it is known that nectar composition can vary tremendously among plant species, most probably corresponding to the nutritional requirements of their main pollinators, far less is known about how variation in nectar chemistry affects intraspecific variation in nectarivoro...
متن کاملSpecialist nectar-yeasts decline with urbanization in Berlin
Nectar yeasts are common inhabitants of insect-pollinated flowers but factors determining their distribution are not well understood. We studied the influence of host identity, environmental factors related to pollution/urbanization, and the distance to a target beehive on local distribution of nectar yeasts within Robinia pseudoacacia L. and Tilia tomentosa Moench in Berlin, Germany. Nectar sa...
متن کاملNectar-living yeasts of a tropical host plant community: diversity and effects on community-wide floral nectar traits
We characterize the diversity of nectar-living yeasts of a tropical host plant community at different hierarchical sampling levels, measure the associations between yeasts and nectariferous plants, and measure the effect of yeasts on nectar traits. Using a series of hierarchically nested sampling units, we extracted nectar from an assemblage of host plants that were representative of the divers...
متن کاملNectar-living yeasts of a tropical host plant community: Diversity and effects
4 We characterize the diversity of nectar-living yeasts of a tropical host plant community at 5 different hierarchical sampling levels, measure the associations between yeasts and 6 nectariferous plants, and measure the effect of yeasts on nectar traits. Using a series of 7 hierarchically nested sampling units, we extracted nectar from an assemblage of host plants 8 that were representative of ...
