Consequences of a nectar yeast for pollinator preference and performance
TL;DR: It is suggested that nectar yeasts can enhance floral signaling as well as alter pollinator foraging behavior at individual flowers, though they may not directly affect pollinator performance.

Yeasts in nectar enhance male fitness in a montane perennial herb
TL;DR: Results provide evidence of effects of nectar-inhabiting yeasts on male plant fitness and highlight the importance of microorganisms in mediating plant-pollinator interactions and subsequent plant fitness.

Generalising indirect defence and resistance of plants

TL;DR: It is argued that the range of plant traits that mediate indirect defence is much greater than previously thought, and major concepts surrounding their ecological functioning are further organised.

Microbial metabolites elicit distinct olfactory and gustatory preferences in bumblebees
Robert N. Schaeffer,Robert N. Schaeffer,Caitlin C. Rering,Isabelle Maalouf,John J. Beck,Rachel L. Vannette +5 more
TL;DR: The hypothesis that species of nectar-inhabiting microbes differentially influence pollinator attraction and feeding via microbial metabolites produced in nectar is tested and suggests that microbial metabolites have significant potential to shape interspecific, plant–pollinator signalling, with consequences for forager learning, economics and floral host reproduction.

Joint species distribution modelling for spatio‐temporal occurrence and ordinal abundance data
Erin M. Schliep,Nina K. Lany,Phoebe L. Zarnetske,Robert N. Schaeffer,Colin M. Orians,David A. Orwig,Evan L. Preisser +6 more
TL;DR: The robust modelling approach could provide similar insights for other community modules of co-occurring species and the autoregressive component revealed weak evidence for commensalism, in which adelgid may have predisposed hemlock stands for subsequent infestation by scale.
