Abstract
Temporal variation in community composition is central to our understanding of the assembly and functioning of microbial communities, yet the controls over temporal dynamics for microbiomes of long-lived plants, such as trees, remain unclear. Temporal variation in tree microbiomes could arise primarily from seasonal (i.e., intra-annual) fluctuations in community composition or from longer-term changes across years as host plants age. To test these alternatives, we experimentally isolated temporal variation in plant microbiome composition using a common garden and clonally propagated plants, and we used amplicon sequencing to characterize bacterial/archaeal and fungal communities in the leaf endosphere, root endosphere, and rhizosphere of two Populus spp. over four seasons across two consecutive years. Microbial community composition differed among seasons and years (which accounted for up to 21% of the variation in microbial community composition) and was correlated with seasonal dissimilarity in climatic conditions. However, microbial community dissimilarity was also positively correlated with time, reflecting longer-term compositional shifts as host trees aged. Together, our findings demonstrate that temporal patterns in tree microbiomes arise from both seasonal fluctuations and longer-term changes, which interact to generate unique seasonal patterns each year. In addition to shedding light on two important controls over the assembly of plant microbiomes, our results also suggest future studies of tree microbiomes should account for background temporal dynamics when testing the drivers of spatial patterns in microbial community composition and temporal responses of plant microbiomes to environmental change.IMPORTANCEMicrobiomes are integral to the health of host plants, but we have a limited understanding of the factors that control how the composition of plant microbiomes changes over time. Especially little is known about the microbiome of long-lived trees, relative to annual and non-woody plants. We tested how tree microbiomes changed between seasons and years in poplar (genus Populus), which are widespread and ecologically important tree species that also serve as important biofuel feedstocks. We found the composition of bacterial, archaeal, and fungal communities differed among seasons, but these seasonal differences depended on year. This dependence was driven by longer-term changes in microbial composition as host trees developed across consecutive years. Our findings suggest that temporal variation in tree microbiomes is driven by both seasonal fluctuations and longer-term (i.e., multiyear) development.

Abstract
The purpose of the study was to evaluate an Ontario Ministry of Health (MOH) cold/flu self-care public education campaign to reduce unnecessary patient visits to doctors. The MOH campaign consisted of an information booklet delivered to every household in an Ontario city, newspaper ads and radio spots. The program ran during January-March 1994. The evaluation consisted of: (1) 2x2 telephone survey in London (experimental area) and Windsor (comparison area), before and during the campaign; and (2) a telephone survey of London family practitioners during the campaign. In addition, data on the incidence of cold/flu visits to three hospital emergency departments and a sample of family physicians' offices were gathered. The data suggest that program rationale may have been questionable because the majority of the surveyed public were knowledgeable and self-reported appropriate doctor visits for cold/flu. Campaign evaluation showed limited impact. Message penetration was low; only one-third of London residents knew of the campaign or read the booklet. Only two of 10 questions showed increases in knowledge in London and no changes were found for beliefs, attitudes, acquisition of new health practices or self-reported visits to the doctor. The physician survey, emergency room and family physician office visit data were consistent with the public survey findings.
