Figure 3. Microhabitat parameters identified as most important vary for likelihood of recruitment (a), relative recruit counts (b), 1-year seedling survival (c), and 2-year seedling survival (d). Percentages calculated from the total times a parameter was used in model selection for all species, with pink indicating a negative effect and green indicating a positive effect. Legend in all panels is as in (b). Note that each panel corresponds to a different number of models (see Tables 1, S3). Summer temperature and minimum soil moisture were only used in model selection for two species because of missing data at many sites. Parameter abbreviations are C:N - soil carbon:nitrogen; Canopy - canopy openness; F:B - soil fungus:bacteria; Region - transect; S Soil Moist - summer minimum soil moisture; S Temp - summer maximum soil temperature for (a), (b) and summer minimum plant-height temperature for (c), (d); Snow - spring days of snow cover; W Soil Temp - winter minimum soil temperature; WHC - water holding capacity, with ‘^2’ indicating a quadratic effect.
