Fig. 2From: Path analyses of cross-sectional and longitudinal data suggest that variability in natural communities of blood-associated parasites is derived from host characteristics and not interspecific interactionsThe best path analysis model for predicting the temporal changes in the community composition of parasites as determined by the longitudinal dataset (model 48 in Additional file 1: Table S1). Arrows represent direct and indirect influences. Numbers on the arrows are standardized path coefficients, representing the relative strength of the given effect (β/SE), which is also reflected by the arrow width. a–e illustrate the directions of the most influential (|β/SE| > 1) direct effects. The dashed arrows represent additional relationships that are included only in the second and third best models (models 49 and 46, respectively, in Additional file 1: Table S1). Asterisks denote relationships that were not included in the second and third best modelsBack to article page
