Positional variation in phylloplane microbial populations within an apple tree canopy
Variation in density of epiphytic yeasts, filamentous fungi, and bacteria on apple leaves collected from eight trees at nine dates for two seasons was determined with respect to three positional factors: heigh...

Fungi, leaves, and the theory of island biogeography
Species dynamics of fungi (filamentous fungi and yeasts) on apple leaves were studied within the framework of the theory of island biogeography by following “immigration” and “extinction” patterns on individua...

Fungal immigration dynamics and community development on apple leaves
Fungal immigration dynamics and community development were followed over time on sets of surface-disinfested apple leaves in the field. Immigration was defined as the arrival of viable propagules on the leaf s...

Microbial introductions to apple leaves: Influences of altered immigration on fungal community dynamics
Fungal immigration to apple leaves in the field was altered by the introduction of populations ofChaetomium globosum orAureobasidium pullulans to surface-disinfested leaves either immediately following, or 6 days...

Microbial community analysis in incompletely or destructively sampled systems
Analyses of microbial community dynamics are often constrained by the destructive, indirect, and incomplete nature of most sampling techniques. These methodological constraints compel assumptions that are rare...
