arbuscular mycorrhizal fungi
Fungal symbionts that form specialized structures (arbuscules, vesicles) within plant root cells and are important for nutrient exchange
community composition
The identity and relative abundance of species within an ecological community
dark septate endophytes
A group of fungal endophytes characterized by dark-pigmented, septate hyphae that commonly colonize plant roots and can increase under environmental stress
indicator species
Taxa that are significantly associated with particular habitat conditions and can be used to assess ecosystem state or restoration success
phylogenetic diversity
A measure of the evolutionary history represented in an ecological community, calculated as the sum of branch lengths connecting species in a phylogenetic tree
metabolic rate distribution over individuals
Distribution of metabolic rates over individuals in a community, obtained by summing over abundance
species accumulation curve
Plot showing cumulative number of species discovered as a function of sampling effort, used to assess sampling completeness
plant disease
Percentage of leaf area affected by pathogen symptoms including powdery mildew, rust, and other fungal diseases
