Concepts

The ratio of leaf area to dry mass, often associated with dry conditions as it reduces surface area and water loss from the leaf

Net production of plant biomass above ground surface measured as standing crop minus losses to herbivores

Genomic bins reconstructed from metagenomic sequencing data representing individual microbial taxa

Plant characteristics that reflect ecological strategies, including specific leaf area and leaf dry matter content

Measure of soil acidity/alkalinity that may influence plant phenotype expression

Measurable morphological and physiological characteristics of organisms that influence ecological performance

Standardized measure of water deficit calculated using the Standardized Precipitation Evapotranspiration Index (SPEI) over 12-month periods

The extent to which fungal symbionts colonize plant tissues, measured as percentage of tissue colonized

An approximation of non-water stressed evapotranspiration calculated using energy-only methods from net radiation estimates

The relative proportions of essential macronutrients (proteins, lipids, carbohydrates) in pollen samples

The identification of species from environmental DNA samples using target capture sequencing and database matching

Distinct phases of bee flight period: emergence from nests, timing of peak abundance of foragers, and senescence

The percentage of ground area covered by a particular plant species when viewed from above

Maximum temperature of warmest month, capturing seasonality in contrast to average annual temperatures

Climatic index reflecting atmospheric pressure differences between Iceland and Azores

Energy content of plant materials measured as calories per gram of ash-free oven-dry weight

Activity of enzymes secreted by soil microorganisms that catalyze decomposition of organic matter and provide assimilable carbon and nitrogen compounds

Total amount of living microbial tissue in soil measured as carbon and nitrogen content

Raster representation of terrain elevation used to derive topographic attributes like slope and aspect
