Concepts

Statistical approach allowing estimation of directional relationships among variables and comparison of direct versus indirect effects

The degree to which values at nearby locations are correlated, used to assess spatial clustering in disease patterns

Statistical measure of variation used to quantify family-guild variation and compare across different taxonomic groups

Transparent chambers commonly used in climate change experiments to raise air and soil temperature in remote areas by creating a passive warming effect

Statistical method to compare species richness across samples by generating accumulation curves based on individual encounters

Systematic differences in detection or capture probability among species or groups due to sampling method

Sampling methods that result in the death of collected organisms, potentially affecting population abundance and community structure

Mathematical moments describing trait distributions including mean, variance, skew and kurtosis that characterize central tendency, spread, asymmetry and tail behavior

Statistical method to identify correlations between species traits and environmental variables

Method of covering flowers with mesh bags to prevent pollinator access and allow nectar accumulation for sampling

Scientific research conducted in whole or in part by amateur or nonprofessional scientists
