Concepts

Normalized Difference Vegetation Index, derived from satellite imagery to estimate vegetation greenness and photosynthetic activity

Network statistics that quantify the importance or influence of individuals within social networks, including degree, closeness, betweenness, and eigenvector centrality

The accuracy of predicted values using root mean square error to assess model performance

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

The ratio of dry root weight to total dry plant weight, used as an indicator of soil nutrient availability with higher values indicating nutrient-poor conditions

A model selection criterion that balances goodness of fit with model complexity by penalizing models with more parameters

Statistical measure of repeatability that tests individual consistency of a continuous variable by comparing within-subject and between-subject variation

Measure of the relative contribution of each predictor variable obtained by calculating mean decrease in mean square error

A statistic derived from information theory that quantifies individuality by calculating inter-individual variation relative to intra-individual variation

A measure of niche overlap calculated as SI = 1 - (1/2) Σᵢ |pᵢₖ - pⱼₖ| where values approach 1 when resource use curves coincide perfectly and approach 0 when they don't overlap

A quantitative measure of uncertainty about an outcome of a draw from a probability distribution

A method for calculating dominance based on an individual's relative number of wins or losses that is tolerant of missing pair-wise interactions and weights wins highly

A measure comparing the proportion of prey in predator diet to proportion in environment to detect selection or avoidance

Measure of how effectively a sampling method captures target organisms relative to processing time and effort

Constancy index that distinguishes between complete constancy, random transitions, and complete inconstancy

Harmonic mean of precision and recall used to evaluate classification model performance

Statistical measure of effect size calculated as the ratio of treatment to control group means

A standardized measure of synchrony that ranges between 0 and 1, quantifying overlap of activity duration for each individual relative to the population

Statistical method to extract individual behavioral profiles accounting for random effects structure

Association index calculated as the ratio of observations of individuals a and b seen together over the sum of observations of them seen together plus times seen separately

β-diversity metric used to quantify interaction turnover between successive weekly networks

A dimensional ratio calculated from minimum bounding rectangles to quantify the shape characteristics of pond polygons

Standardized measure of abundance calculated as number of individuals caught per unit of sampling time or effort
