Concepts

A method to test for phylogenetic signal by comparing empirical data variance to variance from randomly reshuffled species identities across trait data sets

Non-invasive wildlife monitoring technique using motion-triggered cameras to detect and photograph animals

The rate of energy expenditure for basic physiological maintenance processes, measured as CO₂ emission rate.

Method to determine the spatial origin of sound sources using arrays of microphones and signal processing techniques

Measure of how noisy or random a sound is, with pure tones having entropy values approaching negative infinity

Statistical technique used to classify observations into predefined groups based on multiple variables

Distributed network of environmental sensors measuring diverse phenomena across watershed for understanding and predicting watershed behavior

Quantitative measure of acoustic similarity between sounds, ranging from 0 to 1.0 with higher correlations indicating more similar sounds

Correlation between behavioral traits at the individual level, estimated while controlling for within-individual variation and environmental effects

The total volume of CO₂ emitted during flight trials, which reflects overall flight performance including endurance.
