Digital recording and spectral analysis of alarm vocalizations to quantify entropy and goodness of pitch as measures of call structure and acoustic properties.
Mixed-effects modeling approach to partition phenotypic variance into genetic and environmental components using pedigree information and repeated measures data.
Statistical method using continuous two-phase models to identify the age at which body mass growth stabilizes at adult levels in golden-mantled ground squirrels.
Linear mixed effect models to estimate individual body mass at key seasonal transition points, accounting for day-of-year effects and random variation among years, sites, and individuals. Provides sta...
RASTER-based spatial analysis to quantify multiple metrics of anthropogenic disturbance including distance to infrastructure and proportion of impervious surfaces within species-specific buffer zones.
A standard comparative method that controls for evolutionary relationships among species by analyzing evolutionary changes along phylogenetic branches rather than raw species values. Uses software to ...
Mathematical method for calculating relative dominance ranks from pairwise interaction outcomes that is tolerant of missing data and accounts for group size variation.
Use of remote sensing data to determine snowmelt timing and map marmot colony boundaries. Combines satellite imagery analysis with ground-truthed colony locations to quantify seasonal and habitat vari...
