SppTrend: Analyzing Linear Trends in Species Occurrence Data
Provides a comparative framework to detect species-specific spatial and
thermal responses to climate change using opportunistic occurrence data. Species
temporal trends in geographic position (via Earth-Centred Earth-Fixed vector
analysis) and environmental variables (temperature and elevation) are contrasted
against the overall trend of the complete dataset, allowing classification of
species into ecologically interpretable response categories. Approach described
in Lobo et al. (2023) <doi:10.1002/ece3.10674>.
