Wolf environmental DNA in southeast Alaska

Data to demonstrate multivariate Tweedie GAM for spatial analysis

Usage

data(southeast_alaska_wolf)

Value

A data long-form data frame

Details

Data sufficient to demonstrate how to use a Tweedie GLM to provide inference about proportions e.g. in food habits analysis, where the model output is processed to represent a multivariate logit Tweedie model.

Specifically includes environmental DNA sampling of wolf scats obtained in Southeast Alaska.

• Latitude Latitude for scat sample

• Longitude Longitude for scat sample

• group prey groupings from eDNA smaples

• Response relative read abundance calculated as the mean proportion of DNA sequence reads from each species among samples from a given scat
