Introductory lesson to generate range maps for butterfly-host plant interactions and predict distributional shifts using publicly available biodiversity data and data science tools
bioclim models with pseudo-absence points can demonstrate considerable dependence on which points are actually sampled as background (i.e. "absence") points. Need to run multiple replicates of the models, re-sampling the pseudo-absence points between replicates. Combine the results:
for probabilities, do summation divided by number of replicates
for threshold, make composite with probability of presence (based on individual models' threshold) in ~90% of models
