Communities are identified using Gaussian Mixture Modeling with the mclust package in R.
Clustering is done on relative abundance-weighted habitat suitability through time.
The top map shows 2018 community distributions
and the bottom map shows projected future shifts.
Communities with similar relative abundance-weighted habitat suitability across the two maps share the same color.The buttons on the left correspond to each community mapped on the right.
Select a button to learn how the abundance-weighted habitat suitability for each species
is predicted to change across time within the selected community.
The figure on the bottom left will then show the mean change in abundance-weighted habitat suitability
for species predicted to see the largest change in
abundance-weighted habitat suitability within the selected community.
Compositional Changes in Communities
To see how the species composition is changing select a community below.
The abundance-weighted habitat suitability of species within each community is also expected to change. For example, certain species might become more
abundant, whereas other species may become rarer, even though overall the community composition indicates that this future community is similar enough to
the current community to be considered the same.
The figure below shows mean change in abundance-weighted habitat suitability from present for species within the selected
community. Only species with the highest predicted change in abundance-weighted habitat suitability are shown. Units depend on the
taxa: estimates of abundance per plot (counts, basal area, or cover)
