Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. Where those designations appear in this book, and Addison-Wesley was aware of a trademark claim, the designations have been printed with initial capital letters or in all capitals....
The binary interaction matrix is available from Github (github.com/jvancau/interactiondata). With this information, a matrix was constructed based on Bray–Curtis dissimilarity calculated with the vegdist function of the vegan package in R [83]. To compare the phenotypic composition with the ...
