Natural communities are well known to be maintained by many complex processes. Despite this, the practical aspects of studying them often require some simplification, such as the widespread assumption
Data used in the application of the multi-region community model (MRCM) to detection non-detection data collected from bird assemblages in R=8 geographically distinct areas (regions) in northern Italy
Supplementary Material 8. Supplementary Table 2. Normalized cross-feeding interactions between top cross-feeding taxa in HB and NB communities (related to Figure 4 A).
Growth rates, death rates and degradation investment vectors rij, mik and fik are made sparse by multiplying them by a vector drawn from Bernoulli(0.5). Each species can this way only take up a random
