Spatial resolution and location impact group structure in a marine food web
Ecological processes in food webs depend on species interactions. By identifying broad-scaled interaction patterns, important information on species ecological roles may be revealed. Here, we use the group model to examine how spatial resolution and proximity influence group structure. We examine a...

We test how the group structure in the networks differ comparing (1) the regional metaweb to subregions and (2) subregion to subregion.
