Sampling community structure

WebJul 20, 2024 · In this article, we consider the problem of crawling a multiplex network to identify the community structure of a layer-of-interest. A multiplex network is one where there are multiple types of relationships between the nodes. In many multiplex networks, some layers might be easier to explore (in terms of time, money etc.). WebSampling design. Two factors, pool area and pool depth, were examined to determine their effect in rock pool community structure and functioning during early succession. Early succession was initiated through removal of biota and promoted through removal of grazers over the experimental period. Natural pools
