Spatial scale and habitat‐dependent diversity patterns in nematode communities in three seepage related sites along the Norwegian Sea margin
Abstract Assessing the relative contribution of local diversity to regional biodiversity may be the key to understanding large‐scale and even global patterns in species diversity. Here, the contribution of habitat heterogeneity of cold seeps at three spatial scales [micro‐scale (ms), macro‐scale (10...
