A novel approach for in situ benthic habitat characterization
Limnology and Oceanography: Methods, EarlyView.Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.
