Temporal and spatial dynamics of the invasive red king crab and native brachyuran and anomuran larvae in Norwegian waters
This study investigates the temporal and spatial patterns of larval stages of the invasive red king crab Paralithodes camtschaticus (RKC) and co-existing native brachyurans and anomurans in a Norwegian fjord. It is one of few field studies describing the larval stage of native and invasive brachyura...
