Variability of competition at scales of 10(1), 10(3), 10(5), and 10(6) m: encrusting arctic community patterns
Variability in interference competition was studied in benthic marine communities of the arctic and subarctic Atlantic intertidal and shallow subtidal zones. We sampled multiple square-metre quadrats at distances of 10(1). 10(3) and 10(5) m apart around the high polar island of Spitsbergen (Svalbard...

Variability in interference competition was studied in benthic marine communities of the arctic and subarctic Atlantic intertidal and shallow subtidal zones.
