Data from: Complementarity in spatial subsidies of carbon associated with resource partitioning along multiple niche axes

This dataset includes data from surveys of mussel beds, destructive sampling to quantify abundances, measurements of lengths and masses, measurements of annual growth rates, and carbon and nitrogen percentages and stable isotope values. Samples are from mussel beds at four sites on the South Island of New Zealand: Blue Duck (42.28º S, 173.75° E) and Box Thumb (43.58° S, 172.78° E) on the east coast and Nile River (41.90° S, 171.44° E) and Nine Mile (42.34° S, 171.26°E) on the west coast. Mussels were surveyed and sampled at each site at three tidal elevations: 1.0, 1.5, and 2.0 m above the lowest astronomical tide. Mussel species included Perna canaliculus, Mytilus galloprovincialis, Aulacomya maoriana, and Xenostrobus pulex, all of which coexist at these sites.
