SBC LTER: BEACH: Invertebrate community structure and ecosystem functions of 24 sandy beach sites

These data result from a survey of 24 sandy beach sites in Santa
Barbara and Ventura Counties in 2017 and 2018. We quantified
marine macrophyte wrack subsidies, macroinvertebrates, and five
ecosystem functions on three replicate transects at each site in
order to elucidate the role of marine wrack subsidies on recipient
ecosystem community structure and functioning. We also measured
shorebirds at each site on three replicate survey days. Data are
contained in four tables: 1) wrack cover and invertebrate
community data by transect for each site used in our PiecewiseSEM
model, 2) wrack cover and ecosystem function data by transect for
each site used in our ecosystem multifunctionality estimate, 3)
invertebrate species abundance and biomass by transect for each
site, and 4) shorebird species abundance by survey date for each
site.
