Data for: Seagrass increases seasonal variability in nekton but not predation intensity in mid-latitude estuaries

We sampled nekton, eelgrass, and predation intensity (loss of baits over 24 h) in summer 2016 and spring 2017 to test hypotheses about the seasonality of nekton and food web interactions in structured and unstructured low intertidal soft sediment habitats. The data sets provide the GPS locations, eelgrass size and density, nekton size and density, and predation intensity. We found that nekton differed more seasonally in eelgrass than bare habitat, consistent with seasonally-variable structure. Predation intensity was higher in summer than spring but did not differ by habitat. Some eelgrass-associated species increased with eelgrass abundance seasonally, but grass shrimp declined, likely due to intraguild predation. The morphotype of eelgrass and geographic proximity did not explain differences among the five sites in terms of nekton assemblages and seasonality.
