To quantify any spatial or temporal variability in cockle densities with respect to in situ GMA biomass in Yaquina Bay, OR, we conducted field surveys during consecutive daytime low tides (<0.46 m MLLW) in both June and August 2014, which provided a comparison between early and late summer. This dataset contains all data collected during those field surveys. This dataset is associated with the following publication: Lewis, N., and T. DeWitt. Effect of Green Macroalgal Blooms on the Behavior, Growth, and Survival of Cockles (Clinocardium nuttallii) in Pacific NW Estuaries. MARINE ECOLOGY PROGRESS SERIES. Inter-Research, Luhe, GERMANY, 582: 105-120, (2017).

To identify the factors of green macroalgae (GMA) accumulation that cause cockles to rapidly emerge from the sediment, we conducted a series of laboratory experiments to isolate the effects of anoxia, surficial pressure/barrier, GMA presence, and the interaction of GMA presence and a surficial pressure/barrier on the emergence behavior of buried cockles. We quantified the emergence response of cockles in each of these five treatments with six replicates (emergent proportion of cockles tank-1) per treatment (n = 30 tanks). After the start of each trial, subjects were examined at 0.5, 1, 2, 4, 6, and 8 hrs for changes in burial depth; those that were partially or completely exposed at the sediment surface were considered to have exhibited an emergence response.

We carried out a lab experiment in which we exposed cockles to a range of air temperatures to simulate the physiological rigors of exposure to sunlight and air at the sediment surface during daytime low tides. Cockles were subjected to twelve different temperature (6, 14, 21, 30, 34, 38 ± 1.0 °C) x time (2, 4 hrs) treatments within temperature-controlled chambers, representing the temperature and exposure durations regularly observed on Yaquina Bay mid-intertidal flats during daytime low tides in the summer. This dataset contains all data collected during that lab experiment. This dataset is associated with the following publication: Lewis, N., and T. DeWitt.

These data, which support a paired USGS publication, describe the efficacy of several management practices for reducing the presence of herring gulls in the nesting colonies of Common Terns. This data was collected on Poplar Island, located in the Chesapeake Bay portion of Maryland.

This dataset describes responses to flushes by surveyors and predators for mallard and gadwall hens nesting on the Grizzly Island Wildlife Area, Suisun Marsh, California in 2015 through 2018. It includes the start time and duration of recesses, as well as the cause of recess initiation and responses of hens to various trapping activities at the nest site.
