To determine whether differences in cockle density or qualitative burial depth observed during the 2014 field survey were affected by green macroalgal (GMA) mats, we conducted a field caging experiment whereby cockles were subjected to the presence or absence of simulated GMA mats for 12 weeks (July-September 2014). This dataset contains all data collected during that field experiment. 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.

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.

In order to assess the potential impact that artificial nest boxes may have on the occupation rate or physical condition of adults and chicks of little penguins (Eudyptula minor), temperature was recorded continuously from 24 August 2002 (0000 hours) for 37 days inside 7 nest boxes and in surrounding bush on Penguin Island, Western Australia.

,Data are from a laboratory experiment conducted to examine the effects of cold temperatures on egg survival of Ageneotettix deorum, the white-whiskered grasshopper which is a common rangeland pest species in the Northern Great Plains region.,Abstract from published manuscript: The effect of cold temperatures and exposure time on egg survival and hatching success were examined in the white-whiskered grasshopper, Ageneotettix deorum. Temperature treatments ranged from 4°C to -35°C, with treatment times ranging from 48 to 240 hours. Both decreasing temperatures and exposure time negatively affected egg survival, with a temperature below -25°C being lethal. Similar lethal temperatures are known for several North American grasshopper species. The relatively shallow location of A. deorum egg pods would result in increased vulnerability of eggs to cold temperatures in the absence of snow.,Resources in this dataset:,
