Notably, daily mean ENT abundance in dry sand was significantly correlated to tidal range (Pearson's r = 0.66, p < 0.0001), and dry sands collected during spring tides had significantly higher mean ENT than sands collected during neap tides (Student's t test, p < 0.001).
In contrast to dry sand, daily mean ENT abundance in wet sand was not correlated to tidal range, and only weakly related to air temperature (r = −0.31, p = 0.08) and previous 48 h precipitation (r = 0.32, p = 0.07).
Duplicate samples of sand were collected 0.5 m apart by using sterile 50 mL Falcon tubes to take small cores of approximately 5 cm in length/depth; wet sand was collected at the water line and dry sand at the mean high tide line.
Pearson's correlation coefficients and stepwise selection of best-fit Multiple Linear Regression models were calculated using R. Two multiple linear regression models were built using stepwise selection to predict the dependent variable of mean ENT in water and in dry sand.
As such, daily mean ENT for water, wet sand, and dry sand were used for correlation and multiple linear regression analyses.
The water-saturated sand slugs cause significantly higher deflections compared to the dry sand slugs having the same mean slug velocity and we demonstrate that this enhanced deflection is due to the larger mass of the water-saturated slugs.
We have used small amounts of biochar that equal 0, 0.5, 1, 2, 4 and 8%, which means that 1% describes a mixture of 1 g dry biochar with 99 g dry sand.
Daniel crawled toward dry sand, struggling.
* Apply meat tenderizer, vinegar or dry sand.
Without any water, sand flows; a perfectly dry sand castle would collapse into a heap.
