In our view this pattern of recolonization from groups in adjacent areas is a closer approximation of dynamics of forager groups in space than is randomized repopulation from any group in the grid regardless of distance.
Meanwhile, the change of grid distance between convection cores can be seen from Δ1.7 to Δ0.87 in the whole area.
The sampling design consists of 5500 clusters with a grid distance of 3.89 km and every cluster consists of a square of 200 m length.
For each cell of the image grid, the distance between the center of the grid cell and the center of the image was determined (red vectors in Fig. 2A).
(A ) View from above the arena used to record locomotor activity and quantify grid crossings, with example tracks of individual mice from the noted conditions recorded for 30 min. (B ) Summary graphs of distance travelled and grid coverage from mice injected with saline, Drd1 agonist SKF 81297, or Drd2 agonist quinpirole.
(b) Grid cell size as a function of distance for both models.
Draw a top view diagram of the area, with each square on the grid paper representing a specific amount of distance, such as "1 square = 1 square foot".
For each dataset the coordinates of the station (or point of the reanalysis grid), the distance from the Vesuvius, the selected period, the acquisition frequency and the distance between the vertical layers are reported.
The break-even grid distance of 113 km is a strong restriction for an off-grid energy system, although the assumed specific cost of a grid-extension of €864.92/km·a [14] (page B-5) is averaged over normal terrain in India and therefore is higher at hilly sites like Narendra Nagar.
We simulated the effects of Argentine ant presence at neighboring grid squares, distance to development, presence of the native winter ant Prenolepis imparis, and other habitat and climate variables, and used these models to simulate invasion over many decades.
