Figures & data

Table 1. Summary and description of agent movement rules.

Figure 1. Examples of spatially discrete (either cell centered [a] or nodal [c]) and continuous (b, d) movement within either a simplified 2-D rectangular and triangular mesh grid. Examples of how agents within the models sensed their environment; (e) in adjacent upstream cells (e.g., Padgett et al. Citation2020b); (f) within cells that fell on the perimeter of a sensory circle (e.g., Tan et al. Citation2018); (g) at a fixed number of points (black crosses) that fell on the perimeter of a sensory ovoid (e.g., Goodwin et al. Citation2006, Citation2014, Citation2023); (h) at all nodes (black crosses) that fell within a sensory semi-circle oriented in line with the swim direction of the agent (e.g., Zielinski et al. Citation2018). Note, all examples show grid and sensory points in two dimensions for simplicity.
