Simulation of movement that potentially maximizes assessment, presence, and defense in territorial animals with varying movement strategies

摘要: Brown et al. (2011) published a simulation model that could be used as sub-model for larger simulations (e.g. at the population level) to investigate how individuals may optimize territorial movements while sampling territory resources. In their example, male fish guards against neighbor males interacting with mate (the resource), but all employed same, matching (relative-movement), strategies. We contrast results of this allows use independent movement Using mean encounter rate (MER) between individuals, and coefficient variation (CV), metrics, we found in smallest territories, aspects (length-to-width ratios), variant relative-movement strategies are not determinant maximizing presence (male–neighbor interactions) or minimizing its variation. Directed (low-movement angle strategies) appears accomplish this, regardless behavior relative others. contrast, small directed does presence, aspect, mismatched typically optimal. Social (within male–female is more complex. again general pattern low-movement strategy was However, steps sizes (distances decisions) became influential. Once again, take on lesser importance smaller territories. Concerning optimizing strategies, matching, no strategy, optimal except small, high conclude prudent approach future efforts will utilize “top-down approach” by only removing complexity involving varying from if they unnecessary situation simulated.
