Abstract

fetched live from OpenAlex

Predator-prey interactions are fundamental components of ecological systems, and spatial heterogeneity in the environment significantly influences their dynamics. This study investigates such types of spatially heterogeneous environments using local and nonlocal models. Initially, we scrutinize a local model incorporating the Allee effect and hunting cooperation among predators, laying the groundwork for understanding system dynamics. Subsequently, the nonlocal interaction captures spatial heterogeneity effects, enriching our comprehension of ecosystem dynamics. Significant ecological phenomena, such as the emergence of traveling waves, highlight the complex interactions between predator and prey populations. Extensive numerical simulations explore a range of solution categories including spatiotemporal chaos at low prey diffusion rate, shedding light on the spatial interaction of the prey-predator populations. We have discussed the patterns behind the traveling wave solutions for different parametric combinations and how Turing instability identifies such patterns. Nevertheless, we identify the traveling waves connecting two equilibrium points directly or indirectly through a stable limit cycle or saddle points.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
