Abstract
Abstract The management of predator-prey systems, particularly those with discontinuous harvesting, plays a crucial role in maintaining ecological balance and ensuring the sustainable use of renewable resources. Despite the importance of this topic, the dynamics of diffusive predator-prey models with discontinuous harvesting have not been thoroughly explored in existing literature. This study addresses this gap by investigating a diffusive predator–prey model incorporating a discontinuous harvesting function. We establish the existence and boundedness of solutions, analyse the conditions under which a positive steady state is achieved, and explore the model’s stability, including global asymptotic stability and convergence in finite time. Additionally, we examine the effects of Turing instability, Hopf bifurcation, and steady-state bifurcation within the model. Numerical simulations are provided to illustrate the impact of discontinuous harvesting on the system’s dynamics, highlighting the practical applications of the theoretical results in fields such as pest control. The findings of this study offer valuable insights for the design of effective population management strategies in ecological and agricultural contexts.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
