This work addresses the challenge of eradicating an invasive predator population in an environment that varies seasonally - a topic of increasing relevance in ecological management and conservation biology. The problem is approached through a general prey-predator framework that incorporates nonlocal reaction terms, local diffusion and time-periodic coefficients, allowing us to capture the complex dynamics of such systems.
Our research emphasizes the effectiveness of selective control strategies - applied either directly to the predator population or indirectly through their prey - in achieving long-term eradication. We establish criteria for successful eradication, formulated in terms of the sign of the principal eigenvalue of a non-self-adjoint parabolic operator. As part of our analysis, we also compare the efficiency and feasibility of different types of controls.
These findings contribute to a deeper understanding of species management in dynamic reaction-diffusion ecosystems and provide a foundation for developing more refined, ecologically informed intervention strategies in future work.
