First, we examine the existence and stability of possible equilibria, as well as the boundedness of the system. Specifically, the asymptotic dynamics near the origin is performed using a blow-up transformation. Furthermore, various bifurcations are explored, including saddle-node bifurcation, supercritical and subcritical Hopf bifurcations, Bautin bifurcation and Bogdanov\u2013Takens bifurcations of codimensions 2 and 3. The system exhibits diverse dynamical phenomena such as the emergence of a semi-stable limit cycle, the coexistence of a homoclinic loop and a limit cycle and the coexistence of two distinct limit cycles. In particular, with a specific set of parameters, two semi-stable limit cycles appear simultaneously, indicating that the system enters a dual-critical state. Finally, numerical simulations are carried out to validate the theoretical results.<\/jats:p>","DOI":"10.1142\/s0218127425501913","type":"journal-article","created":{"date-parts":[[2025,10,14]],"date-time":"2025-10-14T07:35:04Z","timestamp":1760427304000},"source":"Crossref","is-referenced-by-count":0,"title":["Dynamics on a Leslie\u2013Gower Model with Simplified Holling IV Function Response, Allee Effect and Predator Cannibalism"],"prefix":"10.1142","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-2597-3169","authenticated-orcid":false,"given":"Da","family":"Wang","sequence":"first","affiliation":[{"name":"School of Science, China University of Geosciences (Beijing), Beijing 100083, P.
