The analysis complements the results of previous articles by Saez and Gonz\u00e1lez-Olivares [1999] and Arancibia-Ibarra and Gonz\u00e1lez-Olivares [2015] discussing Holling\u2013Tanner models which incorporate a weak Allee effect. The extended model exhibits rich dynamics and we prove the existence of separatrices in the phase plane separating basins of attraction related to coexistence and extinction of the species. We also show the existence of a homoclinic curve that degenerates to form a limit cycle and discuss numerous potential bifurcations such as saddle-node, Hopf, and Bogdanov\u2013Takens bifurcations. <\/jats:p>","DOI":"10.1142\/s0218127419300325","type":"journal-article","created":{"date-parts":[[2019,10,16]],"date-time":"2019-10-16T06:46:35Z","timestamp":1571208395000},"page":"1930032","source":"Crossref","is-referenced-by-count":37,"title":["A Holling\u2013Tanner Predator\u2013Prey Model with Strong Allee Effect"],"prefix":"10.1142","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9725-7029","authenticated-orcid":false,"given":"Claudio","family":"Arancibia-Ibarra","sequence":"first","affiliation":[{"name":"School of Mathematical Sciences, Queensland University of Technology, GPO Box 2434, GP Campus, Brisbane, Queensland 4001, Australia"},{"name":"Facultad de Educaci\u00f3n, Universidad de Las Am\u00e9ricas, Av.
