We have studied a predator\u2013prey interaction system with mutually interfering predator by considering additional food and Crowley\u2013Martin functional response (CMFR) for both the reaction\u2013diffusion model and associated spatially homogeneous system. The local stability analysis ensures that as the quantity of alternative food decreases, predator-free equilibrium stabilizes. Moreover, we have also obtained a condition providing a threshold value of additional food for the global asymptotic stability of coexisting steady state. The nonspatial model system changes stability via transcritical bifurcation and switches its stability through Hopf-bifurcation with respect to certain ranges of parameter determining the quantity of additional food. Conditions obtained for local asymptotic stability of interior equilibrium solution of temporal system determines the local asymptotic stability of associated diffusive model. The global stability of positive equilibrium solution of diffusive model system has been established by constructing a suitable Lyapunov function and using Green\u2019s first identity. Using Harnack inequality and maximum modulus principle, we have established the nonexistence of nonconstant positive equilibrium solution of the diffusive model system. A chain of patterns on increasing the strength of additional food as spots[Formula: see text][Formula: see text][Formula: see text]stripes[Formula: see text][Formula: see text][Formula: see text]spots has been obtained. Various kind of spatial-patterns have also been demonstrated via numerical simulations and the roles of predator interference and additional food are established. <\/jats:p>","DOI":"10.1142\/s0218127420501023","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T09:25:33Z","timestamp":1593595533000},"page":"2050102","source":"Crossref","is-referenced-by-count":18,"title":["Exploring Complex Dynamics of Spatial Predator\u2013Prey System: Role of Predator Interference and Additional Food"],"prefix":"10.1142","volume":"30","author":[{"given":"Vandana","family":"Tiwari","sequence":"first","affiliation":[{"name":"Gandhi Smarak PG College, Samodhpur, Jaunpur-223102, U.P., India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jai Prakash","family":"Tripathi","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Central University of Rajasthan, Bandarsindri, Kishangarh 305801, Ajmer, Rajasthan, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Debaldev","family":"Jana","sequence":"additional","affiliation":[{"name":"Department of Mathematics and SRM Research Institute, SRM University, Kattankulathur-603 203, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satish Kumar","family":"Tiwari","sequence":"additional","affiliation":[{"name":"Department of Mathematics, B.I.T., Sindri, Dhanbad-828123, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1210-7804","authenticated-orcid":false,"given":"Ranjit Kumar","family":"Upadhyay","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Computing, Indian Institute of Technology (ISM), Dhanbad 826004, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2020,7,1]]},"reference":[{"key":"S0218127420501023BIB001","doi-asserted-by":"publisher","DOI":"10.1086\/319933"},{"key":"S0218127420501023BIB002","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/657286"},{"key":"S0218127420501023BIB003","doi-asserted-by":"publisher","DOI":"10.1007\/s12080-010-0073-1"},{"key":"S0218127420501023BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/j.mbs.2011.12.005"},{"key":"S0218127420501023BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/j.ecocom.2014.05.005"},{"key":"S0218127420501023BIB006","first-page":"1530","volume":"73","author":"Berryman A.","year":"1992","journal-title":"Ecol.
