Parasites, on the other hand, have the ability to change both the qualitative and quantitative dynamics of its host population. In recent times, researchers are showing growing interest in formulating models that integrate both the ecological and epidemiological aspects. The present paper deals with the effect of alternative food on a predator\u2013prey system with disease in the predator population. We show that the system, in the absence of alternative food, exhibits different dynamics viz. stable coexistence, limit cycle oscillations, period-doubling bifurcation and chaos when infection rate is gradually increased. However, when predator consumes alternative food coupled with its focal prey, the system returns to regular oscillatory state from chaotic state through period-halving bifurcations. Our study shows that alternative food may have larger impact on the community structure and may increase population persistence. <\/jats:p>","DOI":"10.1142\/s0218127416501479","type":"journal-article","created":{"date-parts":[[2016,8,30]],"date-time":"2016-08-30T09:32:56Z","timestamp":1472549576000},"page":"1650147","source":"Crossref","is-referenced-by-count":15,"title":["Role of Alternative Food in Controlling Chaotic Dynamics in a Predator\u2013Prey Model with Disease in the Predator"],"prefix":"10.1142","volume":"26","author":[{"given":"Krishna Pada","family":"Das","sequence":"first","affiliation":[{"name":"Department of Mathematics, Mahadebananda Mahavidyalaya, Barrackpore, Kolkata-700120, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nandadulal","family":"Bairagi","sequence":"additional","affiliation":[{"name":"Centre for Mathematical Biology and Ecology, Department of Mathematics, Jadavpur University, Kolkata-700032, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prabir","family":"Sen","sequence":"additional","affiliation":[{"name":"Centre for Mathematical Biology and Ecology, Department of Mathematics, Jadavpur University, Kolkata-700032, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2016,8,30]]},"reference":[{"key":"S0218127416501479BIB001","doi-asserted-by":"publisher","DOI":"10.2307\/2265634"},{"key":"S0218127416501479BIB002","doi-asserted-by":"publisher","DOI":"10.1038\/364229a0"},{"key":"S0218127416501479BIB003","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.1986.0072"},{"key":"S0218127416501479BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtbi.2007.05.005"},{"key":"S0218127416501479BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/j.ecocom.2015.01.002"},{"key":"S0218127416501479BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/0040-5809(76)90040-X"},{"key":"S0218127416501479BIB007","doi-asserted-by":"publisher","DOI":"10.1093\/imammb\/dqm005"},{"key":"S0218127416501479BIB008","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3800(00)00350-1"},{"key":"S0218127416501479BIB009","doi-asserted-by":"publisher","DOI":"10.1088\/0951-7715\/10\/5\/004"},{"key":"S0218127416501479BIB010","doi-asserted-by":"publisher","DOI":"10.1016\/j.ecocom.2009.03.003"},{"key":"S0218127416501479BIB011","doi-asserted-by":"publisher","DOI":"10.1142\/S0218339010003391"},{"key":"S0218127416501479BIB012","doi-asserted-by":"publisher","DOI":"10.1086\/424681"},{"key":"S0218127416501479BIB013","doi-asserted-by":"publisher","DOI":"10.1890\/0012-9658(2006)87[2832:TIOPMA]2.0.CO;2"},{"key":"S0218127416501479BIB014","doi-asserted-by":"publisher","DOI":"10.1007\/BF01238191"},{"key":"S0218127416501479BIB015","doi-asserted-by":"publisher","DOI":"10.1086\/283389"},{"key":"S0218127416501479BIB016","doi-asserted-by":"publisher","DOI":"10.1086\/653669"},{"key":"S0218127416501479BIB017","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4612-1140-2"},{"key":"S0218127416501479BIB018","doi-asserted-by":"publisher","DOI":"10.2307\/1940591"},{"key":"S0218127416501479BIB019","doi-asserted-by":"publisher","DOI":"10.1098\/rsif.2005.0042"},{"key":"S0218127416501479BIB020","doi-asserted-by":"publisher","DOI":"10.1016\/j.tpb.2004.06.010"},{"key":"S0218127416501479BIB021","doi-asserted-by":"publisher","DOI":"10.1080\/08898480600788568"},{"key":"S0218127416501479BIB022","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.es.25.110194.002431"},{"key":"S0218127416501479BIB023","doi-asserted-by":"publisher","DOI":"10.1093\/imammb\/dqn017"},{"key":"S0218127416501479BIB024","doi-asserted-by":"publisher","DOI":"10.2307\/5338"},{"key":"S0218127416501479BIB025","doi-asserted-by":"publisher","DOI":"10.1038\/46540"},{"key":"S0218127416501479BIB026","first-page":"066","volume":"69","author":"Jaewook J.","year":"2004","journal-title":"Phys.
