Most of the metapopulation models assume exponential growth of the local populations and few works have explored the role of cooperation in fragmented ecosystems. In this letter, we study the dynamics and the bifurcation scenarios of a minimal, two-patch metapopulation Turing-like model given by nonlinear differential equations with an autocatalytic reaction term together with diffusion. We also analyze the extinction transients of the metapopulations focusing on the effect of coupling two local populations undergoing delayed transition phenomena due to ghost saddle remnants. We find that increasing diffusion rates enhance the delaying capacity of the ghosts. We finally propose the saddle remnant as a new class of transient generator mechanism for ecological systems.<\/jats:p>","DOI":"10.1142\/s0218127410026460","type":"journal-article","created":{"date-parts":[[2010,4,26]],"date-time":"2010-04-26T08:26:17Z","timestamp":1272270377000},"page":"1261-1268","source":"Crossref","is-referenced-by-count":11,"title":["ON THE METAPOPULATION DYNAMICS OF AUTOCATALYSIS: EXTINCTION TRANSIENTS RELATED TO GHOSTS"],"prefix":"10.1142","volume":"20","author":[{"given":"JOSEP","family":"SARDANY\u00c9S","sequence":"first","affiliation":[{"name":"Instituto de Biolog\u00eda Molecular y Celular de Plantas, Consejo Superior de Investigaciones Cient\u00edficas-UPV, Ingeniero Fausto Elio s\/n, 46022 Val\u00e8ncia, Spain"},{"name":"Complex Systems Lab (ICREA-UPF), Barcelona Biomedical Research Park (PRBB), Dr. Aiguader 88, 08003 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ERNEST","family":"FONTICH","sequence":"additional","affiliation":[{"name":"Departament de Matem\u00e0tica Aplicada i An\u00e0lisi, Universitat de Barcelona, Gran Via de les Corts Catalanes 585, 08007 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,5,2]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.5962\/bhl.title.7313"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1007\/s00040-005-0817-x"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtbi.2004.12.015"},{"key":"rf4","series-title":"Oxford Series in Ecology and Evolution","doi-asserted-by":"crossref","DOI":"10.1093\/oso\/9780195086218.001.0001","volume-title":"Cooperation Among Animals.
