In order to better describe and understand the ways in which the landscape may support species movement, an increasing amount of research has focused on identification of paths or corridors that may be important in providing connectivity among habitat. The least-cost path problem has proven to be an instrumental analytical tool in this sense. A complicating aspect of such path identification methods is how to best reconcile and integrate the array of criteria or objectives that species may consider in traversal of a landscape. In cases where habitat connectivity is thought to be influenced or guided by multiple objectives, numerous solutions to least-cost path problems can exist, representing tradeoffs between the objectives. In practice though, identification of these solutions can be very challenging and as such, only a small proportion of them are typically examined leading to a weak characterization of habitat connectivity. To address this computational challenge, a multiobjective optimization framework is proposed. A generalizable multiobjective least-cost path model is first detailed. A non-inferior set estimation (MONISE) algorithm for identifying supported efficient solutions to the multiobjective least-cost path model is then described. However, it is well known that unsupported efficient solutions (which are equally important) can also exist, but are typically ignored given that they are more difficult to identify. Thus, to enable the identification of the full set of efficient solutions (supported and unsupported) to the multiobjective model, a multi-criteria labeling algorithm is then proposed. The developed framework is applied to assess different conceptualizations of habitat connectivity supporting amphibian movement in a wetland system. The results highlight the range of tradeoffs in characterizations of connectivity that can exist when multiple objectives are thought to contribute to movement decisions and that the number of unsupported efficient solutions (which are typically ignored) can vastly outweigh that of the supported efficient solutions.<\/jats:p>","DOI":"10.1371\/journal.pcbi.1008540","type":"journal-article","created":{"date-parts":[[2020,12,28]],"date-time":"2020-12-28T18:23:19Z","timestamp":1609179799000},"page":"e1008540","update-policy":"https:\/\/doi.org\/10.1371\/journal.pcbi.corrections_policy","source":"Crossref","is-referenced-by-count":6,"title":["Modeling habitat connectivity in support of multiobjective species movement: An application to amphibian habitat systems"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2159-4904","authenticated-orcid":true,"given":"Timothy C.","family":"Matisziw","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4891-822X","authenticated-orcid":true,"given":"Ashkan","family":"Gholamialam","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0968-6611","authenticated-orcid":true,"given":"Kathleen M.","family":"Trauth","sequence":"additional","affiliation":[]}],"member":"340","published-online":{"date-parts":[[2020,12,28]]},"reference":[{"issue":"5702","key":"pcbi.1008540.ref001","doi-asserted-by":"crossref","first-page":"1783","DOI":"10.1126\/science.1103538","article-title":"Status and trends of amphibian declines and extinctions worldwide","volume":"306","author":"SN Stuart","year":"2004","journal-title":"Science"},{"issue":"1","key":"pcbi.1008540.ref002","first-page":"27","article-title":"Are we in the midst of the sixth mass extinction?
