First, value ranges for the individual spreading speeds of each species are established via comparison with classical Fisher-KPP equations. It is then studied whether spreading is single- or multiple-speed, the selection mechanism of the spreading speed being also investigated.<br class="zbmathjax-paragraph">It is determined that multiple spreading speeds cannot occur and the (single) spreading speed coincides with the minimal speed of the traveling waves. Sufficient conditions for the linear selection of the minimal speed of the traveling waves are then established via linearization, followed by a comparison argument. Conversely, a novel, general condition for the nonlinear selection of the minimal wave speed in terms of the relation between the decay rate and the wave speed is established via a limiting argument for lower solutions. All theoretical results are then validated via comprehensive numerical simulations.<div class="reviewer"> Reviewer: <a href="/authors/?q=rv%3A12667">Paul Georgescu (Iaşi)</a></div> <div class="clearfix"></div></div> <div class="clear"></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A92D25" title="MSC2020">92D25</a> </td> <td class="space"> Population dynamics (general) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A35C07" title="MSC2020">35C07</a> </td> <td class="space"> Traveling wave solutions </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A35K57" title="MSC2020">35K57</a> </td> <td class="space"> Reaction-diffusion equations </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Aspreading+speed">spreading speed</a>; <a href="/?q=ut%3Atraveling+waves">traveling waves</a>; <a href="/?q=ut%3Alinear+selection">linear selection</a>; <a href="/?q=ut%3Anonlinear+selection">nonlinear selection</a>; <a href="/?q=ut%3Aminimal+wave+speed">minimal wave speed</a></div> <!-- Modal used to show zbmath metadata in different output formats--> <div class="modal fade" id="metadataModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">Cite</h4> </div> <div class="modal-body"> <div class="form-group"> <label for="select-output" class="control-label">Format</label> <select id="select-output" class="form-control" aria-label="Select Metadata format"></select> </div> <div class="form-group"> <label for="metadataText" class="control-label">Result</label> <textarea class="form-control" id="metadataText" rows="10" style="min-width: 100%;max-width: 100%"></textarea> </div> <div id="metadata-alert" class="alert alert-danger" role="alert" style="display: none;"> <!-- alert for connection errors etc --> </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary" onclick="copyMetadata()">Copy to clipboard</button> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <div class="functions clearfix"> <div class="function"> <!-- Button trigger metadata modal --> <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 07922168" data-ciurl="/ci/07922168" data-biburl="/bibtex/07922168.bib" data-amsurl="/amsrefs/07922168.bib" data-xmlurl="/xml/07922168.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/07922168.pdf" title="Zbl 07922168 as PDF">Review PDF</a> </div> <div class="fulltexts"> <span class="fulltext">Full Text:</span> <a class="btn btn-default btn-xs" type="button" href="https://doi.org/10.1016/j.jmaa.2024.128678" aria-label="DOI for “Spreading speed and traveling wave for a reaction-diffusion system with nonlinear competition”" title="10.1016/j.jmaa.2024.128678">DOI</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">Fang, J.; Zhao, X.
