But in some cases, not all offspring are created equal. In the February edition of Field Talk, Jaboury Ghazoul of the Swiss Federal Institute of Technology in Zurich, Switzerland, describes how some species of trees invest resources in seeds that cannot produce viable offspring. His paper in the February issue of Ecology shows that when seed predators are abundant, investment in decoy seeds \u2013 or \u201csacrificial siblings\u201d \u2013 can increase a plant\u2019s chances of producing successful progeny.<\/p>\n<div><a href=\"http:\/\/www.esajournals.org\/doi\/abs\/10.1890\/07-1436.1\">Nonviable seed set enhances plant fitness: the sacrificial sibling hypothesis<\/a><\/div>\n<div>Jaboury Ghazoul and Akiko Satake<\/div>\n<p>Ecology 2009 90:2, 369-377<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The success of an animal or plant is determined by how many offspring it produces.
