Influence of Founder Population Size, Propagule Stages, and Life History on the Survival of Reintroduced Plant Populations

摘要: The reintroduction of rare and endangered species is now widely practiced as a conservation tool to reestablish within their historic range (Guerrant Kaye 2007; Seddon et al. Menges 2008). fundamental goal plant create self-sustaining population with evolutionary potential that can resist ecological perturbations (Maunder 1992; Guerrant 1996a). Reintroduction practitioners face many challenges complex choices, which have been formulated into generic guidelines for reintroducing (Akeroyd Wyse-Jackson 1995; Falk 1996; After choosing sites based on biological, logistical, historical attributes (Fiedler Laven Maschinski [chap. 7], this volume), must decide how individuals introduce, propagule stage what follow-up management treatments aftercare are necessary ensure survives reaches critical demographic benchmarks, including sexual reproduction recruitment the next generation (Pavlik To complicate matters, balance tradeoffs between availability propagules, often limited plants, dynamic theory, predicts initial size composition founding important determinants in survival reintroduced populations 1996a; Kirchner 2006; Armstrong 2007).
