采用多模型模拟的方法，对杉叶蕨藻的生防潜力进行了评价。Agardh由Ascoglossa Elysia subornata（Verrill，1901）在地中海。为此，确定了被认为是关键因素的生物学和生态学参数，以呈现与E. subornata向C. taxifolia和向地中海条件。为此，生长、生存、繁殖、取食C. taxifolia和E.研究了亚羽藻。模拟，考虑到空间效应，给出了令人鼓舞的结果，并表明，在大型围隔生态系统中的额外的实验，可以从事提高实际知识的Elysia行为，对C。模拟结果表明，无论是使用一些成年或混合的成年和幼年蛞蝓，对蕨藻的影响最大。在任何情况下，更好的结果是通过在孤立的点，而不是在集群（具有恒定的表面）的蛞蝓散射。最后，选择一个合适的日期分散增加了弱消费的蕨藻幼蛞蝓分散造成的。(C)2000 Elsevier Science B.V.保留所有权利。
A multi-modelling simulation was performed to assess the potentialities of a biocontrol of the alga Caulerpa taxifolia (Valhl) C. Agardh by the Ascoglossa Elysia subornata (Verrill, 1901) in the Mediterranean Sea. With this aim in view, the biological and ecological parameters considered as key factors were identified in order to present a state of the art on biological and ecological parameters related to the behaviour of E. subornata toward C. taxifolia and toward the Mediterranean conditions. To this end, growth, survival, reproduction, feeding on C. taxifolia and foraging of E. subornata are studied. Simulations, taking into account spatial effects, give encouraging results and show that additional experiments in large mesocosm may be engaged to improve the actual knowledge of Elysia behaviour, the impact on C. taxifolia, the trophic relationships, etc. The results of simulations demonstrate that the greatest impacts on Caulerpa are obtained using either some adults or mixing adults and juvenile slugs. In any case, better results are obtained by a scattering of slugs on isolated spots rather than on clusters (with constant surfaces). Lastly, the choice of a suitable date for scattering increases the weak consumption of Caulerpa resulting from the scattering of juvenile slugs. (C) 2000 Elsevier Science B.V. All rights reserved.
