We report on the relationships between some conspicuous Mediterranean photophilous sponge species and Caulerpa cylindracea, a non-indigenous species. A diversification of defence strategies and behaviour is highlighted in target species belonging to different orders of Demospongiae from a western Mediterranean Marine Protected Area (NW Sardinian Sea). Caulerpa cylindracea displays a strongly invasive behaviour during body colonization of the Irciniidae Sarcotragus spinosulus and Ircinia retidermata (order Dictyoceratida). These sponges possess pre-adaptive defensive morpho-functional and physiological traits enabling them to partly withstand algal invasion. Also Aplysina aerophoba (order Verongiida) seems to be able to control colonization. Successful anti-Caulerpa strategies characterize the rarely affected Crambe crambe (order Poecilosclerida). Species-specific competitive strategies are displayed at different levels of body architecture, behaviour and physiology by native sponge species. The invasion patterns on sponges, the invasion dynamics in 2016–2017 and topographic distribution of C. cylindracea on S. spinosulus confirm this algal species as a threat, with potential long-term effects on sponge assemblages. Data suggest other kinds of poorly investigated synergic stressors affecting these habitat-forming species. Defence strategies of sponge species take the form of: (1) passive deterrence by morpho-functional pre-adaptive traits as growth form, biomass amount, surface traits, and microhabitat within the sponges' aquiferous system; (2) active physiological defence, whereby the morphology/anatomy of the sponge body is adapted to control invaders, by body remodelling and regenerative processes within the aquiferous system and at the sponge surface; (3) presumed active chemical defence by exudation processes of bioactive compounds.

地中海西部海洋保护区的入侵绿藻:嗜光海绵与 Caulerpa cylindracea 的相互作用

我们报告了一些显着的地中海嗜光海绵物种和柱花草,一个非本土物种。在地中海西部海洋保护区(撒丁岛西北部)属于不同目海绵纲的目标物种中突出了防御策略和行为的多样化。柱花草在 Irciniidae 的身体定植过程中表现出强烈的侵入性行为棘蛉鸢尾(网柄藻纲)。这些海绵具有预先适应的防御形态功能和生理特性,使它们能够部分抵御藻类入侵。还海兔(命令 Verongiida)似乎能够控制殖民化。成功的反考勒巴策略的特点是很少受到影响蟹肉蟹(Poecilosclerida 目)。本地海绵物种在不同层次的身体结构、行为和生理学上展示了特定于物种的竞争策略。海绵的入侵模式、2016-2017年入侵动态和地形分布C. cylindraceaS. spinosulus确认这种藻类物种是一种威胁,对海绵组合具有潜在的长期影响。数据表明,其他类型的研究不足的协同压力源会影响这些栖息地形成物种。海绵物种的防御策略采取以下形式:(1)通过形态功能前适应性状(如海绵含水系统内的生长形式、生物量、表面性状和微生境)进行被动威慑;(2) 主动生理防御,海绵体的形态/解剖结构通过含水系统内和海绵表面的身体重塑和再生过程适应控制入侵者;(3) 假定通过生物活性化合物的渗出过程进行主动化学防御。
