Abstract

ABSTRAKSpesies Caulerpa yang tumbuh di perairan dangkal sampai dilaut dalam dianggap sebagai gangguan ekonomi dan penting. Meskipun invasif di daerah beriklim sedang, spesies Caulerpa terutama C. racemosa dan C. lentillifera (lato) dipanen dan dikonsumsi sebagai makanan, terutama di Filipina. Komunitas Caulerpa di Solong-on, Siquijor adalah salah satu sumber untuk ekspor ke kota tetangga. Penelitian ini bertujuan untuk menentukan stok tegakan biomassa saat ini, prosentase dan keragaman Caulerpa di Solong-on, serta untuk menentukan parameter lingkungan yang dapat mempengaruhi kelimpahan dan keragamannya. Hasil penelitian menunjukkan total delapan spesies Caulerpa diidentifikasi di komunitas Caulerpa dangkal di Solong-on, Siquijor.

菲律宾SIQUIJOR岛SOLONG-ON地区丛生叶藻(绿藻)的立木生物量和多样性

在浅水区到深海中生长的考尔帕菌被认为是一种经济和重要的障碍。虽然Caulerpa物种在温带受到入侵，但它们主要是C. racemosa和C. lentillifera (lato)作为食物收获和食用，尤其是在菲律宾。Siquijor的Caulerpa社区是向邻近城市出口的来源之一。本研究旨在确定当前生物质量的库存、衍生物多样性和Caulerpa的多样性，并确定影响其丰富性和多样性的环境参数。研究结果显示，在Siquijor的Caulerpa浅滩社区中，共有8种Caulerpa。生物质有最高的股票获得的平均生物量的C . cupressoides 26.16±2,44 (SE) g - m-2干重,而C . microphysa有站最少的股票平均生物量9,16±ketebalan 0,26 g - m-2干重。一般来说,股票总生物量站采样期间获得的所有物种是132.57±2.06 g - m-2干重。shannon wiener (H’)的多样性指数从17到2不等，显示了Caulerpa的一个相对多样化的社区。icca规范通信(CCA)分析表明，温度和基质类型是Caulerpa的主要生物质量驱动因素。关键字:生物群落、珊瑚、图图潘、宏藻、从低到深处生长的石化化学物质参数都被认为是经济学家的判断和重要性的。虽然在临时地区有侵入性，Caulerpa物种主要是C. racemosa和C. lentillifera (lato)是收获和消费美国食物，特别是在菲律宾。这样的社区，Siquijor是向邻近市政的资源之一。这项研究旨在确定现在的生物质量、单一的封面和多样性，并有助于确定可能影响其影响的环境参数。结果显示，Caulerpa的8个物种被认为是一个坐落在Siquijor中较低的Caulerpa社区。最高站证券生物质能是获得由C和卑鄙的生物质能cupressoides 26。16±2 . 44 (SE) g干wt m-2, whereas C . microphysa已至少站证券生物质能with an平均均值》9 . 16±0。26干wt m-2 g。将军,《完全站在证券为所有物种生物质能获得19期抽样是132。06 g干wt m-2 57±2。shan非香肠多样性指数从1。7到2暗示着一个真正的多元化社区。坦率地说，他的虚张声势策略的主要驱动因素是珊瑚分析。生物质，考尔帕，封面，机械，物理化学parameters
