Abstract
The arrival of non-indigenous species into new areas is one of the main processes altering the oceans globally. Macrorhynchia philippina is a large-sized colonial hydrozoan of an invasive nature. To obtain a deeper understanding of the process of colonization of new areas, it is essential to describe the ecological pattern through scales of temporal and spatial variation. In this study, we describe the colonization by M. Philippina of an oceanic island (Gran Canaria Island, Canary Islands, eastern Atlantic). We describe the abundance and size structure patterns of M. Philippina in three nearshore habitats, rocky reefs, seagrass meadows and rhodolith seabeds, at times before (2014), during (2016) and after (2017) the demographic explosion of this species. On rocky reefs and rhodolith seabeds, the abundance of colonies increased dramatically in 2017 relative to 2014, e.g. from 0 to 138 colonies/100 m 2 . On seagrass meadows, however, the colonies were smaller. In summary, M. Philippina shows an ecological plasticity to rapidly colonize different types of nearshore habitats, but with varying success.
非本土物种进入新区域是改变全球海洋的主要过程之一。菲律宾巨钩虫是一种入侵性的大型殖民地水生动物。为了更深入地了解新地区的殖民化过程,有必要通过时间和空间变化的尺度来描述生态模式。在这项研究中,我们描述了M.Philippina对一个海洋岛屿(大加那利岛、加那利群岛、东大西洋)的殖民化。我们描述了菲律宾M.Philippina在三个近海栖息地,即岩礁、海草草甸和红石海床中的丰度和大小结构模式,在该物种人口爆炸之前(2014年)、期间(2016年)和之后(2017年)。与2014年相比,2017年,岩礁和红岩海床上的菌落数量急剧增加,例如从0个菌落/100 m 2增加到138个菌落。然而,在海草草地上,群落较小。总之,M.Philippina表现出了生态可塑性,可以快速地在不同类型的近岸栖息地定居,但取得了不同的成功。
期刊介绍:
Scientia Marina is the successor to Investigación Pesquera, a journal of marine sciences published since 1955 by the Institut de Ciències del Mar de Barcelona (CSIC). Scientia Marina is included in the Science Citation Index since 1998 and publishes original papers, reviews and comments concerning research in the following fields: Marine Biology and Ecology, Fisheries and Fisheries Ecology, Systematics, Faunistics and Marine Biogeography, Physical Oceanography, Chemical Oceanography, and Marine Geology. Emphasis is placed on articles of an interdisciplinary nature and of general interest.
