Abstract

The present study focused on the dynamics of the phenology and life cycle of the Phaeophyceae invader Sargassum muticum at three sites on the Atlantic coast of Morocco over a period of two years (2013 and 2014). The results showed that S. muticum has two distinct growth phases; one with slower growth in winter followed by one with faster growth in spring-early summer, when the species exhibited high elongation and branching activities with thalli length ranging from 1 to more than 5 m depending on the study site. The site S1, with a rocky substratum covered by submerged sands, promotes thalli elongation, with maximum lengths of 643.33 11.10 cm recorded in July. At the rocky sites (S2 and S3), the maximum length of the seaweed depends on the pools’ depth. Although the elongation of thalli is enhanced by the water body depth, the settlements’ density (5-48 ind. m–2) seems to be mainly related to the nature of the substrate. The maturity index progressively increases from spring to early summer, when it reaches the highest values. S. muticum seems to be more abundant and more easily acclimated in shallow rockpools (sufficiently lighted and semi-exposed to wave action at the mid and lower tidal levels) than in protected sandy bottom sites with low hydrodynamic forces.

摩洛哥大西洋沿岸外来马尾藻物候的时空格局
本研究在摩洛哥大西洋海岸的三个地点(2013年和2014年)对褐藻科入侵动物多发马尾藻的酚学和生命周期进行了为期两年的动态研究。结果表明,多菌有两个不同的生长阶段;一种在冬季生长较慢,另一种在春季和初夏生长较快,此时该物种表现出较高的伸长和分枝活性,铊长度从1米到5米以上,具体取决于研究地点。场地S1的岩石底层被淹没的沙子覆盖,促进了铊的伸长,最大长度为643.33 7月记录为11.10厘米。在岩石场地(S2和S3),海藻的最大长度取决于水池的深度。尽管水体深度提高了铊的伸长率,但沉降物的密度(5-48 ind.m–2)似乎主要与基质的性质有关。成熟度指数从春季到初夏逐渐增加,达到最高值。与低水动力的受保护沙底场地相比,在浅水岩石池(在中、下潮位有足够的光照和半暴露于波浪作用)中,S.muticum似乎更丰富,也更容易适应。

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.
