Abstract

ABSTRACT Conceived as a baseline for the management and conservation of the marine protected area of the French Southern Territories (réserve naturelle nationale des Terres australes françaises), the checklist of marine macroalgae of the Kerguelen Islands was updated based on an extensive review of the literature and scientific databases, from the first report of the Ross expedition, in 1840, to the most recent works. This work was also conceived as a starting point for forthcoming investigations using molecular systematics tools and for monitoring the effects of global change on sub-Antarctic marine ecosystems. After a brief history of scientific campaigns, a list of 166 species was established (103 Rhodophyta, 35 Chlorophyta and 28 Ochrophyta [Phaeophyceae]). Molecular systematics studiess have shown the existence of recurrent discrepancies between the established, morphology-based taxonomy and molecular species delimitation, calling for a revision of systematics. Nevertheless, a first analysis of biogeographical affinities of the marine flora of the Kerguelen Islands is carried out and preliminary results are partially congruent with the main regions currently recognized in the Southern Ocean suggesting the importance of long-distance dispersal to explain the observed distribution patterns.

凯尔盖伦群岛的海洋植被:科学运动的历史，植物区系的清查和其生物地理亲缘性的初步分析

作为法国南部领土海洋保护区管理和保护的基线(rserve naturelle des Terres australes franaises)，凯尔格伦群岛海洋大型藻类清单是在广泛审查文献和科学数据库的基础上进行更新的，从1840年罗斯探险队的第一份报告到最近的工作。这项工作也被设想为今后使用分子系统学工具进行调查和监测全球变化对亚南极海洋生态系统的影响的起点。经过简短的科学研究，建立了166种植物的名录(红藻103种，绿藻35种，绿藻28种)。分子系统学研究表明，在已建立的基于形态的分类和分子物种划分之间存在反复的差异，要求对系统学进行修订。尽管如此，对凯尔盖伦群岛海洋植物区系的生物地理亲缘性进行了初步分析，初步结果与目前在南大洋公认的主要区域部分一致，这表明远距离分散对解释观察到的分布模式的重要性。
