As for many other Azorean Islands, the macroalgal flora of Terceira (belonging to the central group of the archipelago) is poorly known, the published information reflecting occasional collections of sporadic visitors to the island. In order to overcome this and contribute to improve the knowledge of Azorean macroalgal flora at both local and regional scales, a thorough investigation was conducted. Both collections and presence data recordings were undertaken at the littoral and sublittoral levels down to approximately 40 m around the island, covering a total area of approximately 49 km. This paper lists the taxonomic records and provides information on each species' ecology and occurrence on the Island's littoral.
A total of 418 specimens (including taxa identified only to genus level) belonging to 147 taxa of macroalgae, comprising 95 Rhodophyta, 33 Chlorophyta and 19 Ochrophyta (Phaeophyceae) are registered. Of these, 113 were identified to species level (73 Rhodophyta, 24 Chlorophyta and 16 Ochrophyta), encompassing 35 new records for the Island (27 Rhodophyta, 6 Chlorophyta and 2 Ochrophyta). Most species are native, including the Macaronesian endemisms O.C.Schmidt, (Seoane-Camba) S.M.Boo & J.M.Rico and P.Crouan & H.Crouan ex Karsakoff. Eight species are introduced and 15 have uncertain origin.
与许多其他亚速尔群岛一样，特塞拉岛（属于该群岛的中部岛屿群）的大型海藻区系鲜为人知，已发表的信息反映的是偶尔到访该岛的人进行的零星采集。为了克服这一情况，并有助于在地方和区域尺度上增进对亚速尔群岛大型海藻区系的了解，我们进行了一次全面调查。在该岛周围沿海和亚沿海区域直至约40米深处进行了采集和现存数据记录，覆盖总面积约49平方千米。本文列出了分类记录，并提供了关于每个物种在该岛沿海生态和分布情况的信息。
共记录了418个标本（包括仅鉴定到属级别的分类单元），属于147个大型海藻分类单元，其中包括95种红藻、33种绿藻和19种褐藻（褐藻纲）。其中，113个被鉴定到种级（73种红藻、24种绿藻和16种褐藻），包括该岛的35个新记录（27种红藻、6种绿藻和2种褐藻）。大多数物种是本地物种，包括马卡罗尼西亚特有种O.C.施密特、（塞奥内-坎巴）S.M.布和J.M.里科以及P.克劳安和H.克劳安（前卡尔萨科夫）。8个物种是外来引入的，15个物种的起源不确定。
