Abstract

As part of a continuing toxic microalgae monitoring program, 22 phytoplankton samples were collected from July to November 2010 at several sampling stations along the southern coast of the Baja California Peninsula. For the first time, the toxic dinoflagellate Pyrodinium bahamense var. compressum was found along the southeastern and southwestern coasts of the peninsula. P. bahamense var. bahamense was first observed off San José del Cabo, which is an extension of the range of this variety. Both varieties occur as solitary cells. P. bahamense var. compressum occurred at temperatures ranging between 24.5°C and 31°C, whereas var. P.bahamense occurred at 28.5°C to 29°C, indicating its tropical and subtropical nature. Occurrence of P. bahamense var. compressum along this coastline may be related to El Niño 2009-2010.

摘要

作为一项持续的有毒微藻监测计划的一部分，2010 年 7 月至 11 月期间，在巴哈加利福尼亚半岛南部沿海的多个采样点采集了 22 个浮游植物样本。首次在半岛的东南和西南沿海发现有毒甲藻 Pyrodinium bahamense var. compressum。P. bahamense var. bahamense 首次在圣何塞德尔卡沃（San José del Cabo）观测到，这是该品种分布范围的延伸。这两种变种都以单个细胞的形式出现。P. bahamense var. compressum 的温度范围在 24.5°C 到 31°C 之间，而 var. P.bahamense 的温度范围在 28.5°C 到 29°C，表明其具有热带和亚热带性质。这种沿该海岸线出现的 P. bahamense var. compressum 可能与 2009-2010 年的厄尔尼诺现象有关。
