摘要
Some species of the dinoflagellate genus Alexandrium (Halim) Balech produce potent neurotoxins called saxitoxins (STXs), which can be accumulated in several invertebrates whose ingestion can cause the human intoxication named paralytic shellfish poisoning (PSP). Many of these STXs are transferred through the food chain and thus can also affect a variety of wildlife. The species A. tamarense/catenella were mainly responsible for PSP in Southwestern Atlantic. However, unexpected patterns of diversity in genetic, reproductive compatibility, toxicity, and physiological response were found in several studies. The present review seeks to provide a broad overview of the species A. tamarense/catenella distribution, their toxicity and toxin composition in clonal isolates, and natural populations, using historical plankton, cyst, and toxin records. Also, the metabolic changes that occur in the toxic composition of primary and secondary consumers and the impact produced by their transference through the food chain are evaluated.

一些种类的甲藻（Alexandrium（Halim）Balech）产生强效的神经毒素，称为蛤蚌毒素（STXs），它可以在几种无脊椎动物中积累，其摄入可引起人类中毒，称为麻痹性贝类中毒（PSP）。许多这些STX通过食物链转移，因此也可以影响各种野生动物。 A. tamarense / catenella物种主要负责西南大西洋的PSP。然而，在一些研究中发现了遗传，生殖相容性，毒性和生理反应的意外多样性模式。本综述旨在利用历史浮游生物，囊肿和毒素记录，广泛概述物种A. tamarense / catenella分布，它们在克隆分离物和自然种群中的毒性和毒素组成。此外，评估了一级和二级消费者的有毒成分中发生的代谢变化以及它们通过食物链转移所产生的影响。
