摘要

The role of toxic cyanobacteria in wildlife conservation is poorly known. However, toxic cyanobacteria blooms could have a very important effect on wildlife. In particular, mass mortalities of waterbirds are receiving improved attention in recent years because of their increased occurrence. Cyanobacteria toxicosis by microcystins (potent hepatotoxic cyclic peptides) should be taken in account as a significant cause of such mortalities in eutrophic inland water systems. A suitable procedure to diagnose waterbird mortalities due to toxin-producing cyanobacteria (microcystins) should be based on five sequential steps: (i) macroscopic in situ evaluation searching evidences of cyanobacteria blooms; (ii) identification of toxic cyanobacteria species; (iii) analysis of water samples searching for microcystin detection; (iv) epidemiology and clinical sings; and (v) post-mortem examination of waterbirds to verify that microcystins reach to digestive system of birds. This procedure was employed to analyze recent mortalities of Waterbirds in Donana National Park (S Spain), revealing that toxicosis by microcystins was the main cause of the worst mass mortality.
