Biological Phenomena

Fenómenos biológicos 

A highly diverse group of mainly aquatic, autotrophic, photosynthesizing organisms ranging from microscopic single-cell forms to multicellular forms, distinguished from vascular plants by the absence of structures such as true roots, stems, leaves and flowers. (Agrovoc)

Algae

Algas

Algal blooms are caused by abnormal increases in the concentration in the water column of certain microscopic algae and algae-like organisms that can cause changes in the color of the water due to the pigments present in the microorganisms. Some of these organisms produce toxins that can be harmful to man, either directly or through the consumption of contaminated seafood. The term "harmful algal bloom" (HAB) is preferred over "red tide" because the blooms are not always red and are not directly associated with tides, and because the term "red tide" applies to many harmless blooms that discolor the water but may exclude many toxic blooms that do not cause water discoloration.

Las floraciones de algas son causadas por aumentos anormales en la concentraci&oacute;n en la columna de agua de ciertas algas microsc&oacute;picas y organismos similares a las algas que pueden causar cambios en el color del agua debido a los pigmentos presentes en los microorganismos. Algunos de estos organismos producen toxinas que pueden ser da&ntilde;inas para el hombre, ya sea directamente o mediante el consumo de mariscos contaminados. Se prefiere el t&eacute;rmino "floraci&oacute;n de algas nocivas" (HAB) a "marea roja" porque las flores no siempre son rojas y no est&aacute;n directamente asociadas con las mareas, y porque el t&eacute;rmino "marea roja" se aplica a muchas flores inofensivas que decoloran el agua pero puede excluir muchas floraciones t&oacute;xicas que no causan la decoloraci&oacute;n del agua.
