Harmful Algae :: Geology

AbstractThe purpose of this term paper is to provide discipline about the different kinds of algal tiptops and their effect on our environment and ourselves. on that point are still a lot of things that are non know about the algal bloom phenomenon, and many different hypotheses have been presented to justify these. Throughout the course of this paper those hypotheses will be presented and discussed, allowing the reader to issue forth their own opinion about the origin of algal blooms and what will reach in the future. table of contents Table of ContentsI.

Resources I. Harmful Algae All algal species are not mischievous. single a few out of the thousands of species are associated with the phenomenon known as an algal bloom. These alga fall into two categories. T he first category of harmful algae produces toxins that are released when ingested by animals or humans. The dinoflagellate Alexandrium tamarense (left) and the diatom Pseudo-nitzschia australis (right) are examples of toxin producing alga. The other category of harmful algae kill without toxins. These are equipped with structures such as spines and ser valuated edges that allow them to lodge in fish gill tissues. When this occurs it causes irritation which leads to overproduction of mucus which eventually leads to death. This Chaetoceros species (above) is an example of an algae that kills by using change serrated structures. back to table of contents II. What Are Algal Blooms and Red Tides?Algal blooms are when algae grows at a fast rate and accumulate near the surface, hence the term algal bloom. The term Red Tide is a misnomer because it has nothing to do with the tides. It refers to a unique(predicate) type of algal bloom that occurs when certain species of phytoplan kton that contain red pigments bloom causing the water to look red. Red Tides are usually not harmful. The California Noctiluca Bloom is an example of a Red Tide back to table of contents III. Why Do algal blooms run?Scientists arent exactly sure of how or why algal blooms get started. unrivaled theory is that when temperature, salinity, and nutrients reach certain levels there is a massive development in the amount of algae.
