Brown algae

Hawaiian algae published on the UH website, I identified the algae as of the genus Padina, however I am not quite sure which species it is. The most common species of Padina in Hawaii are the P. australis and P. japonica, and is sometimes referred to as "peacock's tail" because of its fan-like shape. Padina is a member of the class phaeophyceae, which is a class of brown algae. The peacock's tail alga is not harmful when eaten, however it can be dangerous when walking across rock, as the algae can get

in facilitating the growth of kelp forests all around the world, (Bolton). Kelp specifically dominates the shallow rocky coasts of the world‘s cold water marine habitats. Although they look as a free-growing plant, they are in fact primarily of brown algae. These structures provide food and shelter to a huge mix of biota, including crabs, sea urchins, mollusks, and other marine organisms (Steneck). The fronds, or large leaves of the kelp are the distinctive feature that can represent where a specific

Modern Uses of Cultivated Algae Algae are a "group of plants" that dominate the aquatic environment (Raymount, 1984). Organisms that make up the algae include representatives from three kingdoms and seven divisions: cyanochloranta and prochorophyta (from Kingdom Monera), pyrrhophyta, chrysophyta, phaeophyta, and rhodophyta (from Kingdom Protista), and chlorophyta (from Kingdom Plantae). All seven divisions are called algae because of a lack of roots, stems, and leaves; and most algal cells are

Photosynthetic pigments Introduction Some animals and most plants use photosynthesis to convert light energy into chemical energy. The energy that is created can be stored and is accessed later on by consumers. The consumers of the organisms break bonds while digesting the plant material and the stored energy is released into their perspective systems. The entire process of photosynthesis can be summarized as carbon dioxide and water reacting with light to create sugar, water and oxygen. Although

The white abalone is an invertebrate in the phylum Mollusca and the class Gastropoda. It is a member of the family Haliotidae and its scientific name is Haliotis sorenseni ("White Abalone - Haliotis sorenseni"). Abalone are large sea snails prized for their beautiful iridescent shells and have been sought out as food and jewelry since pre-colonial times. Though abalone have existed since the Precambrian era, the earliest harvesters of abalone were Native Americans who lived along the intertidal zone

Intense grazing by herbivores can drastically affect the amount of seaweed present. Having secondary metabolites can be used as a defence mechanism. Many different genres of algae were studied, having many different types of chemical compounds found on many different parts of the world. Most studies harvested and purified samples then exposed these samples to different herbivores. The herbivores varied in size from large fish to smaller organisms such as amphipods. Aspects such as survivorship, behaviour

Are you sick of algae in your aquarium? Your saltwater aquarium lighting may be your problem… Algae is inevitable in any saltwater aquarium and will always be present as part of the natural ecosystem, however there are steps you can take as part of your ongoing saltwater aquarium maintenance schedule to decrease the rate and density of growth.There are several types of algae however the most common found in a saltwater aquarium is brown algae otherwise known as golden diatom algae. When I first

Diversity of Marine Algae in the Biosphere 2Ocean Red algae, Rhodophyta, is easily identified in the marine environment because it appears as a red color. There are many different species, originating from many different corners of the Earth. The ocean biome in the Biosphere 2 was constructed using raw seawater off the coast of Southern California, which contained many different unknown species of algae. During the construction of the biome, other known species of algae from various marine

Algae blooms have been an issue in the Chesapeake Bay, especially in the Baltimore Inner Harbor. Algae is a natural and critical part of the ecosystem, however in large doses it is harmful to the plants and organisms within the ecosystem. Algae blooms can block out sunlight and kill other plants in the water. Algae depends on various factors such as water, nutrients and carbon dioxide to grow. Eutrophication of the Inner Harbor has lead to algae blooms that have caused large fish kills in the past

mainly found in tropical and subtropical waters. Green turtles are generally found in fairly shallow waters (except when migrating) inside reefs, bays, and inlets. The turtles are attracted to lagoons and shoals with an abundance of marine grass and algae. Open beaches with a sloping platform and minimal disturbance are required for nesting. The green sea turtle grows to a maximum size of about 4 feet and a weight of 440 pounds. It has a heart-shaped shell, small
