Sargassum that also can mean all seaweed species washed up on shore. "Sargassum" species are found throughout tropical areas of the world and are often the most obvious macrophyte in near-shore areas where "Sargassum" beds often occur near coral reefs. The plants grow subtidally and attach to coral, rocks, or shells in moderately exposed or sheltered rocky or pebble areas. These tropical populations often undergo seasonal cycles of growth and decay in concert with seasonal changes in sea temperature. In tropical "Sargassum" species that are often preferentially consumed by herbivorous fishes and echinoids, a relatively low level of phenolics and tannins
Plant breeding Plant breeding Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. It has been used to improve the quality of nutrition in products for humans and animals. Plant breeding can be accomplished through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to methods that make use of knowledge of genetics and chromosomes, to more complex molecular techniques (see cultigen and cultivar). Genes in a plant are what determine what type of qualitative or quantitative traits it will have. Plant breeders strive to create a specific outcome of
