Diatom

shrimp ponds were reported to be affected by algal blooms and the responsible algae were the prasinophyte Nephroselmis sp., Cochlodinium polykrikoides, Prorocentrum rhathymum, P. minimum, and Heterocapsa triquetra (dinoflagellates) and Nitzschia sigma (diatom) (Gárate-Lizárraga et al., 1999; 2004; 2006; Sierra-Beltrán et al., 2005; Gárate- Lizárraga and Muñetón-Gómez, 2008). Severe losses in shrimp farming in Mexico caused by toxic dinoflagellates and cyanobacteria have been reported by Ochoa…

prokaryotes or eukaryotes, meaning species such as bacteria, archae bacteria, mycoplasma and cyanobacteria are included. The protista kingdom consists of aquatic, single celled eukaryotes. These eukaryotes are generally photosynthetic, including diatoms, golden algae, and protozoans. The Mycota kingdom (kingdom fungi) consists of mycelium, with hyphae bodies (long, thread-like structures). These organisms generally include saprophytes/parasites and symbionts. The metaphyta kingdom (kingdom…

The marine world is highly dependent on the activity of microbes in many different ways. Microbes in the ocean come in the form of autotrophs and heterotrophs and come in any of the three domains of Eukaryota, Archaea, and Bacteria. Members of these domains can range from all niches as producers at the bottom of the food change, critical gut microbes and decomposers. Arguably, somewhere these and more duties are most important is around the hydrothermal vents found at the bottom of the ocean.…

Bats Bats, the blind and bloodthirsty monsters that live o ff of the blood of its prey are a very essential part in today's ecological system. Bats are found all around the world and although Hollywood and human folklore have portrayed these furry mammals as bloodthirsty monsters, of the 1200 di ff erent species only three are bloodsucking. Most bats on the other hand focus their diets on insects, fruits, and small animals i.e. frogs and lizards. Insectivores bats, who as the name…

BIOLOGYOF TARO LEAF BLIGHT (Phytophthora colocasiae Racib) - A REVIEW ABSTRACT Taro is a tropical tuber crop highly valued in developing countries. It is mostly susceptible to Phytophthora colocasiae, a leaf blight disease (TLB) causing a 25%-50% loss in yield. The pathogen results not only in reduction in vigor, quality and yield but also constitute a barrier to international exchange of germplasm. The warm, humid days, cool and wet nights of the tropics are ideal for reproduction and…

The Effect of pH Level on the Amount of Brine Shrimp Hatched By: Maggie Lazaroski and Paloma Diaz Period 1, January 8 2014 Introduction Paragraph In this experiment, we will be using brine shrimp to measure the effects of pH on the survival rate of invertebrate creatures. We will use white vinegar and baking soda to alter the level of pH, the white vinegar to make the pH level higher and the baking soda to make the pH lower. We will be feeding the shrimp yeast, which is completely…

cuttlefish, and Crown of Thorns starfish, although of different species, sizes, and niches, all adapt for one of two common goals: to eat or to keep from being eaten. Adaptations include camouflage and poison. Producers like Halophila seagrasses, diatoms, cyanobacteria, mangrove trees, zooxanthellae, sea lettuce, caulerpa, dinoflagellates, coccolithophore, and rhodophyta, whether they are green plants or phytoplankton, all adapt to stay in the reef. Adaptations include roots that anchor the…

replacing bone and mimicking their structure for, various applications. When looking at biological materials, to determine their effectiveness as a scaffold or sufficient structure for various other uses, often they are tested for their resistance to fracture. This is referred to as fracture propagation. Bamboo Bamboo is well known for its sufficient mechanical properties, and great flexibility. It also has great fracture toughness. Bamboo is considered to be a bio composite, meaning it…

Agricultural activities, including commercial farming and livestock production, has always been a priority for food availability. The countries around the world are getting many pressures on food supply as the world's population grow every second. This results in some countries expanding farm yields and some increasing the quality and quantity of crops by using more fertilizers and pesticides. It should be noted that agriculture use a global average of 70% of freshwater resources and the…
