simplest form of a trash littered beach that almost any resident of Florida can attest to or it can take the form of something much greater. This greater form of pollution is the massive outbreak of green algae that has occurred in Florida with one of the most recent back in July of this year. The algae outbreak is caused by “fertilizer sewage and manure pollution that the state has failed to properly regulate” as stated by Earthjustice spokeswoman Alisa Coe. This

because both are key elements in growth in lakes. The Virtual lake includes these five simulated species; green algae, cyanobacteria, bosmina, daphnia, and trout. There are two types of phytoplankton in the lake model, green algae and cyanobacteria. Green algae are a very diverse group that are photosynthetic, aquatic, plant like organisms that have a very simple reproductive structure. Green algae growth is a healthy and natural part of a lake’s ecosystem but the addition of nitrogen and phosphorus

The Island Biogeography theory and species richness in different tidal pools on St Lucia coast lines By: Daniela Maia student number: 201406936 Introduction Islands are most commonly known as landmasses that are surrounded by a body of water, in this case the ocean is the body of water. Islands, however, are also isolated areas within another area that bear different species that are rare as well as unique in comparison to the surrounding environment (habitat within a habitat) says

gastropod mollusk, abalones are characterized by one shell.Several abalone species have been identified of present or potential economic value whether for capture fishery, stock enhancement or aquaculture. These include red abalone (Haliotis rufescens), green abalone (Haliotis fulgens), Japanese abalone (Haliotis discus hannai) and Omani abalone (Haliotis mariae). Abalone has a worldwide distribution; with some exceptions, they occur along the coastal waters of every continent. According to FAO statistics

species is native to the coasts of Chile and Peru and is considered among the key benthic herbivores in Chilean coastal waters. It is harvested commercially by fishermen and is considered an ingredient in Chilean cuisine. It is also known as “common green sea urchin” and its local name in Chile is “Erizo rojo” which means “red urchin”. They can grow up to 100 mm in diameter or more. It takes eight years for Chilean sea urchins to reach commercial size. The industrial catches and over-exploitation of

bleaching is when the animals that build the coral shed the algae that give them their color and is necessary for survival. Coral bleaching is suspected to happen by two different ways. The first is due to warmer water. The coral needs to be in certain temperature in order to maintain its life. The second way is due to pollution. This could mean over exposure

Introduction In order for a coral reef to be productive and healthy, the water quality in the ocean should be maintained. Water quality not only affects coral reefs, but the other organisms that live on it and are involved with the natural food chain. Some of the factors that can influence water quality are nutrients, temperature, salinity, dissolved oxygen, turbidity, light, and chlorophyll present. Water is essential to every living organism because it helps with respiration, maintaining body

Effects of Red Tides on Ecosystems Background Info: Harmful algal blooms, or more commonly known as red tides, occur when a dinoflagellate colony grows out of proportion. Dinoflagellates are a type of algae and protist responsible for releasing a chemical that acts as a neurotoxin (called brevetoxins) in many organisms. This results in neurological effects in animals, birds, and other marine life. Red tides are not considered a new phenomenon, as they were first documented in the 1700s in the Gulf

threatened by climate change, pollution, and overfishing. All in which are man made influences that affect the ocean greatly. It is predicted that by the year 2050 90% of the coral reefs on earth will be dead or threatened. Not only that but soil erosion, algae growth from fertilizer runoff, increased UV exposure, and damage from fishing and diving are just adding to the problem. However, the

depths of about 750 meters. They can weigh up to 44 pounds and reach a length of about 25 inches, however they are typically around 2 feet long and weigh 3 pounds. The American lobster’s preferable habitat is on rocky surfaces covered with algae, because algae attract animals that the lobsters prey on. This habitat allows the lobster to hide within the cracks, where it can hide from predators in its environment such as flounder, cod, crabs and eels. They dig burrows under large stones to make usable

There are seven characteristics which make organisms different from non living things. These characteristics include growth, reproduction, irritability, movement, nutrition, excretion and respiration. The starfish is considered to be alive because it portrays the seven characteristics of a living organism. A starfish is considered to be undefined. It is continuously growing and all cells preserve the aptitude to develop into whatever section is considered necessary. several variety of starfish encompass

Hermit crabs are marine crabs of the family Paguridae, the most common being Pagurus bernhardus, and are found off of the coast of Europe and the Americas (“Hermit Crabs”). There are two main families of hermit crabs: marine hermit crabs and land hermit crabs. Marine hermit crabs mostly live underwater in various depths of saltwater, while land hermit crabs mostly live on land, but can also survive under water. Land hermit crabs are found in tropical areas, more specifically those of the Indo-Pacific

The huge numbers of algae can block the pores on sponges, block light penetration through to the zooxanthellae living within the corals, and decrease the its resistance to coral diseases. Pollutions such as sewage outflow, the use of fertilizers from both urban and agricultural

Summary The findings and analysis of this study are very interesting. Along with the vast array of ecological significance of Agumbe, there are many other cultural and spiritual beliefs attached to it. It was found that the importance of Agumbe rainforest has been exemplified due to the presence of King Cobra in this area. People have taken initiative to preserve the rainforest in the name of Nagabana. This part of forests cannot be destroyed under any circumstances as that area is devoted to their

Which Country Has the Most Islands? Estimates show that approximately 700 million people on earth live on islands, most of whom have unique cultures that have significance in their environmental resources. Islands are very popular with people who want to have good and relaxed time because of the experiences they offer by being hotbeds of biodiversity having rare flora and species. Because of their remoteness, islands are good examples of clean environments that support healthy organisms including

Beautiful places in Madagascar Madagascar, one of the most splendid island found off the southeast coast on Africa. The huge island is home to several animal species, such as lemurs. It is also famous for its rainforest, beaches and reefs. One of the most visited attraction is the ‘’Avenue of Baobabs found near Antananarivo, the capital of the island. Madagascar has a variety of things to discover and have unique features that attract tourists all around the world. Palais d’Andafravatra The palais

Sea cucumber Introduction: Sea cucumbers are echinoderm animals that belong to the class Holothuroidea. These marine animals are characterized by their leathery skin and an elongated body. They are more than 1250 classified species of sea cucumber that can be found in oceans throughout the world. Usually sea cucumbers live on the sea floor. All sea cucumbers are ocean dwellers, though some inhabit the shallows intertidal zones while others live in the deep ocean of 5,000 m and more. Most sea

specializes in helping save coral. Corals have very special tolerances to things like temperatures, salinity levels, and pollution, which causes coral stress, or bleaching. When bleaching occurs because of the unsuitable conditions, the corals expel the algae living in them, turns white, and dies, When corals die, thousands of sea creatures living around reefs

Coral reefs. By: Valentina Sarria. Coral reefs are one of the most diverse and complex habitats. They are one of the most interesting and colorful ecosystems found in the marine environment. They are very unique in many different ways and a crucial support for human life. They play also a very important role in the marine life such as giving shelter and food for millions of species including fishes, crabs, or shrimps. They support 33% of marine fish species. They also have specific and certain
