Cabulig River is bounded by Upper Jasaan and Bobontugan. The people will cross the river using bangka or bamboo boat. People living there make use of the river as their bathing area and for washing the clothes. The Table 1 shows the phytoplankton species per station in Cabulig River. With a population density of 583 species per millilitres‚ there were twenty (20) phytoplankton species found in Cabulig River. There are seven (7) orders in the class Bascillariophyceae. Three (3) of which belongs order

nutrients leading to algal blooms and anoxic events) is a persistent condition of surface waters and a widespread environmental problem (Carpenter‚ 2005). The main cause is excessive loading into the system of phosphorus and nitrogen‚ resulting in high algal biomass‚ dominance by cyanobacteria‚ and loss of macrophytes (Dixit‚ 2005). When the nutrient concentrations rise to extremely high levels‚ eutrophication occurs. There are two stages‚ which begin with the algal bloom. Algal bloom creates a barrier

growth‚ but no contamination. Furthermore‚ Lyngbya cultured in enriched agar did not grow beyond the area of inoculation. Isolation was also more difficult in agar than in the liquid control medium. INTRODUCTION As early as the 1900s‚ Lyngbya sp. blooms were documented in the areas of Eastern Moreton Bay and Bribie Island in Australia (Abal & Lawn‚ 2004). Lyngbya is a genus which is composed of species which are usually inhabitants of the sea. Numerous species reside in estuarine places and in brackish

fertilizers and pesticides from agriculture that are collected in rivers that flow into the Gulf. Other reasons might be because of all the oil spills we happen to cause in the Gulf 5. Explain how a Harmful Algal Bloom can impact an ecosystem. Its cause would be terrible because the bloom would reach algae or oysters which are eaten by many organisms in the sea causing their death rates to increase and also cause the fish to carry the toxins which are eaten by humans and cause disease. 6.

negative effects can red tide cause for the marine environment? If upwelling aids in phytoplankton growth‚ would less upwelling affect phytoplankton numbers? How? How does a decrease in phytoplankton affect the rest of the food web? Would harmful algal blooms cause erosion? If phytoplankton help reduce carbon dioxide on Earth‚ what would an increase amount of phytoplankton do for carbon dioxide amounts? Marine Iguanas (Lesson 4.07) What do they primarily feed on?

Apparatus: boat Introduction: Lime cay is a small coralline cay that is mostly used by humans for their personal entertainment. By visiting this cay‚ man has had detrimental effects on the environment. In the earlier times‚ man’s impact was not so prevalent‚ however‚ overtime it has increased as agricultural practices and technology has been introduced. The effects can rise

are washing them away without a care of what happens next. In doing so‚ they are eventually ending up back into our oceans and cause these harmful algal blooms‚ known as Red Tide. Most of these algal blooms are toxic‚ causing death to marine life around it‚ making it unsafe to eat‚ and causing pollution in the air we breath. How do these algal bloom begin to form in the first place? In gaining an a better understand we have to remember that aquatic ecosystems

Knowing Exposure Risks Important to Saving Structures from Wildfires Sep. 4‚ 2013 — A recent study of one of California’s most devastating wildland fires by the National Institute of Standards and Technology (NIST) and the U.S. Forest Service (USFS) strongly suggests that measures for reducing structural damage and property loss from wildland urban interface (WUI) fires are most effective when they are based on accurate assessments of exposure risks both for individual structures and the community
