Relationship between algal cover and water chemistry in rockpools Ahmad Mukhris Ahmad Mahadzir ABSTARCT Intertidal rockpool is one of the harshest environment in marine ecosystem. Most of the organisms living in it has to have adaptions to survive in harsh conditions‚ especially algal. A research was done to see if abiotic factors such as temperature‚ dissolved oxygen‚ temperature and pH value could have a significant correlation with total percentage of algal cover. Initial hypothesis was

Tables 1 and 3 shows the measurements of the 10-meter stretch of Bear Creek that includes a pool and a riffle. The first table also shows the recorded time and weather in which our class collected the data during that particular day. The upper‚ middle‚ and lower transects are measured using meters. Each of the transects are first measured by width and then by depth on the: Left edge‚ mid-stream‚ and right edge. Then there is description on the substate and the site on both the upper and middle

Introduction Paragraph The question that’s being investigated is what is the water quality of the U-high creek based on the macroinvertebrates found in the creek. Water quality can be measured in various ways including oxygen levels‚ pH‚ nitrogen and phosphorus levels. Dissolved oxygen is when oxygen molecules mix with water molecules. It is important because water gets into oxygen from the surrounding air.The pH scale is used to measure the relative acidity of solutions and phosphorus is a chemical

COMMISSION Eutrophication and health 40 preface Eutrophication and health Algal blooms‚ “red tides”‚ “green tides”‚ fish kills‚ inedible shellfish‚ blue algae and public health threats. What is the common link ? The answer is‚ EUTROPHICATION: a complex process which occurs both in fresh and marine waters‚ where excessive development of certain types of algae disturbs the aquatic ecosystems and becomes a threat for animal and human health. The primary cause of eutrophication is an excessive

The rise of toxic Microcystis algae blooms in Lake Eerie A combination of climate change and agricultural practices have led to an excess run off of phosphorus in Lake Erie‚ resulting in excess algae blooms spread across the surface of the water. Phosphorus is the key nutrient that dictates algae growth and abundance. Microcystis‚ a species of cyanobacteria characterized by its blue colour continually contaminates the waters‚ and damages marine ecosystems‚ due to its toxicity. Being the smallest

1.2 How have environmental cycles changed? The capacity of ecosystems to provide benefits to humans‚ that is to provide ecosystem services‚ derives from environmental cycles of water‚ nitrogen‚ carbon‚ and phosphorus. These processes have in some cases been significantly modified by human activity. Changes have been more rapid in the second half of the 20th century than at any other time in recorded human history. Water cycle: Water withdrawals from rivers and lakes for irrigation‚ urban uses‚

Expected results in a confirmed case of shigellosis are as follows: Brilliant Green Agar – Isolated Shigella colonies which do not ferment lactose or sucrose and appear red or white in color with no growth to trace growth on the Agar plate will be present. Triple Sugar-Iron Agar – Presence of Shigella will manifest as a red slant with

Nutrient pollution- Fuels the growth of algae blooms that block sunlight from reaching bay grasses and rob the water of oxygen. Sediment pollution- Sediment is soil particle that have entered creeks‚ rivers and lakes. Toxic pollution- In our environment threaten our rivers and lakes‚ our air‚ land‚ and
