A freshwater scientist assists in solving the issues in freshwater ecosystems. They analyze environmental factors and genetic issues and also analyze recorded data such as migration patterns and toxin levels. Dr. Rey Donne S. Papa is a Limnologist. The field of the study is called limnology, which is the study of freshwater and ecosystem. His research focuses on the Ecology and systematics of freshwater zooplankton and limnology, including studies on invasive copepods, long-term limnological research, palaeolimnology, freshwater biodiversity and aquaculture impacts.

Freshwater ecosystems are a subset of Earth's aquatic ecosystems. It is a unique and important component of global biodiversity, playing a fundamental role in support of the environment, society and the economy. Ecosystems like wetlands, rivers, aquifers, and lakes are indispensable for life on our planet and are vital for directly ensuring a range of benefits and services such as drinking water, water for food and energy, habitats for aquatic life forms, and natural solutions for water purification and climate resilience, among many others.

Freshwater ecosystems comprise of 0.8% of the earth’s surface but contain 6% of all known species. Managed well freshwater ecosystems also directly …show more content…

Although these conditions are increasingly under threat. In addition to the growing demand that freshwater supplies face for purposes like agriculture, energy, and human settlements, the effects of climate change are exacerbating changes to the hydrological cycle. Climatic changes lead to permanent shifts in freshwater conditions, depleting biodiversity and impacting the proper functioning of freshwater ecosystems, as well as manifesting themselves in more frequent and severe extreme events such as drought and

On the trip with SWEEP the health of the Susquehanna River was studied. In order to do that, chemical test, biological tests, and physical observations were made. Chemical testing showed the more scientific side of water quality, such as the amount of nitrates, phosphates, the pH values, temperature, dissolved oxygen, and turbidity. Searching for macroinvertebrates was the biological testing. Certain macroinvertebrates and the quantity found determines how healthy the stream is.

Eversince the invasion of Zebra mussels in 1988 the ecosystem of The Great Lakes suffered negative impacts from decrease of plankton to spending big numbers every year to try to remove them from the ecosystem. But little do people know they also help brought Lake erie (one of the 5 great lakes) back to life, during the 1970s Lake Erie was declared dead since massive amounts of pollution were dumped into the Lake from agriculture industry. The pollution caused the Lake to have less oxygen which caused some parts of the lakes to be a dead zone. Overall this can be concluded to have negative impact to the ecosystem of the Great Lakes, but there are some positive impacts too. The primary objective should be to remove the Zebra mussels from the great lakes even though the had positive impacts, the zebra mussels don’t belong in this ecosystem.

The Cullowhee Creek is a small source of water that runs through Western Carolina University. The creek begins further up the mountain, then runs into the Tuckasegee River, which then flows into the Tennessee river, then the Mississippi, and finally, into the Gulf of Mexico. In this activity, we monitored the creek to determine its health. In the Riparian Inventory activity, we rated various aspects of the creek.

The first figure helped understand the location of the different tributaries in the upper Kiamichi River being used in the experiment. The first table helped highlight the point that the known range of O. saxatilis was shown to have increased and that the sympatric species P. tenius inhabits the same streams as O. saxatalis compared to the other sympatric species. Table 2 helped demonstrate that depth and flow velocity differed between riffles and pools especially between the dry and wet periods. This showed that the difference in water levels between riffles and pools could affect the habitat that the crayfish is living in and their preference for a certain environment. The other abiotic factors did not vary dramatically, which showed that they do not affect crayfish distribution.

72580 Rodriguez Silva The Top-down Effects of Brine Shrimp on Algae INTRODUCTION An ecosystem is a delicate structure moderated by the network of interactions between all of the organisms that inhabit it. These organisms can be arranged into trophic levels, forming a chain or pyramid in which energy flows from one level to another.

The marshland itself harbors a wide array of ecosystem services. The water in the marshland at the Shawsheen River site has a pH of 5.5. It is slow moving with a speed of 36.88 meters/second. Where the water is moving faster there is more oxygen; whereas, where the water is moving slower, there is more Carbon Dioxide. This is a provisioning ecosystem because when the dam is removed, there will be less carbon dioxide because of the increased water velocity.

In major league baseball the late 80’s through early 2000’s can be described as the “Steroid Era”, in which many athletes were caught using performance-enhancing drugs that resulted in higher offensive performance, especially the number of home runs per season. As professional baseball is getting more and more competitive many athletes look to unethical ways to gain physical advantages over other players by taking steroids. For instance, Mark Mcgwire admitted to using steroids and had a phenomenal increase in offensive statistics in 1998 compared to other seasons. In his season of 1998 he broke the baseball single season home run record of 70 home runs, which was far more home runs he had hit compared to previous seasons when he wasn’t

People may know about climate change and the drastic changes it is having on the environment, but what they may not be aware of is that another degree increase in the world’s average temperature will cause even bigger problems for people all over. Climate change is long term shifts in temperature and patterns in the weather. Greenhouse gasses, gasses that trap heat in the atmosphere causing it to warm up are at an all-time high due to humans and the amount of fossil fuels we use. The most crucial result of climate change is global health, but animal endangerment and the rise in sea levels are also very important effects.

“As the population rises, the world 's water usage will rise. Many areas of the world already suffer from a lack of fresh water,” (Population Control 3). If the world runs out of freshwater, humanity will plunge into chaos. Humanity needs water to survive, and that is a fact. Relationships between countries will be broken apart over disputes for water.

Certain species have a huge impact to an ecosystem, but even the smallest fish could have the biggest impact. Overfishing occurs when more fish are caught than the population can replace through natural reproduction (overfishing). The results not only affect the balance of life in the oceans, but could also affect the coastal areas that depend on fish for their way of life. For centuries, our seas and oceans seem to be considered a limitless food supply. But that is not the case, increasing fishing efforts over the last fifty years as well as unjustifiable fishing practices are pushing many fish stocks to the point of extinction.

The Biotope Aquarium Explained In a biotope aquarium, the aquarist attempt to simulate a natural habitat, assembling fish species, plants, water chemistry and decorations found in that specific ecosystem. A “true” biotope should be a mirror of a natural habitat. There are many good reasons for setting up an aquarium that simulates a natural habitat. Those of us who have done everything, bred everything and kept most fish might simply want a new challenge.
