Freshwater Mussels Mussels are a species of marine life that inhabits many of the bodies of water in the United States. They serve as an important aspect of the ecological system of the water in which they occupy. However, the number of mussels have been declining such that many are now considered as endangered species. There are a few reasons for the decline in population, including domination by a single species of mussels called the zebra mussel. Conservation has begun on mussels because of
Investigating the Effects of An Abiotic Factor on the Frequency and Distribution of a Freshwater Invertebrate (i) Planning ------------ Introduction ============ Before a complex biological study can be planned and formulated, the terminology in the title above must be clarified. The investigation requires a sound knowledge of ecology, which essentially is the study of organisms, whether they be animals or insects, and their relationship with the environment in which they live
Comparative Essay of Freshwater and Saltwater Fishing My friend had invited me along with him and his family to the ocean. It was vacation for the family, but for him and me it was the beginning of a week of serious business. We had an obsessive hobby to pursue. As avid and long-term freshwater fisherman, we were thrilled by the thought of catching those large and exotic saltwater fish we had seen on television a billion times before. Yet little did we expect there to be such vast differences
or biomes include freshwater, desert, deciduous forest, and the tundra. Freshwater biomes include lakes, ponds, rivers, and streams. Sometimes, ditches and puddles can even be considered freshwater biomes because they help some sort of life to survive. For example, Lake Baikal, located in Central Asia, is the biggest lake on Earth, considered a freshwater biome. Also, the Nile and Amazon rivers are popular freshwater biomes. However, only 3% of the water on Earth is freshwater, where 2% is found
Freshwater is defined as having a low salt concentration — usually less than 1%. There are different types of freshwater regions: • Ponds and lakes • Streams and rivers • Wetlands Streams and rivers ( Floating ecosystem) These are flowing water bodies moving in one direction. Streams and rivers can be found everywhere — their origin may be springs, snowmelt or even lakes, and then travel all the way to mouth, usually another water channel or the ocean. The characteristics of river or stream changes
for us to drink, bathe, cook, wash dishes, to manufacture, and so on. Even the human body is composed of 65% water. Almost everything we do involves the use of water, and yet, only 3% of the earth’s water is fresh water; and only one third of the freshwater is readily available for use. This small fraction supports all life on land. We rely on clean water to survive, but patterns of climate and human activity are threatening our clean resources of water. We are using water at a rate faster than it
A water footprint measures the total water used to produce goods and services that an individual, business, and or a nation uses. In the article "The Freshwater Crisis" National Geographic commented on how insufficient water users humans were and even gave an example of how. The organization said "humans have proved to be inefficient water users. The average hamburger takes 2,400 liters, or 630 gallons
cannot really consider either ethics or sustainability without considering the other • Resources are limited and demand is growing • Challenges in the sustainable use of water and sanitation lies in the inequality in the geographical distribution of freshwater resources. • Given this cannot be helped, it is up to use to ensure we use these resources in a way to promote equality? 2.

either create or expand cracks in the shale. One of the main concerns is the large amount of fresh water used and lost in todays fracturing techniques.

covered by water, most of it is saltwater; freshwater is limited and is not always in the right place, at the right time, or of the right quality. Water, on Earth, exists in several states: water vapor and clouds in the sky, seawater in the oceans, icebergs in the polar oceans, glaciers in the mountains, fresh water lakes, rivers, and fresh and saline water in aquifers. There are significant continental and country differences in the availability of freshwater. Over the last 25 years, these differences
that with global rising, temperatures will continue to get hotter, Svalbard is likely to suffer exactly the opposite fate. Initially, it will become warmer, but this heat will gradually melt the many ice caps and glaciers found around Svalbard. The freshwater released from these huge sources would slowly change the mindscape immediately around it, with the effects it has on the environment spreading out to affect more and more areas. Firstly, the landscape around would be dramatically
Based on the impacts on a coastal location near point Barrow, Alaska which impacts to the ecological, heath, fresh water and societal life. Increasing temperatures in the next 25 years sea thawing permafrost coastal erosion flooding other climate change. Scientist predict that over the next century the temperature increase will be twice as much over the long term norm as it is now. Statewide average annual temperatures could rise from current levels by as 5 to 13 degrees, an average winter temperature
seventy-five3. Freshwater, drinkable water, is the most critical natural resource to humans. As time goes by, the world’s population expands more rapidly, but there is no more freshwater on the Earth than there was two thousand years ago, when the population was three percent of its current size4. Overpopulation has also increased industrial development, which contributes to massive urbanization and rising of living standards5. The increase in industry shrinks the amount of freshwater available because

reach sexual maturity, they return to the freshwater stream of their origin to lay their eggs. Pacific salmon make the round trip only once, but some Atlantic salmon may repeat the cycle several times. Migration between fresh and salt water occurs during every season of the year, depending on latitude and genetic characteristics of the fish. Groups of fish that migrate together are called runs or stocks. Salmon spawn in virtually all types of freshwater habitat, from intertidal areas to high mountain
The Dams: There are nine dams in and directly leading to New York State’s Letchworth State Park. These dams have been built for a variety of reasons and affect nearly 400 miles of freshwater rivers in the Genesee River Basin of Western New York (Fish, n.d.). The Elitsac Manufacturing Company Dam affects 14.08 miles of Wolf Creek (Fish, n.d.). The original purpose of this dam is not documented within the state’s dam inventory, and it is also no longer in service (Dam, n.d.). Another dam on Wolf
and graceful movement of the fish to the frantic feeding frenzy, an aquarium is different each time it is viewed. Although a freshwater tank can be full or color, it does not come close to the fiery colors that are present in a marine aquarium. Unfortunately, all the color and life that a marine aquarium holds is much more fragile and not as easy to keep as a freshwater tank. Therefore, the marine aquarium requires a plethora of devices working together and at optimum levels to maintain a successful
Oceanography Salt Marshes Salt marshes are coastal wetlands rich in marine life, which are covered by water at least once per month. They are found in the intertidal zones along low-energy coastlines, forming along the margins of estuaries, where freshwater from the land mixes with seawater. These marshes can be found near the Great South Bay and the Long Island Sound. The entire south shore of Long Island is considered to be a salt marsh important to the health of the marine life. Beginning in Jamaica
panoramic sceneries of protracted saltwater fjords edged by cliffs soaring several thousands of feet into the air, snow-capped peaks that were swathed in mists, tidewater estuaries, sky-blue lakes, cascading waterfalls making their way into the deep freshwater lakes, and seemingly endless evergreen forests. All of a sudden, on our way back to the mainland, the pilot made an exhilarating water landing right in the midst of a valley! While halting on a rock formation in the crystal clear water, it was here
Cnidaria is a large phylum composed of some of the most beautiful of all the salt and freshwater organisms: the true jellyfish, box jellyfish, coral and sea anemones, and hydra. Although Cnidaria is an incredibly diverse group of animals, there are several traits that link them together. Most cnidarians are dipoblastic, which means that they are composed of only two layers of cells. The outer layer is known as the ectoderm or epidermis, and the inner layer is known as the endoderm or gastrodermis
