The Philippines is home to many natural lakes which are closely related to volcanic and tectonic activity as well as artificial lakes or reservoirs that have resulted from the damming of rivers for hydroelectric activity. It is one of the diverse countries in the world in terms of varied and wide array of flora and fauna which are endemic and archipelagic landscapes and seascapes. Aside from their recreational and aesthetic qualities, many lakes are important habitats for marine life and food sources. Other lakes play a part in water-supply, hydro-electric power or flood control.
Lake Mainit is geographically located near the extreme northern tip of Mindanao Island. Its name is derived from Mainit River that traverses the - 3 - lake and has

Theconsequent decline of the quality of living of the people indicated the weakening of the ecosystem services such as the occurrence of landslides, soil erosion, siltation, climate change, floods and many others, have threatened lives and properties which emanated from the loss of biodiversity. Indeed, the relationship between the forest habitats and biodiversity is directly proportional and interrelated to the ecosystem …show more content…
This study asses the composition and distribution of bats and its association to its habitat. The result of this study can be utilize and serve as a baseline in the implementation of the protection and conservation of the area. This study also provide awareness to the Local Government Unit (LGU), other agencies and concerned individuals on its current conservation status and create a more diverse and healthy
Matanuska River drains an extensive amount of valley in the south which is the main reason on how the river got the name. Shem Pete states in his journal that in the 1860’s, the name Matanuska does not show up on the first ninteenth-century map, so it was named the Knik River instead of Matanuska River. Shem Pete also states how no one used boats on the Matanuska River, mostly because the trail was too cold, swift and rocky. Matanuska river also has big standing waves and holes along some sections of the trail, which causes overhanging on the lower reaches and upriver winds. Most travelers came to the river from late fall until spring when it was easier to move their supplies on sleds.
Environmental Science and Sustainability (SCI201 -1504A -07) Instructor: Trena Woolridge Unit 4- Discussion Board Amanda Kranning October 27, 2015 Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.(Cloern, Krantz, & Hogan, 2013) Eutrophication forms when an abundance of nitrogen and phosphorus increases growth within an environment.
Apart from its large mass, the great lakes is an important recreational and economic resource to the United States and Canada. According to Environment
The other type of river that resulted because of glaciation is the meandering river. Wisconsin has such a flat terrain where the glacier used to lie, that meandering rivers are very common. These rivers are characterized by their curviness, which sometimes curve so much that they form oxbow lakes: a u-shaped body of water (Ice age geology, n.d.). Meandering rivers and oxbow lakes are pictured
In the winter, the river flows at about 1,700 cfs due to the glacial runoff and in the summer the flow decreases as the temperature increases. Since meandering channels form on low slopes, the velocity is low and must flow through easily eroded bedrock which would be low sediments. The strongest current is on the cut bank where the larger rocks settle and in the point bar, where the slowest velocity occurs, is where deposition of small sediment falls. The river has low energy and therefore is a wide valley where the energy is directed side by side and eventually forms the meandering
Due to fluctuating climate, which, in turn, changes temperature and precipitation, the composition of forests and meadows were altered. This new plant arrival that occurs as a result of changing conditions is known as succession. As a result of the changing composition of forests and nature, the species of plants and animals living there also changes.
This is due to the river growing larger, as it travels downstream. Most rivers and creeks grow larger as they flow downstream. The difference with the Mississippi is the amount of water being transported through it. The Mississippi has more tributaries than most. What this means for flooding is that it will be increased, the lower you travel.
The economic temptation encourages the practice of monoculture instead of running a diverse farm. Species are forced to leave and clear the land for corn plantation. However, biodiversity is vital for sustainable development because every livestock and crops are completing the food chain. The vanishing species, caused by subsidy on corn, provoke the imbalance of ecosystem and environmental crisis, like global warming. Eventually, it affects the whole city, or even the
Through this incredible work, there are now over 1,000 of these magnificent animals back in the wild and thousands more looked after by zoos worldwide. ”(CSA, page 1) “In 1975 the wild population of the Puerto Rican parrot was down to just 13 birds. Part of the problem is that the parrots are particularly vulnerable to hurricanes: When careful protection had the wild population up to 47 in 1989, more than half were wiped out by Hurricane
Lake Superior by its surface area it is the world’s largest freshwater lake. Out of the Great Lakes it is the deepest lake of them all. Lake Superior also contains 10% of all the freshwater supply on the earth. Lake Superior also contains more water that all the other great lakes by a lot. There also is enough water to flood North & South America by a depth of 1 foot.
Deforestation results in the loss of biodiversity Deforestation is having its most devastating effect on biodiversity in tropical rainforests. The destruction of millions of hectares of forests by human activities means: • The removal of the bases of numerous food webs • The loss of habitats for many species of flora and
In some case “human activities have been and are continuing to alter the environment on local and global scales. Many of these changes are leading to dramatic changes in the biotic structure and piece of ecological communities, either from the mislaying of species or from the introduction of exotic species. Such alterations can preferable change the ways in which ecosystems work. Altered biodiversity has led to widespread cover for a number of both market (e.g., ecotourism, “mining” for medicines) and non-market (e.g., ethical, aesthetic) explanation” (Barbier et al. 1995, Kunin and Lawton 1996, Schwartz et al. 2000, Hector et al. 2001b, Minns et al. 2001, Sax and Gaines 2003).
Sustainable forest management requires three major criteria which are the maintenance of ecological processes within the forest (soil formation, energy flow, biogeochemical cycles (carbon, nutrient and hydrological cycles), maintenance of biodiversity of forest, improving the net social benefits derived from the mixture of forest uses within the constraints by considering the future. Forest provides habitats for more than half of the fauna and flora on the Earth (SCBD, 2001). Forest biome plays an important role in mitigating climate change by serving as carbon sinks (Hassan et al., 2005). Forest land is the most fundamental natural resources which become reduced mainly due to anthropogenic pressures. For proper management of land, it is essential to have information about existing land cover and about the naturalness of the land.
When animals lose their habitat (Anadiplosis), they are not accustomed to their new surroundings and could potentially go extinct. Species depend on forests to survive and when the forests are cut down, the animals have nothing left. Forests are heavily depended on for resources and ways of life. The Pachamama Alliance Organization claims that, “the tropical rainforests of South America are responsible for 20% of earth’s oxygen.” This proves the earth relies greatly on forests and may suffer consequences because of the speedy rate trees are being cut
Introduction By the year 2025, the Philippines is believed to be brought to a water crisis if no new sources of water are developed or found to meet the growing demand of the citizens. (Sapnu, R., Balabo, D., & Cervantes, D., 2007) "There is a Japan International Cooperation Agency study that says that if we will not conserve water, there may be some problems. But of course we can always start conserving now and look for other sources," Lopez (2013) said. Studies have shown how water conservation and appropriate water utilization are significant as early as today.
