Arari River (Pará)
The Arari River () is a river of Marajó, which itself is an island in the mouth of the Amazon. It is located in the state Pará in northern Brazil. The river originates in the south of Lake Arari. Here it flows through swamp areas called ''mondongos'' that are normally flooded during the wet season. The beginning of its course is rather winded, becoming more straight after passing Cachoeira do Arari. Here the river is covered with aninga plants, giving it a dark and muddy aspect. Close to its mouth in Marajó Bay the river widens and its banks are more rocky. Numerous lakes line the banks of the river, particularly in the middle and downstream sections, the largest being around long and wide. The Arari connects to the Marajó-Açu River through a stream called Furo das Laranjeiras. Depending on seasonal changes of the water level in Marajó Bay, the river sometimes flows in the opposite direction for part of its course. This introduces a seasonality in all its physical and ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hoplosternum Littorale
''Hoplosternum littorale'' is a species of catfish (order Siluriformes) belonging to the Callichthyinae subfamily of the family Callichthyidae. It is known as tamuatá in Brazil, atipa in French Guiana, hassa in Guyana, kwi kwi (or kwie kwie'' in Suriname, cascadu or cascadura in Trinidad and Tobago, and busco or currito in Venezuela. Description ''H. littorale'' is armor-plated and dorso-ventrally compressed. The fish will grow in length up to 24.0 centimetres (9.4 in) TL. Males grow to a larger average and maximum size than females and, during the reproductive season, develop fat deposits in the pectoral fin and an elongated recurved pectoral spine that often assumes a reddish colour. Males with recurved pectoral spines are not found outside of the reproductive period. Distribution ''H. littorale'' has the widest distribution of any callichthyid.

Water Buffalo
The water buffalo (''Bubalus bubalis''), also called domestic water buffalo, Asian water buffalo and Asiatic water buffalo, is a large bovid originating in the Indian subcontinent and Southeast Asia. Today, it is also kept in Italy, the Balkans, Australia, North America, South America and some African countries. Two extant Type (biology), types of water buffalo are recognized, based on Morphology (biology), morphological and Ethology, behavioural criteria: the river buffalo of the Indian subcontinent and further west to the Balkans, Egypt and Italy; and the swamp buffalo from Assam in the west through Southeast Asia to the Yangtze Valley of China in the east. The wild water buffalo (''Bubalus arnee'') is most probably the ancestor of the domestic water buffalo. Results of a phylogenetic study indicate that the river-type water buffalo probably originated in western India and was domesticated about 6,300 years ago, whereas the swamp-type originated independently from Mainland Sou ...

Trophic State Index
The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. Under the TSI scale, water bodies may be defined as: * oligotrophic (TSI 0–40, having the least amount of biological productivity, "good" water quality); * mesotrophic (TSI 40–60, having a moderate level of biological productivity, "fair" water quality); or * eutrophic to hypereutrophic (TSI 60–100, having the highest amount of biological productivity, "poor" water quality). The quantities of nitrogen, phosphorus, and other biologically useful nutrients are the primary determinants of a water body's TSI. Nutrients such as nitrogen and phosphorus tend to be limiting resources in standing water bodies, so increased concentrations tend to result in increased ...

Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extent of water pollution and condition of drinking water. Water quality has a significant impact on water supply and often determines supply options. Impacts on public health Over time, there has been increasing recognition of the importance of drinking water quality and its impact on public health. This has led to increasing protection and management of water quality.

Turbidity
Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of both water clarity and water quality. Fluids can contain suspended solid matter consisting of particles of many different sizes. While some suspended material will be large enough and heavy enough to settle rapidly to the bottom of the container if a liquid sample is left to stand (the settable solids), very small particles will settle only very slowly or not at all if the sample is regularly agitated or the particles are colloidal. These small solid particles cause the liquid to appear turbid. Turbidity (or haze) is also applied to transparent solids such as glass or plastic. In plastic production, haze is defined as the percentage of light that is deflected more than 2.5° from the incoming light direction. Causes and effects Turbidity in open water may be ca ...

Montrichardia Linifera
''Montrichardia linifera'', also known under the common name aninga, is a tropical plant native to South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion o .... The aquatic species is a helophyte and can grow up to seven meters in height. The plant often grows in monospecific stands and thickes along rivers, lakes and other wetlands. ''M. linifera'' can be differentiated from the similar '' M. arborescens'' by several characteristics, including having a spathe tube that is greenish-white internally and a spathe blade that is yellowish externally, while ''M. arborescens'' has a spathe-tube that is reddish internally and a spathe-blade that is green externally.

Lake Arari
Lake Arari () is a lake of Marajó, which itself is an island in the mouth of the Amazon. It is located in the state Pará in northern Brazil, divided between the municipalities Cachoeira do Arari and Santa Cruz do Arari. Slightly to the north-east lies Lake Guajará. Lake Arari has an ellipsoid shape, oriented in the north-south direction. The lake can be considered the largest depression ob the island Marajó. Geological surveys identify it as the remainder of a much larger lake that existed in the past. The waters of the lake are generally muddy in the dry season. During the wet season, the area and depth of the lake change considerably because of intensive flooding of the surrounding areas. The waters become more clear and the lake is visited by boto dolphins, manatees and piracuru fish. Caimans, snakes and poraquê electric eels can also be found, as well as various types of birds, such as scarlet ibises and herons. The lake is fed in the north by the Jenipapucu River ...

Mondongos
The mondongos are low-lying swamp fields in the north of the island Marajó in the Brazilian state Pará. They are flooded during the wet season, which occurs between January and May. The mondongos occur in the transition zone between the tropical rainforest on the west of the island and the savannas in the east. They stretch for around . The mondongos are situated on an old arm of the Amazon River that crossed the island Marajó when it was still forming. A ridge of sandstone separates them from the current main channel of this river. According to Ferreira Penna, the mondongos were created when the Amazon deposited sediments against this ridge. The many streams in the area have tides that are influenced by the Amazon, not by the Pará River. The mondongos are largely covered with swamp rice grass and water hyacinths. Their roots form a dense mass that makes the area difficult to thread. The edges of the mondongos, as well as the banks of the many streams are lined with '' anin ...
