Monkey River
Monkey River is a coastal watercourse in southern Belize that rises in the Maya Mountains and discharges to the Caribbean Sea near Monkey River Town. One of Belize's major rivers, Monkey River has northern headwaters which originate in the Cockscomb Basin Wildlife Sanctuary, where the Swasey Branch drains the East Basin of that wildlife sanctuary. Further south, the Bladen Branch watercourse drains the eastern slopes of the Maya Mountains including the ancient Mayan settlement areas of Lubaantun and Nim Li Punit. These two watercourses join to form the Monkey River approximately 16 kilometres upstream from the mouth of the Monkey River. The Monkey River is readily navigated throughout the year using small boats, but navigation above the major confluence (of Bladen and Swasey Branches) becomes more difficult due to lack of depth when the dry season starts about February. Habitats in this watershed provide cover for such diverse species as the ocelot, jaguar, Guatemalan black how ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morelet's Crocodile
Morelet's crocodile ''(Crocodylus moreletii)'', also known as the Mexican crocodile or Belize crocodile, is a modest-sized crocodilian found only in fresh waters of the Atlantic regions of Mexico, Belize and Guatemala. It usually grows to about in length. It is a Least Concern species. The species has a fossil record in Guatemala. Taxonomy and etymology Morelet's crocodile was first described in 1850 in Mexico by the French naturalist Pierre Marie Arthur Morelet. The species was subsequently named after him. It was long confused with the American and Cuban crocodiles because of similar characteristics and an ambiguous type locality. It was not generally accepted as a separate species until the 1920s. Evolution The genus '' Crocodylus'' likely originated in Africa and radiated outwards towards Southeast Asia and the Americas, although an Australia/Asia origin has also been considered. Phylogenetic evidence supports ''Crocodylus'' diverging from its closest recent relative, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 caused by growth of phyto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of the Fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belize Barrier Reef
The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly offshore in the north and in the south within the country limits. The Belize Barrier Reef is a long section of the Mesoamerican Barrier Reef System, which is continuous from Cancún on the north-eastern tip of the Yucatán Peninsula through the Riviera Maya and down to Honduras, making it the second largest coral reef system in the world after the Great Barrier Reef in Australia. It is Belize's top tourist destination, popular for scuba diving and snorkeling and attracting almost half of its 260,000 visitors. It is also vital to the country's fishing industry.Harrabin, Roger.

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

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, extend of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options. Categories The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for potability, industrial/domestic use, or restoration (of an environment/ecosystem, generally for health of human/aquatic life). Human consumption Contaminants that may be in untreated water include microorganisms such as viruses, protozoa and bacteria; inorganic ...

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sp ...

Gulf Of Honduras
The Gulf or Bay of Honduras is a large inlet of the Caribbean Sea, indenting the coasts of Belize, Guatemala, and Honduras. From north to south, it runs for approximately 200 km (125 miles) from Dangriga, Belize, to La Ceiba, Honduras. The inner Gulf of Honduras is lined by the Belize Barrier Reef which forms the southern part of the 900 km (600 mile) long Mesoamerican Barrier Reef System, the second-largest coral reef system in the world. The Belize Barrier Reef includes a number of small islands, called cays, and collectively known as the Pelican Cays. The Gulf of Honduras is marked by complex dynamics of coastal and open waters, and ocean currents, which have produced a very diverse and unique ecosystem with a wide variety of coastal marine waters, including coastline estuaries, barrier beaches, lagoons, intertidal salt marshes, mangrove forests, seagrass beds, keys and barrier reefs. The gulf receives the runoff from the watersheds of 12 rivers with an est ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
