Réghaïa Lake
Réghaïa lake is located in the commune of Reghaïa, Réghaïa, Algeria, 29 km east of Algiers. It collects water from a watershed of 842 km², from which the Oued Réghaïa flows. The lake, together with the Réghaïa forest, was recognized as a Ramsar site on June 4, 2003. Location Réghaïa lake is located 29 km east of Algiers Province, Algiers. It is located in the commune of Reghaïa, Réghaïa in the Mitidja region of Basse Kabylie. Description Réghaïa lake corresponds to the estuary of the Oued Réghaïa, whose mouth is blocked by a dune belt. Some 600 meters upstream from the Mediterranean Sea, Mediterranean, an artificial dyke retains the permanent waters of the marshland site. This maritime marsh has gently sloping banks. History Before the 1930s, when the dunes held back the Oued Réghaïa and its bed had not been deepened, there was a natural marsh rich in waterfowl, but the quest for new farmland led to the wadi being drained by pumping, draining and plant ...

Carnivore
A carnivore , or meat-eater (Latin, ''caro'', genitive ''carnis'', meaning meat or "flesh" and ''vorare'' meaning "to devour"), is an animal or plant Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with c ... whose nutrition and energy requirements are met by eating, consumption of animal tissue (biology), tissues (mainly muscle, adipose tissue, fat and other soft tissues) as food, whether through predation or scavenger, scavenging. Nomenclature Mammal order The technical term for mammals in the order (biology), order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbivore
A herbivore is an animal anatomically and physiologically evolved to feed on plants, especially upon vascular tissues such as foliage, fruits or seeds, as the main component of its diet. These more broadly also encompass animals that eat non-vascular autotrophs such as mosses, algae and lichens, but do not include those feeding on decomposed plant matters (i.e. detritivores) or macrofungi (i.e. fungivores). As a result of their plant-based diet, herbivorous animals typically have mouth structures ( jaws or mouthparts) well adapted to mechanically break down plant materials, and their digestive systems have special enzymes (e.g. amylase and cellulase) to digest polysaccharides. Grazing herbivores such as horses and cattles have wide flat- crowned teeth that are better adapted for grinding grass, tree bark and other tougher lignin-containing materials, and many of them evolved rumination or cecotropic behaviors to better extract nutrients from plants.

Avifauna
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have ...

Ornithology
Ornithology, from Ancient Greek ὄρνις (''órnis''), meaning "bird", and -logy from λόγος (''lógos''), meaning "study", is a branch of zoology dedicated to the study of birds. Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guild (ecology), guilds, insular biogeography, phylogeography, and bird conservation, conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories.

Farmland
Agricultural land is typically land ''devoted to'' agriculture, the systematic and controlled use of other forms of lifeparticularly the rearing of livestock and production of cropsto produce food for humans. It is generally synonymous with both farmland or cropland, as well as pasture or rangeland. The United Nations Food and Agriculture Organization (FAO) and others following its definitions, however, also use ''agricultural land'' or as a term of art, where it means the collection of: * '' arable land'' (also known as ''cropland''): here redefined to refer to land producing crops requiring annual replanting or fallowland or pasture used for such crops within any five-year period * '' permanent cropland'': land producing crops which do not require annual replanting * ''permanent pastures'': natural or artificial grasslands and shrublands able to be used for grazing livestock This sense of "agricultural land" thus includes a great deal of land not devoted to agricultural use ...

Flood Control
Flood management or flood control are methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the ''structural'' type (i.e. flood control) and of the ''non-structural'' type. Structural methods hold back floodwaters physically, while non-structural methods do not. Building hard infrastructure to prevent flooding, such as flood walls, is effective at managing flooding. However, it is best practice within landscape engineering to rely more on soft infrastructure and Nature-based solutions, natural systems, such as marshes and Floodplain, flood plains, for handling the increase in water. Flood management can include ''flood risk management,'' which focuses on measures to reduce risk, vulnerability and exposure to flood disasters and providing risk analysis through, for example, flood ris ...

Summer
Summer or summertime is the hottest and brightest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, daylight hours are the longest and darkness hours are the shortest, with day length decreasing as the season progresses after the solstice. The earliest sunrises and latest sunsets also occur near the date of the solstice. The date of the beginning of summer varies according to definition, climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Etymology The modern English ''summer'' derives from the Middle English ''somer'', via the Old English ''sumor''. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with 21 June or 21 December.

Winter
Winter is the coldest and darkest season of the year in temperate and polar climates. It occurs after autumn and before spring. The tilt of Earth's axis causes seasons; winter occurs when a hemisphere is oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. Winter typically brings precipitation that, depending on a region's climate, is mainly rain or snow. The moment of winter solstice is when the Sun's elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole. The day on which this occurs has the shortest day and the longest night, with day length increasing and night length decreasing as the season progresses after the solstice. The earliest sunset and latest sunrise dates outs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
