Laguna Madre (Mexico)
Laguna Madre is a coastal lagoon in Northeastern Mexico. It extends along the coast of Tamaulipas for over 200 km, from the Río Bravo Delta on the north to the mouth of the Soto la Marina River near La Pesca in the south. Laguna Madre is separated from the Gulf of Mexico on the east by a number of barrier islands, including Barra Los Americanos, Barra Jesús María, and Barra Soto la Marina, and is bounded on the west by the Tamaulipan mainland. It is located in the municipalities of Matamoros, San Fernando, and Soto la Marina. There is another Laguna Madre in the United States, which extends north from the Río Bravo Delta to Corpus Christi Bay and the city of Corpus Christi in southern Texas. Together the two lagoons and delta form a single ecological unit approximately in total.Tunnell, Jr. John W. and Frank W. Judd. editors. (2002). ''The Laguna Madre of Texas and Tamaulipas''.

Tamaulipas
Tamaulipas, officially the Free and Sovereign State of Tamaulipas, is a state in Mexico; one of the 31 states which, along with Mexico City, comprise the 32 federal entities of Mexico. It is divided into 43 municipalities. It is located in northeast Mexico and is bordered by the states of Nuevo León to the west, San Luis Potosí to the southwest, and Veracruz to the southeast. To the north, it has a stretch of the U.S.–Mexico border with the state of Texas, and to the east it is bordered by the Gulf of Mexico. In addition to the capital city, Ciudad Victoria, the state's largest cities include Reynosa, Matamoros, Nuevo Laredo, Tampico, and Mante. Etymology The name Tamaulipas is derived from ''Tamaholipa'', a Huastec term in which the ''tam-'' prefix signifies "place (where)". No scholarly agreement exists on the meaning of ''holipa'', but "high hills" is a common interpretation. Another explanation of the state name is that it is derived from ''Ta ma ho'lipam ...

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or " tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanderling
The sanderling (''Calidris alba'') is a small wading bird. The name derives from Old English ''sand-yrðling'', "sand-ploughman". The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific, ''alba'', is Latin for "white". It is a circumpolar Arctic breeder, and is a long-distance migrant, wintering south to South America, South Europe, Africa, and Australia. It is highly gregarious in winter, sometimes forming large flocks on coastal mudflats or sandy beaches. It is somewhat unlike other sandpipers in appearance, which has led to the suggestion that it should be placed into a monotypic genus ''Crocethia''. A more recent review (Thomas ''et al.'', 2004) indicates, however, that the sanderling is a fairly typical "stint" or small sandpiper and should be separated from the large knots with its closest relatives in a distinct genus. This bird is similar in size to a dunlin, but stouter, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Plover
The grey plover or black-bellied plover (''Pluvialis squatarola'') is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding. Taxonomy The grey plover was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa squatarola''. It is now placed with three other plovers in the genus ''Pluvialis'' that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. The genus name is Latin and means relating to rain, from ''pluvia'', "rain". It was believed that they flocked when rain was imminent. The species name ''squatarola'' is a Latinised version of ''Sgatarola'', a Venetian name for some kind of plover. The English common name used for this species differs in different parts of the world. It is generally known as "grey plover" in the Old World and "black-bellied plover" in the New World. T ...

Waterfowl
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves, the clade consisting of all other modern birds except the galliformes and paleognaths. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins, the Galliformes. These two groups only occupied two ecological niches during the Mesozoic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halodule Wrightii
''Halodule wrightii'' is an aquatic plant in the Cymodoceaceae family. It is referred to by the common names shoal grass or shoalweed, and is a plant species native to seacoasts of some of the warmer oceans of the world. ''H. wrightii'' is an herb growing in salt-water marshes in intertidal regions, often submerged at high tide but emergent at low tide.Godfrey, R. K. & J. W. Wooten. 1979. Aquatic and Wetland Plants of Southeastern United States Monocotyledons 1–712. The University of Georgia Press, Athens. Taxonomy This plant was named after Charles Wright, who was an American botanist and collector. In 1853 and 1856 Wright participated in a surveying expedition and discovered ''Halodule wrightii''. Some publications cite US specimens by the synonym, ''Halodule beaudettei'', but the two names represent the same species.

Seagrass
Seagrasses are the only flowering plants which grow in marine (ocean), marine environments. There are about 60 species of fully marine seagrasses which belong to four Family (biology), families (Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae), all in the order Alismatales (in the clade of monocotyledons). Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago. The name ''seagrass'' stems from the many species with long and narrow Leaf, leaves, which grow by rhizome extension and often spread across large "Seagrass meadow, meadows" resembling grassland; many species superficially resemble terrestrial grasses of the family Poaceae. Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Most species undergo submarine pollination and complete their life cycle underwater. While it was previously believed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove
A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parts Per Thousand
In science and engineering, the parts-per notation is a set of pseudo-units to describe the small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are * parts-per-million - ppm, * parts-per-billion - ppb, * parts-per-trillion - ppt, * parts-per-quadrillion - ppq, This notation is not part of the International System of Units - SI system and its meaning is ambiguous. Applications Parts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water. The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Therefore, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semiarid
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * mu ...
