Lake Waccamaw
Lake Waccamaw is a fresh water lake located in Columbus County in North Carolina. It is the largest of the natural Carolina Bay lakes. Although bay trees (''Magnolia virginiana L.'', ''Gordonia lasianthus Ellis'', and ''Persea'') are present within many Carolina Bays, the term "bay" does not refer to the trees but comes instead from an early science publication by Glenn (1895), who used the word "bay" (which he described as "lake-like expanses") to refer to these features near the town of Darlington, South Carolina. Lake Waccamaw is fed by four creeks: First, Second, Third, and Big creeks. The outlet forms the Waccamaw River which flows south-southwest to empty into the Atlantic Ocean near Georgetown, South Carolina Geography Lake Waccamaw has a broad, flat bottom of gyttja (mud) and peat, encircled by sandy shallows and submerged sandy terraces that extend up to offshore. The lake is oval in shape, measuring roughly by , covering surface area with an average depth of and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Carolina Division Of Parks And Recreation
The State of North Carolina has a group of protected areas known as the North Carolina State Park System, which is managed by the North Carolina Division of Parks and Recreation (NCDPR), an agency of the North Carolina Department of Natural and Cultural Resources (NCDNCR). Units of the system can only be established by an act of the General Assembly of North Carolina. The park system began in 1916 when the summit of Mount Mitchell became first state park in the Southeastern United States. According to the Division of Parks & Recreation, "the State Parks Act of 1987 lists six types of units included in the NC State Parks System." These are ''State Parks'', ''State Recreation Areas'', ''State Natural Areas'', ''State Lakes'', ''State Trails'', and ''State Rivers''. All units of the system are owned and/or managed by the division, and the division leases some of the units to other agencies for operation. Most units of the park system are also components of State Nature and Hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Columbus County, North Carolina
Columbus County is a county located in the U.S. state of North Carolina, on its southeastern border. Its county seat is Whiteville. The 2020 census showed a loss of 12.9% of the population from that of 2010. As of the 2020 census, the population is 50,623. This included inmate prison population of approximately 2500. History Early history The area comprising Columbus County was originally inhabited by the Waccamaw people. Historically, the "eastern Siouans" had territories extending through the area of Columbus County prior to any European exploration or settlement in the 16th century. English colonial settlement in what was known as Carolina did not increase until the late 17th and early 18th centuries. Following epidemics of new infectious diseases, to which indigenous peoples were exposed in trading and other contact, the Waccamaw and other Native Americans often suffered disruption and fatalities when caught between larger tribes and colonists in the Tuscarora and Yama ...

Acantharchus Pomotis
The mud sunfish (''Acantharchus pomotis'') is a freshwater ray-finned fish, a sunfish from the family Centrarchidae, which widely distributed in the fresh waters along the Atlantic coast of North America, ranging from New York to Alabama. It is the only species in the genus ''Acantharchus''. Taxonomy The mud sunfish was first formally described as ''Centrarchus pomotis'' by Spencer Fullerton Baird in 1855 with the type locality given as Cedar Swamp Creek, Beesley's Point, Cape May County, New Jersey and the Hackensack River, Rockland County, New York. In 1864, Theodore Nicholas Gill placed it in its own monospecific genus ''Acantharchus'', the new genus name being a compound of the Greek words meaning "thorn" and meaning "anus". Description The mud sunfish is a small fish which can be distinguished from other members of its family by its possession of 5 or more spines in its anal fin, by having less than 15 gill rakers and in being the only species in its family which has cy ...

Trophic Level
The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way flow or a food "web". Ecological communities with higher biodiversity form more complex trophic paths. The word ''trophic'' derives from the Greek τροφή (trophē) referring to food or nourishment. History The concept of trophic level was developed by Raymond Lindeman (1942), based on the terminology of August Thienemann (1926): "producers", "consumers" and "reducers" (modified to "decomposers" by Lindeman).

Aquatic Layer
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. The ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

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] |
Alligators
An alligator is a large reptile in the Crocodilia order in the genus ''Alligator'' of the family Alligatoridae. The two extant species are the American alligator (''A. mississippiensis'') and the Chinese alligator (''A. sinensis''). Additionally, several extinct species of alligator are known from fossil remains. Alligators first appeared during the Oligocene epoch about 37 million years ago. The name "alligator" is probably an anglicized form of ', the Spanish term for "the lizard", which early Spanish explorers and settlers in Florida called the alligator. Later English spellings of the name included ''allagarta'' and ''alagarto''. Evolution Alligators and caimans split in North America during the early Tertiary or late Cretaceous (about 53 million to about 65 million years ago). The Chinese alligator split from the American alligator about 33 million years ago and probably descended from a lineage that crossed the Bering land bridge during the Neogene. The moder ...

Snail
A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name ''snail'' is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called '' slugs'', and land snails that have only a very small shell (that they cannot retract into) are often called ''semi-slugs''. Snails have considerable human relevance, including as food items, as pests, and as vectors of disease, and their shells are used as decorative objects and are incorporated into jewelry. The snail has also had some cultural significance, tending to be associated with lethargy. The sn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clam
Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Many edible clams such as palourde clams are ovoid or triangular; however, razor clams have an elongated parallel-sided shell, suggesting an old-fashioned ...

Mussel
Mussel () is the common name used for members of several families of bivalve molluscs, from saltwater and Freshwater bivalve, freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong Byssus, byssal threads ("beard") to a firm substrate. A few species (in the genus ''Bathymodiolus'') have colonised hydrothermal vents associated with deep ocean ridges. In most marine mussels the shell is longer than it is wide, being wedge-shaped or asymmetrical. The external colour of the shell is often dark blue, blackish, or brown, while the interior is silvery and somewhat nacreous. The common name "mussel" is also used for many freshwater bivalves, including the freshwater pearl mussels. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
