False Map Turtle
The false map turtle (''Graptemys pseudogeographica'') is a species of turtle Endemism, endemic to the United States. It is a common pet species. Two subspecies are recognized, including the nominotypical subspecies described here. Description Also known as a "sawback" turtle, the turtle has a carapace featuring a vertebral row of low spines, and is serrated on the posterior rim. The carapace is olive to brown in color with light yellowish markings with dark borders. The plastron color varies from cream to yellow and is patterned with dark lines along the seams in juveniles. The body color of the false map turtle is grayish brown to blackish and is marked with light brown, yellow, or whitish stripes. The eye can be brown, light yellow, white, or green and is crossed with a dark bar. Narrow hooked marks behind the eye fuse with dorsal lines on the head and neck. Also, small light-colored spots occur below the eye and on the chin. Geographic range The false map turtle lives in lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is part of the narrow-headed group of map turtles, and is endemic to the southern United States. Geographic range Its distribution is limited to the Pascagoula River of Mississippi and most of its tributaries (a range it shares with the Pascagoula map turtle). Home range Males have a mean home range area of 1.12 ha (2.77 acres) and a mean home range length of . Females have a mean home range area of 5.75 ha (14.20 acres), due to nesting activities, and a mean home range length of .

Richard Vogt (herpetologist)
Richard Carl "Dick" Vogt (August 06, 1949 – January 17, 2021) was an American herpetologist based in Brazil. He was the director of the ''Centro de Estudos de Quelônios da Amazônia'' (Center for the Study of Amazonian Turtles) at the National Institute of Amazonian Research (INPA). Career Vogt received his PhD in 1978 from the University of Wisconsin-Madison, his dissertation focused on the systematics and ecology of the false map turtle (''Graptemys pseudogeographica''). The same year, he became a Postdoctoral Fellow at Carnegie Museum of Natural History in Pittsburgh. In March 2000, ''Wildlife Conservation'' magazine wrote about Vogt's work in his role as Curator of reptiles and amphibians for the Museum of INPA in Manaus. At the time, his research was focused on working with communities in Mamirauá to monitor and safeguard the population levels of both the six-tubercled Amazon River turtle (''Podocnemis sextuberculata'') and the yellow-headed sideneck turtle (''Podocnem ...

Sexually Dimorphic
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mississippi River
The Mississippi River is the main stem, primary river of the largest drainage basin in the United States. It is the second-longest river in the United States, behind only the Missouri River, Missouri. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's Drainage basin, watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky Mountains, Rocky and Appalachian Mountains, Appalachian mountains. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada.

Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes spanning the Canada–United States border. The five lakes are Lake Superior, Superior, Lake Michigan, Michigan, Lake Huron, Huron, Lake Erie, Erie, and Lake Ontario, Ontario (though hydrologically, Lake Michigan–Huron, Michigan and Huron are a single body of water, joined at the Straits of Mackinac). The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The lakes connect to the Atlantic Ocean via the Saint Lawrence River, and to the Mississippi River basin through the Illinois Waterway. The Great Lakes are the largest group of freshwater lakes on Earth by total area and the second-largest by total volume. They contain 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface f ...

Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic animal, aquatic invertebrate animals, nearly all living in sedentary Colony (biology), colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeder, filter feeding. Most Marine (ocean), marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the Stenolaemata, marine bryozoans (Stenolaemata), Phylactolaemata, freshwater bryozoans (Phylactolaemata), and Gymnolaemata, mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. Originally all of the crown group Bryozoa were colonial, but as an adaptation to a mesopsammal (interstitial spaces in marine sand) life or to deep-sea habitats, secondarily solitary forms have since evolved. Solitary species have been described i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Ecosystem
River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.Angelier, E. 2003. Ecology of Streams and Rivers. Science Publishers, Inc., Enfield. Pp. 215."Biology Concepts & Connections Sixth Edition", Campbell, Neil A. (2009), page 2, 3 and G-9. Retrieved 2010-06-14. River ecosystems are part of larger watershed networks or catchments, where smaller headwater streams drain into mid-size streams, which progressively drain into larger river networks. The major zones in river ecosystems are determined by the river bed's gradient or by the velocity of the current. Faster moving turbulent water typically contains greater concentrations of dissolved oxygen, which supports greater biodiversity than the slow-moving water of pools. These distinctions form the basis for the division of rivers into upland and lowla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
