Northern River Otter
The North American river otter (''Lontra canadensis''), also known as the northern river otter and river otter, is a semiaquatic mammal that lives only on the North American continent throughout most of Canada, along the coasts of the United States and its inland waterways. An adult North American river otter can weigh between . The river otter is protected and insulated by a thick, water-repellent coat of fur. The North American river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land. It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems. The den typically has many tunnel openings, one of which generally allows the otter to enter and exit the body of water. Female North American river otters give birth in these burrows, producing litters of one to six young. North American river otters, like most predators, prey upon the most readil ...

Freshwater Snails
Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. '' Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. Freshwater snails are indirectly among the deadliest animals to humans, as they carry parasitic worms that cause schistosomiasis, a disease estimated to kill between 10,000 and 200,000 people annually. There are thousands of known species, and at least 33–38 independent lineages of gastropods have successfully colonized freshwater environments ...

Naturalism (philosophy)
In philosophy, naturalism is the idea that only Scientific law, natural laws and forces (as opposed to supernatural ones) operate in the universe. In its primary sense, it is also known as ontological naturalism, metaphysical naturalism, pure naturalism, philosophical naturalism and antisupernaturalism. "Ontological" refers to ontology, the philosophical study of what exists. Philosophers often treat naturalism as equivalent to materialism, but there are important distinctions between the philosophies. For example, philosopher Paul Kurtz argued that nature is best accounted for by reference to Matter, material principles. These principles include mass, energy, and other Physical property, physical and Chemical property, chemical properties accepted by the scientific community. Further, this sense of naturalism holds that spirits, Deity, deities, and ghosts are not real and that there is no "Teleology, purpose" in nature. This stronger formulation of naturalism is commonly ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

European Colonization Of The Americas
During the Age of Discovery, a large scale colonization of the Americas, involving a number of European countries, took place primarily between the late 15th century and the early 19th century. The Norse explored and colonized areas of Europe and the North Atlantic, colonizing Greenland and creating a short-term settlement near the northern tip of Newfoundland circa 1000 AD. However, due to its long duration and importance, the later colonization by the European colonial powers of the Americas, after Christopher Columbus’s voyages, is more well-known. During this time, the European colonial empires of Spain, Portugal, Great Britain, France, Russia, the Netherlands, Denmark, and Sweden began to explore and claim the Americas, its natural resources, and human capital, leading to the displacement, disestablishment, enslavement, and even genocide of the Indigenous peoples in the Americas, and the establishment of several settler colonial states. The rapid rate at which so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...

Catfish (or catfishes; order (biology), order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are common name, named for their prominent barbel (anatomy), barbels, which resemble a cat's whiskers, though not all catfish have prominent barbels or "whiskers", with some seemingly not having them. Siluriformes as a whole are Fish scale, scale-less, with neither the Armoured catfish, armour-plated nor the naked species having scales.

Catostomidae
The Catostomidae are the suckers of the order (biology), order Cypriniformes, with about 78 species in this family (biology), family of freshwater fishes. The Catostomidae are almost exclusively native to North America. The only exceptions are ''Catostomus catostomus,'' found in both North America and Russia, and ''Myxocyprinus asiaticus'' found only in China. In the Ozarks they are a common food fish and a festival is held each year to celebrate them. The bigmouth buffalo, ''Ictiobus cyprinellus,'' can reach an age up to 127 years, making it the oldest known freshwater teleost by more than 50 years. Description and biology The mouths of these fish are most commonly located on the underside of their head (Fish anatomy#Head, subterminal), with thick, fleshy lips.
