Western Pond Turtle
The Western pond turtle (''Actinemys marmorata''), also known commonly as the Pacific pond turtle is a species of small to medium-sized turtle in the family Emydidae. The species is endemic to the western coast of the United States and Mexico, ranging from western Washington state to northern Baja California. It was formerly found in Canada (in British Columbia), but in May 2002, the Canadian Species at Risk Act listed the Pacific pond turtle as being extirpated. Taxonomy and systematics Its genus classification is mixed. ''Emys'' and ''Actinemys'' were used among published sources in 2010. It was known by several names in the Indigenous languages of its range, including kʰá:wanaka: (Northeastern Pomo), kʰa:wana (Southern Pomo), and ʔaləšək (Lushootseed). Description The dorsal color of ''A. marmorata'' is usually dark brown or dull olive, with or without darker reticulations or streaking. The plastron is yellowish, sometimes with dark blotches in the centers of the scut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpaugh, California
Alpaugh is a census-designated place (CDP) in Tulare County, California, United States. The population was 1,026 at the 2010 census, up from 761 at the 2000 census. It is named for John Alpaugh, one of the officers of the Home Extension Colony which reclaimed (or land speculated on) the land the town is built on. Geography According to the United States Census Bureau, the CDP has a total area of , all of it land. The site is located on the historic shoreline of Tulare Lake, once the largest freshwater lake in the USA outside of the Great lakes. Other towns built on its historic shores include Lemoore and Kettleman City. Despite being on the edge of the ancient Tulare lakebed, the town is without access to safe drinking water, as high levels of Arsenic are found in the municipal water supply. Locals are forced to drink, cook and bathe using bottled water or expose themselves to this hazard. History Alpaugh's location (once also called Hog Island, Root Island, and Atwell's Isla ...

Tulare Lake
Tulare Lake () (Spanish: ''Laguna de Tache'', Yokuts: ''Pah-áh-su'') is a freshwater dry lake with residual wetlands and marshes in the southern San Joaquin Valley, California, United States. After Lake Cahuilla disappeared in the 17th century, Tulare Lake was the largest freshwater lake west of the Mississippi River and the second-largest freshwater lake entirely in the United States (as parts of the Great Lakes belong to Canada), based upon surface area. A remnant of Pleistocene-era Lake Corcoran, Tulare Lake dried up after its tributary rivers were diverted for agricultural irrigation and municipal water uses. The lake was named for the tule rush ''(Schoenoplectus acutus)'' that lined the marshes and sloughs of its shores. The lake was part of a partially endorheic basin, at the south end of the San Joaquin Valley, where it received water from the Kern, Tule, and Kaweah Rivers, as well as from southern distributaries of the Kings. It was separated from the rest of the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Dorsum (biology)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek language, Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axis, anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lushootseed
Lushootseed (txʷəlšucid, dxʷləšúcid), also Puget Salish, Puget Sound Salish or Skagit-Nisqually, is a language made up of a dialect continuum of several Salish tribes of modern-day Washington state. Lushootseed is one of the Coast Salish languages, one of two main divisions of the Salishan language family. Its pre-contact range extended from modern-day Olympia, Washington to Vancouver, British Columbia, spoken by roughly 12 thousand at its peak. The dialects of the language can be split into two categories: northern and southern, which can further be split into dialects spoken by the individual peoples who spoke it. Today, it is mostly used in heritage and symbolic purposes, like on signage or place names. It is seldom spoken today, and is classified as Critically Endangered by the UNESCO Atlas of the World’s Languages in Danger. Phonology Lushootseed has a complex consonantal phonology and 4 vowel phonemes. Along with more common voicing and labialization contrasts, ...

Southern Pomo
Southern Pomo is one of seven mutually unintelligible Pomoan languages which were formerly spoken and is currently spoken by the Pomo people in Northern California along the Russian River and Clear Lake. The Pomo languages have been grouped together with other so-called Hokan languages. Southern Pomo is unique among the Pomo languages in preserving, perhaps, the greatest number of syllables inherited from Proto-Pomo (the proto-language from which all seven Pomo languages descend). The speakers The speakers of Southern Pomo were never a unified political group; rather, they were spread across a number of villages and spoke slightly different dialects. Southern Pomo speakers did not have a name for their language or themselves. As the southernmost of the Pomo, the speakers of the language were the first to suffer the ravages of Spanish and, later, U.S. invasion. Southern Pomo speakers were used by the Spanish to construct the last of the California missions. The damage done duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeastern Pomo
Northeastern Pomo, also known as Salt Pomo, is a Pomoan language of Northern California. There are no living fluent speakers. It was spoken along Stony Creek, a tributary of the Sacramento River. Northeastern was one of seven mutually unintelligible Pomoan languages spoken in Northern California. Unlike the other six Pomoan languages(going to north to south: Northern Pomo, Central Pomo, Eastern Pomo, Southeastern Pomo, Kashaya Pomo, Southern Pomo), Northeastern Pomo was not spoken in an area immediately contiguous with any other Pomoan-speaking area. Northeastern Pomo speakers were ringed by speakers of Yuki, Nomlaki, and Patwin; Yuki is unrelated to Pomoan or Nomlaki and Patwin, both of which are within the Wintu language family.
