Stygobromus Canadensis
''Stygobromus canadensis'', the Castleguard Cave stygobromid, is a species of amphipod in the Crangonyctidae family and ''Stygobromus'' genus. It is endemic to Castleguard Cave in Alberta, Canada. It was first described by John Holsinger in 1980. It is currently listed as critically imperiled by NatureServe. The presence of this species has led to the cave's designation as a Key Biodiversity Area.

Amphipoda
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stygobromus
''Stygobromus'' is a genus of amphipod crustaceans that live in subterranean habitats. As well as a large number of species in North America, a smaller number of species are also known from Eurasia. Most of the North American species live in areas which were not covered by the Laurentide Ice Sheet, although a few species seem to have survived under the ice. A number of species are on the IUCN Red List as endangered species (EN) or vulnerable species (VU); all the listed species are endemic to the United States. One species, '' S. lucifugus'', is extinct. ''Stygobromus'' includes the following species: *'' Stygobromus abditus'' Holsinger, 1978 (Virginia) *'' Stygobromus ackerlyi'' Holsinger, 1978 (Georgia) *'' Stygobromus alabamensis'' (Stout, 1911) *'' Stygobromus albapinus'' Taylor & Holsinger, 2011 (Nevada) *'' Stygobromus allegheniensis'' (Holsinger, 1967) (New York to West Virginia) *'' Stygobromus ambulans'' (F.

Castleguard Cave
Castleguard Cave is a limestone cave located at the north end of Banff National Park in the Rocky Mountains of Alberta, Canada. With of surveyed passages (as of 2007), it is Canada's longest cave, and its fifth deepest at . Castleguard Cave ascends gently from its entrance and terminates beneath the Columbia Icefield. General information Castleguard Cave is modest in size compared to other great caves of the world, but nevertheless is well known amongst cavers and speleologists internationally. It is the subject of a film and a coffee-table book, and is mentioned in most cave reference books in print. This attention is due in part to its magnificent, remote mountain setting. Its location within a protected area in a national park prohibits motorized ground access, and the risk of flooding in its entrance has limited most explorations to mid or late winter, so cavers must access it via a ski with towed sleds, or by helicopter. This feeling of remoteness is compounded by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Key Biodiversity Area
The Key Biodiversity Areas (KBA) approach helps to identify and designate areas of international importance in terms of biodiversity conservation using globally standardised criteria. KBAs extend the Important Bird Area (IBA) concept to other taxonomic groups and are now being identified in many parts of the world, by a range of organisations. Examples include Important Plant Areas (IPAs), Ecologically and Biologically Significant Areas (EBSAs) in the High Seas, Alliance for Zero Extinction (AZE) sites, Prime Butterfly Areas, Important Mammal Areas and Important Sites for Freshwater Biodiversity, with prototype criteria developed for freshwater molluscs and fish and for marine systems. The determination of KBAs often brings sites onto the conservation agenda that hadn't previously been identified as needing protection due to the nature of the two non-exclusive criteria used to determine them; vulnerability; and irreplaceability. The KBA global standard was published in 2016. Obje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daily Hive
''Daily Hive'', formerly known as ''Vancity Buzz'', is a Canadian online newspaper based in Vancouver, British Columbia. It began digital publishing in 2008 and became Western Canada's largest online-only publication by 2016. In September 2022, ZoomerMedia announced a deal to acquire ''Daily Hive'' for $16.4 million. History The site began its publishing in 2008 under the name ''Vancity Buzz'' and was founded by Manny Bahia and Karm Sumal. The name was changed to ''Daily Hive'' in 2016 when the company expanded nationally. Concurrently with its rebranding as ''Daily Hive'', the publication expanded to Toronto and Montreal. In November 2017, ''Daily Hive'' deleted many of their posts on their official Instagram account as a form of viral marketing, inspired by Taylor Swift's similar publicity stunt earlier in the year. They then posted images of the word "Nude". This stunt caused growth in their social media presence and gained them more followers than before. ID Agency I ...

Endemic Fauna Of Canada
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
