Texella Cokendolpheri
The Cokendolpher cave harvestman, ''Texella cokendolpheri'', is a species of cave-living harvestman (daddy longlegs) native to Bexar County, Texas. The original common name, the Robber Baron Cave harvestman, stemmed from the cave which the harvestman inhabits. The scientific name and the current common name honor the prominent arachnologist, James Cokendolpher, who identified the species. ''T. cokendolpheri'' is one of twenty-eight species within the North American harvestman genus ''Texella''. The first formal description of the harvestman took place in 1992 and the species’ listing under the Endangered Species Act followed eight years later.Petition to M.

Cave Arachnids
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganism ...

Harvestmen
The Opiliones (formerly Phalangida) are an Order (biology), order of arachnids Common name, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant taxon, extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their Phylogenetics, phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata ( ...

Endemism
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causin ...

Cave Crickets
The orthopteran family Rhaphidophoridae of the suborder Ensifera has a worldwide distribution. Common names for these insects include cave wētā, cave crickets, camelback crickets, camel crickets, Hogan bugs, spider crickets (sometimes shortened to "criders", or "land shrimp" or "sprickets",) and sand treaders. Those occurring in New Zealand, Australia, and Tasmania are typically referred to as jumping or cave wētā. Most are found in forest environments or within caves, animal burrows, cellars, under stones, or in wood or similar environments. All species are flightless and nocturnal, usually with long antennae and legs. More than 500 species of Rhaphidophoridae are described. The well-known field crickets are from a different superfamily (Grylloidea) and only look vaguely similar, while members of the family Tettigoniidae may look superficially similar in body form. Description Most cave crickets have very large hind legs with "drumstick-shaped" femora and equally long, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Imported Fire Ant
The red imported fire ant (''Solenopsis invicta''), also known as the fire ant or RIFA, is a species of ant native to South America. A member of the genus '' Solenopsis'' in the subfamily Myrmicinae, it was described by Swiss entomologist Felix Santschi as a variant of '' S. saevissima'' in 1916. Its current specific name ''invicta'' was given to the ant in 1972 as a separate species. However, the variant and species were the same ant, and the name was preserved due to its wide use. Though South American in origin, the red imported fire ant has been accidentally introduced in Australia, New Zealand, several Asian and Caribbean countries, and the United States. The red imported fire ant is polymorphic, as workers appear in different shapes and sizes. The ant's colours are red and somewhat yellowish with a brown or black gaster, but males are completely black. Red imported fire ants are dominant in altered areas and live in a wide variety of habitats. They can be found in rain f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Ant
Fire ants are several species of ants in the genus ''Solenopsis'', which includes over 200 species. ''Solenopsis'' are stinging ants, and most of their common names reflect this, for example, ginger ants and tropical fire ants. Many of the names shared by this genus are often used interchangeably to refer to other species of ant, such as the term red ant, mostly because of their similar coloration despite not being in the genus Solenopsis. Both '' Myrmica rubra'' and '' Pogonomyrmex barbatus'' are common examples of non-Solenopsis ants being termed red ants. None of these names apply to all species of ''Solenopsis'' nor only to ''Solenopsis'' species; for example the colloquial names for several species of weaver ants in the genus '' Oecophylla'' in Southeast Asia include "fire ants" because of their similar coloration and painful bites; the two genera, however, are not closely related. '' Wasmannia auropunctata'' is another unrelated ant commonly called the "little fire ant" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
