Volcano Rabbit
The volcano rabbit (''Romerolagus diazi'') (), also known as the teporingo or zacatuche, is a small mammal in the family Leporidae that resides on the slopes of volcanoes in Mexico. It is the only species in the genus ''Romerolagus''. It has small rounded ears, short legs, a large forehead, and short, thick fur. Adult rabbits can weigh from . The volcano rabbit lives in groups of 2 to 5 animals in burrows (underground nests) and runways among bunchgrasses. Up to 3 young are produced per litter, born in nests formed from shallow depressions in the ground lined with fur and plant matter. Uniquely among the rabbits, the volcano rabbit emits high-pitched sounds to warn other rabbits of danger, a habit common in the related pikas. It is awake and most active in the evening and early morning. Populations have been estimated as approximately 7,000 adult individuals over their entire range. Human developments surrounding the volcano rabbit's habitat, including overgrazing, hunting, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priabonian
The Priabonian is, in the ICS's geologic timescale, the latest age or the upper stage of the Eocene Epoch or Series. It spans the time between . The Priabonian is preceded by the Bartonian and is followed by the Rupelian, the lowest stage of the Oligocene. '' Priabona'', an extinct dipteran of Pipunculidae family, is named after Priabonian, the age of deposits from which this insect is known. History and naming The Priabonian Stage was introduced in scientific literature by Ernest Munier-Chalmas and Albert de Lapparent in 1893. The stage is named after the small hamlet of Priabona in the community of Monte di Malo, in the Veneto region of northern Italy. Stratigraphic definition The base of the Priabonian Stage is at the first appearance of calcareous nannoplankton species '' Chiasmolithus oamaruensis'' (which forms the base of nanoplankton biozone NP18). An official GSSP was ratified in 2020, and was placed in the Alano di Piave section in Alano di Piave, Bellu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Locomotion In Mammals
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Edward William Nelson
Edward William Nelson (May 8, 1855 – May 19, 1934) was an American naturalist and ethnologist. A collector of specimens and field naturalist of repute, he became a member of several expeditions to survey the fauna and flora. He was part of a team with Clinton Hart Merriam that took part in the Death Valley Expedition. He also explored the Yosemite Valley. A number of vertebrate species are named after him. Biography Nelson was born in Manchester, New Hampshire, on May 8, 1855, the first son of William and Martha () Nelson. Nelson and his brother then lived with his maternal grandparents in the Adirondacks when his father joined the Union Army and mother went to Baltimore as a nurse. Here he fell in love with the wilderness. Nelson moved to Chicago after his father was killed in the Civil War and his mother established a dressmaking business.

Popocatépetl
Popocatépetl ( , , ; ) is an active stratovolcano located in the states of Puebla, Morelos, and Mexico in central Mexico. It lies in the eastern half of the Trans-Mexican Volcanic Belt. At it is the second highest peak in Mexico, after Citlaltépetl (Pico de Orizaba) at . Popocatépetl is ranked 89th by prominence. It is linked to the twin volcano of Iztaccihuatl to the north by the high saddle known as the " Paso de Cortés". Izta-Popo Zoquiapan National Park, wherein the two volcanoes are located, is named after them. Popocatépetl is southeast of Mexico City, from where it can be seen regularly, depending on atmospheric conditions. Until recently, the volcano was one of three tall peaks in Mexico to contain glaciers, the others being Iztaccihuatl and Pico de Orizaba. In the 1990s, the glaciers such as Glaciar Norte (North Glacier) greatly decreased in size, partly due to warmer temperatures but largely due to increased volcanic activity. By early 2001, Popocatép ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iztaccihuatl
Iztaccíhuatl or Ixtaccíhuatl (both forms also spelled without the accent) ( or, as spelled with the x, ) is a dormant volcanic mountain in Mexico located on the border between the State of Mexico and Puebla within Izta-Popo Zoquiapan National Park. It is the nation's third highest, after Pico de Orizaba at , and Popocatépetl at . The name "Iztaccíhuatl" is Nahuatl for "White (like salt) woman", reflecting the four individual snow-capped peaks which depict the head, chest, knees and feet of a sleeping female when seen from east or west. Iztaccíhuatl is to the north of its twin Popocatépetl, to which it is connected by the high altitude Paso de Cortés. Depending on atmospheric conditions Iztaccíhuatl is visible much of the year from Mexico City some to the northwest. The first recorded ascent was made in 1889, though archaeological evidence suggests the Mexica and previous cultures climbed it previously. It is the lowest peak containing permanent snow and glaciers in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Cartographer
Cartography (; from , 'papyrus, sheet of paper, map'; and , 'write') is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate the mapped object's characteristics that are irrelevant to the map's purpose. This is the concern of Cartographic generalization, generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
