Yucatan Squirrel
The Yucatan squirrel (, ''Sciurus yucatanensis''), originally named the Yucatan gray squirrel, also once named the Campeche squirrel, is a tree squirrel in the genus ''Sciurus'' found in the Yucatán Peninsula and adjacent areas. It is native to northern Belize, northeastern Guatemala, and southeast Mexico. Biology The Yucatan squirrel lives in dry deciduous and evergreen forests, semiarid pine-oak woodlands, and secondary forest growing in formerly logged areas. They are found in lowlands below an altitude of . They are active during the day and rest during the night, spending most of their time in trees. They are most active in the early morning, but may be seen sunning on a branch later in the day. Their dreys (or nests), to be found in branches high up in the trees, are built from leaves and twigs. Their food consists of soft fruit, nuts and seeds, whilst Reid in 2009 concluded that their main diet consists of flowers, buds, and shoots. Females generally give birth to two ...

Joel Asaph Allen
Joel Asaph Allen (July 19, 1838 – August 29, 1921) was an American zoology, zoologist, mammalogy, mammalogist, and ornithology, ornithologist. He became the first president of the American Ornithologists' Union, the first curator of birds and mammals at the American Museum of Natural History, and the first head of that museum's Department of Ornithology. He is remembered for Allen's rule, which states that the bodies of endotherms (warm-blooded animals) vary in shape with climate, having increased surface area in hot climates to lose heat, and minimized surface area in cold climates, to conserve heat. Early life Allen was born in Springfield, Massachusetts, the son of Joel Allen and Harriet Trumbull. He studied and collected specimen of natural history early in life, but he was forced to sell his relatively large collection so that he could attend the Wilbraham & Monson Academy in 1861. The following year, he transferred to Harvard University, where he studied under Louis Agassi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collie's Squirrel
Collie's squirrel (''Sciurus colliaei'') is a tree squirrel in the genus ''Sciurus'' endemic 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 else ... to Mexico. Distribution The Collie's squirrel is native to the western coast of Mexico, including the states of Sonora, Chihuahua, Sinaloa, Durango, Nayarit, Jalisco, and Colima.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alta Verapaz Department
Alta Verapaz () is a department in the north central part of Guatemala. The capital and chief city of the department is Cobán. Verapaz is bordered to the north by El Petén, to the east by Izabal, to the south by Zacapa, El Progreso, and Baja Verapaz, and to the west by El Quiché. Also in Alta Verapaz are the towns of Chisec, San Pedro Carchá and San Cristóbal Verapaz. History In Pre-Columbian times this area was part of the Maya civilization. When the Spanish Conquistadores came in the 1520s they conquered the central and southern highlands of Guatemala, but were driven back from this region by fierce native resistance. Unknown to the history books of this region, local oral history speaks of a former slave ship capsizing prior to the Spaniards arriving upon this area of Guatemala. The former African slaves moved inland, and joined forces with the local indigenous people to fight and maintain their freedom. Spanish friars succeeded in converting the area to Chri ...

Campeche
Campeche (; yua, Kaampech ), officially the Free and Sovereign State of Campeche ( es, Estado Libre y Soberano de Campeche), is one of the 31 states which make up the 32 Federal Entities of Mexico. Located in southeast Mexico, it is bordered by the states of Tabasco to the southwest, Yucatán to the northeast, and Quintana Roo to the east; to the southeast by the Orange Walk district of Belize, and by the Petén department of Guatemala to the south. It has a coastline to the west with the Gulf of Mexico. The state capital, also called Campeche, was declared a World Heritage Site in 1997. The formation of the state began with the city, which was founded in 1540 as the Spanish began the conquest of the Yucatán Peninsula. The city was a rich and important port during the colonial period, but it declined after Mexico's independence. Campeche was part of the province of Yucatán but split off in the mid-19th century, mostly due to political friction with the city of Mérida. Much ...

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. In 1871, his large insect collection was lost in the Chicago Fire and the family was left homeless. This was the time that h ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Carl Victor Schott
Arthur Carl Victor Schott (27 February 1814 – 26 July 1875) was a German-American artist, naturalist and ethnographer. He was hired as a "special scientific collector" for the United States Boundary Commission, and participated in their survey of the new border between the United States and Mexico established after the Mexican–American War. Personal background Schott was born on 27 February 1814, in Stuttgart, Germany. He was the son of Christian Friedrich Albert Schott. Having finished at a ''Gymnasium'' (high school) and technical school in Stuttgart, Schott worked for a year as apprentice at the Royal Gardens in Stuttgart, after which he enrolled at the Institute of Agriculture at Hohenheim. Professional background After the U.S.-Mexican War in which Mexico had to cede almost half of its territory, now comprising much of the American Southwest, it became necessary to survey and map the new, nearly of border between the two countries. In 1851, Schott was appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mérida, Yucatán
Mérida () is the capital of the Mexican state of Yucatán, and the largest city in southeastern Mexico. The city is also the seat of the eponymous Municipality. It is located in the northwest corner of the Yucatán Peninsula, about 35 km (22 mi) inland from the coast of the Gulf of Mexico. In 2020 it had a population of 921,770 while its metropolitan area, which also includes the cities of Kanasín and Umán, had a population of 1,316,090. The city's rich cultural heritage is a product of the syncretism of the Maya and Spanish cultures during the colonial era. It was the first city to be ever named American Capital of Culture and is the only city that has received the title twice. The Cathedral of Mérida, Yucatán was built in the late 16th century with stones from nearby Mayan ruins and is known to be the oldest cathedral in the mainland Americas. In addition, the city has the third largest old town district on the continent. In 2007, the city was visited by former U.S ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
