Deppe's Squirrel
Deppe's squirrel (''Sciurus deppei'') is a species of tree squirrel in the genus ''Sciurus'' native to Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. Description ''Sciurus deppei'' varies in individual color. The overall color of the body is gray to yellowish brown or rusty-colored brown, while the face is gray. The legs are dark gray or rust colored. The top of the tail is black with a few white hairs mixed in while the bottom side of the tail is yellowish orange to a rust color, the hairs on the tip of the tail are white. Changes in their fur due to seasons aren't typically seen, except for the white tip on their tail and the patches of hair behind the ears disappear during the summer season. Size varies a little bit in the Deppe's squirrel with the average female being around 287.3 g, HB 210.2 mm, and T 169.4 mm. The males average is 268.3 g, HB 207.2 mm, and T 176.0 mm. Both sexes are close in size, but the females tend t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 in Koldenbüttel – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he g ...

Mammals Described In 1863
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, pinniped, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with S ...

Rodents Of Central America
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose incisors ...

Richmond's Squirrel
Richmond's squirrel (''Sciurus richmondi'') is a poorly known tree squirrel in the genus ''Sciurus'' endemic to Nicaragua, which is likely a synonym of the red-tailed squirrel (''Sciurus granatensis''). It is locally known as the ardilla del rama. Taxonomy It was first described in 1898 by Nelson based on a series of specimens collected in 1892. Specimens were collected again in 1908 and 1910 by Joel Asaph Allen. No more specimens were then collected until 53 were taken in the 1960s. It appears no scientific specimens were taken or official observations recorded after the 1960s of which data has been uploaded to the GBIF. Description Very similar to the ''Sciurus granatensis'' ssp. ''hoffmanni'', but smaller in size, coloured less brightly, and with lighter coloured hairs on the tail. It has a brown back and tail, the tail streaked with tawny yellowish hairs, and an orange abdomen. Females have noticeably wider cheekbones than the males, but are otherwise morphologically identi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andean Squirrel
The Andean squirrel (''Sciurus pucheranii'') is a tree squirrel endemic to Colombia where it inhabits montane rain forest and cloud forests of the Cordillera Occidental and Cordillera Central ranges of the Colombian Andes, at elevations between . It is a small species with a body length of about and a similar length tail. It has soft, silky, reddish-brown fur, a darker tail and yellowish-grey underparts. It is thought to be diurnal but has been little studied, and the International Union for Conservation of Nature has rated its conservation status as being data deficient. Description The Andean squirrel is a typical tree squirrel, in its general proportions resembling the Eastern grey squirrel of North America. However, it is much smaller, with a body length of only about , and a tail. Although there are few records of its weight, it appears to be generally between about . It has soft, silky, reddish-brown fur over most of the body, merging to greyish-yellow on the underpar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The red-tailed squirrel (''Sciurus granatensis'') is a species of tree squirrel distributed from southern Central America to northern South America. Distribution It is found in Central and South America ( Colombia, Costa Rica, Ecuador, Panama, and Venezuela) and the Caribbean islands of Trinidad and Tobago and Margarita.

Maya Civilization
The Maya civilization () of the Mesoamerican people is known by its ancient temples and glyphs. Its Maya script is the most sophisticated and highly developed writing system in the pre-Columbian Americas. It is also noted for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in the Maya Region, an area that today comprises southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. It includes the northern lowlands of the Yucatán Peninsula and the highlands of the Sierra Madre, the Mexican state of Chiapas, southern Guatemala, El Salvador, and the southern lowlands of the Pacific littoral plain. Today, their descendants, known collectively as the Maya, number well over 6 million individuals, speak more than twenty-eight surviving Mayan languages, and reside in nearly the same area as their ancestors. The Archaic period, before 2000 BC, saw the first developments in agricul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tikal National Park
Tikal National Park is a national park located in Guatemala, in the northern region of the Petén Department. Stretching across 57,600 hectares, it contains the ancient Mayan city of Tikal and the surrounding tropical forests, savannas, and wetlands. In 1979, Tikal National Park was declared as a World Heritage Site by UNESCO, because of the outstanding Mesoamerican ruins at Tikal and the unique ecology of the surrounding landscape. History "Project Tikal", as it was named at the time, was first proposed by the University of Pennsylvania in 1949. Founded on May 26, 1955, Tikal National Park was established under government decree by the Ministry of Education, via the Instituto de Antropología e Historia, advised by Dr. Adolfo Molina Orantes and under the government of Carlos Castillo Armas. Once established, the University of Pennsylvania played a role in the park's cleaning, maintenance, excavation and restoration of the site from 1956 to 1969. Today, Tikal National Park's mai ...
