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] |
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 ...

Lake Nicaragua
Lake Nicaragua or Cocibolca or Granada ( es, Lago de Nicaragua, , or ) is a freshwater lake in Nicaragua. Of tectonic origin and with an area of , it is the largest lake in Central America, the 19th largest lake in the world (by area) and the tenth largest in the Americas, slightly smaller than Lake Titicaca. With an elevation of above sea level, the lake reaches a depth of . It is intermittently joined by the Tipitapa River to Lake Managua. The lake drains to the Caribbean Sea via the San Juan River, historically making the lakeside city of Granada an Atlantic port, although Granada (as well as the entire lake) is closer to the Pacific Ocean geographically. The Pacific is near enough to be seen from the mountains of Ometepe (an island in the lake). The lake has a history of Caribbean pirates who assaulted Granada on three occasions. Before construction of the Panama Canal, a stagecoach line owned by Cornelius Vanderbilt's Accessory Transit Company connected the lake with t ...

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 ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Tropical And Subtropical Dry Broadleaf Forests
The tropical and subtropical dry broadleaf forest is a habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Juan River (Nicaragua)
The San Juan River (Spanish: ''Río San Juan''), also known as El Desaguadero ("the drain"), is a river that flows east out of Lake Nicaragua into the Caribbean Sea. A large section of the border between Nicaragua and Costa Rica runs on the southern bank of the river. It was part, with the lake, of a proposed route for a Nicaragua Canal in the 19th century. The idea of the project has been revived in the last decade, including the possibility of other routes within the country. The Ecocanal project has obtained a Concession from the National Assembly of Nicaragua to re-open the San Juan River to commercial barge traffic. The Cañas–Jerez Treaty states that Nicaragua owns the waters of the river and that Costa Rica can only use it for commercial navigation on certain parts of the river at Nicaragua's discretion. The San Juan River is home to freshwater bull sharks that also go into Lake Nicaragua in addition to a wide array of marine life and biodiversity. History Before th ...

Tree Squirrel
Tree squirrels are the members of the squirrel family (Sciuridae) commonly just referred to as "squirrels." They include more than 100 arboreal species native to all continents except Antarctica and Oceania. They do not form a single natural, or monophyletic, group; they are variously related to others in the squirrel family, including ground squirrels, flying squirrels, marmots, and chipmunks. The defining characteristic used to determine which species of Sciuridae are tree squirrels is dependent on their habitat rather than their physiology. Tree squirrels live mostly among trees, as opposed to those that live in burrows in the ground or among rocks. An exception is the flying squirrel that also makes its home in trees, but has a physiological distinction separating it from its tree squirrel cousins: special flaps of skin called patagia, acting as glider wings, which allow gliding flight. The best known genus of tree squirrels is '' Sciurus'', which includes the eastern g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honduras
Honduras, officially the Republic of Honduras, is a country in Central America. The republic of Honduras is bordered to the west by Guatemala, to the southwest by El Salvador, to the southeast by Nicaragua, to the south by the Pacific Ocean at the Gulf of Fonseca, and to the north by the Gulf of Honduras, a large inlet of the Caribbean Sea. Its capital and largest city is Tegucigalpa. Honduras was home to several important Mesoamerican cultures, most notably the Maya, before the Spanish Colonization in the sixteenth century. The Spanish introduced Catholicism and the now predominant Spanish language, along with numerous customs that have blended with the indigenous culture. Honduras became independent in 1821 and has since been a republic, although it has consistently endured much social strife and political instability, and remains one of the poorest countries in the Western Hemisphere. In 1960, the northern part of what was the Mosquito Coast was transferred from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-tailed Squirrel
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. According to the Global Register of Introduced and Invasive Species it has also been introduced and is invasive in Cuba, however this refers to a small population found around some parts of the margin of Rio Almendares in Havana, which escaped from the Havana Zoo. Habitat Ranges from in elevation. It inhabits many types of forests, and can be found in picnic grounds. Taxonomy It was recently reclassified as ''Notosciurus granatensis'' in 2015, ''Notosciurus'' being a genus created in 1914 by Joel Asaph Allen for a juvenile of this species. however, the IUCN still puts it as a member of the genus ''Sciurus''.
