Robert Kerr (writer)
Dr Robert Kerr FRSE FAS FRCSE (20 October 1757 – 11 October 1813) was a Scottish surgeon, writer on scientific and other subjects, and translator. Life Kerr was born in 1757 in Bughtridge, Roxburghshire, the son of James Kerr, a jeweller, who served as MP for Edinburgh 1747–1754, and his wife Elizabeth. He was sent to the High School in Edinburgh. He studied medicine at the University of Edinburgh and practised at the Edinburgh Foundling Hospital as a surgeon. He was elected a Fellow of the Royal Society of Edinburgh in 1788. His proposers were Alexander Fraser Tytler, James Russell and Andrew Dalzell. At this time he lived at Foresters Wynd off the Royal Mile in Edinburgh. He translated several scientific works into English, such as Antoine Lavoisier's work of 1789, ''Traité Élémentaire de Chimie'', published under the title ''Elements of Chemistry in a New Systematic Order containing All the Modern Discoveries'', in 1790. In 1792, he published ''The Animal Kingdom' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Of Mexico
This is a list of the native wild mammal species recorded in Mexico. As of September 2014, there were 536 mammalian species or subspecies listed. Based on International Union for Conservation of Nature, IUCN data, Mexico has 23% more noncetacean mammal species than the U.S. and Canada combined in an area only 10% as large, or a species density over 12 times that of its northern neighbors. Mexico's high mammal biodiversity is in part a reflection of the wide array of biomes present over its latitudinal, climatic and altitudinal ranges, from lowland tropical rainforest to temperate desert to montane forest to alpine tundra. The general increase in terrestrial biodiversity moving towards the equator is another important factor in the comparison. Mexico includes much of the Mesoamerica#Biodiversity, Mesoamerican and Madrean pine-oak woodlands biodiversity hotspots. From a biogeographic standpoint, most of Mexico is linked to the rest of North America as part of the Nearctic realm. Howeve ...

Mammals Of Central America
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, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...

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 ...

Brosimum
''Brosimum'' is a genus of plants in the family Moraceae, native to tropical regions of the Americas. The breadnut ('' B. alicastrum'') was used by the Maya civilization for its edible nut. The dense vividly colored scarlet wood of '' B. paraense'' is used for decorative woodworking.Baker (2004) '' B. guianense'', or snakewood, has a mottled snake-skin pattern, and is among the densest woods, with a very high stiffness; it was the wood of choice for making of bows for musical instruments of the violin family until the late 18th century, when it was replaced by the more easily worked brazilwood ('' Paubrasilia echinata''). Plants of this genus are otherwise used for timber, building materials, and in a cultural context.

Ficus
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergreen, bu ...

Cecropia
''Cecropia'' is a Neotropical genus consisting of 61 recognized species with a highly distinctive lineage of dioecious trees. The genus consists of pioneer trees in the more or less humid parts of the Neotropics, with the majority of the species being myrmecophytic.Berg, Rosselli & Davidson (2005) Berg and Rosselli state that the genus is characterized by some unusual traits: spathes fully enclosing the flower-bearing parts of the inflorescences until anthesis, patches of dense indumentums (trichilia) producing Mullerian (food) at the base of the petiole, and anthers becoming detached at anthesis. ''Cecropia'' is most studied for its ecological role and association with ants. Its classification is controversial; in the past, it has been placed in the Cecropiaceae, Moraceae (the mulberry family), or Urticaceae (the nettle family).Burger (1977) The modern Angiosperm Phylogeny Group system places the "cecropiacean" group in the Urticaceae. The genus is native to the American tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inga
''Inga'' is a genus of small tropical, tough-leaved, nitrogen-fixing treesElkan, Daniel. "Slash-and-burn farming has become a major threat to the world's rainforest" ''The Guardian'' 21 April 2004 and shrubs, subfamily Mimosoideae. ''Inga''s leaves are pinnate, and flowers are generally white. Many of the hundreds of species are used ornamentally. Several related plants have been placed into this genus at one time, for example Yopo (Cohoba, Mopo, Nopo or Parica – '' Anadenanthera peregrina'' – as ''Inga niopo''). The seeds are covered with sweet white powder. The pulp covering the seeds is lightly fibrous and sweet, and rich in minerals; it is edible in the raw state. The tree's name originates from the Tupi word ''in-gá'' meaning "soaked", due to the fruit powder consistency. The tree usually blooms twice a year. Within the ''Inga'' genus there are around 300 species, most of them native and growing in the Amazon forest region although some species are also found in M ...

Prehensile Tail
A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees. If the tail cannot be used for this it is considered only partially prehensile - such tails are often used to anchor an animal's body to dangle from a branch, or as an aid for climbing. The term ''prehensile'' means "able to grasp" (from the Latin ''prehendere'', to take hold of, to grasp). Evolution One point of interest is the distribution of animals with prehensile tails. The prehensile tail is predominantly a New World adaptation, especially among mammals. Many more animals in South America have prehensile tails than in Africa and Southeast Asia. It has been argued that animals with prehensile tails are more common in South America because the forest there is denser than in Africa or Southeast Asia. In contrast, less dense forests such as in S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rothschild's Porcupine
The Andean porcupine (''Coendou quichua'') or Quichua porcupine is a species of rodent in the family Erethizontidae. It is found in the Andes of northern Ecuador and Colombia as well as in Panama. This porcupine is little known, but is probably arboreal, nocturnal and solitary like its relatives. The species is thought to be uncommon to rare and the population decreasing. It is threatened by deforestation, habitat fragmentation and agriculture. Taxonomy Although it is morphologically distinctive, it has sometimes been described as a subspecies of the bicolored-spined porcupine (''C. bicolor''). However, genetic studies have shown it to be closest to the stump-tailed porcupine (''C. rufescens''). Rothschild's porcupine (''C. rothschildi'') of Panama was formerly considered a distinct species, but phylogenetic evidence indicates that both are synonymous. Description The Andean porcupine is a medium-sized porcupine with a head-and-body length of between and a tail length of b ...
