Ecuadorian White-fronted Capuchin
The Ecuadorian capuchin (''Cebus aequatorialis''), or Ecuadorian white-fronted capuchin is a species of gracile capuchin monkey of the family Cebidae. It was formerly classified as a subspecies of the white-fronted capuchin (''C. albifrons''). Russell Mittermeier, Mittermeier and Rylands elevated it to a separate species in 2013. The primary physical distinction between ''C. albifrons'' and ''C. aequatorialis'' is their coloration. Due to low density and distribution researchers have not been able to make a confident molecular genetic assessment of the ''C. aequatorialis'' population, but assign it species status based on geographical isolation, morphological characteristics, and the phylogenetic species concept. The location range of the Ecuadorian Capuchin is from Western lowland Ecuador to North West Peru. The conservation status of the Ecuadorian Capuchin was originally near threatened but was revised in 2008 by the International Union for Conservation of Nature, IUCN to ...

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] |
Bromeliaceae
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumbes, Peru
Tumbes is a city in northwestern Peru, on the banks of the Tumbes River. It is the capital of the Tumbes Region, as well as of Tumbes Province and Tumbes District. Located near the border with Ecuador, Tumbes has 111,595 inhabitants as of 2015. It is served by the Cap. FAP Pedro Canga Rodriguez Airport. It is located on the Gulf of Guayaquil along with Zorritos. History Tumbes has its origins back in pre-Inca times when it was inhabited by a cultural group of natives called Tumpis. At its peak, its population is estimated to have reached 178,000. After 1400, Inca Pachacuti ruled over Tumbes and the territory became an important political stronghold during the Inca Empire. Later Inca emperor Huayna Capac expanded Tumbes by ordering the construction of roads, houses and palaces. Spanish arrival Tumbes was first visited by Spanish conquistador Francisco Pizarro during the start of the Spanish conquest of the Inca Empire in 1528.Prescott, W.H., 2011, The History of the Conquest ...

Andes
The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the List of longest mountain chains on Earth, longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long and wide (widest between 18th parallel south, 18°S and 20th parallel south, 20°S latitude) and has an average height of about . The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela. Along their length, the Andes are split into several ranges, separated by intermediate depression (geology), depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, Mérida, Mérida, El Alto, and La Paz. The Altiplano, Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three majo ...

Guayaquil
Guayaquil (), officially Santiago de Guayaquil, is the largest city in Ecuador and also the nation's economic capital and main port. The city is the capital (political), capital of Guayas Province and the seat of Guayaquil Canton. The city is located on the west bank of the Guayas River, which flows into the Pacific Ocean at the Gulf of Guayaquil. With a population of 2,746,403 inhabitants, it is the most populous city in the country, and the fifth largest in the Andean Community. However, its urban fabric extends beyond its official urban parishes, encompassing nearby cities and parishes; thus, the Guayaquil metropolitan area reaches a population of 3,618,450, making it the most populous urban agglomeration in the nation, and also the fifth in the Andean Community. As the largest city, it is one of the two main development poles of the country—alongside Quito, the national capital—hosting Ecuador’s main business, financial, cultural, and sports institutions.

Tropical And Subtropical Dry Broadleaf Forests
The tropical and subtropical dry broadleaf forest is a habitat (ecology), 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 millimeters 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 (forest), 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 ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene Flow
In population genetics, gene flow (also known as migration and allele flow) is the transfer of genetic variation, genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population. It has been shown that it takes only "one migrant per generation" to prevent populations from diverging due to Genetic drift, drift. Populations can diverge due to Natural selection, selection even when they are exchanging alleles, if the selection pressure is strong enough. Gene flow is an important mechanism for transferring genetic diversity among populations. Migrants change the distribution of genetic diversity among populations, by modifying allele frequencies (the proportion of members carrying a particular variant of a gene). High rates of gene flow can reduce the genetic differentiation between the two groups, increasing homogeneity. Gene flow has b ...

Mining
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.

Grazing
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to feed conversion ratio, convert the otherwise indigestible (by human digestive system, human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming. Farmers may employ many different strategies of grazing for crop yield, optimum production: grazing may be continuous, seasonal, or rotational grazing, rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site. Grazing has existed ...
