Finding in Ecuador a new species of mono leoncillo, the most beautiful primate of the world | Ecology | La Revista

Scientists lograron confirm the existence of a new species of mono leoncillo in the Ecuadorian Amazon, donde is created just now that one exists, informs the University of San Francisco de Quito (USFQ).

The studio has been unrolled since 2015 by the Chair and Investigator of the College of Biological and Ambient Sciences (COCIBA) of the USFQ, Stella de la Torre, in collaboration with primatologists from the Universities of the United States, Northern Illinois and Michigan-Ann Arbor, and the Institute of Investigations of the Peruvian Amazon.

Investigators analyze information that permits determine the existence of two species of leoncillos in Ecuador. The Napo River separates these species in our country. In the north of the Ecuadorian Amazon is the species Cebuella pygmaea, mientras que en el sur habita la Cebuella niveiventris.

These species are in great demand for their high quality diet and diet, They live solely in the forests of galleries, in the gorges and lagoons of the Amazon and feed exclusively on the exudes of a few plant species. The deforestation of its habitats, its illegal capture for the mascot market, as well as its epidemics, are its main concerns.

The European naturalist Johann Baptist Von Spix describes por primera vez en 1823 al mono leoncillo, based on a specimen captured in a locality of the Amazonian Highlands of Brazil. Since this year 2018, all the populations of monocles in Brazil, Bolivia, Colombia, Peru and Ecuador are considered as populations of a single species (Cebuella pygmaea). This year, a group of Brazilian scientists carried out a genetic analysis and described the species of these primates in Brazil, but in the rest of the country, including Ecuador, it seems that it has a single species.

Al vergling met ADN mitochondrial extraction of heces samples from distinct localities in Ecuador, and tejido samples from specimens from museums in our country and Peru, the investigators read the conclusion that there are species that in biology are known as “cryptic species”, so there are many similar species in their physical characteristics such as the color of their skin, but which differ in their DNA.

What are the characteristics of this species?

The leoncillos are considered the most beautiful primates of the world. In adults, the length of the head and the body together increase by 12 to 16 centimeters and, at a weight, from 100 to 140 grams. Viven in familiar groups integrated by a macho and an adult female and in the absence of various editions.

These are their cooperative reproducers, the female pair, in general, gemelos that his cargados and cuidados mainly by the father and the hermanos of burgemeester edad. In cautiverio, the leoncillos can live up to 18 – 19 years; while in the new state it is estimated to live up to 10 – 12 years.

The 2011 edition of ‘Ecuador’s Red Book of Mammoths’ determines that monocots are included in the list of vulnerable species, and, by its protection by the State. Its fishing, catching and trafficking are punishable by a term of 1 to 3 years.

In the third edition of the same book, currently in edition, Cebuella pygmaea, the species north of the Napo River, found in the list of species in peligro, since its habitat is minor and is most affected by human activities, while que Cebuella niveiventris, the species on the Napo, is in the list of kwesbaar species.
