The Jaguar in greater risk of extinction than formally thought
AT Xamach, our home for twenty years, we use to find their paw prints in the wet sand near the beach.
Mexico (Notimex) .- Researchers at the Institute of Ecology (IE) of the National Autonomous University of Mexico (UNAM) reported that the jaguar (panthera onca) is at greater risk of extinction than previously thought.
After studying, experts concluded that on the planet there are almost 64,000 jaguars and 34 subpopulations, from northern Mexico to Argentina, but 33 are at risk or critical danger of disappearing.
According to the research, of the total specimens, 90 percent (57 thousand) are located in the subpopulation of the Amazon, which covers regions of Brazil, Peru, Ecuador and Colombia, and is the only one that, because of its size, does not Is considered at risk.
The remaining subpopulations, he said, contain 10 percent of the copies (seven thousand) and in Mexico, according to this estimate, there are less than four thousand.
The results of the joint work of the Ecology and Conservation of Terrestrial and Wildlife Faunal Laboratories of IE, by Rodrigo Medellín and Gerardo Ceballos, respectively, were published in the most recent issue of the journal "Oryx. The International Journal of Conservation ".
In a statement, the maximum house of studies reported that this article coincides with the publication of the book "The jaguar in the 21st century: the continental perspective," also coordinated by scientists and their colleagues, but with the participation of 50 authors of 12 Countries.
The researchers found that with the detection of small, isolated subpopulations with poor protection or densities of very high human populations, and by specifying the vulnerability of each of them, it will be possible to determine the conservation priorities for this iconic species.
They propose to the International Union for Conservation of Nature (IUCN), which publishes the Red List used throughout the world as a guide for conservation policies and practices, not to assess the species by the total population, but by the situation Of each of its subpopulations.
They indicated that the distribution of the jaguar declined by more than 40 percent in Mexico and is limited in the most isolated and inaccessible areas, such as in the Pacific and Gulf coasts, the Western and Eastern Sierras and the south-southeast from the country.
Ceballos explained that the best preserved populations are on the Yucatan peninsula, Oaxaca and Chiapas, with at least 1,800 copies, while in Sonora and Sinaloa there could be 400; 300 in the middle Pacific coast, in Nayarit, Jalisco and Colima, and 650 in Michoacan to Chiapas.
He stressed the urgency of articulating efforts in a correct way to save not only this species but also the forests and forests that hold almost 45 percent of the country's biological diversity.
The permanence of the jaguar in our territory is a coin in the air and not having a strong and established conservation policy, "will fall in the next 10 or 15 years," Medellín concluded.
