A study just published instresses that conservation efforts targeting other animals “hairy or feathered” also benefit and these “deserve the same attention”emphasizes Bruce Young, NGO leader NatureServ and co-author of the article.
“These are charming creatures that play an indispensable role inplanets”predators pests or prey for birds and other animals, insists his colleague Sean O’Brien, president NatureServquoted in the press release.
Reptiles are more threatened than birds
Published study is an overall assessment of extinction riskcompleted on “more than 15 years” and signed by some fifty authors, while collecting information with the support of hundreds of scientists from six continents, the three editors explained during a press conference.
“Endangered” species are classified into three categories: “Vulnerable”, “Endangered” or “Critically Endangered” according to the classification of the Red ListThe International Union for Conservation of Nature is one of the leading public organizations in this field.
The study shows thatproportionately less threatened globally than or amphibians, but more so than birds.
Some regions are more open: Southeast Asia, West Africa, northern Madagascar, northern Andes, Caribbean. And reptiles living in forests are the most threatened: 30% of them versus 14% of those living in arid environments.
“Habitat loss (…) continues to be a major threat”, notes Neil Cox of the IUCN. Of all the species studied, the mostand even more concerned are the crocodiles, victims of overexploitation and persecution. A source of food and victims of beliefs associated with their healing properties, they are also captured to become pets for the former. But they also hunted for their danger to the latter.
Another example is the king cobra, an iconic animal found widely in India and Southeast Asia. “It was supposed to be in decline, now it is classified as vulnerable”Neil Cox notes. He is punished by the disappearance of the forest in which he lives, in connection with the exploitation of forests or their transformation intoagricultural.
Billions of cumulative years of evolution
Relativelyhe could directly threaten “10 or 11% reptiles”considers Bruce Young, even if this figure is likely an underestimate by the study, in part because the negative impact will be observed in the longer term, while the IUCN red list criteria are associated with more immediate effects, spanning the next three generations. species or a decade, whichever is longer.
For his part, Professor Blair Hedges, an expert onto Temple University (USA), warns against memory loss from these animals. “Sixteen billion years of evolution will be lost if all endangered species die out”he warns. Among them are Galapagos sailor, “the only lizard in the world that has adapted to aquatic life”he recalls.
Measurements» urgently and purposefully necessary to protect the most endangered species, the authors of the study argue, “especially those lizards endemic to the islands threatened by introduced predators and those more directly affected by humans”.
Nearly 19% of reptiles are endangered
Article by Delphine Bossi, published February 20, 2013
Are reptiles endangered? A major international study estimates that 19% of the world’s species are threatened with extinction, according to the IUCN Conservation Status.
Evolutionit’s a long story. Appearing on Earth 300 million years ago, they eventually became key elements ground. Some reptiles are prey, others are predators. They are usually associated with extreme living conditions or hostile environments.
However, mostspecially adapted to their environment. They require special climatic conditions and their daily good health depends on the use of their habitat. Therefore, reptiles are very sensitive to environmental changes. or the conversion of habitats to areas of cultivation completely threaten these species.
More than 200 specialists coordinated Zoological Society of London andassessed the conservation status of all reptiles worldwide. Such synthesizing work is carried out for the first time. Published in a magazine , the study states that 19% of reptiles are endangered. The study includes an analysis of 1,500 species from around the world. Of the endangered species, 12% are considered endangered, 41% endangered and 47% vulnerable.
Endangered freshwater turtles
are those that have the highest level of threat. in forests are increasingly being transformed for or . The habitat of the lizard is practically destroyed, so the search for the species in some areas has not been successful. In addition, three species classified as endangered may have become extinct. One of the three is a lizard Ameiva vittataseen only once in part of Bolivia.
But the risk of extinction is unevenly distributed across a large group of reptiles. turtlesare in the greatest danger. According to the study, 30% close to extinction. The rate increases to 50% if only turtles are counted. In addition to destroying their habitat, they are poached for the shell trade.
The man is still in question
Terrestrial reptiles are less dangerous. However, their biological and ecological needs, as well as their low mobility, make them particularly vulnerable toHuman. Six out of nine in Haiti Anolis included in this study pose a high risk of extinction due to the massive deforestation that is affecting the country.
The findings of this study are troubling because they are global. The study is a good indicator for assessing conservation success, tracking trends in extinction risk over time, and humanity’s ability to implement biodiversity conservation plans.
