Paris : A recent study warned that rare animals species face the simplest risk from action and also the results of human activities, while they also play a rare but essential environmental role for the ecosystem.
There are quite 4,600 rare animals of land mammals and 9,827 of birds that were counted as “environmentally rare” in an unprecedented study published within the journal Nature Communications on Thursday.
This meticulous work, supported analyzes of giant data at the worldwide level (what is known as “big data”), resulted in an accurate map that mixes the factors of geographical scarcity with “functional scarcity” (a standard adopted for the first time).
This refers to the unique role that some rare animals play within the functioning of the ecosystem, in terms of their characteristics (size, food quality, habitat …). as an example, the indigenous Honduran hummingbird (“Hendrawan Emerald”) is now restricted to four locations within the country. This species contributes to pollination when it feeds on nectar.
The same applies to the black macaques on the Indonesian island of Sulawesi, which were known especially after a selfie taken by one amongst these animals after the camera was aloof from its owner in 2014. These monkeys face the threat of extinction and their diet (which includes over 145 varieties of fruits) is vital. To scatter the seeds of trees.
Nicolas Mouquet, a researcher at the French National Institute for research and a principal participant within the preparation of the study along with his colleague Nicolas Loiseau from the University of Montpellier, told AFP: “Usually, any small sex is perceived to contribute poorly to the functioning of the ecosystem, unlike those that exist in abundance. this will be what we call the number effect. ”
“But really, the functioning of ecosystems is much more complex. It’s kind of a motor, variety of which are rare but necessary to regulate,” added the researcher who runs a middle for analyzes on biodiversity.
In this center locomote Mouquet in Montpellier, France, a worldwide team that features environmental sciences researchers, statisticians and big data experts, analyzed information received from the International Union for Conservation of Nature and from international databases.
The results concluded that mammalian ecological scarcity is concentrated within the tropics and within the hemisphere, with maximum levels within the Indonesian islands, Madagascar and Central American nation. As for birds, their rarity is concentrated in tropical and sub-tropical areas, especially in island and Indonesia, and within the Andes Mountains.
Drawing on climate data models from UN climate experts, the study makes predictions about what the case are visiting be like in 2050 and 2080. “Rare aniamls are visiting be more affected than the common ones,” Nicolas Mouquet said, speaking of “double suffering” as their rare environmental role are going to be lost. Birds are visiting be the foremost affected, and an oversized number of them are in peril of disappearing within forty years.
In addition, rare races are more laid low with human influences altogether countries, regardless of the event index of these countries or the number of conflicts, per the study.
It also occupies an even bigger position on the IUCN Red List of the foremost vulnerable species compared to the common races. However, about 30% weren’t included within the classification “because the standards for measuring the number of risk at the International Union for Conservation of Nature are purely geographical,” in line with the researcher.
The environmental scientist necessitated the international body to feature the role of races to the standards it takes into consideration to measure the degree of danger they face.
The conclusions of the study remain yet within the framework of the statistical hypothesis that needs verification by experiment, per Nicolas Mocket.
“This is also a piece that needs long patience, but environmental emergencies force us to back the necessity to shield these species,” he said.
