Sicilianews24.it: Perdita di prede minaccia l’estinzione dei giaguari della Foresta Atlantica

La Minaccia per i Giaguari nella Foresta Atlantica del Brasile
Nuove ricerche evidenziano una crisi seria per la popolazione di giaguari (Panthera onca) nella Foresta Atlantica del Brasile, dove sta avvenendo un rapido declino a causa della mancanza di prede. I dati suggeriscono che meno di 300 giaguari rimangano in questa area, minacciata dalla caccia illegale e dalla perdita dell’habitat.
La Dispersione delle Prede
La ricerca ha dimostrato che la scomparsa di specie come cervi e peccari, fondamentali per la dieta dei giaguari, è un fattore chiave che contribuisce alla loro estinzione locale. La caccia indiscriminata ha ridotto drammaticamente la popolazione di prede, costringendo i giaguari a competere con gli animali domestici e a ridurre le loro possibilità di sopravvivenza.
“Ci troviamo di fronte a un’estinzione silenziosa delle specie preda nella Foresta Atlantica,” afferma Katia Ferraz, biologa della fauna selvatica presso l’Università di San Paolo. “Parliamo molto di estinzione dei giaguari, ma poco dell’estinzione dei peccari e dei cervi, che sono infrastrutture cruciali per la loro sopravvivenza.”

Loss of prey threatens the extinction of jaguars in the Atlantic Forest.

The Threat to Jaguars in the Atlantic Forest of Brazil
New research highlights a serious crisis for the jaguar (Panthera onca) population in the Atlantic Forest of Brazil, where a rapid decline is occurring due to a lack of prey. The data suggests that less than 300 jaguars remain in this area, threatened by illegal hunting and habitat loss.
The Dispersal of Prey
The research has shown that the disappearance of species such as deer and wild boar, which are essential for the jaguar's diet, is a key factor contributing to their local extinction. Uncontrolled hunting has dramatically reduced the prey population, forcing jaguars to compete with domestic animals and reduce their chances of survival.
“We are facing a silent extinction of prey species in the Atlantic Forest,” says Katia Ferraz, a wildlife biologist at the University of São Paulo. “We talk a lot about the extinction of jaguars, but little about the extinction of wild boar and deer, which are crucial infrastructure for their survival.”

The article “Loss of Prey Threatens the Extinction of Atlantic Forest Jaguars” appears to be first on Sicilianews24.it.

#Panthera[note 1] is a genus within the family #Felidae, and one of two extant genera in the subfamily Pantherinae. It contains the largest living members of the cat family. There are five living species: the jaguar, leopard, lion, snow leopard and tiger. Numerous extinct species are also named, including the cave lion and American lion.

This subject comes up fairly often, so I'm putting my mini-essay here as an easy reference. Feel free to share, or copy and paste with attribution, as you see fit. Comments, suggestions, and corrections are welcome. 🦖 🧪 🚀 ✍️

Michael Crichton's main reference when writing #JurassicPark was Gregory Paul's Predatory #Dinosaurs of the World. That's how we ended up with human size "velociraptors," later retconned to the considerably larger #Utahraptor. Although the poor creatures still have broken wrists and a severe case of mange.

Paul is a notorious #lumper, who likes shoving distantly related organisms into the same #taxonomic category. (The opposite of lumpers are #splitters, who try to put every specimen into as distinct a category as possible.) But even he never claimed they were the same species. Rather, he put them into the same genus, making #Deinonychus into another species of #Velociraptor, i.e. V. antirrhopus instead of D. antirrhopus.

This isn't entirely a crazy idea. Lots of modern genera have species with similar body plans but enormous size differences. Consider #Panthera, the big cats, which contains species from P. uncia, the #snowleopard, to P. tigris, the #tiger—even though tigers are generally about five times the mass of snow leopards, similar to the ratio between D. antirrhopus and V. mongoliensis.

However, there are enough other differences between Deinonychus and Velociraptor that even Paul has long since admitted this was a mistake. No #paleontologist now doubts they each belong in their own genus. Unfortunately, since Jurassic Park has so thoroughly cemented the idea of the big V, I doubt it will ever go away.
