A study led by researchers from Proyecto Yaguareté found that more than 85 percent of jaguar habitat was lost in the Atlantic Forest – the ecological region of nearly 2 million square kilometers that covers the Argentine province of Misiones, Paraguay and reaches the center of Brazil – and that populations currently resist at only 3 percent of its original territory. The study, which was published this week in the journal Scientific Reports is based on data from 14 research groups from different countries, estimates that there are less than 300 specimens and that their mortality should be stopped to achieve conservation of the species.
