Jaguars in the Brazil-Argentina border forest have more than doubled since 2010

Jaguar population recovery in the Upper Paraná Atlantic Forest has more than doubled since 2010, the result of a coordinated conservation effort spanning Brazil and Argentina. The two countries built a continuous wildlife corridor of over 6,800 square kilometers linking their shared national parks, enabling jaguars to move, hunt, and breed across what was once a divided range. Joint patrols, shared data, and community programs that reduced retaliatory killings made the corridor function in practice, not just on paper. The recovery matters beyond one species, since protecting jaguar habitat shields hundreds of other plants and animals. Researchers now study this binational model as a replicable framework for large-carnivore recovery worldwide.

Whale tail, for article on sei whale return

Sei whales reappear in Argentine waters after nearly 100 years

Sei whales are back in Argentina’s coastal waters for the first time in roughly 100 years, after industrial whaling wiped them out in the 1920s and 30s. These blue-grey giants are the third-largest whales on Earth and among the fastest, which once made them prime targets for hunters. Their slow return — the species reproduces just once every two or three years — is a quiet testament to the 1946 international whaling treaty that gave them room to rebuild. Global numbers now sit around 50,000 and are trending upward, though sei whales remain endangered. Their reappearance off Patagonia carries a hopeful lesson for marine conservation everywhere: give a species enough time and enough protection, and it can find its way home.

Argentinian flag flying near a building, for article on crimes against trans women

In first, an Argentine court convicts ex-officers of crimes against trans women during dictatorship

Argentina just made legal history: a court in La Plata convicted 11 former officials of the 1976–1983 dictatorship for crimes against humanity specifically committed against transgender women — believed to be the first ruling of its kind anywhere in the world. Eight trans plaintiffs took the stand to testify about rape and torture at the Banfield Pit, one of the country’s largest clandestine detention centers. Ten defendants received life sentences; one was sentenced to 25 years. When the verdict was read, survivors and families packed the courtroom and wept. Argentina has been quietly building the world’s most ambitious reckoning with state terror, and this ruling extends that work to a community long left outside official memory — a model other nations are studying.
