- Alexandre de Santi is Mongabay’s managing editor for Brazil, where he leads coverage of the Amazon and other national environmental issues.
- His career spans more than two decades, from founding the investigative studio Fronteira to serving as deputy editor at The Intercept Brazil, where he helped lead landmark investigations.
- Since joining Mongabay in 2022, Santi has brought a collaborative approach to investigative reporting, including editing a 2024 story that exposed links between Amazon carbon credits and timber laundering.
- This interview is part of Inside Mongabay, a series that spotlights the people who bring environmental and conservation stories to life across our global newsroom.

- A newly released “Atlas for the Americas Flyways” tracks the high concentrations of 89 migratory bird species that are at risk of major population decline throughout the western hemisphere. It identifies their breeding grounds, wintering areas and stopover locations.
- This marks the first time these hemispheric migratory routes have been mapped in such extreme detail. Hyper-specific location data aim to provide policymakers, conservationists and others with the necessary tools to make informed decisions about protecting migratory bird species all along their flyways.
- The atlas highlights migratory connectivity — identifying key locations in North, Central and South America. Maintaining the environmental integrity of these places is critical to supporting migratory species and includes many tropical hotspots such as Mexico’s Yucatán Peninsula and the Pantanal wetland in Brazil and Paraguay.
- The atlas will also be of use to researchers trying to understand why a species’ population is declining. It can also help planners mitigate perilous threats by providing geographical data as to where, and where not, to build infrastructure.

From fish and turtles, to hippos and crocodiles, about 43% of all known large freshwater animal species have been deliberately introduced into ecosystems outside their native ranges, a recent study finds. Most species were introduced to boost fisheries, food security or tourism, but many have had unintended consequences for local wildlife, habitats and people. Fengzhi […]
