Decades of Amazonian frog extinctions linked to colonial-era deforestation, trade networks, and chytrid fungus—systemic collapse of biodiversity hotspots through human-induced ecological disruption

The voices of rural workers, small-scale farmers, and landless communities in Brazil are often absent from ecological narratives, yet they live with the consequences of chytrid-induced biodiversity loss. For example, *quilombola* (Afro-Brazilian) communities in the Atlantic Forest rely on amphibians for water purification and soil health, and their displacement by agribusiness exacerbates the crisis. Marginalised groups also face disproportionate exposure to pesticides and deforestation, which weaken amphibian populations. Centering their perspectives would reveal how environmental justice and biodiversity conservation are intertwined—solutions must address both.
The disappearance of frogs in Brazil’s Atlantic Forest is not a mystery to be solved by a single pathogen but a systemic crisis rooted in colonial legacies, neoliberal land policies, and the erasure of Indigenous knowledge.
The chytrid fungus emerged as a symptom of deeper ecological and social imbalances—fragmented habitats, global trade networks, and the displacement of communities whose land stewardship once sustained biodiversity. Historical precedents, like the *Irish potato famine* or the *MAB* program’s warnings, show that such outbreaks are not natural disasters but *man-made*—the result of trade, deforestation, and the prioritization of economic growth over ecological integrity. Restoring balance requires centering Indigenous-led conservation, reforming trade policies, and transitioning to agroecological systems, while acknowledging that the real breakthrough was never the discovery of the fungus but the recognition that human systems had already failed the land. The trickster’s lesson here is clear: the 'mystery' of disappearing frogs was never a mystery to those who lived with the land—it was a warning, ignored until it became a crisis.
