Crocodile resilience reveals how climate refugia preserved ancient biodiversity through mass extinctions

Indigenous knowledge systems, such as those of the *Yolŋu* people in Australia or the *Munduruku* in the Amazon, treat crocodiles as cultural and ecological indicators, their behaviors tied to seasonal rhythms and land management practices like controlled burns and wetland restoration. These traditions document how crocodiles thrive in dynamic, human-shaped landscapes—contrasting sharply with the study’s static 'thermal refugia' model. For example, the *Munduruku* use crocodile migrations to predict flood patterns, a practice that could inform modern climate adaptation strategies. The omission of such knowledge reinforces the colonial erasure of Indigenous stewardship, which has preserved biodiversity for millennia despite industrial encroachment.
The crocodile survival story is not just about thermal refugia but a microcosm of how power, knowledge, and ecology intersect.
Western science’s focus on individual species traits obscures the systemic patterns—Indigenous stewardship, historical precedents, and cross-cultural ecological wisdom—that have sustained biodiversity for millennia, while marginalized communities bear the brunt of habitat loss despite their solutions. The *trickster* edge reveals how the narrative’s solemnity conceals deeper ironies: crocodiles, once demonized as threats, now symbolize resilience in a world where human activity is the true existential risk. To move forward, conservation must integrate Indigenous fire ecology, paleoecological resilience hubs, and artistic-spiritual frameworks to rewrite the story—not as a tale of survival, but as a blueprint for collective adaptation. The actors here are not just crocodiles but the networks of knowledge, land, and culture that have kept ecosystems alive through cataclysms, a lesson critical for the Anthropocene.
