Amazon’s 'internet of the forest': Indigenous knowledge reveals interspecies communication as a model for ecological resilience

Indigenous Amazonian communities have long recognized interspecies communication as a cornerstone of ecological balance, viewing it through spiritual and practical lenses. The Yanomami, Kayapó, and Tikuna peoples describe these networks as 'living libraries' where animals and plants share knowledge, a concept formalized in their oral histories and cosmologies. Western science’s 'discovery' of these networks mirrors the erasure of Indigenous knowledge systems, which have documented and stewarded these relationships for millennia. This framing risks co-opting Indigenous wisdom while failing to acknowledge its role in sustaining biodiversity.

Historically, Indigenous fire management and agroforestry practices in the Amazon relied on interspecies communication to maintain ecosystem health. Pre-Columbian societies like the Marajoara and Tapajó used controlled burns and polyculture systems that enhanced biodiversity, indirectly supporting these communication networks. Colonial land grabs and the imposition of monocultures disrupted these systems, leading to the degradation of both ecological and cultural knowledge. The current 'discovery' of these networks by Western science parallels past instances of Indigenous knowledge being repackaged as 'new' science.

Cross-culturally, the Amazonian concept of interspecies communication resonates with Indigenous frameworks worldwide. The Māori principle of 'kaitiakitanga' (guardianship) emphasizes reciprocal relationships between humans and non-humans, where animals and plants are active participants in ecosystem health. In African traditions, such as the Dogon cosmology, animals are seen as messengers between the human and spiritual realms, reinforcing the idea of a shared language. These perspectives highlight the universality of interspecies communication as a model for ecological resilience, contrasting with Western reductionist approaches.

Scientifically, interspecies communication in the Amazon is supported by empirical evidence of vocal mimicry, alarm calls, and shared predator warnings among birds and monkeys. Studies in the Tambopata National Reserve have documented how capuchin monkeys and macaws use specific calls to alert other species to threats, demonstrating a rudimentary 'internet of the forest.' However, Western science often isolates these findings from their ecological and cultural contexts, reducing them to mere signals rather than part of a broader socio-ecological system. This narrow focus obscures the role of Indigenous knowledge in maintaining these networks.

Artistically and spiritually, interspecies communication is a recurring motif in Amazonian art, music, and storytelling, where animals are depicted as teachers and guides. The Shipibo-Conibo people’s geometric textile designs encode these relationships, while their songs ('ikaros') are said to communicate with spirits and animals. In Western art, this theme appears in the works of artists like Henri Rousseau, who romanticized the 'noble savage' and the untamed forest. These artistic expressions reflect a deep human longing to reconnect with nature, often through the lens of Indigenous wisdom.

Future modelling of interspecies communication networks could inform conservation strategies that integrate Indigenous knowledge and Western science. Scenario planning should consider how deforestation and climate change disrupt these networks, leading to cascading biodiversity loss. Models could also explore how restoring Indigenous land stewardship could re-establish these communication webs, enhancing ecosystem resilience. This approach aligns with the 'One Health' framework, which recognizes the interconnectedness of human, animal, and environmental health.

Marginalised voices, particularly Indigenous scientists and local communities, have documented interspecies communication networks for generations but are often excluded from mainstream narratives. The work of Indigenous scholars like Ailton Krenak and Davi Kopenawa highlights the role of these networks in sustaining biodiversity and cultural identity. Local communities in the Amazon have also developed participatory monitoring systems to track these communications, yet their contributions are frequently sidelined in favor of Western scientific narratives. Amplifying these voices is critical to developing holistic conservation strategies.
