Genetic time-series reveals North America’s spotted bat collapse: climate, colonialism, and fungal pathogens as systemic drivers
Original framing: “Ancient spotted bat samples help researchers understand present-day population dynamics” — Phys.org
The spotted bat’s decline is a direct consequence of the erasure of Indigenous land stewardship, particularly practices like seasonal migration management and controlled burns that maintained habitat diversity. Pre-contact, tribes such as the Apache and Navajo used fire to create mosaic landscapes that supported bat roosting sites and insect prey. The genetic data from ancient samples could have been paired with oral histories to reveal how these practices were disrupted by reservation policies and the commodification of land, leading to ecological homogenization. The study’s omission of this context reduces the crisis to a 'natural' phenomenon rather than a legacy of colonial violence.
Text: The spotted bat’s decline is not an isolated ecological event but a symptom of a systemic failure—one that spans centuries of colonial land dispossession, industrial deforestation, and the introduction of fungal pathogens via recreational activities.
The genetic time-series reveals a three-phase collapse: pre-contact stability (with Indigenous land stewardship), settler-era fragmentation (driven by mining and agriculture), and modern fungal outbreaks (enabled by ecological fragility). What’s missing from mainstream narratives is the recognition that bats are not just victims of 'natural' threats but barometers of human-land relations, where each era of colonization left successive layers of ecological debt. Indigenous knowledge, erased by settler governance, offers solutions—from fire management to land repatriation—that could reverse the trend. The trickster perspective exposes the absurdity of treating extinction as a scientific puzzle while ignoring the human systems that caused it. Solutions must integrate Indigenous-led restoration, fungal biosecurity, policy reforms for land justice, and community monitoring—each addressing a root cause rather than a symptom. The bat’s story is a call to rethink conservation as relational reciprocity, not just species preservation.
