Researchers are conducting a comprehensive study of Arctic ecosystems in Alaska to understand whether interconnected species can collectively adapt to rapid environmental change caused by climate warming. The project, called the Evolving Meta-Ecosystems Institute (Evome), is supported by the US National Science Foundation and involves approximately 50 scientists from US research institutions examining five key species and their relationships across tundra and stream environments along Alaska’s North Slope.
The study focuses on how warming temperatures are transforming the Arctic faster than any other region on Earth. Snow melt patterns are shifting, altering water flow timing and stream conditions. Willow shrubs are expanding across river valleys—a process termed shrubification—which affects nutrient cycling and habitat conditions. These changes have cascading effects throughout the ecosystem, potentially disrupting the aquatic insects like mayflies and stoneflies that form the foundation of food webs for both fish and birds.
Scientists are examining the white-crowned sparrow, feltleaf willow, Arctic grayling, aquatic mayfly species, and ground beetles to understand how their individual adaptations may occur in response to one another rather than in isolation. The research hypothesis suggests that species with long-standing ecological relationships may be able to co-evolve and adapt together, potentially maintaining ecosystem stability even as climate conditions change dramatically. This represents a departure from traditional views of evolution as purely competitive individual survival.
The project utilizes a sprawling network of 15 field sites across nearly 190 miles along the Dalton Highway, where researchers deploy sticky traps, recording equipment, temperature sensors, and mesh bags to collect data throughout spring and summer. Initial observations suggest that while some conditions—such as reduced algae production in shadier streams—may disadvantage certain species, increased foliage from expanding willows could benefit leaf-shredding insects. Project leaders express cautious optimism that Alaska’s ecosystems may continue functioning, though they acknowledge this represents an educated assessment rather than certainty.
