Rapid warming is predicted to increase insect herbivory across the tundra biome, yet how this will impact the community and ecosystem dynamics remains poorly understood. Increasing background invertebrate herbivory could impede Arctic greening, by serving as a top-down control on tundra vegetation. Many tundra ecosystems are also susceptible to severe insect herbivory outbreaks which can have lasting effects on vegetation communities.

- The study focuses on the population dynamics of Aedes nigripes mosquitoes in western Greenland, analyzing how food resources (aquatic biofilms) and predators (diving beetles) influence these dynamics.
- Researchers tracked mosquito and predator populations across eight ponds in spring 2018, finding that resource quality and competition among mosquitoes played a more significant role in population performance than predation pressure from beetles.
- Despite initial high mosquito densities leading to increased mortality, better resource quality did not result in corresponding increases in adult mosquito fitness, highlighting the impact of resource availability on mosquito populations.
