- Regime shifts explain much of the change in mesozooplankton biomass as well as the biomass change in many subarctic moth guilds
- Other important environmental factors were Winter NAO and the decreasing number of ice days for zooplankton and previous summer’s temperatures affecting the parent generation for moths.
- The same climate regulation mechanisms affect invertebrates in water and on land, but often in contrasting ways
- Total invertebrate biomasses only tell a part of the truth: biomass trends of different functional groups vary considerably
- Regime shifts and the NAO-index are useful proxies for complex climatic phenomena
