Abstract
The life cycle and behavior of free-living soil nematodes is highly dependent on environmental factors such as temperature and soil moisture, fluctuations leading to significantly lower development and activity rates, dormancy and/or mortality. This literature review summarizes present knowledge about free-living soil nematode temperature and moisture requirements, as well as the commonly accepted predictions about climate change-induced temperature and precipitation changes in Norway. The available information is analyzed and the potential effects of a changing climate on soil nematode communities are discussed. Finally, the influence of an altered nematode community the rest of the soil ecosystem including other soil organisms such as... (More)

Popular Abstract
Free-living soil nematodes are a vital part of their ecosystem, contributing to important processes such as litter decomposition and nutrient mineralization, as well as population control of other soil organisms. Their life cycle and behavior is, however, highly dependent on environmental factors such as temperature and soil moisture, with fluctuations having the potential to alter their development and growth rates, or lead to dormancy and even mortality. Studies analyzing the nematode life cycle and their life requirements suggests that the enhanced moisture and a slight increase in temperature is expected to lead to higher growth and activity levels.

Free-living soil nematodes are a vital part of their ecosystem, contributing to important processes such as litter decomposition and nutrient mineralization, as well as population control of other soil organisms. Their life cycle and behavior is, however, highly dependent on environmental factors such as temperature and soil moisture, with fluctuations having the potential to alter their development and growth rates, or lead to dormancy and even mortality. Studies analyzing the nematode life cycle and their life requirements suggests that the enhanced moisture and a slight increase in temperature is expected to lead to higher growth and activity levels.
The ongoing climate change is likely to contribute to a change in the population dynamics of soil organisms, including nematodes. Current literature regarding climate change in Norway widely supports the idea that temperature and precipitation rates will increase, particularly in the northern region and in the winter. According to studies analyzing free-living soil nematode response to an increase temperature and moisture, these changes are likely to benefit nematodes, leading to enhanced litter decomposition and nutrient mineralization.
