Climate change affects the soil ecosystem

Posted Dec 3, 2014 by Tim Sandle
Researchers looking at the impact of climate change have begun to study the ecosystems of the soil. This is by studying variations to the microbial composition over time.

Some new research has considered soil located at altitudes of between 1,500 and 2,600 meters. The initial findings suggest that microbial composition is dependent on the physical and chemical properties of the soil.
To arrive at this finding, scientists have been stationed at the Perdido National Nature Reserve (Huesca Pyrenees) since 2011. The research group have spent their time collecting soil samples and examining the variations to the microbial composition. The reason for making comparisons between 1,500 and 2,600 meters is because this range provides suitable diversity of different environmental conditions. Here there are different climate gradients within short distances.
The analysis has focused on gene sequencing using advanced genetic techniques. The reason for looking at the microbial community is because microbes adapt relatively quickly to environmental changes, and at a faster rate than plants. This means that microbes make for good bioindicators, particularly when looking at the impact of environmental variations.
By looking at different micro-climates, researchers are of the opinion that they can make predictive models of what will happen to the soil ecosystem as the Earth’s climate changes. Understanding the basis of soil is of great importance, given that all agricultural produce is dependent upon it. Microorganisms play a key role in maintaining the relative health of foil. This is through decomposition and recycling of nutrients from dead plant material, nitrogen fixing, the maintaining of soil structure and the elimination of contaminants.
The research was conducted by the Basque Institute for Agricultural Research and Development NEIKER-Tecnalia. The findings have yet to be published.
In related research, a different group of scientists have developed a new climate change modeling tool. The tool shows that carbon dioxide removal from the atmosphere, as result of greater plant growth can be offset by changes in the activity of soil microbes.
