Short summary

This work deals with one of the central topics in biogeochemistry, the factors controlling the degradation of organic matter. We found the contribution of dissolved (cell-free) to the total extracellular enzymatic activities follows a strong seasonal pattern, with the largest proportions during cold periods. Our results suggest that temperature changes can have strong implications in the hydrolysis of organic matter, suggesting a link between global warming and the degradation of organic matter.
