Abstract

Climate change and land-use change are two of the most important drivers of diversity loss among macrobial taxa. These pressures are especially strong in the tropics, where the effects of climate change may be severe and where economic pressures to convert land to human use are strong. The impact of these two global change drivers on microbial communities, however, is not well studied. Understanding this is important because microorganisms comprise most of the world's biological diversity and play essential roles in the biogeochemical processes that make life possible for higher orders of taxa. In this chapter we review the literature on the impact of these key global change drivers on soil microbial communities and several key microbial mediated biogeochemical processes in the tropics. We find evidence that both climate and land-use change impact the composition and functioning of tropical microbial communities. These two factors may interact, potentially amplifying the consequences of climate change. We propose research priorities for improving understanding of microbial responses to climate- and land-cover change read more ...
