Conservation of forest soil microbial diversity: the impact of fire and research needs

While increasing attention has been given to issues surrounding biodiversity in recent years, little is known about the diversity of forest soil microorganisms. This is a serious gap in knowledge given the significant roles played by microorganisms in ecosystem functioning. This paper addresses issues surrounding conservation of microbial diversity in forest soils with an emphasis on the impact of fire. Recently developed techniques such as phospholipid fatty acid profiling, DNA reassociation, and carbon substrate utilization will also be reviewed for their applicability to biodiversity research. Future research needs are also discussed.Key words: biodiversity, conservation, forest soils, fire, microbial diversity.
