Research Description Taxonomicand functional profile of soil microbial communities (SMC) will potentially accelerate researches on natural microbial communities which can promote the adaptive capacity of host plants to abiotic stresses such as high calcium stress, in a karst ecosyste. Data from this study will also be valuable for determining which microbial strains can be used for field application in karst topography. Soil microorganisms such as actinomycetes and vesicular-arbuscular mycorrhiza play a significant role in soil biogeochemical cycling but their growth and activities are often limited by resource availability. Studying soil processes that are driven by these microogranisms will help elucidate controls on soil fertility and improve the ability to predict the responses of an ecosystem to globla changes. Moreover, baseline data generated from this study may provide valuable insight on this particular type of ecosystem and may pave away in long-term of microbial diversity.
Research Objectives General: This study aims to describe the taxonomic diversity and metabolic functions of bacterial and fungal communities present in forest over limestone ecosystems using metagenomic analysis. Specifically, this study aims to: 1) isolate and cultivate selected ecologically important microbial groups; (2) describe the taxonomic and functional diversity profile of bacterial and fungal community of soil rhizosphere samples using metagenomic analysis and; (3) correlate the distribution and function of bacterial and fungal communities with existing physicochemical parameters of the soil in relation to ecosystem health and conservation.

Research Accoplishments [CY 2018] The results from this study may provide an assessment of microbial communities in Philippine forest over limestone and reveal the impact of vegetation and changes in the environment on bacterial and fungal community composition in the karst habitats. In addition, in our best knowledge, this is the first study utilizing cultureindependent approach to determine microbial diversity in forest over limestone, aiming to fully represent all possible ecosystems in the Philippine archipelago. This study may also foster stronger research collaboration between and among various institutions, paving the way for enhanced research capability and development of research expertise through mentoring and training
