Logging and forest conversion are occurring at alarming rates in the tropical forests of Southeast Asia. These disturbances alter soil chemistry, microbial diversity, and disrupt carbon cycling through shifts in litter decomposition. Direct links between microbial diversity and soil properties such as pH are well established; however, the indirect impacts of logging and forest conversion on microbial diversity and litter decomposition are poorly understood. We used surface (5 cm) soil to assess soil physicochemical properties, next-generation DNA sequencing to assess soil microbial diversity, and standardized litterbags to assess litter decomposition stabilization at five sites along a land use disturbance gradient in the tropical montane forests of Sabah state in eastern Malaysia. We used a hierarchical approach to explore how land use disturbance affects soil properties; how those soil properties in conjunction with land use disturbance affect soil microbial diversity; and how each of those factors affects litter decomposition and stabilization. We show that soil pH, total nitrogen, and bacterial diversity increase with time since disturbance; and sulfur, total carbon, percent sand, soil organic matter, and fungal diversity display a peaked response with peak around 100 years since the last disturbance. Fungal diversity is positively correlated with onsite forest cover, litter decomposition rate, and litter stabilization. Bacterial diversity shows a positive linear relationship with litter decomposition rates, but a peaked relationship with litter stabilization with peak around the mid-range of bacterial diversity. In summary, soils of the older forests harbor significantly greater microbial diversity and stabilize greater amounts of litter than soils of the younger forests and converted sites. Our results suggest that logging and forest conversion significantly affect soil microbial diversity and have lasting effects on carbon cycling in tropical montane forests.

Download Restoring Tropical Forests Book in PDF, ePub and Kindle
Restoring Tropical Forests is a user-friendly guide to restoring forests throughout the tropics. Based on the concepts, knowledge and innovative techniques developed at Chiang Mai University's Forest Restoration Research Unit, this book will enable improvements in existing forest restoration projects and provide a key resource for new ones. The book presents three aspects of the restoration of tropical forest ecosystems: the concepts of tropical forest dynamics and regeneration that are relevant to tropical forest restoration, proven restoration techniques and case studies of their successful application, and research methods to refine such techniques and adapt them to local ecological and socio-economic conditions.

Download Impacts of Leaf Litter Diversity and Root Resources on Microorganisms and Microarthropods (Acari, Collembola) During Early Stages of Decomposition in Tropical Montane Rainforest Ecosystems Book in PDF, ePub and Kindle
Soil organisms influence organic matter turnover and nutrient cycling via processing of organic matter entering the soil as litter and root-derived resources. Plant species differ enormously in the quality and quantity of litter and roots that they produce, and this diversity strongly modifies decomposition of litter by decomposer organisms. Higher plant diversity is generally assumed to improve habitat conditions and availability of resources, thereby improving the abundance and activity of decomposer organisms. Tropical Andean montane rainforest ecosystems harbor an exceptional diversity ...

Download Why Forests? Why Now? Book in PDF, ePub and Kindle
Tropical forests are an undervalued asset in meeting the greatest global challenges of our time—averting climate change and promoting development. Despite their importance, tropical forests and their ecosystems are being destroyed at a high and even increasing rate in most forest-rich countries. The good news is that the science, economics, and politics are aligned to support a major international effort over the next five years to reverse tropical deforestation. Why Forests? Why Now? synthesizes the latest evidence on the importance of tropical forests in a way that is accessible to anyone interested in climate change and development and to readers already familiar with the problem of deforestation. It makes the case to decisionmakers in rich countries that rewarding developing countries for protecting their forests is urgent, affordable, and achievable.
