In an effort to better understand environmental challenges, a group of Asian scientists established the East Asia Pacific (EAP) ILTER. These remarkable scientists held its first regional meeting in 1995. Since then, they have connected regional scientists to global ecological research opportunities and tirelessly promoted and trained the next generation of young regional scientists, in addition to many other accomplishments.  Their contributions are truly remarkable. Their untold stories will be shared. 

 

The growing complexity in the ecosystem structure and functions, under climate and land-use changes, requires interdisciplinary understandings on the processes and whole-system, accurate estimates of the changing functions, and delivering those knowledge to the society for sound decision making toward the sustainability of biodiversity and ecosystems.

Long-term observations on riverine invertebrate communities are crucial to assess potential impacts of climate change on stream ecosystems. In my talk I will present results from three recent studies: In the first study we examined LTER data (10–32 years) of 26 streams and rivers from four European ecoregions, to investigate invertebrate community responses to changing climatic conditions. Taxa and ecoregions differed substantially in their responses.

Since its founding in 1993 the International Long-term Ecological Research Network (ILTER) has gone through pronounced development phases. The current network comprises 44 active member LTER networks representing 700 LTER Sites and ~80 LTSER Platforms across all continents, active in the fields of ecosystem, critical zone and socio-ecological research. The critical challenges and most important achievements of the initial phase have now become state-of-the-art in networking for excellent science.

Dong Khanthung Protected Forest (DKPF) is a provincial protected area in southwestern Laos. These Protected Forests form a complex that supports what is regarded as a very rich fauna of unique species of endangered wildlife. However, the information about these unique wildlife species is very limited and so the capacity to conduct proper management is hindered by the lack of knowledge of even basic distributional data. Therefore, the aim of this study is initially raised the information about unique wildlife for improving the management and conservation of biodiversity in DKPF.

The Myanma Selection System (MSS) has been applied in the management of the natural teak-bearing forests in Myanmar for nearly 150 years now with the belief that it can sustain the forests and teak yields. Nevertheless, over the past years the teak forests have both depleted and degraded significantly. Without a doubt, the main causes of this resource depletion and degradation included illegal cuttings, legal over-exploitation, agricultural expansion, shifting cultivation and lack of timely silvicultural treatments.

Through litter decomposition enormous amount of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to understand the controls on the terrestrial carbon transfer to the atmosphere. However, previous studies were mostly based on site-specific litter and methodologies, adding major uncertainty to syntheses, comparisons and meta-analyses across different experiments and sites.

Both gradual climate change and extreme climate events have major effects on ecosystem dynamics. Not surprisingly evidences from empirical studies are rare because long-term studies, which are rare, are often required to disentangle background fluctuation and changes related to climate change. Due to the long-term nature LTER could provide the most direct evidences of ecosystem response to gradual climate change and extreme climate events.

The Danungdafu Forestation Area (DFA) represents one of the most controversial case concerning land use and indigenous rights in Taiwan. Since 2012, we have been studying this social-ecological system from interdisciplinary perspectives, which include researches on governance, wildlife ecology, land use change, ecosystem processes and services, citizen science, regional sustainability indicator, land use preference, and agri-environmental policy. Research findings show that, historically, the transformations of the DFA have been dominated by external systems.

Climate change causes effects on biodiversity and conservation and sustainable use of biological resources. This research conducted in Tung Yai-Huai Kha Khaeng World Heritage Site aims to map the distributions of important trees and plant communities and to assess shifts in distributions as the results of future climate change. Occurrences of trees were gathered from nationwide forest resource inventory. Maxent model was used to predict the distribution of trees; while cluster analysis and geographic information system (GIS) were employed to classify plant communities.
