Studying infrequent phenomena (e.g. hurricanes) and slow processes (e.g. forest regeneration) greatly challenges the ecological techniques of real-time studies. By combining the two relatively new approaches of paleotempestology and fine-resolution palynology, this study provides insight into the impacts of hurricanes and the post-hurricane regeneration of forests. I analyzed a 5-m sediment cor...

Protected areas in Thailand were first established 40 years ago. The total area of existing protected areas covers 18.2% of the country's land area and the Class 1 Watershed, another form of protection, encompasses 18.1%. The government of Thailand intends to increase protected area systems to 25% of the country in 2006 and 30% in 2016. There are always questions arising about how much is enoug...

Climate change is constant. The average temperature has risen since the globe was encased in ice millions of years ago. Current climate caused by natural events and human behavior treating managing environment. huge burning coal, oil, wood deforestation economic development seriously damaged world's climate. Global may alter peat carbon stored forest land fires. Human activities like plantation...

The paper reports on experimental analysis of the spatial statistics (texture), as measured by wavelet frames in Lband SAR observations of tropical forest. Signatures are used to characterize the dependences of the texture measures on scale and polarization state. For detected data, experiments performed using a full resolution (12.5 m) JERS-1 image confirm that textural features provide good s...
