More than half the world's human population lives within 100 km of the coast, and that number is expected to increase by 25% over the next two decades. Consequently, coastal ecosystems are at serious risk. Larger coastal populations and increasing development have led to increased loading of toxic substances, nutrients and pathogens with subsequent algal blooms, hypoxia, beach closures, and dam...

魚類養殖は残餌や糞粒などの多量の有機物を負荷する。我々は養殖の盛んな内湾で柱状堆積物試料を採取し,全有機態炭素(TOC),全窒素(TN)および全リン(TP)の鉛直分布を明らかにした。魚類養殖場のTOCとTNの分布は非養殖場と同様の鉛直分布を示したが,TP含量は非養殖場よりも高かった。餌のTP含量は小魚の小骨に由来するもので高く,魚類に消化されにくく,且つ堆積物中で分解されにくいと考えられる。TP含量を指標にして,魚類養殖による有機物負荷が明らかにできる可能性が考えられた。

The present study aims to investigate the effect of a trans-disciplinary design of curricula, deemed a powerful tool for teaching and research on complex environmental problems, with a goal to help solve the real problems that climate change has brought to the coastal environment in Taiwan. Three major real-life problems in southern Taiwan—declining mullet fisheries, flooding, and coral bleachi...

Coastal ecosystems lie at the forefront of sea level rise. We posit that before the onset of actual inundation, sea level rise will influence the species composition of coastal hardwood hammocks and buttonwood (Conocarpus erectus L.) forests of the Everglades National Park based on tolerance to drought and salinity. Precipitation is the major water source in coastal hammocks and is stored in th...
