Recently, taphonomic representation of biota in the lithosphere has been widely used for minimizing the biases in palaeo-environmental reconstructions including global climate change. In September 2001, a sediment trap was installed at the central area of the Loch Coire Fionnaraich （LCFR）, a small, oligotrophic mountain loch in northwest Scotland for a taphonomic study of cladoceran zooplankton. The trap was emptied on a seasonal basis, where an average 0.14 g dry material was recovered in each season, January, May and August 2002 respectively. A sediment core was also taken from near the sediment trap location. The top 0.5 cm section, the ＇core＇ was used for a comparative study with the trap sediment samples. The planktonic Cladocera consisted of Bosmina coregoni and appeared to have excellent preservation in the trap assemblages. Moreover, some common littoral Cladocera such as Alonella excisa and Aloha guttata appear to be less well preserved in the fossil assemblages. Large littoral taxa such as Eurycercus lamellatus and Aloha quadrangularis were rare in the trap but relatively common and well preserved in the sediment-water interface. It is suggested that taphonomic processes play a dominant role on deposition of fossil remains of Cladocera and caution should be taken while inferring the past environmental changes whilst using fossil assemblages recovered from the lake centre as a representation of the entire cladoceran community in the lake.展开更多

Eighteen manuscripts of the meeting presentations were selected in this special issue. According to the four themes set in the ICBC meeting, this special issue include four sections, i.e., Coastal Biodiversity under Global Change, Adaptation and Evolution to Special Environment of Coastal Zone, Sustainable Utilization of Coastal Bioresources, and Coastal Biotechnology. Recent advances in these filed are presented.展开更多

There are advantages and disadvantages of doing business globally. Globalization had also brought about many challenges to entrepreneurs in the management of their organization. The values and beliefs of managers and staff across the globe influence visions, missions of their organization. Culture, resources and business practices of countries vary widely. Entrepreneurs must deal with global issues side by side with domestic considerations. This paper looks into how the theories and model of strategic management remain useful and relevant to entrepreneurs in a globalized business world especially in a turbulent economy.展开更多
