Selecting Socio-Economic Metrics for Watershed Management

The selection of social and economic metrics to document baseline conditions and analyze the dynamic relationships between ecosystems and human communities are important decisions for scientists, managers, and watershed citizens. A large variety of social and economic data is available but these have limited use without theoretical frameworks. In this paper, several frameworks for reviewing social-ecosystem relations are offered, namely social sanctions, sense of place, civic structure, and cultural differences. Underlying all of these frameworks are attitudes, beliefs, values, and norms that affect which questions are asked and which indicators are chosen. Much work and significant challenges remain in developing a standard set of spatially based socio-economic metrics for watershed management.

东太湖渔业发展对水环境的影响及其生态对策

东太湖网围养殖始于1984．至今养殖面积达3200hm^2。占东太湖面积的24％以上。网围养殖的盲目发展带来了湖泊的水质污染．沼泽化等环境问题。为保护东太湖水域环境。必须明确湖泊功能定位。减少湖泊污染源。并在此基础上进行人工调控．合理放养。完善湖泊生态系统结构。针对东太湖水生植被退化的趋势。应恢复和加强对优质水生植被的保护。促进湖泊生物多样性。恢复其良性生态。

Influence of glucose feeding on the ligninolytic enzyme production of the white-rot fungus Phanerochaete chrysosporium

The present work studied the influence of glucose feeding on the ligninolytic enzyme production of Phanerochaete chrysosporium in a nitrogen-limited (C/N ratio is 56/8.8 mmol/L) medium. Several sets of shaking flask experiments were conducted. The results showed that 2 g/L glucose feeding on the first day of the culture (24 h after the inoculation) simulated both fungal biomass growth and enzyme production. The manganese peroxidase (MnP) activity was 2.5 times greater than that produced in cultures without glucose feeding. Furthermore, the glucose feeding mode in fed-batch culture was also investigated. Compared to cultures with glucose feeding every 48 h, cultures with glucose feeding of 1.5 g/L (final concentration) every 24 h produced more enzymes. The peak and total yield of MnP activity were 2.7 and 3 times greater compared to the contrast culture, respectively, and the enzyme was kept stable for 4 days with an activity of over 200 U/L.

室内培养底栖端足类日本大螯蜚饵料研究

本文在实验条件下探讨了５种饵料对海洋底栖端足类日本大螯蜚的培养效果。实验指标为存活率，生长速度，日增长率和发育状况。结果表明，青岛大扁藻与新月菱形藻１：１混合液的培养效果最佳，合成饲料是较好的补充饵料，螺旋藻粉不宜作为日本大螯蜚的培养饵料。动物性饵料培养效果不如植物性饵料，但对日本大螯蜚的早期快速成长具有一定的促进作用。
