Promoting regional sustainability by eco-province construction in China: A critical assessment

The regional level has been recognized as a good scale for implementing actions towards sustainable development (SD). An important pathway to improve regional sustainability is to locally carry out long-term ecological planning. In order to reduce environmental impacts from fast economic growth, several eastern provinces of China began Ecological Province Construction (EPC) at the end of 1990s. This paper presented a case for analyzing the progress of EPC in China via both qualitative and quantitative methods. We studied Shandong Eco-province Construction (SEPC) and evaluated its outcomes with its pre-set indicators in 2003–2010. A further evaluation with eco-efficiency and de-linking indices was conducted. The results indicated the pre-set indicators could not effectively reflect of the ecological province construction. It was recommended to introduce an evaluated framework combined with eco-efficiency and de-linking indices to indicate ecological planning at the regional scale.

Where ichthyofaunal provinces meet: the fish fauna of the Lake Edward system,East Africa

Based on literature, museum collections and three recent expeditions, an annotated species list of the Lake Edward, East Africa, drainage system is presented, excluding the endemic haplochromines. A total of 34 non-Haplochromis species belonging to 10 families and 21 genera are recorded from the system. Three of these are endemic and two others have been introduced in the region. Six species are new records for the Lake Edward system. A species accumulation curve indicates that we probably covered most of the non-Haplochromis species in the area sampled during the recent expeditions, but undetected species might still be present in the Congolese part of the system, which is poorly sampled. A comparison of the species list with those of neighbouring basins confirmed the placement of the Lake Edward system within the east-coast ichthyofaunal province.

云南猪屎豆属植物订正

This paper is a revision of genus Crotalaria(Papilionaceae) in Yunnan. 30 species and 2 varieties of this genus have been described so far. Hence, there are 27 species, including 4 exotic species, and 4 varieties are distributed in this very province. Among them, 1 new variety, C. mairei var. pubescens, and 3 new combinations, C. yunnanensis var. heqingensis, C. peguana var. qiubeiensis, and C. albida var. gengmaensis, and 1 new record of China, C. humifusa, are included. In addition, 2 species are combined, they are C. jingpingensis to C. prostrata and C. yuanjiangensis to C. medicaginea. Besides, the pollen morphology in some taxa of this genus has been examined.
