In varying degrees, local and regional extinction, long-distance colonization, and local recruitment may all contribute to the exceptional character of these communities. Also, it is debated whether mountain endemics mostly originate from local lowland taxa, or from lineages that reach the mountain by long-range dispersal from cool localities elsewhere. Here we investigate the evolutionary routes to endemism by sampling an entire tropical mountain biota on the 4,095-metre-high Mount Kinabalu in Sabah, East Malaysia. We discover that most of its unique biodiversity is younger than the mountain itself (6 million years), and comprises a mix of immigrant pre-adapted lineages and descendants from local lowland ancestors, although substantial shifts from lower to higher vegetation zones in this latter group were rare. These insights could improve forecasts of the likelihood of extinction and 'evolutionary rescue' in montane biodiversity hot spots under climate change scenarios.

L. asclepiades, L. rufescens, L. xanthocyana and S. bisignata are redescribed, and three species of Libellago- one with four subspecies - are described as new to science, viz. the closely allied L. daviesi sp. nov. from the northern arm of Sulawesi and L. man-ganitu sp. nov. from Sangihe Island, north of Sulawesi, and a complex of four mainly parapatric subspecies allied to L. rufescens, viz., L. celebensis sp. nov. from W part of Central Sulawesi, and nominotypical subspecies, L. celebensis anoa ssp. nov. from NE part of South Sulawesi, L. celebensis dorsonigra ssp. nov. from NE part of South Sulawesi, and L. celebensis orientalis ssp. nov. from extreme E part of South Sulawesi, E part of Central Sulawesi and Southeast Sulawesi. The status of the genus Sclerocypha is discussed. A key to the species of Chlorocyphidae (except Rhinocypha) known from Sulawesi, is provided.

Several indicators have been proposed to assess progress towards the 2010 target, two of them addressing directly the issue of species decline. In Europe, the Fauna Europaea database gives an insight into the patterns of distribution of a total dataset of 130,000 terrestrial and freshwater species without taxonomic bias, and provide a unique opportunity to assess the feasibility of the 2010 target. It shows that the vast majority of European ...
