Ultramafic nickel laterites in Indonesia (Sulawesi, Halmahera) : Mining, nickel hyperaccumulators and opportunities for phytomining

Indonesia (Sulawesi and Halmahera Islands) has some of the largest surface exposures of ultramafic bedrock in the world, and these are the sites of productive lateritic nickel mining operations. The proven and potential use of native plant species of ultramafic outcrops in mine rehabilitation can help drive conservation efforts, and nickel hyperaccumulators in particular can potentially be used in phytomining. The phytomining operation uses hyperaccumulators to extract residual nickel from stripped land. As such, in the foreseeable future, implementation of this technology is likely to be seen as a part of a progressive rehabilitation strategy of lateritic nickel mining in Indonesia. This approach ensures effective erosion control (e.g. 're-greening') while at the same time generating income by gaining residual nickel

Reviews

A joint project of the National Herbarium, Addis Ababa University, and the Department of Systematic Botany, Uppsala University, the Ethiopian Flora Project that was launched in 1980, continues to produce results since the first volume (in fact Vol. 3) was published. Many efforts have gone into fund raising, and SIDA, the Swedish International Development Cooperation (earlier SAREC), and the Ethiopian Government have contributed considerable sums of money to achieve the publication of the Flora of Ethiopia and Eritrea. The editorial team in Uppsala, Addis Ababa and Eritrea has to be congratulated that within two years after the appearance of both volumes of 1995 another issue has left the press. In this extremely rich flora region, with altitudes ranging from below sea level to 4413 m above with a multitude of climatological areas and niches a complete Flora that works has been sorely missed. Endemism is considerable. After a rather slow start, not in the last place caused by political and financial reasons, the authors have apparently contributed their shares at a much more rapid pace. The history of the organization of the writing of the Flora of Ethiopia has been elaborated in the first volume which appeared, no. 3 (Flora of Ethiopia), and the other volumes (Flora of Ethiopia and Eritrea) report on the progress made. In the title the independence of Eritrea since 1993 is reflected. Taxon 41 (1992) 403 provided scant information for Vol. 3

Panbiogeography of Nothofagus (Nothofagaceae): analysis of the main species massings

Aim  The aim of this paper is to analyse the biogeography of Nothofagus and its subgenera in the light of molecular phylogenies and revisions of fossil taxa. Location  Cooler parts of the South Pacific: Australia, Tasmania, New Zealand, montane New Guinea and New Caledonia, and southern South America. Methods  Panbiogeographical analysis is used. This involves comparative study of the geographic distributions of the Nothofagus taxa and other organisms in the region, and correlation of the main patterns with historical geology. Results  The four subgenera of Nothofagus have their main massings of extant species in the same localities as the main massings of all (fossil plus extant) species. These main massings are vicariant, with subgen. Lophozonia most diverse in southern South America (north of Chiloé I.), subgen. Fuscospora in New Zealand, subgen. Nothofagus in southern South America (south of Valdivia), and subgen. Brassospora in New Guinea and New Caledonia. The main massings of subgen. Brassospora and of the clade subgen. Brassospora/subgen. Nothofagus (New Guinea–New Caledonia–southern South America) conform to standard biogeographical patterns. Main conclusions  The vicariant main massings of the four subgenera are compatible with largely allopatric differentiation and no substantial dispersal since at least the Upper Cretaceous (Upper Campanian), by which time the fossil record shows that the four subgenera had evolved. The New Guinea–New Caledonia distribution of subgenus Brassospora is equivalent to its total main massing through geological time and is explained by different respective relationships of different component terranes of the two countries. Global vicariance at family level suggests that Nothofagaceae/Nothofagus evolved largely as the South Pacific/Antarctic vicariant in the breakup of a world-wide Fagales ancestor
