Swidden agriculture, or shifting cultivation, is variously viewed as a great environmental threat or a sustainable system of land use. In Laos, swidden has long been considered the primary driver of forest loss nationwide, but the assessment is based exclusively on studies from the north of country, where deforestation is most severe. National policies to control swidden have percolated down to management of one of the largest nature reserves in the region, Nakai-Nam Theun National Protected Area (NNT NPA) in the Annamite Mountains of central Laos. In NNT NPA, swidden&amp;#8217;s presumed unsustainability and deleterious impact on forest cover is an untested assumption.  We tested it by methods of historical ecology, tracing the patterns of NNT&amp;#8217;s...

A new species of Dalbergia (Leguminosae, Dalbergieae) from Western Africa
Provedor de dados: 16
Autores: Jongkind, C.C.H.
Dalbergia hepperi from Western Africa is described and illustrated. The combination of glabrous ovaries, flat and glabrous fruits and ovate to obovate leaflets with a conspicuous acuminate apex is not known from any other Dalbergia species from this region.

Notes on Malesian Fabaceae (Leguminosae-Papilionoideae) 17. The genus Dalbergia
Provedor de dados: 16
Autores: Adema, F.; Ohashi, H.; Sunarno, B.
A systematic treatment of the genus Dalbergia for the Flora Malesiana (FM) region is presented. The treatment includes a genus description, two keys to the species, an enumeration of the species present in the FM-area with names and synonyms, details of distribution, habitat and ecology and where needed some notes, three new species (D. minutiflora, D. pilosa, D. ramosii) are described. A new name for D. polyphylla is proposed (D. multifoliolata). The paper also contains an overview of the names, a list of collections seen and references to the literature.

Laboratory decomposition of Dalbergia nigra all. ex. benth and Eucalyptus grandis w.hill ex. maiden leaves in forest and eucalypt plantation soils
Provedor de dados: 39
Autores: Rezende,Juliana L. P.; Garcia,Queila S.; Scotti,Maria Rita M. M. L.
The objective was to evaluate the decomposition of D. nigra and E. grandis leaves under laboratory conditions when incubated in soils from Atlantic Forest and from a 40-year-old eucalypt plantation for a year. The obtained values of pH in forest and eucalypt plantation soils were 5.61 and 4.47 and for aluminum 0.32 and 1.89mEqx100, respectively. A great number of microorganisms (total fungi, phosphate solubilising and cellulolytic organisms) were found in forest soil. Litterbag study revealed a higher mass loss of the leaves in forest soil in the first four months (c. 30%). In the eucalypt plantation soils loss was observed only after eight months (c. 40%). The initial contents of N and P were greater in D. nigra than in E. grandis leaves, although lignin...
