Tropical biodiversity: What are the biotic and abiotic environmental factors important to the evolution and maintenance of biodiversity in the most species-rich and endangered ecosystem in the world? At present I am focusing on fish species diversity in floodplain lakes in the Amazon River Basin, in collaboration with faculty and graduate students at the Federal University of the Amazon (UFAM). The region has a pronounced hydrologic cycle, with forests along rivers that are submerged much of the year. Life cycles of fish species are timed to correspond to flooding and receding waters in these habitats. Floodplain lakes created during low water periods create a potential for metacommunity dynamics and adaptive radiation.
Biodiversity and productivity: The role of predators. Do generalist predators exert top-down control on diversity and productivity of lowe

Abstract
Biological nitrogen fixation, performed by diazotrophic bacteria, plays an important role in the maintenance of agricultural systems, as it contributes with significant amounts of the nitrogen (N) needed for plant growth, totally or partially exempting the use of industrial N fertilisers. Twenty-five bacterial strains isolated from nodules of Leucaena leucocephala and Phaseolus vulgaris trap plants were studied. These nodules were formed after inoculation with suspensions of soil samples collected close to the root system of Sesbania virgata. In previous studies, these bacteria were identified as Cupriavidus necator. This study aimed to evaluate the ability of these strains to fix N2 in the free-living state and to use carbon (C) sources; their resistance to antibiotics; growth in media with different pH values and salt concentrations and symbiotic efficiency with L. leucocephala and P. vulgaris. In each test, these strains were compared to C. taiwanensis LMG 19424T. Although a high variability regarding antibiotic re
