Alencar conducts research on biodiversity and the importance of sustainable
forest development in the floodplain forest of the Central Amazon. Some
of her work includes working toward a better understanding of fruit production
(as related to the food web and fishery stock maintenance); tree phenology;
tree CO2 assimilation; and seed dispersion by fish and water.
Forsyth is the President and co-founder of the Amazon Conservation Association,
a non-profit organization working to conserve the biological diversity
of the Amazon Basin through development of new scientific understanding,
sustainable resource management, and rational land-use policy for Amazonian
ecosystems. Adrain holds a PhD from Harvard in tropical ecology and has
20 years of conservation experience in the Amazon region. He has worked
as Vice President of Conservation International and is currently a Research
Associate at the Smithsonian Institution and Director of Biodiversity
Science for the Gordon & Betty Moore Foundation.
Keller studies the effects of land use change and agricultural intensification
in Central and South America on the function of ecosystems and the control
of atmospheric chemistry and composition. His research ranges from the
biological controls of trace gas emissions at the organismal level to
the estimation and modeling of regional and global trace gas and carbon
budgets. Over the past two decades, he has lived and worked in Brazil,
Panama, Costa Rica, and Puerto Rico as well as in the United States. He
currently serves as lead scientist for the NASA sponsored LBA-ECO component
of the Brazilian led Large Scale Biosphere Atmosphere in Amazonia (LBA)
and the Co-Chair of the LBA International Science Steering Committee.
LBA-Ecology is designed around the question "How do tropical forest
conversion, regrowth, and selective logging influence carbon storage,
nutrient dynamics, trace gas fluxes and the prospect for sustainable land
use in the Amazon region?" In order to answer this question together
with his colleagues in LBA-ECO, he combines in situ measurements with
regional models and remotely sensed observations of biological and social
systems in the Amazonian environment. For more information on LBA, consult
Laurance is a research scientist at the Smithsonian Tropical Research
Institute who is interested in assessing the impacts of intensive land-uses,
such as habitat fragmentation, logging, and fire, on tropical ecosytems.
He also studies the effects of global-change phenomena on tropical ecosystems,
and forest-conservation policy. He has worked extensively in the Brazilian
Amazon and tropical Australia, and also has conducted field studies in
New Guinea, Southeast Asia, and Central America. He received his Ph.D.
in 1989 from the University of California, Berkeley.
Professor in the Department of Ecology, Evolution and Marine Biology at
the University of California - Santa Barbara, John Melack has a research
program in limnology, biogeochemistry, aquatic ecology and remote sensing
with active studies in the Amazon of Brazil, and coastal wetlands and
streams and alpine and saline lakes in California. He has published over
180 scientific papers, edited two books and a special issue of Limnology
and Oceanography, written 12 book reviews and prepared 30 technical, workshop
or committee reports. He has represented the limnological community on
NASA's Science Steering Committee for the Earth Observing System. He served
on the National Academy of Sciences committee that prepared The Mono Basin
Ecosystem-Effects of Changing Lake Level, and on three NSF working groups
that assessed the status and future of research on large lakes, community
ecology of lakes, and stream processes. Currently, he is a member of the
National Academy of Sciences Committee on Geophysical and Environmental
Data and the Board of Directors of the American Society of Limnology and
Adriana Moreira is a Senior Environmental Specialist for the World Bank in Brazil, working most recently on the Pilot Program to Conserve the Brazilian Rain Forest. This program is a joint undertaking of the Brazilian government, Brazil's civil society, and the international community that seeks to find ways to conserve the tropical rain forests of the Amazon and Brazil's Atlantic coast. For the program, to "conserve" means both to protect the forests and to promote sustainable development in these regions - to meet the needs of the current generation without compromising the needs of future generations.
The Brazilian rain forests offer significant environmental benefits to Brazil and to the world. The forests harbor a rich diversity of plants and animals, store carbon that if released would contribute to the greenhouse gases in the atmosphere, regulate water cycles, and preserve the region's humid climate.
Brazil also has a legitimate interest in using this natural resource for the economic opportunities it represents to the people who live in the forests and to Brazil as a nation.
the goal of the program is to maximize the environmental benefits of the
forests in a way that is consistent with the development goals of Brazil
and its people . The Program is a unique example of countries working
together effectively to solve an international problem involving the global
Nepstad, a Senior Scientist at the Woods Hole Research Center, works to
assess the ecological impacts of land use in the Brazilian Amazon and
developing strategies for reversing these impacts through restoration
of forest cover and agricultural productivity on degraded land. His research
includes analyzing the importance of deep-rooting in Amazonian forests
and the changes in deep-soil processes, such as carbon storage and water
uptake, that accompany different land uses. Prior to joining the Center,
Dr. Nepstad worked with the National Wildlife Federation's international
program in Washington, DC. His doctorate in forest ecology is from Yale
University. He is a 1994 Pew Scholar in Conservation and the Environment.
Powell is a senior scientist at the World Wildlife Fund - US, with a long
history of rainforest research in the Amazon and elsewhere. Current research
foci include the effects of human activity on the Amazon forest and inhabitants,
as well as the forest's influence on regional and global climate.
