The Amazon Forest Inventory Network is an international network that has been established to understand the biomass and dynamics of Amazonian forests. Since 2000 we have established a systematic framework for long-term monitoring of this region, which holds more biodiversity, water, and vegetation carbon, than any other region of the planet. RAINFOR has worked step-by-step, including partners across the nations of Amazon, taking account of the potentially strong modulating role of environmental variables like soil nutrition, and the need to help develop a new generation of Amazon ecologists. RAINFOR is curently supported by the Andes and Amazon Initiative of the Gordon and Betty Moore Foundation. ... [Information of the supplier]
Tropical forests harbour thousands of useful plants that are harvested and used in subsistence economies or traded in local, regional or international markets. The effect on the ecosystem is little known, and the forests resilience is badly understood. Palms are the most useful group of plants in tropical American forests and in this project we study the effect of extraction and trade of palms on forest in the western Amazon, the Andes and the Pacific lowlands. We determine the size of the resource by making palm community studies in the different forest formations and determine the number of species and individuals of all palm species. The genetic structure of useful palm species is studied to determine how much harvesting of the species contributes to genetic erosion of its populations, and whether extraction can be made without harm. We determine how much palms are used for subsistence purposes by carrying out quantitative, ethnobotanical research in different forest types and we also study trade patterns for palm products from local markets to markets that involve export to other countries and continents. Palm populations are managed in various ways from sustainable ones to destructive harvesting; we study different ways in which palms are managed and we will propose sustainable methods to local farmers, local governments, NGOs and other interested parties. Finally we study national level mechanism that governs extraction, trade and commercialization of palm products, to identify positive and negative policies in relation to resilience of ecosystems and use this to propose sustainable policies to the governments. ...

The primary aim of the Victorian Rainforest Network (VRN) is to secure the effective conservation of rainforests on public land throughout Victoria by ensuring rainforests are adequately identified and protected from logging practices by appropriate buffers and/or permanent reservation. VRN is an independent and politically unaligned network of rainforest enthusiasts, researchers and activists with a shared interest in rainforest conservation and education across Victoria. VRN is simply asking Government to follow their own rules. ... [Information of the supplier]
The Amazon Tree Diversity Network is an electronic network of 143 botanists, ecologists and taxonomists that share data and information on tree diversity in the pan-Amazon (Amazonia s.s. and the Guyana Shield). Our drive is to gain a better understanding of the processes that drive (patterns of) alfa- and beta-diversity in the region and, through this knowledge, contribute to better conservation strategies for the region. Currently we work with data from botanical 1-ha plots (and sometimes different sizes), forest inventories, and herbarium collections. In 2003 the work of ATDN resulted the first accurate and robust map of tree alpha-diversity of the Amazon. We unravelled relationships between climate and diversity. The combination of the above results and use of functional groups, successfully tried in some of our Guyana plots, and now also in the Amazon, can perhaps help us to predict the effect of global change in these important and beautiful forests. ...

The aims of the project are related to the understanding of diversity and ecosystem function and their relationship to human impact in forests and agroforestry systems of the Mata Atlântica in Paraná State, Brazil. General goals in this ecosystem approach are: 1.)to monitor ecosystem functionality and services in terms of biomass deposition and decomposition, nutrient cycling and forest succession including botany and soil microbiology at a functional level (tree growth, microbial biomass and activity),2.)to assess the diversity of soil biota in different habitats, estimate the magnitude of species richness and species loss and changes in community structure caused by anthropogenic alteration of the environment, and 3.)to develop a classification system indicating the quality of secondary forests in the southern Mata Atlântica as habitat for autochthonous (soil invertebrate) species. The investigation is considered a case study for the whole biome. ... [Information of the supplier]
