Founded by the Natural History Museum in London, Las Cuevas is a field research station in the Central American country of Belize. The station is tucked away in a remote part of Belize, in the largest remaining rainforest in Central America. The jungle surrounding Las Cuevas is home to scarlet macaws, jaguars, pumas, tarantulas, bats, leaf-cutter ants, and a host of other creatures and plants. ... [Information of the supplier]
Viele Wälder entsprechen heute noch nicht den Grundsätzen der naturnahen Waldwirtschaft. Sie sollen daher nach und nach verändert werden, oder "umgebaut", wie es in der Fachsprache heißt. Der "Waldumbau" ist eines der größten Projekte in der Geschichte der deutschen Forstwirtschaft. Um zu erkunden, wie sich die Wälder im Zuge des Umbaus verändern, welche Probleme und Chancen dabei auftauchen und ob die hoch gesteckten Ziele damit auch erreicht werden können, hat das Bundesministerium für Bildung und Forschung ein Großforschungsprojekt gestartet, das unter dem Namen "Zukunftsorientierte Waldwirtschaft" die Strategien und Auswirkungen des Waldumbaus untersucht hat. Die Ergebnisse dieses Forschungsprojektes sind auf dieser Internetseite dargestellt. ... [Information des Anbieters]
The Forest Ecosystems Research Center (Forschungszentrum Waldökosysteme or FZW) is part of the Forest Faculty of the University of Göttingen and carries out research into structural dynamics and element recycling processes in sylvan ecosystems as well as into the adaptability of forests in the face of environmental change. This includes study of the interaction between the ecosystems and their environment and the new types of forest damage. Last not least, these investigations also lead to an appraisal of commercial feasibility. The aim is to find out under which conditions sustainable forest management is possible. These conditions include natural factors such as climate and soil development as well as human factors such as the use of biomass and atmospheric pollution. Thus the Research Center studies the effects of atmospheric element deposition and forest management on sylvan ecosystems as well as the effects element outflow has on the environment of these ecosystems. An analysis of cause and effect is a condition for establishing critical loads and taking suitable measures for the stabilisation of sylvan ecosystems. Only in this way can detrimental environmental effects - such as on ground water - be avoided and sustainable forest management implemented. The Forest Ecosystems Research Center co-ordinates and integrates a number of different projects on this subject and supports close co-operation with institutions not belonging to the University. Activities include the organisation of conferences and the establishment of contacts with institutes and scientists. ... [Information of the supplier]
Dendrome is a collection of forest tree genome databases and other forest genetic information resources for the international forest genetics community. Dendrome is part of a larger collaborative effort to construct genome databases for major crop and forest species. [Information of the supplier]
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. ...

Tropical ecosystems are the biologically richest places on the planet, yet what we know about them comes from scientific studies so specialized that the results rarely make the local news. “Most ecological studies last fewer than five years at a single study site, with measurements focused on an area of only ten meters squared,” explains Sandy Andelman, Vice President of Conservation International for the Tropical Ecology Assessment and Monitoring (TEAM) Network. “Ecology needs to scale up to address global climate change and other environmental threats.” Scaling up to global proportions is precisely what TEAM was created to do. This ambitious program is devoted to monitoring long-term trends in biodiversity, land cover change, climate and ecosystem services in tropical forests. Tropical forests received first billing because of their overwhelming significance to the global biosphere (e.g., their disproportionately large role in global carbon and energy cycles) and because of the extraordinary threats they face. About 50 percent of the species described on Earth, and an even larger proportion of species not yet described, occur in tropical forests. The idea behind TEAM is deceptively simple: to measure and compare plants, terrestrial mammals, ground-dwelling birds and climate using a standard methodology in a range of tropical forests, from relatively pristine places to those most affected by people. TEAM currently operates in sixteen tropical forest sites across Africa, Asia and Latin America supporting a network of scientists committed to standardized methods of data collection to quantify how plants and animals respond to pressures such as climate change and human encroachment. ...

BIOTREE (BIOdiversity and ecosystem processes in experimental TREE stands) is a long term, manipulative experiment on the role of tree diversity for ecosystem functioning of temperate forests. To our knowledge, the BIOTREE experiment is unique in its size and experimental design, adding value to existing or recently established forest diversity experiments in Finland, Panama and Borneo. ...
