Though competition operates distinctly above and below ground, competition with near neighbours explained more variation in crown and root system morphology of young tropical trees than did abiotic conditions. Comparisons of above- and below-ground t

A pressing question is whether biodiversity can buffer ecosystem functioning against extreme climate events. However, biodiversity loss is expected to occur due to climate change with severe impacts to tropical forests. Using data from a ca. 15 year-

We examined changes in soil organic matter arising from conversion of a 45-year old pasture to a 10 yr. old native tree plantation in Panama, to evaluate the effect of monoculture and mixtures. We intensively sampled the soil 0–10 cm depth in the p

Reducing carbon emissions from deforestation and forest degradation (REDD+) has become central to efforts to mitigate climate change. Approximately 10 % of the world’s forests are managed by local and indigenous peoples. Agroforestry may provide th

Uncertainty in emissions and emission changes estimates constitutes an unresolved issue for a future international climate agreement. Uncertainty can be addressed ‘upstream’ through improvements in the technologies or techniques used to measure,

Mixed plantations might contribute to sus- tainable land use because of complementary nutrient use. Our objective was to assess the nutrient economy of five native tree species and their response to different neighbor trees in an experimental plantat

This paper is part of a two-year study to investigate the feasibility of initiating a Clean Development Mechanism (CDM) project in an indigenous com- munity of Eastern Panama ´ , Ipeto´-Embera ´ . We use participatory mapping and matrices as well

The horned grebe (Podiceps auritus) population of the Magdalen Islands in the St. Lawrence Gulf (Quebec, Canada) has declined sharply over the last decades. It is the only breeding population of this species in eastern North America with nearest bree

This paper examines changes in carbon (C) pools associated with land-use, synthesizing data from two experiments dealing with different aspects of tree plantation establishment in Central Panama. First, we analysed soil profiles in a grazed pasture a

On both theoretical and practical grounds, respect for, and inclusion of, local decision-making processes is advocated in conservation, yet little is known about the conservation priorities on local territories. We employed interviews and ecological
