Divergent litterfall nutrient responses to rainfall seasonality revealed through long-term observations in a tropical dry forestBackgroundForest litterfall can provide important nutrients to the soil for ecosystem health such as Phosphorus and Nitrogen. In water limited ecosystems rainfall often controls forest nutrient cycling. It is not yet understood how nutrient uptake of these nutrients is influenced by seasonal rainfall and how these litter nutrient contents change from year to year. Open access copy available |
Drought reduces the growth and health of tropical rainforest understory plantsBackgroundPlant responses to drought are important to understand for agricultural practices and environmental stress. Susceptibility to drought varies among and between plant species. Most field studies on plant responses to drought in tropical rainforests ignore understory plant species such as saplings and shrubs. These species are important to understand because they are often more vulnerable to environmental stressors, and they contribute greatly to forest biodiversity. Open access copy available |

Growing biodiverse carbon-rich forestsBackgroundCarbon storage and biodiversity has long been viewed as completely separate restoration objectives, resulting in parceling tracts of restoration land for one objective or the other. This study shows that the relationship between plant functional diversity and carbon sequestration rate depends on climate and habitat factors. Knowing this relationship, a restoration site can be managed for both objectives. Open access copy available |
Riparian restortion for protecting water quality in tropic agricultural watershedsBackgroundIn the Sarapui River watershed in southeastern Brazil, the water quality system was measured for six subwatersheds in the region. In addition to measuring the subwatersheds, the entire watershed system was also measured and compared to a simulation model that included riparian zones throughout the river watershed.

Evaluating the ecological performance of wetland restoration in the Yellow River Delta, ChinaBackgroundThroughout the world, wetlands have been severly degraded. In response, there have been large scale efforts to restore these vital ecosystems through focusing on three key areas: hydrology, biology and soil. Still, there are significant knowledge gaps concerning these efforts. Thus, this monitoring project evaluates the progress of wetland restoration in an area in the Yellow River Delta in China in order to further develop, refine, and disseminate site and landscape-level monitoring methods and trail restoration processes.

The Transformation of a Frontier: State and Regional Relationships in Panama, 1972- 1990BackgroundFollowing the trend of anthropologists that examine the settlement of frontier regions, this study describes the consequences of building the Bayano Hydroelectric Complex in eastern Panama. The authors stress that governments must not looked at as monolithic entities but instead should be examine as a set of social and political relationships among various stakeholders at local, national, and international scales. Along with documenting the social, political, and ecological effects that emerged from the dam, the study also describes the internal conflicts between agencies in the Panamanian government.

The Effect of Deforestation on Water Quality: A Case Study in Cienda Micro Watershed, Leyte, PhilippinesbackgrouNdForests and water are important resources that provide both socioeconomic and ecological benefits. They also are connected, meaning that deforestation has a negative impact on the quality of water flowing through a watershed. This paper seeks to present the detailed effects and relationship between deforestation and water quality. Open access copy available |
