El aumento de la deforestación en la cuenca del río Madre de Dios, Amazonía peruana, incrementaría la escorrentía superficial y la concentración de sedimento

Background

En la Amazonía sudeste del Perú, se encuentra la cuenca del río Madre de Dios, uno de los focos de biodiversidad mundial. Sin embargo, la alta tasa de deforestación en la cuenca del río Madre de Dios genera una gran preocupación pues la cobertura vegetal es de vital importancia en la conservación de los ríos y suelos. En ausencia de la cobertura vegetal, la precipitación impacta directamente en el suelo y la cantidad de agua que no puede ser infiltrada discurre a través de arroyos definidos por la topografía de la cuenca.

Influencia de la minería aurífera aluvial en la geodinámica fluvial del río Madre de Dios, Amazonía peruana, en el periodo 1984-2020

Background:

La dinamica de la rios es escencial en mantener la extraordinaria biodiversidad de los bosques tropicales. Sin embargo en la Amazonia de Madre de Dios (Peru) estos rios estan siendo fuertemente impactados por la mineria artesanal de oro, que hasta la fecha ha deforestado mas de 100 000 ha de bosque amazonico. La mineria aluvial es de especial preocupacion pues puede alterar la dinámica fluvial natural de los ríos al modificar el ancho, la profundidad, la sinuosidad y la estabilidad del canal.

Divergent litterfall nutrient responses to rainfall seasonality revealed through long-term observations in a tropical dry forest

Background

Forest 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.

Drought reduces the growth and health of tropical rainforest understory plants

Background

Plant 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.

Growing biodiverse carbon-rich forests

Background

Carbon 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.

Riparian restortion for protecting water quality in tropic agricultural watersheds

Background

In 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, China

Background

Throughout 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.
