In the lowland tropical rain forest of central Amazonia, I investigated the responses of understory bird communities to forest edges bordering a narrow (<40 m width), unpaved road. From 3681 mist-net captures, bird abundance and composition were examined at three distances (10, 70, and 130 m) from forest edge. The degree to which regrowth vegetation along forest borders reduced edge effects was...

Roads and traffic can cause animal mortality. Specifically, roads serve as barriers by impeding movement, resulting in demographic genetic consequences. Drainage structures, such culverts, provide linkages between habitat patches. However, the potential of small culverts with diameters &lt;60 cm (e.g., wildlife passages that facilitate movement on forest roads) are relatively unknown. In this s...

The Water Erosion Prediction Project (WEPP) model is a physically-based soil erosion tool developed to predict runoff and erosion. Databases for forest soil, vegetation, and climate conditions have been developed. Background sediment may be generated annually from undisturbed forests, and occasionally following wildfire. In some cases, it may be appropriate to include sediment from essential fo...

This study aims to predict the spatial distribution of tropical deforestation. Landsat images dated 1974, 1986 and 1991 were classified in order to generate digital deforestation maps which locate deforestation and forest persistence areas. The deforestation maps were overlaid with various spatial variables such as the proximity to roads and to settlements, forest fragmentation, elevation, slop...

(eds.), Sustaining Young Forest Communities, Managing Forest Ecosystems 21, DOI 10.1007/978-94-007-1620-9_14, © US Government 2011 Abstract Tree harvests that create early successional habitats have direct and indirect impacts on water resources in forests of the Central Hardwood Region. Streamflow increases substantially immediately after timber harvest, but increases dec...
