coal mine drainage in Appalachia have polluted an estimate 17,000 km of streams. In addition to these chemical disturbances, road building, mine site construction and strip mining have impaired the physical habitat of streams adjacent to mining sites through channelization or sedimentation. The combined effect of chemical and physical stressors on stream
The CarajaÂs National Forest contains some of the largest iron ore deposits in the world. The majority of the minerals are found below a plant community known as Savana Metalo fila, or ªCangaº, which represents only 3% of the landscape within the CarajaÂs National Forest (CNF). The aim of our study was to understand the diversity of community of nonvolant small mammals in the two ...
