Wildfire mitigation strategies affect soil enzyme activity and soil organic carbon in loblolly pine (Pinus taeda) forests
We quantified the effects of three wildfire hazard reduction treatments (prescribed fire, thinning from below, and the combination of fire and thinning), and passive management (control) on mineral soil organic C, and enzyme activity in loblolly pine (Pinus taeda L.) forests on the Piedmont of South Carolina. Soil organic C was reduced by thinning, either alone or with prescribed fire, and this...
متن کاملUrbanization in China drives soil acidification of Pinus massoniana forests
Soil acidification instead of alkalization has become a new environmental issue caused by urbanization. However, it remains unclear the characters and main contributors of this acidification. We investigated the effects of an urbanization gradient on soil acidity of Pinus massoniana forests in Pearl River Delta, South China. The soil pH of pine forests at 20-cm depth had significantly positive ...
متن کاملEffects of sedimentation on soil nutrient dynamics in riparian forests.
The influence of sedimentation rates on biogeochemistry of riparian forests was studied near ephemeral streams at Fort Benning, GA. Upper reaches of seven ephemeral streams had received varying rates of sedimentation stemming from erosion along unpaved roadways at the military installation. Two reference catchments were also included in the study. Decomposition of foliar litter, microbial C and...
متن کاملSoil Nutrient Composition in Afromontane Forests of Northern Ethiopia
Deforestation in the northern highlands of Ethiopia has left 35,000 forest fragments ranging in size from 3 to 300 ha (Bongers et al 2006). Deforestation produces edges which increase disturbance within the forest such as decreased water availability and increased light. To determine the degree of these edge effects and the nutrient status of these forests, I analyzed the nutrient composition o...
متن کاملThe Effect of Altitude on the Pattern of Gene Flow in the Endemic Canary Island Pine, Pinus canariensis
Pinus canariensis is endemic to the western Canary Islands (NW coast of Africa), where it forms forest spanning an altitude from 500 to 2500 m. There are dramatic changes in environmental conditions (temperature, moisture and solar radiation) over short distances due to this elevation gradient in the Canary Island pine forest. Those differences in environmental conditions may lead to asynchrono...
