Germinación de semillas de seis especies de Bursera del centro de MéxicoEste artículo evaluó la influencia de la temperatura y el almacenamiento en la germinación de seis especies de Bursera nativas a México (B. bicolor, B. bipinnata, B. cipallifera, B. fagaroides, B. glabrifolia, B. grandifolia). Encontraron alta proporciones de semillas vanas en tres especies. Había un aumento en la germinación dentro de condiciones con una temperatura fluctuante (32-18 °C) en comparación con las semillas expuestos a una temperatura constante (25 °C). No hubo diferencias significativas en la germinación entre las especies con semillas almacenadas durante seis meses a temperatura ambiente y en refrigeración (25 °C). Después de cuatro meses, la germinación de Bursera glabrifolia, B. copallifera y B. bicolor fue del 30 a 60%. Open access copy available |
Facilitation of Forest Landscape Restoration on Abandoned Swidden Fallows in Laos using Mixed-Species Planting and Biochar ApplicationbackgroundThis article aims to assess the feasibility of a plantation with eight mixed native species fertilized with rice husk biochar as a technique for soil amendment at a specific site in Laos. Research Goals & MethodsThe use of biochar was compared to inorganic (NPK) fertilizer and to no fertilization. The effects on the planted seedlings establishment and growth were monitored for four years. Open access copy available |

Nitrogen Dynamics of Actinorhizal Casuarina Forest Stands and its Comparison with Alnus and Leucaena ForestsBackgroundNitrogen plays a key role in soil fertility and plant productivity. Therefore, in regions in which deforestation has increasingly led to savannization and desertification, afforestation by fast-growing, n-fixing tree species is preferable. This study examines the characteristics of nitrogen fixing trees. Research Goals & MethodsThe nitrogen retention rates of three dry tropical forest tree species were measured, by examining rates of N cycling through vegetation, litter and soil pools.

Effects of forest clearing and succession on the carbon and nitrogen content of soils in Puerto Rico and US Virgin IslandsBackgroundConversion of tropical forest lands to agriculture or pasture affects soil organic matter, moisture, and nutrients. This study examines the effects on soil carbon, nitrogen, and moisture at depths up to 100 cm of conversion from forest to agriculture and pasture. Available with subscription or purchase |
