Biodiversity conservation in community forests of Nepal: Rhetoric and reality

  Community forests management in Nepal has been exemplified as one of the most successful programs for participatory resource management. The success of community forestry is described in terms of restoring degraded land and habitats, conserving biodiversity, increasing supply of forest products, empowering women and disadvantaged groups, generating rural incomes, and developing human resources. However, the...

Enrichment planting of an understory palm: Effect of micro-environmental factors on seedling establishment, growth, and survival

  Although extraction of non-timber forest products (NTFPs) is considered an ecologically sustainable source of income, NTFP populations are vulnerable to depletion. The community of Alta Cima in the El Cielo Biosphere Reserve in Tamaulipas, Mexico, has conducted enrichment plantings of Chamaedorea radicalis, an important NTFP in northeastern Mexico, in forest areas near the village to supplement wild...

Variation of turbulent mixing parameters at the Egyptian Mediterranean coast

  The analysis of the turbulent mixing structure is accomplished by the dynamical computations of the mixing parameters represented by: buoyancy frequency (N), viscous dissipation (ε), turbulent kinetic energy (E), Richardson number (Ri), Reynolds stress, diffusive salt flux (DSF), diffusive heat flux (DHF). In general the computations show that, the water column becomes more stable and less stratified...

Haematological studies of Oreochromis niloticus exposed to diesel and drilling fluid in Lagos, Nigeria

  Haematological changes in Oreochromis niloticus after exposure to diesel (23.4 mg/L) and drilling fluid (492 mg/L) for 28 days was investigated. The blood parameters of O. niloticusrevealed a significant decrease in haemoglobin only in fish exposed to drilling fluid and mean cellular volume (MCV), in both diesel and drilling fluid. Blood parameters of the fish such as mean cellular haemoglobin (MCH)...
