15 صفحه اولRethinking Tropical Forest Conservation: Perils in Parks
Large, pristine, uninhabited parks are the defining criterion of success in conserving tropical forests, according to some conservationists. It is argued that human residents in tropical forests inevitably deplete populations of large animals through hunting, triggering a chain reaction of ecological events that greatly diminish the conservation value of these forests. Hence, the removal of peo...
متن کاملDistribution of radionuclide in the forest soils (Western Ghats-India)
Background: The presence of radionuclides in the soil, measures need to be taken to minimize the radiation dose to humans. It is mostly gamma-emitting radionuclides that contribute to the radiation dose in long term behavior of these radionuclides in soil may determine the extent to which such countermeasures need to be applied. Materials and Methods: The activity concentration of these radionu...

متن کاملTranspiration and CO2 fluxes of a pine forest: modelling the undergrowth effect
A modelling study is performed in order to quantify the relative effect of allowing for the physiological properties of an undergrowth grass sward on total canopy water and carbon fluxes of the Le-Bray forest (Les-Landes, Southwestern France). The Le-Bray forest consists of maritime pine and an herbaceous undergrowth (purple moor-grass), which is characterised by a low stomatal control of trans...
