Forest Ecosystems: Nutrient Cycling
Nutrients are elements or compounds that are essential for the growth and survival of plants. Plants require large amounts of nutrients such as nitrogen (N), phosphorus (P), carbon (C), hydrogen (H), oxygen (O), potassium (K), calcium (Ca), and magnesium (Mg), but only small amounts of others such as boron (B), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn) and chlorine (Cl) (micronutrients)...
متن کاملSession Overview: Forest Ecosystems
The core assumption of this symposium is that science can provide insight to management. Nowhere is this link more formally established than in regard to the science and management of forest ecosystems. The basic questions addressed are integral to our understanding of nature; the applications of this understanding are crucial to effective stewardship of natural resources (Carpenter and Turner ...
متن کاملDeadwood in Forest Ecosystems
Until recently, deadwood was perceived as a negative element of forest ecosystems, that indicates “mismanagement, negligence, and wastefulness” of the applied forest management (Stachura et al., 2007). It was regarded as a potential source of biotic pests, mainly insects (Bütler, 2003; Marage & Lemperiere, 2005), to remaining trees in a forest as well as to adjacent stands (Pasierbek et al., 20...
متن کاملRelighting Forest Ecosystems
Real-time cinematic relighting of large, forest ecosystems remains a challenging problem, in that important global illumination effects, such as leaf transparency and inter-object light scattering, are difficult to capture, given tight timing constraints and scenes that typically contain hundreds of millions of primitives. A solution that is based on a lattice-Boltzmann method is suggested. Ref...
متن کاملModelling forest ecosystems: the Edinburgh Forest Model
Reasons for building an ecosystem model are discussed, stressing the importance of objectives. A model is required for any research programme aiming to take a firm grasp of forest responses. The Edinburgh Forest Model (EFM) is outlined. This is a standard model of the genre, taking account of pools and fluxes of carbon (C), nitrogen (N) and water. It comprises tree, soil and water submodels. Th...
