Web10 de fev. de 2024 · Compared to the equilibrium and non-equilibrium paradigms, the changes that occur at multiple spatial scales are better explained by the hierarchy theory and the hierarchical patch dynamics paradigm, which suggest that for this specific reason, forest landscapes consist of nested but discernible hierarchical patches at … Web24 de ago. de 2007 · 1 . Patch dynamics is a new, potentially unifying mechanism for the explanation of tree-grass coexistence in savannas. In this scale-explicit paradigm, savannas consist of patches in which a cyclical succession between woody and grassy dominance proceeds spatially asynchronously.

WebIn this paper, we apply a dynamically integrated “hierarchical patch dynamics paradigm (HPDP)” to model detailed near-well dynamics and interactions. The HPDP enables converting a large, complex problem into a network of hierarchically nested and dynamically coupled patch models that can be easily solved. can army doctors go to ranger school
