The neotropical palm Euterpeprecatoria is subject to extraction for its valuable palm heart. The development of management and conservation practices for this species requires understanding of its population structure, dynamics, and traditional use across the range of environments it inhabits, from different successional stages in continuous forest to forest fragments. Here, we analyzed how the...

Our goal is to model and simulate forest dynamics in order to observe large-scale characteristics of the forest as they emerge from local competitive interplay among individuals. This objective can be reached by developing a spatial gap model. Spatialisation can be achieved from a spaceor individual-oriented perspective. Because the choice of one approach over the other leads to consequences af...

29 2 Suresh Dara, S.M. Hegde, V. Deva, S.B. Rao and T. Zaslavsky In 1966, Cummins introduced the “tree graph”: the tree graph T(G) 30 of a graph G (possibly infinite) has all its spanning trees as vertices, and 31 distinct such trees correspond to adjacent vertices if they differ in just one 32 edge, i.e., two spanning trees T1 and T2 are adjacent if T2 = T1 − e+ f for 33 some edges e ∈ T1 and ...

Many defoliating forest lepidopterans cause predictable periodic deforestation. Several of these species exhibit geographical variation in both the strength of periodic behavior and the frequency of cycles. The mathematical models used to describe the population dynamics of such species commonly predict that gradual variation in the underlying ecological mechanisms may lead to punctuated (subha...

Forest conversion for agriculture expansion is the most salient signature of human occupation of the earth's land surface. Although population growth and deforestation are significantly associated at the global and regional scales, evidence for population links to deforestation at micro-scales-where people are actually clearing0020forests-is scant. Much of the planet's forest elimination is pro...

By Francis A. Roesch and Gregorv A. Reams Y I The USDA Forest Service Southern Research Station (SRS) Forest Inventory and Analysis Unit (FIA) has initiated an annualized forest inventory sampling des@, the Southern Annual Forest Inventory System (SAFIS). SAFIS was introduced to improve estimation of both the current resource inventory and changes in the resource. Under the previous periodic in...
