Choice of Tree Species

Phylogenetic Model Choice: Justifying a Species Tree or Concatenation Analysis

There are two paradigms for the phylogenetic analysis of multi-locus sequence data: one which forces all genes to share the same underlying history, and another that allows genes to follow idiosyncratic patterns of descent from ancestral alleles. The first of these approaches (concatenation) is clearly a simplified model of the actual process of genome evolution while the second (species-tree m...

The introduction of tree and shrub species in the central district of Zanjan county town

Floristic study is one of the most efficient methods of gaining knowledge about biological capacities, as well as management and conservation of plant genetic resources in ecological systems. Zanjan county town is located in a mountainous region with an area of 6763 km2 and the average altitude of 1663 m.a.s.l. Its favorable vegetation diversity is the result of suitable ecological conditions, ...

Choice in ordered-tree-based decision problems

Stochastic Optimization, Tree Structures and Portfolio Choice

Solving realistic dynamic asset allocation problems remains a challenge. While considerable progress with respect to theoretical insights has been made in the past years using dynamic programming, this technique is hardly applicable to deal with industry problems involving numerous sources of uncertainty and path-dependent variables. An alternative solution strategy that has been applied to var...

Object-Based Classification of UltraCamD Imagery for Identification of Tree Species in the Mixed Planted Forest

This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...
