Ecosystem Health and Its Measurement at Landscape Scale: Toward the Next Generation of Quantitative Assessments
2001
Ecosystem health
Preserved Fulltext
The purpose of this paper is twofold: (A) to describe the challenges of reporting on changes in ecosystem health at landscape scales, and (B) to review the statistical and mathematical techniques that ...
HIERARCHICAL STRUCTURE ANALYSIS Trees and other nodal graph structures arise in the map modeling, echelons, and poset components of MARMAP. Also important is the coupling of related structures. ...
First, model fitting provides a set of estimated parameter values characterizing the spatial structure of the map (landscape). ...

The minimum barrier (MB) distance is defined as the minimal interval of gray-level values in an image along a path between two points, where the image is considered as a vertex-valued graph. ...
In this paper, based on the discrete set-valued continuity setting, we present a new discrete definition for this distance, which is compatible with this interpretation, while being free from digital topology ...

The inferred mutational networks for subtype B versus C are significantly different sharing only five constraints on the order of accumulating mutations with mutation at residue 54 as the parental event ...
In other comparative studies using data simulated under various fitness landscapes, H-CBN models typically provide comparable or better performance to competitors such as CAPRI [33] and trees [33, 34 ...

Multiparameter persistence has become one of the most active areas of research within TDA, with exciting progress on several fronts. ...
In topological data analysis (TDA), one often studies the shape of data by constructing a filtered topological space, whose structure is then examined using persistent homology. ...

The lower bound by Linial (1987 Linial ( , 1992 shows that the dependency on n is optimal: these problems cannot be solved in o(log * n) rounds even if ∆ = 2. ...
However, the dependency on ∆ is a long-standing open question, and there is currently an exponential gap between the upper and lower bounds. We prove that the upper bounds are tight. ...
Acknowledgments We would like to thank Mohsen Ghaffari for pointing out that the randomized lower bound implies a better deterministic lower bound, and Seth Pettie for pointing out that the bound is tight for trees ...
