Sustainable forest management integrates ecological, social, and economic objectives. To achieve the former, researchers and practitioners are modifying silvicultural practices based on concepts from successional and landscape ecology to provide a broader array of ecosystem functions than is associated with conventional approaches. One such innovation is disturbance-based management. Under this...

Recent developments in string theory have reinforced the notion that the space of stable supersymmetric and non-supersymmetric string vacua fills out a “landscape” whose features are largely unknown. It is then hoped that progress in extracting phenomenological predictions from string theory — such as correlations between gauge groups, matter representations, potential values of the cosmologica...

In order to strengthen the prediction of rockburst and inquire the relationship between the rockburst proneness of rock and its surface fractal characteristic, the surface fractal of the rock was studied by fractal method and uniaxial compression test. The change rules of surface fractal of different types of rock were compared by calculating its fractal dimension of rock before experiment and ...

Cities present significant opportunities for new landscape perspectives that can help inform conservation and development decisions. Early in the twenty-first century, the majority of the planet’s population became urban as more people lived in city-regions for the first time in our history. As the global population increases, so does this urbanization. The environmental challenges of populatio...

This paper is a contribution to dynamic doxastic logic (DDL), that is, doxastic logic supplemented with operators for belief change due to new information. Thus in addition to operators for belief (B) and doxastic commitment (K) we also have, for each pure Boolean formula φ, a propositional operator [∗φ] with the informal reading “after the agent has come to believe that φ and revised his belie...

The notion of an adaptive landscape has proved to be a valuable concept in theoretical investigations of evolutionary change, combinatorial optimization, and the physics of disordered systems. Landscape theory has emerged as an attempt to devise suitable mathematical structures for describing the \static" properties of landscapes as well as their in uence on the dynamics of adaptation. Here we ...

It has been recognized that urban residential segregation is a scale-dependent phenomenon, and yet all existing structural or spatial indices measure only certain dimensions of segregation at one single scale. Inspired by new metrics developed by landscape ecologists to measure landscape heterogeneity, in this paper we explore the feasiblity of a multiscale, lacunarity-based segregation measure...

Integrated modelling and assessment can facilitate exploration of complex socialeecological interactions and quantify trade-offs in regional policy, planning, and management options. However, there have been challenges in its acceptance and adoption for supporting decisions. Here we overcome this implementation gap through the development of an interactive online tool called the Landscape Futur...

The gradient based landscape metrics analysis is now widely used to study the landscape pattern change in respond to urbanization. In order to discover the Beijing metropolitan area landscape pattern spatial and temporal change trends during the past 15 years, several landscape metrics are computed along a 96 km long transect crossing Beijing metropolitan area from west to east. Specially, the ...

Analytical models show that high-dimensional fitness landscapes form “holey” rather than “rugged” topographies, but the implications of this finding for biological and artificial life systems remain largely unexplored. One of the reasons for this gap can be attributed to serious difficulties in the implementation of individual-based holey fitness landscape (HFL) models. Here, we introduce a met...
