introduction this study is dealt with the environmental planning from a bio-cybernetic and hierarchical systems viewpoint within the context of landscape ecology. this viewpoint requires not only knowledge of the science of ecology but also ecological wisdom in order to recognize the place of humankind in nature. the conceptual and practical approach which is provided will help landscape planne...

Stressful life and reduced well-being have always been an issue of lifestyle in modern society. Constructing a multidisciplinary conceptual framework of environmental tranquility and quality of life is required for the field of architectural development, improved environmental quality, and enhanced human well-being. This paper reviews the main concepts of tranquility, environmental quality, and...

The watershed approach, currently used to assess regional streams in the United States, emphasizes least-disturbed reference conditions. Consideration of extensive wadable drainage systems found in Arkansas and Mississippi deltas challenges concepts of disturbance within a landscape of historic agricultural land use. Seventeen wadable drainage ditch sites in Arkansas and Mississippi deltas were...

We show that the various crossovers between dynamical regimes observed in experiments and simulations of supercooled liquids can be explained in simple terms from the existence and statistical properties of dynamical heterogeneities. We confirm that dynamic heterogeneity is responsible for the slowing down of glass formers at temperatures well above the dynamic singularity Tc predicted by mode-...

The Arctic Coastal Plain (ACP) of northern Alaska consists of an extremely low gradient, lake-rich landscape that is characterized by a complex network of aquatic habitats and surface features strongly influenced by permafrost dynamics. Much is unknown about the form, function, and ecological conditions in this unique hydrologic setting. Amplified climate change and landscape responses in the A...

This paper presents an analysis of ethnographic observations of two landscape architects’ interactions with objects as they are working on the design of an urban square. Physical samples of bricks, as well as visualisations are an integral part of the work. Objects like these are an important resource for the formation, development, and communication of design ideas. Yet the ways in which they ...

The oxygen and silicon dynamics in silica are compared via computer simulations. In agreement with experimental data and previous simulations a decoupling of oxygen and silicon dynamics is observed upon cooling. The origin of this decoupling is studied in the framework of the potential energy landscape. From analysis of the transition features between neighboring superstructures of minima, deno...

This paper presents the first fitness landscape analysis on the delay-constrained least-cost multicast routing problem (DCLC-MRP), a well-known NP-hard problem. Although the problem has attracted an increasing research attention over the past decade in telecommunications and operational research, little research has been conducted to analyze the features of its underlying landscape. Two of the ...

Amphibians are often considered excellent environmental indicator species. Natural and man-made landscape features are known to form effective genetic barriers to amphibian populations; however, amphibians with different characteristics may have different species-landscape interaction patterns. We conducted a comparative landscape genetic analysis of two closely related syntopic frog species fr...

Small mammals provide ecosystem services, acting, for example, as pollinators and seed dispersers. In addition, they are also disease reservoirs that can be detrimental to human health and they can also act as crop pests. Knowledge of their dispersal preferences is therefore useful for population management and landscape planning. Genetic data were used alongside landscape data to examine the i...
