Ecological models with species differentiated by competition and colonization traits analyze landscape patterns in two phases (habitat and nonhabitat). The consequences of representing landscape patterns as a continuous surface of habitat quality
The coastal Namib Desert is characterized by low habitat diversity, low primary productivity and adverse climatic conditions and therefore few primary consumers (Herbivores). - (AJC)
The A. discusses the application of landscape ecological principles to a specific and pressing issue: nature reserve design and functioning. He reviews 5 landscape ecological themes with relevance to reserve design and management. He studies
: the role that landscape ecological theories may have in integrating existing principles from applied biogeography and population biology; the unique insights provided by a landscape ecological approach. Finally, he argues that biogeographers need to be more
active in the development and advancement of landscape ecological theory.

; the vegetation types were based on vegetation within 50 m of the sample points. Nonparametric multivariate statistical tests showed that both ecological units and vegetation types provide useful and complementary information about bird habitat selection
Point-count data from the bird inventory were used to test the ability of the ecological units to fine-scale vegetation types. The ecological units were a synthesis of geology, landforms, soils, and vegetation mapped at a scale of 1:250,000
. Ecological units have several advantages over vegetation types as sample-area strata.
The A. reviews the mainstream ecological literature from 1994 to 1995 to gauge the importance of ecophysiological studies in understanding the ecology of tropical rain forests.
This review considers the development of wall ecology, highlighting the key characteristics of walls that have been found to influence their ability to support species, with a focus on higher plants. It then examines the kinds of plant assemblages
that are found on walls and the broader role of walls within urban biodiversity, before discussing the potential for ecological engineering of walls. Some progress has recently been made in the latter area with the installation of living walls and the physical
engineering of wall materials, but much more needs to be done to effectively increase their physical complexity and habitat quality. Walls therefore represent a substantial potential (as well as existing) habitat within urban areas.
This paper describes the habitats used by migrant species at a migratory stop-over site in an urban wooded environment in Georgia. The diversity of habitat use by migrating and resident species will be compared, as well as the degree to which

The concept of geomorphological sensitivity provides a useful starting point for identifying sensitive upland landscapes. This paper develops a geo-ecological pespective which unites both habitat and ecological dependencies in fragile upland
Cet article décrit les défis (dans les domaines théorique et pratique) à affronter, pour comprendre les détails des conditions de l'habitat physique dans les chenaux fluviatiles. Un certain nombre d'approches à échelle méso apparaissent, à la fois
This paper begins with definitions of the basic concepts and relevant terms, continues with a review of remote sensing in habitat mapping projects and common information extraction techniques, and concludes with the description of a framework
this of the processes in the ecology of the landscape which change these habitats. The results of this study can be applied to restoration projects, if desired target situation is defined. The technical and sustainable measures for restoration have to be incorporated
The relation between hydrology aznd vegetation in the Dutch man-made aquatic polder ecosystems has been investigated at two scales : first this of the direct habitat relations between species and the values of non-biotic variables, and secondly

The larval form of the fox tapeworm, Echinococcus multilocularis, causes a fatal liver infection in human and has high prevalence in western China. This paper introduces the tapeworm and reviews the current understanding of its transmission ecology
in relation to each component of its lifecycle. Recent research indicates that landscape plays an important role in creating the necessary habitat conditions for natural transmission. Defining the landscape involves the use of satellites imagery, land cover
classification and spatial analysis. The link between desease, remote sensing and landscape ecology is an expanding research area.
quality variables were also measured. High light penetration was noticed during the winter and spring. Seasonal variations were clear in the total cell numbers of algae from different habitats.
In the late 1970s, a concept of an ecological network in former Czechoslovakia, called the Territorial System of Ecological Stability (TSES) was formulated as a response to large-scale natural and semi-natural habitat fragmentation and loss
. In the Czech Republic, the TSES concept is a part of the environmental legislation. The whole system is the network of ecologically significant segments of landscape, efficiently distributed on the basis of functional and spatial criteria, covering biotic
The hydromorphological and sedimentological characteristics of spawning habitats of Atlantic salmon and sea trout were studied in selected rivers in Northern and Western Germany some 30 years after the initiation of restocking measures
This paper evaluates the recent use of remote sensing in landscape ecology. First, to provide an overview of current practice, 438 research papers published in the journal Landscape Ecology for the years 2004—2008 were examined for information about
use of remote sensing. Selected case studies are then presented that illustrate the potential value of using diverse remote sensing data together with ecological field data, as an integrated approach to landscape ecology research. Finally, the future
development of landscape ecology as a predictive scientific discipline is considered, with particular reference to the potential role of remote sensing.
