introduction  nowadays, landscape recounts the land components, elements and components which each alone and together have a key role in building and shaping the natural environment and consequently the natural landscape and eventually the built environment and landscape. although humans connection with its surrounding is achieved through different senses, but still more than 80% of its connect...

Landscape genetics, which combines population genetics, landscape ecology and spatial statistics, has emerged recently as a new discipline that can be used to assess how landscape features or environmental variables can influence gene flow and spatial genetic variation. We applied this approach to the invasive plant pathogenic fungus Mycosphaerella fijiensis, which causes black leaf streak dise...

In heterogeneous landscapes, physical barriers and loss of structural connectivity have been shown to reduce gene flow and therefore lead to population structuring. In this study, we assessed the influence of landscape features on population genetic structure and gene flow of a semiaquatic species, the muskrat. A total of 97 muskrats were sampled from three watersheds near Sudbury, Ontario, Can...

Surface water is a primary concept of human experience but concepts are captured in cultures and languages in many different ways. Still, many commonalities exist due to the physical basis of many of the properties and categories. An abstract ontology of surface water features based only on those physical properties of landscape features has the best potential for serving as a foundational doma...

Various features of a landscape contribute to the regulating ecosystem service of reducing waterborne pollutant loading to downstream environments. At local scales, wetlands have been shown to be effective in retaining pollutants. Here, we investigate the landscape-scale contribution to pollutant retention provided by multiple wetlands. We develop a general analytical model which shows that the...

The development of agricultural landscapes during the last decades has been characterized by an increase in management intensity, and a consequent decrease in the number and size of natural and semi-natural habitats. As a result, isolation of populations of stenotopic species of forests, shores, heathers, etc., has increased. This is a serious problem, especially for smaller invertebrates with ...

nowadays, the aims for assessing visual quality of landscape are to define and determine certain criteria and factors that can be used for conservation, rehabilitation and renovation of landscapes as well as determining whether a landscape is aesthetically appropriate or not. by this way, landscapes with aesthetic values are conserved and the rest are amended. analyzing the relations between vi...

as special depositional environments which are adjacent to the seas, deltas have provided a field for human habitat establishment. geomorphic features of deltas are in constant transformation due to their dynamic features. constructing dams on rivers can intensify these changes and cause either negative or positive consequences. minab delta in hormozgan province of iran is a round or crescent-s...
