Landscape structure is a main determinant of ecological landscape potentials. The basic differentiation of relief into depressions and elevations at deliberately chosen scales can be managed comfortably by the Fourier transformation. The automated extraction of these structures from an elevation map using Fourier transformation or singular value decomposition can help to overcome complicated an...
Since landscape attributes show different patterns at different spatial extents, it is fundamental to identify how the relation between landscape structure and plant species diversity at local scale varies with scale. Then, it is fundamental to assess the appropriate extent at which landscape factors affect plant species richness at the local scale. To investigate this relation, data on plant s...
Seasonality causes fluctuations in resource availability, affecting the presence and abundance of animal species. The impacts of these oscillations on wildlife populations can be exacerbated by habitat fragmentation. We assessed differences in bat species abundance between the wet and dry season in a fragmented landscape in the Central Amazon characterized by primary forest fragments embedded i...
Modelling the empirical relationships between habitat quality and species distribution patterns is the first step to understanding human impacts on biodiversity. It is important to build on this understanding to develop a broader conceptual appreciation of the influence of surrounding landscape structure on local habitat quality, across multiple spatial scales. Traditional models which report t...
In this paper, a service economic analysis framework is developed and applied in order to define, understand, explain and improve landscape services. Together with the ecosystem functions and externalities approach, landscape services are understood as intentionally provided targeted outcomes of agricultural production, with the objective to improve landscape quality. Based on this conceptualis...
extended abstract 1. introduction city is a living creature formed through the interaction of different forces in unique substantiality. one of the main aspects of each city is its landscape; urban landscape is the experience of people as the members of society. landscape is an objective and subjective phenomenon that is the part of peoples’ nature in a city. in fact, the process of landscape p...
