Biorefineries: Relocating Biomass Refineries to the Rural Area

Peer-reviewed publication
Julho, 2012

The field for application of biomass is rising. The demand for food and feeding stuff rises while at the same time energy, chemicals and other materials also need to be produced from biomass because of decreasing fossil resources. However, the biorefinery ideas and concepts can help to use the limited renewable raw materials more efficiently than today. With biorefineries, valuable products, such as platform chemicals, can be produced from agricultural feedstock, which can subsequently be further processed into a variety of substances by the chemical industry.

Perception and Value of Nature in Urban Landscapes: a Comparative Analysis of Cities in Germany, Chile and Spain

Peer-reviewed publication
Setembro, 2008
Chile
Alemanha
Espanha

Cities are not socially homogenous, but divided into socially and structurally differentiated sub-units. Likewise, the individuals of a community, city or neighbourhood present specific behavioural patterns and uses with respect to their public green areas. This premise has led us to explore the question of how the perceptions, uses, and behaviours of people from different countries, cultures, and socioeconomic levels in Chile, Germany and Spain differ or coincide as far as urban nature and landscapes are concerned.

Landscapes‘ Capacities to Provide Ecosystem Services – a Concept for Land-Cover Based Assessments

Peer-reviewed publication
Dezembro, 2009
Alemanha

Landscapes differ in their capacities to provide ecosystem goods and services, which are the benefits humans obtain
from nature. Structures and functions of ecosystems needed to sustain the provision of ecosystem services are altered
by various human activities. In this paper, a concept for the assessment of multiple ecosystem services is proposed
as a basis for discussion and further development of a respective evaluation instrument. Using quantitative and

Demographic changes and the demands on agricultural landscapes: Refl ections on a new research topic

Peer-reviewed publication
Dezembro, 2008

Demographic change suggests substantial effects on future societal demands on agricultural landscape use and thus on rural areas. Demographic change is thereby defined as both the decrease of the population and the shift in the age distribution („aging“) and in the spatial distribution („rural flight“ particularly of young people).

Sustainable landscape development and value rigidity: the Pirsig‘s monkey trap

Peer-reviewed publication
Março, 2015

New broader, adaptable and accommodating sets of themes have been proposed to help to identify, understand and solve sustainability problems. However, how this knowledge will foster decisions that lead to more desirable outcomes and analyses necessary to transition to sustainability remains a critical theoretical and empirical question for basic and applied research. We argue that we are still underestimating the tendency to lock into certain patterns that come at the cost of the ability to adjust to new situations.

Do Flying Beetles Respond to Human-Dominated Landscapes as Complex Mosaics or Binary Patterns?

Peer-reviewed publication
Fevereiro, 2010

Understanding and measuring functional connectivity for animals with habitats that have been fragmented by human
activity requires that the biology and movement of the species be considered. We used least cost paths in GIS
to test hypotheses regarding how different species of longhorned beetles likely connect habitats with dispersal.
We predicted that there would be differences in the functional connectivity of landscapes depending on species
larval niche breadth, adult feeding habits, and the potential for use of non-forest habitats. For the species with very

Effects of topography and surface roughness in analyses of landscape structure –

Peer-reviewed publication
Fevereiro, 2008

Topography and relief variability play a key role in ecosystem functioning and structuring. However, the most commonly used concept to relate pattern to process in landscape ecology, the so-called patch-corridor-matrix model, perceives the landscape as a planimetric surface. As a consequence, landscape metrics, used as numerical descriptors of the spatial arrangement of landscape mosaics, generally do not allow for the examination of terrain characteristics and may even produce erroneous results, especially in mountainous areas.

Geometric approaches to computing 3D-landscape metrics

Peer-reviewed publication
Dezembro, 2010

The relationships between patterns and processes lie at the core of modern landscape ecology. These dependences
can be quantified by using indices related to the patch-corridor-matrix model. This model conceptualizes
landscapes as planar mosaics consisting of discrete patches. On the other hand, relief variability is a key factor for
many ecological processes, and therefore these processes can be better modeled by integrating information concerning
the third dimension of landscapes. This can be done by generating a triangle mesh which approximates

The Environmental Effects of Global Changes on Northeast Central Europe in the Case of Non-Modified Agricultural Management

Peer-reviewed publication
Junho, 2008

Climate impact scenarios for agriculture usually consider yield development, landscape water balance, nutrient dynamics or the endangerment of habitats separately. Scenario results are further limited by roughly discriminated land use types at low spatial resolution or they are restricted to single sites and isolated crops. Here, we exemplify a well data based comprehensive sensitivity analysis of a drought endangered agrarian region in Northeast Germany using a 2050 climate scenario.

Plant species richness and composition in the arable land of Kosovo

Peer-reviewed publication
Março, 2009

This study investigates today’s plant species richness and composition in cultivated and recently abandoned
arable land of Kosovo. Relationships between these aspects of vegetation and both environmental features
and agricultural management measures are studied at the regional and plot scale. In 2006, 432 vegetation relevés
with a standard plot size of 25 m² were recorded in cultivated fields. In 2007, data collection focussed on 41 plots
in arable fields that had been abandoned the year before. With respect to the environment, data analysis accounts

Peninsula Effects on Birds in a Coastal Landscape: Are Coves More Species Rich than Lobes?

Peer-reviewed publication
Outubro, 2012
Estados Unidos

Peninsula effects - decreasing richness with increasing distance along peninsula lobes - have been identified for
many taxa on large peninsulas. Peninsula effects are caused by differences in colonization and extinction predicted
by island biogeography or by environmental gradients along the peninsula. We compared species-area regressions
for cove patches (i.e., mainland) to regressions for lobe patches (i.e., on peninsula tips) for wet meadow birds
along a highly interdigitated shoreline (northern Lake Huron, USA). We conducted analysis both with and without

Treeline advance - driving processes and adverse factors

Peer-reviewed publication
Junho, 2007

The general trend of climatically-driven treeline advance is modified by regional, local and temporal variations. Treelines will not advance in a closed front parallel to the shift of any isotherm to higher elevations and more northern latitudes. The effects of varying topography on site conditions and the after-effects of historical disturbances by natural and anthropogenic factors may override the effects of slightly higher average temperatures. Moreover, the varying treeline-forming species respond in different ways to a changing climate.
