One Century of Treeline Change and Stability – Experiences from the Swedish Scandes

This paper elaborates and visualizes processes recorded in a recent regional and multi-site study of elevational treeline dynamics during the period 1915 to 2007 in the Swedish Scandes. The purpose is to give a concrete face of the landscape transformation which is associated with the recorded treeline shifts. The main focus is on stand-level structure of past and present treelines …

Do flying beetles respond to human-dominated landscapes as complex mosaics or binary patterns?

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 …

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

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 …

Transdisciplinary Challenges for Sustainable Management of Mediterranean Landscapes in the Global Information Society

The present chaotic transformation from the industrial to the global information society is accelerating the ecological, social and economic unsustainability. The rapidly growing unsustainable, fossil energy powered urban-industrial technosphere and their detrimental impacts on nature and human well-being are threatening the solar energy powered natural and seminatural biosphere landscapes and their vital ecosystem services. A sustainability revolution is therefore urgently …

Evaluating Anthropogenic Risk of Grassland and Forest Habitat Degradation using Land-Cover Data

The effects of landscape context on habitat quality are receiving increased attention in conservation biology. The objective of this research is to demonstrate a landscape-level approach to mapping and evaluating the anthropogenic risks of grassland and forest habitat degradation by examining habitat context as defined by intensive anthropogenic land uses at multiple spatial scales. A landscape mosaic model classifies a …

Reasons for an outstanding plant diversity in the tropical Andes of Southern Ecuador

Long-term field studies in the scope of a multidisciplinary project in southern Ecuador revealed extraordinary high species numbers of many organismic groups. This article discusses reasons for the outstanding vascular plant diversity using a hierarchical scale-oriented top-down approach (Grüninger 2005), from the global scale to the local microscale. The global scale explains general (paleo-) ecological factors valid for most parts …

Plant species richness and composition in the arable land of Kosovo

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, …

Contribution of landscape metrics to the assessment of scenic quality – the example of the landscape structure plan Havelland/Germany

The scenic quality of a landscape is a natural resource that is to be preserved according to German and international law. One important indicator for the evaluation of this value is the structural diversity of the landscape. Although Landscape Metrics (LM) represent a well-known instrument for the quantification of landscape patterns, they are hardly used in applied landscape and environmental …

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

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). The exploration of the research object is based on the starting …

Agricultural Set-aside Programs and Grassland Birds: Insights from Broad-scale Population Trends

The Conservation Reserve Program (CRP) is a voluntary set-aside program in the United States designed to ameliorate soil erosion, control crop overproduction, enhance water quality, and provide wildlife habitat by replacing crops with other forms of land cover. Because CRP includes primarily grass habitats, it has great potential to benefit declining North American grassland bird populations. We looked at the …
