A classification of spatial simulation models of fire and vegetation dynamics (landscape fire succession models or LFSMs) is presented. The classification was developed to provide a foundation for comparing models and to help identify the appropriate fire and vegetation processes and their simulation to include in coarse scale dynamic global vegetation(More)
Evidence is accumulating that the continued provision of essential ecosystem services is vulnerable to land-use change. Yet, we lack a strong scientific basis for this vulnerability as the processes that drive ecosystem-service delivery often remain unclear. In this paper, we use plant traits to assess ecosystem-service sensitivity to land-use change in(More)
The purpose of this study was to compare the sensitivity of modelled area burned to environmental factors across a range of independently-developed landscape-fire-succession models. The sensitivity of area burned to variation in four factors, namely terrain (flat, undulating and mountainous), fuel pattern (finely and coarsely clumped), climate (observed,(More)
Environmental disturbance underpins the dynamics and diversity of many of the ecosystems of the world, yet its influence on the patterns and distribution of genetic diversity is poorly appreciated. We argue here that disturbance history may be the major driver that shapes patterns of genetic diversity in many natural populations. We outline how disturbance(More)
Wildland fire intensity influences natural communities, soil properties, erosion, and sequestered carbon. Measuring effectiveness of fuel treatment for reducing area of higher intensity unplanned fire is argued to be more meaningful than determining effect on total unplanned area burned. To contrast the relative importance of fuel treatment effort, ignition(More)
Wildland fire is a major disturbance in most ecosystems worldwide (Crutzen and Goldammer 1993). The interaction of fire with climate and vegetation over long time spans, often referred to as the fire regime These effects include cycling nutrients, regulating succession, maintaining diversity, reducing biomass, controlling insect and disease populations,(More)
Changing land use is one of the major threats to biodiversity in all regions of the world, especially in regions where, over the last few decades, societal changes (globalization) have resulted in rapid changes in agricultural systems. In Europe, mountain regions are recognized as particularly vulnerable in terms of land-use change implications for(More)
A bioanalytical method for the determination of the anticancer drug chlorambucil (Leukeran) and its phenyl acetic acid mustard metabolite in human serum and plasma is described. Automated solid-phase extraction of the analytes is carried out with C18 sorbent packed in a 96 well format microtitre plate using a robotic sample processor. The extracts are(More)
Exploring interactions between ecological disturbance, species' abundances and community composition provides critical insights for ecological dynamics. While disturbance is also potentially an important driver of landscape genetic patterns, the mechanisms by which these patterns may arise by selective and neutral processes are not well-understood. We used(More)
