Determining pattern–process relationships in heterogeneous landscapes
Landscapes are now being altered at unprecedented rates (Forman and Alexander 1998), resulting in the loss and fragmentation of critical habitats (Gardner et al. 1993), declines in species diversity (Quinn and Harrison 1988, Gu et al. 2002), shifts in disturbance regimes (He et al. 2002, Timoney 2003), and threats to the sustainability of many ecosystems (Grime 1998, Simberloff 1999). Because t...
متن کاملDesigning Antibiotic Cycling Strategies by Determining and Understanding Local Adaptive Landscapes
The evolution of antibiotic resistance among bacteria threatens our continued ability to treat infectious diseases. The need for sustainable strategies to cure bacterial infections has never been greater. So far, all attempts to restore susceptibility after resistance has arisen have been unsuccessful, including restrictions on prescribing [1] and antibiotic cycling [2], [3]. Part of the proble...
متن کاملDetermining Causes of Pacific Madrone Decline in Urban Landscapes of the Pacific Northwest
In order to determine factors contributing to the decline of the Pacific madrone (Arbutus menziesii), 103 trees were surveyed and rated on a scale of 1–4. The performance rating was then compared with the following plant parameters and site conditions: size, growth habit, bark characteristics, location and size of cankers on the trunk, light exposure, slope, soil characteristics, management pra...

متن کاملConvergence and Sampling in Determining Free Energy Landscapes for Membrane Protein Association
Potential of mean force (PMF) calculations are used to characterize the free energy landscape of protein-lipid and protein-protein association within membranes. Coarse-grained simulations allow binding free energies to be determined with reasonable statistical error. This accuracy relies on defining a good collective variable to describe the binding and unbinding transitions, and upon criteria ...
