Assessing wildlife habitat suitability for ecological sites and state and transition models
… habitat is an important component of rangeland management plans. Unfortunately, there are few practical tools to assist managers in understanding how management and environmental variation affects habitat suitability. Ecological site descriptions (ESDs) have the potential to fill this role …

Linking ecosystem services with state-and-transition models to evaluate rangeland management decisions
Rangelands are a major type of land found on all continents. Though they comprise around 70% of the world's land area, knowledge of rangelands is limited and immature. Rangelands supply humans with food and fiber at very low energy costs compared to cultivated lands. They are inherently …

Effects of pretreatment tree dominance and conifer removal treatments on plant succession in sagebrush communities
… tridentata Nutt.) communities, the expansion and infilling of conifers decreases perennial vegetation cover and density, and lowers ecosystem resilience and resistance of the shrub-grass dominated state. Successional trajectories following disturbance are highly dependent upon residual species …

Dynamic Invariant Generation for Concurrent Programs
We propose a fully automated and dynamic method for generating likely invariants from multithreaded programs and then leveraging these invariants to infer atomic regions and diagnose concurrency errors in the software code. Although existing methods for dynamic invariant generation perform …

Computational Approaches for Understanding and Redesigning Enzyme Catalysis
The remarkable specificity and catalytic efficiency of many enzymes make them attractive for applications ranging from therapeutics to chemical manufacturing. However, it remains challenging to identify the specific structural and dynamic mechanisms underlying the catalytic power of enzymes, which …

Rangeland condition in the Ceres Karoo: the importance of long-term studies
… Karoo vegetation has long been acknowledged, and there is a need for researchers and managers to better understand the dynamics and processes leading to vegetation degradation and recovery. Despite the fact that these arid systems tend to hold high demographic inertia, as well as being prone …

Trapped? Evidence of changes in relative plant abundance after long-term grazing exclosure across the Tundra.
… link between the relative palatability of plants and ecosystem functions. By changing the relative abundance of certain plant species, prolonged or intense grazing can affect ecosystem processes and lead to land degradation. Management interventions such as grazing exclusion can help an ecosystem …

Optical and core-level X-ray spectroscopy of correlated two-dimensional materials
The intersection of low-dimensionality and strongly correlated electrons in van der Waals (vdW) materials offers a rich landscape of ordered phases and associated excitations for potential applications in nanoelectronics. The coupling between distinct degrees of freedom in correlated materials …

The value of animal behaviour as a bio-indicator of restoration quality
Woodland restoration is a complex endeavour, and restoration ecology as a scientific discipline requires constant re-assessments and adjustments if it is to improve outcomes and better provide for biodiversity. The promise of effective restoration is often used to justify destructive processes that …

Ecosystem impacts of tamarisk (Tamarix spp.) management in the Arkansas River watershed, Colorado: effects of disturbance and herbicide residues on passive plant community restoration
… species of woody plants along waterways in arid and semi-arid areas of the western United States. Tamarisk was intentionally introduced over a century ago for ornamental purposes and erosion control projects, but its expansion since has been influenced by altered hydrologic regimes and global …
