Rangelands are globally extensive, provide fundamental ecosystem services, and are tightly coupled human-ecological systems. Rangeland sustainability depends largely on the implementation and utilization of various grazing and burning practices optimized to protect against soil erosion and transport. In many cases, however, land management practices lead to increased soil erosion and sediment f...

Renewable groundwater stress is quantified in the world's largest aquifersCharacteristic stress regimes are defined to determine the severity of stressOverstressed aquifers are mainly in rangeland biomes with some croplands.

al., 1994). Summed to 1-m depth, SOC content was not different between cropland and conservation reserve. Estimates of potential soil organic C (SOC) and total N (TN) In a shortgrass-steppe with 56 yr of grazing in Colorado, sequestration at depths below the traditional plow layer (i.e., 0–0.3 m) in agricultural systems are needed to improve our understanding of SOC was not different between un...

The need to balance biodiversity conservation with sustainable development, though widely agreed upon, is elusive in practice. Human societies are increasingly disconnected from the ecosystems which support them. The loosening connection and growing scientific acceptance that ecosystems are complex, dynamic, non-linear systems pose new challenges for rangeland monitoring. Consequently, although...

Restoration and revegetattion of rangeland ecosystems is based on knowledge of abiotic and biotic interactions that affect plant establishment. Once plants become autotropbic, interactions within and between plant species may occur and these interactions may range from antagonistic to mutualistic. This full range of potential interactions needs to be considered to ensure successful revegetation...

Agricultural practices, including habitat alteration and application of agricultural chemicals, can impact wildlife resulting in their decline. Determining which of these practices are contributing to declines is essential if the declines are to be reversed. In this study, the health of two geographically separated sleepy lizard (Tiliqua rugosa) populations was compared between a rangeland envi...

Comparing Actual and Potential Productions of Rangeland Ecosystems Kohgiluyeh Boyer-Ahmad Province in Different Conditions

Social Media has infiltrated all manner of users, and none more than the current digital native who is studying at university. This has led to the rise in questions of how best to use these computermediated communications in academic settings. Recent research shows that Twitter is very popular amongst students, though little work exists on the impact of Tweeting, and how it can be measured. Thi...

Analysis of Barriers and Challenges Rangeland Management (Case Study: Rangelands Kermanshah province)

rangeland health assessment provides qualitative information on ecosystemattributes. we examined changes in rangeland health in the zagros semi-arid rangelands ofiran at fixed sites between 2001 and 2011, over the 10-year period. the rangelandfragments significantly declines in the quality of the vegetation, and changes in plantspecies were driven largely by seasonality, and to a lesser extent,...
