Grazing exclosures solely are not the best methods for sustaining alpine grasslands

Is grazing exclusion effective in restoring vegetation in degraded alpine grasslands in Tibet, China?

Overgrazing is considered one of the key disturbance factors that results in alpine grassland degradation in Tibet. Grazing exclusion by fencing has been widely used as an approach to restore degraded grasslands in Tibet since 2004. Is the grazing exclusion management strategy effective for the vegetation restoration of degraded alpine grasslands? Three alpine grassland types were selected in T...

Effects of Grazing on Above- vs. Below-Ground Biomass Allocation of Alpine Grasslands on the Northern Tibetan Plateau

Biomass allocation is an essential concept for understanding above- vs. below-ground functions and for predicting the dynamics of community structure and ecosystem service under ongoing climate change. There is rare available knowledge of grazing effects on biomass allocation in multiple zonal alpine grassland types along climatic gradients across the Northern Tibetan Plateau. We collected the ...

Withdrawing and withholding life-sustaining therapies are not the same

Numerous lines of evidence support the premise that withholding and withdrawing life support measures in the intensive care unit are not the same. These include questionnaires, practical observations and an examination of national medical guidelines. It is important to distinguish between the two end of life options as their outcomes and management are significantly different. Appreciation of t...

Straight ROBDDs are not the Best for Pos

The subject of groundness analysis for (constraint) logic programs has been widely studied, and interesting domains have been proposed. Pos has been recognized has the most suitable domain for capturing the kind of dependencies arising in groundness analysis. Its (by now standard) implementation is directly based on reduced ordered binary-decision diagrams (ROBDDs), a well-known symbolic repres...
