The protection of low porosity stones, as marbles, from atmospheric deterioration is challenging and scarcely documented in literature in terms of evaluation of the performances of conservation treatments exposed to real conditions.
Consequently, I suggest that more attention should be given to two topics, first, how the performance of a conservation plan should be evaluated, and second, what are the consequences of simplifying the ideal conservation resource allocation model?
The spatial variations of root biomass make the performance of soil conservation and reinforcement of the soil-root system change along with altitude gradient.
This period of time between repetitions may be set in absolute terms (a specified number of years, once again chosen by convention) or determined by keeping track of explicitly specified indicators of the performance of a conservation area network.
At the fourth stage, the performance of existing conservation areas (if any) in satisfying the targets and other biological design criteria (established during the third stage) must be assessed.
Compare to traditional wake-up circuits which directly judge the energy of received signals, our approach can greatly reduce the misjudgment caused by the environmental disturbance, and the performance of energy conservation is effective.
We highlight the practical implications of this kind of research, and the importance of quantitative data in evaluating the overall performance of conservation policy.
The objectives and performance of conservation initiatives, in the Coral Triangle and elsewhere, are measured mainly in terms of inputs (e.g. dollars invested), outputs (e.g. protected area extent), or, less commonly, outcomes (e.g. representation of marine ecosystems in protected areas).
We compare the performance of a conventional integrated conservation and development policy (ICDP) with an alternative hybrid policy that combines features of ICDP and payments for environmental services.
