Globally, ecosystems and their constituent flora and fauna face the localized and broad-scale influence of human activities. Conservation practitioners and environmental managers struggle to identify and mitigate threats, reverse species declines, restore degraded ecosystems, and manage natural resources sustainably. Scientific research and evidence are increasingly regarded as the foundation f...
Increasing atmospheric CO2 concentration has led to concerns about potential effects on production agriculture as well as agriculture’s role in sequestering C. In the fall of 1997, a study was initiated to compare the response of two crop management systems (conventional and conservation) to elevated CO2. The study used a split-plot design replicated three times with two management systems as m...
In this paper, we propose a management price framework to inform decision making directed at the land-management unit level when biodiversity is one of several land-management objectives. The management prices synthesize information about the production relationships that link the public goods aspects of biodiversity to land-management activities. High management prices indicate high marginal r...
Although it is widely acknowledged that rising atmospheric CO2 concentrations will increase crop root growth, no study has considered how this response could be influenced by agricultural management practices. Therefore, we examined the influence of elevated atmospheric CO2 (ambient + 360 mmol mol ) on root dynamics of sorghum (Sorghum bicolor) produced under conventional (tillage following win...
Globally, the number of recreational fishers is sizeable and increasing in many countries. Associated with this trend is the potential for negative impacts on fish stocks through exploitation or management measures such as stocking and introduction of non-native fishes. Nevertheless, recreational fishers can be instrumental in successful fisheries conservation through active involvement in, or ...
The goal of the PRIN2005 “EAH conservation KM system” research project, funded by Italian Ministry of Research, is to establish an advanced integrated approach to conservation of Earthen Architecture Heritage (EAH) that support main design and planning of conservation actions, reducing the technical risk through suitable and compatible measures. Knowledge Management for supporting EAH conservat...
