Integrated forest management is faced with the challenge that the contribution of forests to economic and ecological planning targets must be assessed in a socio-ecological system context. This paper introduces a way to model spatio-temporal dynamics of biomass production at a regional scale in order to derive land use strategies that enhance biomass provision and avoid trade-offs for other eco...

Massachusetts is a rapidly growing state with evidence of development in many of its regions. South Hadley is an example of one such rapidly developing town in the state. Being a college community, with a low crime rate, and recently upgraded schools, South Hadley has become a desirable place to live. To the average town resident, South Hadley appears to be developing at an astronomical rate. O...

One of humanity's major challenges of the 21st century will be meeting future food demands on an increasingly resource constrained-planet. Global food production will have to rise by 70 percent between 2000 and 2050 to meet effective demand which poses major challenges to food production systems. Doing so without compromising environmental integrity is an even greater challenge. This study look...

Changes in land use and intensification of agricultural pressure have greatly accelerated the alteration of the landscape in most developed countries. These changes may greatly disturb the adjacent ecosystems, particularly streams, where the effects of pollution are amplified. In this study, we used the leaf litter breakdown rate to assess the functional integrity of stream ecosystems and river...

The application of XML-based approaches in passing vulnerability information between vulnerability management devices or software residing on wired networks has been demonstrated. We propose a proof of concept framework for mobile operators that extends this use of XML into the area of vulnerability management on public land mobile networks. Our proposed framework allows for a pro-active centra...

a special class of cubic graphs are the cycle permutation graphs. a cycle permutation graph pn(α) is defined by taking two vertex-disjoint cycles on n vertices and adding a matching between the vertices of the two cycles.in this paper we determine a good upper bound for tenacity of cycle permutation graphs.

oxidative stress has been identified as a crucial factor leading to male infertility largely due to peroxidativedamage to the sperm cell membrane. cadmium (cd) is a widespread environmental pollutant and oneof the well-known reproductive toxicants. because of its long biological half-life (10–30 years), cdaccumulates in the biological systems. the present study was designed to assess the concen...

Recent studies have implied the importance of incorporating configuration metrics into landscape-aquatic ecological integrity research; however few have addressed the needs of spatial data while exploring nonlinear relationships. This study investigates spatial dependence of a measure of aquatic ecological condition at two basin scales, and the spatial and non-linear role of landscape in explai...

Preservation of extraordinary natural resources, protection of water quality, and restoration of impaired waters require a strategy to identify and protect least-disturbed streams and rivers. We applied two objective, quantitative methods to determine stream ecological integrity of headwater reaches of 10 Ozark rivers, 5 with Wild and Scenic River federal protective status. Thirty-four variable...

SBAS and GBAS enhance standalone GNSS navigation to meet the safety and availability requirements of civil aviation. SBAS and GBAS are also freely available to other users, such as automobiles, buses, and trains on land as well as ships near shore. However, integrity as implemented there are significant differences between the aviation interpretation of navigation integrity and the one that wou...
