A mixed-model moving-average approach to geostatistical modeling in stream networks. Ecology 91:644–651. South East Queensland (SEQ) is located on the eastern coast of Australia and is approximately 22,999 square km in size. It is a subtropical region with mean annual maximum temperatures ranging between 21 and 29 °C (EHMP, 2001) and total annual rainfall ranges between 900 and 1800 mm (Pusey e...

This study aims to improve the health of rural Amazonian communities through the development and application of a participatory ecosystem approach to human health assessment. In the study area marked seasonal fluctuations dictate food availability, water quality and disease outbreak. Determining the causal linkages between ecosystem variables, resource use and health required a variety of forms...

The health of a software ecosystem is argued to be a key indicator of well-being, longevity and performance of a network of companies. In this paper, we addresswhat scientific literature actuallymeanswith the concept of ‘ecosystem health’ by selecting relevant articles with systematic literature review. Based on the final set of 38 papers, we found that despite a common base, the term has been ...

The Loess Plateau is well known for its deep loess deposits and serious soil erosion. This paper analyses the characteristic of soil erosion on the Plateau and reviews the small watershed management and ecosystem rehabilitation practice and development in the future. In the last 30 years, the government has paid great attention on the integrated small watershed management and restoration of the...

Globalization can have substantial impact on local commons by reducing sustainability of ecosystems and their vital services. Without effective local institutions, these resources are at high risk of exploitation, especially to feed global markets. This study proposes a multiscale ecosystem framework (MEF) that incorporates information on ecosystem components, socioeconomic processes, and their...

Phytoplankton are crucial to marine ecosystem functioning and are important indicators of environmental change. Phytoplankton data also are also essential for informing management and policy, particularly in supporting the new generation of marine legislative drivers, which take a holistic ecosystem approach to management. The Marine Strategy Framework Directive (MSFD) seeks to achieve Good Env...

Phenological shifts in events such as flowering and bud break are important indicators of ecosystem processes, and are therefore of particular significance for carbon (C) cycle research. Using long-term flux data from three contrasting plant functional type (evergreen and deciduous) boreal forest sites, we evaluated and compared the responses of annual C fluxes to multiple spring phenological i...

The National Park of Las Tablas de Daimiel in Central Spain is a wetland area of great value regarding biodiversity and wildlife habitat. This type of ecosystem is unique within a semi-arid climate and especially sensitive to degradation processes caused by growing pressure on natural resources (agricultural practices, groundwater depletion and land use change) as well as climatic changes. The ...

1. Traditionally the assessment of river water quality has been based solely on the measurement of physical, chemical and some biological characteristics. While these measurements may be efficient for regulating effluent discharges and protecting humans, they are not very useful for large-scale management of catchments or for assessing whether river ecosystems are being protected. 2. Measuremen...
