effects of fencing on carbon stocks in the degraded alpine grasslands of the Qinghai-Tibetan Plateau

Journal Articles & Books
December, 2013

Quantifying the carbon storage of grasslands under different management strategies can help us understand how this ecosystem responds to different land management practices. To assess the C cycle and the importance of soil microbial biomass carbon, we measured the levels of soil organic carbon, biomass carbon (above- and underground) and soil microbial biomass carbon in areas with different grazing intensities and different management strategy (fenced and unfenced) in the Qinghai-Tibetan Plateau.

Daytime Habitat Selection by Resident Golden Eagles (Aquila chrysaetos) in Southern Idaho, U.S.A

Journal Articles & Books
December, 2015

Energy and other anthropogenic development are increasing throughout the range of Golden Eagles (Aquila chrysaetos) in western North America, and both private and government agencies have expressed concern about indirect and direct effects on Golden Eagles. To facilitate sustainable development and reduce risk to Golden Eagles, the U.S. Fish and Wildlife Service has established guidelines to assist developers in project planning and siting. A major component of environmental impact assessment is documenting Golden Eagle spatial use near a project site before development.

Identifying Diverse Conservation Values for Place-Based Spatial Planning Using Crowdsourced Voluntary Geographic Information

Journal Articles & Books
December, 2016

The values of conservationists and planners will affect their decisions, tools, and practice, while the values of the public will affect the social acceptability of different management actions and, consequently, the likely success of implementation. This study investigates how voluntary geographic information systems (VGI) can be used to identify areas important for anthropocentric and biocentric values across a spatial planning region to inform place-based conservation planning.

Response of soil microbial and invertebrate communities to tracked vehicle disturbance in tallgrass prairie

Journal Articles & Books
December, 2009

Soil biota drive fundamental ecosystem processes such as decomposition, nutrient cycling, and maintenance of soil structure. They are especially active in grassland ecosystems such as the tallgrass prairie, where much of the net primary productivity is allocated belowground and ultimately processed by heterotrophic soil organisms.

Soil organic matter of Iberian open woodland rangelands as influenced by vegetation cover and land management

Journal Articles & Books
December, 2013

Spanish rangelands occupy more than 90,000km² of land grazed by millions of domestic and wild animals. Organic matter content of soil is an essential component for fertility and productivity in both, natural and human-induced ecosystems. Despite its importance to soil quality, soil organic carbon has been little studied in these rangelands. The main goal of this study is to assess the amounts and characteristics of soil organic matter in grazed open woodlands of SW Iberia as influenced by vegetation cover and land management.

Extending the timescale and range of ecosystem services through paleoenvironmental analyses, exemplified in the lower Yangtze basin

China

In China, and elsewhere, long-term economic development and poverty alleviation need to be balanced against the likelihood of ecological failure. Here, we show how paleoenvironmental records can provide important multidecadal perspectives on ecosystem services (ES). More than 50 different paleoenvironmental proxy records can be mapped to a wide range of ES categories and subcategories. Lake sediments are particularly suitable for reconstructing records of regulating services, such as soil stability, sediment regulation, and water purification, which are often less well monitored.

review of a community-based approach to combating land degradation: dryland salinity management in Australia

Journal Articles & Books
December, 2008
Australia

Degradation of farmland caused by salinisation is a major environmental issue in Australia. To combat salinisation a community-based approach has been adopted. This paper reviews the nature and effectiveness of this approach, describing its rationale, strengths and weaknesses. The community-based approach is shown to have been highly successful in raising awareness and providing education about the problem of dryland salinity in Australia, and has encouraged group participation in managing the problem.

Seagrass rehabilitation off metropolitan Adelaide: a case study of loss, action, failure and success

Journal Articles & Books
December, 2014

Heavy losses of 6200 ha of seagrass off the Adelaide metropolitan coast since 1949 have had substantial implications for beach management, fisheries and biodiversity. Here, we describe for managers some promising initial trials to develop a cost‐effective method to rehabilitate some of these lost seagrasses.
