Exploiting Diversity to Manage Weeds in Agro-ecosystems

Weed management systems that rely less on chemical control are needed globally. Next to curative chemical weed control, there are other ways of tackling weed problems, such as (a) reduction of the weed seed bank in the soil, (b) reduced recruitment of weed seeds from the soil seed bank, and (c) strengthening the relative competitive ability of the crop. A number of case studies are presented in...

Diversity of Plants and Animals in Mountain Ecosystems in Tajikistan

Tajikistan is a hotspot of plant and animal species diversity and endemism andis important for the conservation of biodiversity on a global scale. The country is located ata biological crossroads. Species from Central and Northern Europe, Central Asia, theMiddle East, and North Africa mingle here with endemics found nowhere else. Therichness of Tajikistan‘s biodiversity shows up at the genetic,...

Simulation of Water and Carbon Fluxes in Agro- and forest Ecosystems at the Regional Scale

To investigate effects of different land use management practices on carbon fluxes at the regional scale we developed an integrated model by coupling an ecohydrological river basin model SWIM (Soil and Water Integrated Model) and a soil organic matter model SCN (Soil-Carbon-Nitrogen model). The latter is a submodel of the forest growth model 4C. The extended integrated model combines hydrologic...

Total Nitrogen Concentrations in Surface Water of Typical Agro- and Forest Ecosystems in China, 2004-2009

We assessed the total nitrogen (N) concentrations of 28 still surface water (lake and pond), and 42 flowing surface water (river), monitoring sites under 29 typical terrestrial ecosystems of the Chinese Ecosystem Research Network (CERN) using monitoring data collected between 2004 and 2009. The results showed that the median total N concentrations of still surface water were significantly highe...

Diet Diversity in Pastoral and Agro-pastoral Households in Ugandan Rangeland Ecosystems.

We explore how diet diversity differs with agricultural seasons and between households within pastoral and agro-pastoral livelihood systems, using variety of foods consumed as a less complex proxy indicator of food insecurity than benchmark indicators like anthropometry and serum nutrients. The study was in the central part of the rangelands in Uganda. Seventy nine households were monitored for...
