Landscape ecological aspects of agro-ecosystems
Agriculture, Ecosystems & Environment, 1986Abstract This paper is concerned with landscape ecology and its relevance for both agriculture and the relation of agro-ecosystems to the total landscape. The term “landscape ecology” is not commonly used in agriculture, although subordinate concepts are often used, for example, the principle of soil and land suitability for agricultural development,

Natural Disasters and Coastal Agro-ecosystems
2019The coastal regions are prone to natural disasters, but the impact varies with the geographical location and adaptive capacity of the individual countries to cope with the post-disaster situations. Historical records show that cyclonic storm and flooding are the major disasters experienced, and these inflict heavy loss to agriculture and allied sectors.

The Origins of Plant Pathogens in Agro-Ecosystems
Annual Review of Phytopathology, 2008Plant pathogens can emerge in agricultural ecosystems through several mechanisms, including host-tracking, host jumps, hybridization and horizontal gene transfer. High-throughput DNA sequencing coupled with new analytical approaches make it possible to differentiate among these mechanisms and to infer the time and place where pathogens first emerged ...

Emergence of Research on Agro-Ecosystems
Annual Review of Ecology and Systematics, 1977Ecosystem research using a systems approach has been under way in ecology for about fifteen years, mostly as studies of energy flow and nutrient dynamics. During this time the methods of ecosystem analysis have been applied to a few lightly managed natural resource systems such as fisheries, forestry, and rangelands (30).

Assessing Productive Capacities of Agro-Ecosystems
2019The ability of an ecosystem to produce the raw materials and food necessary for human economic activities is termed ‘productive capacity’. The productive capacity of an ecosystem sets the physical limits for the provision of ecosystem services (ES), in turn defined as the benefits that humans gain from the natural environment.

Energy Status of Soil Agro-ecosystems
2013The activity and resilience of agro-ecosystems depend on soil – as a reservoir and biochemical reactor transforming substances and energy. But under cultivation, energy reserves have been much depleted. Protection of soil functions and solar gain in the form of soil organic matter is a priority for environmental protection.

Genotoxic Agents in the Agro-Ecosystem Chairman’s Comments
1982In our agro-ecosystem, there are at least four classes of genotoxic agents that have been detected and characterized: 1. Genotoxic metabolites produced by plants and fungi. 2. Genotoxic heavy metal salts found in the soil. 3. Genotoxic man-made chemicals used as pesticides and other agricultural chemicals.

Toxic Agents in the Agro-Ecosystem Chairman’s Comments
1982As we begin the session concerned with Toxic Agents In the Agro-Ecosystem, it seems proper to consider additional ways in which a chemical may interact with its target. While the first portion of this session dealt principally with the direct effects of mycotoxins acting on receptor systems, the following papers will offer possibilities wherein ...
