Sustainability and integrated weed management in Australian winter cropping systems: a bioeconomic analysis
Economic evaluations of the benefits of integrated weed management often only consider the benefits of management in the crop phase, and ignore the impact of rotational options. In particular, non-crop phases such as annual and perennial pasture phases can have a substantial impact upon weed population dynamics and economic returns. Moreover, extended perennial pasture phases are being promoted...
متن کاملImpacts of IOD, ENSO and ENSO Modoki on the Australian Winter Wheat Yields in Recent Decades
Impacts of the Indian Ocean Dipole (IOD), two different types of El Niño/Southern Oscillation (ENSO): canonical ENSO and ENSO Modoki, on the year-to-year winter wheat yield variations in Australia have been investigated. It is found that IOD plays a dominant role in the recent three decades; the wheat yield is reduced (increased) by -28.4% (12.8%) in the positive (negative) IOD years. Although ...
متن کاملWinter 2001
Based on research conducted by NCBI’s comparative genomics group, the database of Clusters of Orthologous Groups of proteins (COGs) represents a phylogenetic classification of proteins encoded in complete genomes. The COGs are derived from an “all-against-all” sequence comparison of the encoded proteins. Each COG consists of individual proteins or groups of paralogs from at least three lineages...
متن کاملWinter worries
spend the next nine months without making landfall. And it is becoming increasingly clear that very little is known about the birds during this time. As they breed only above 50 degrees latitude, they are considered cold-water birds, but researchers working with puffins breeding at England's largest colony on the Farne Islands are concerned about their winter environment as there has recently b...
متن کاملControl of delta arrowhead (Sagittaria platyphylla) in Australian irrigation channels with long exposure to endothall dipotassium salt during winter
Delta arrowhead [Sagittaria platyphylla (Engelm.) J.G. Sm.] is an emergent, aquatic plant, originating from North America, which has invaded aquatic environments in Australia. The plant is particularly problematic in southeast Australia, where it invades earthen irrigation channels and drains. Hydraulic capacity is subsequently reduced, leading to a reduction in the efficiency of water delivery...
