  • Progress in collaborative networks continues showing a growing number of manifestations including virtual organizations, virtual enterprises, dynamic supply chains, professional virtual communities, collaborative virtual laboratories, etc. with a wide spectrum of application domains. The realization that all these collaborative forms represent variations of a more general paradigm has lead to their consolidation into Collaborative Networks (CN) as anew scientific discipline.

  • Lenne, 1996) and to decrease damage by pests and pathogens (Cantelo & Sanford, 1984). In some crops (e.g. rice) this is applied on a large scale to maximize yield by minimizing damage by pathogens (Zhu et al., 2000). Information on genetic diversity and population structure also assists plant breeding in the selection of parents for crossing, providing a more rational basis for expanding the gene pool, and for identifying materials that harbor genes of value for plant improvement.

  • The World Bank’s mission is to alleviate poverty and support sustainable development. The conservation and sustainable use of natural habitats and biodiversity will contribute to these goals by protecting ecosystem services that are critical to fulfilling these objectives. Biodiversity is the foundation and mainstay of agriculture, forests, and fisheries. Biological resources provide the raw materials for livelihoods, sustenance, medicines, trade, tourism, and industry.

  • These pest infestations are infrequent and typically limited to breeding flocks or layers. Broilers and market turkeys are seldom if ever affected. Management of ectoparasites largely consists of whole flock treatments whenever infestations are detected by scouting birds and/or inspection of the structure and equipment (nest boxes, curtains, slats, cages). Other effective management techniques are not available. It is estimated that slightly more than 4 percent of breeder birds and layers are treated for ectoparasites each year.

  • Characterization of animal genetic resources for food and agriculture (AnGR) involves three types of information: phenotypic, genetic and historical. The weight given to each depends on the country (e.g. whether it is developed or developing) and the objective (e.g. improve- ment, conservation or breed differentiation). These guidelines focus on the collection and use of phenotypic information.

  • Genetic diversity is the fundamental source of biodiversity. In 1989, the World Wildlife Fund defined biodiversity as “the richness of life on Earth – millions of plants, animals and microorganisms, including the genes which they carry, and complex ecosystems that create the environment”. Currently, the issue of maintaining genetic diversity as a component of the conservation of biodiversity has been accepted at an international level. FAO has included the issue of conservation, evaluation, and the use of animal genetic resources in its fields of interest since the 1970s.

  • Agriculture has been theorized to have become the dominant way of producing food since the Neolithic Revolution. Through early biotechnology, the earliest farmers selected and bred the best suited crops, having the highest yields, to produce enough food to support a growing population. As crops and fields became increasingly large and difficult to maintain, it was discovered that specific organisms and their by-products could effectively fertilize, restore nitrogen, and control pests.

  • Broiler-breeder hens are first housed in open-floor environments or pens where they are reared to 20 to 22 weeks of age. The arrangement and management of these houses are similar to that described for broilers. Roosters are similarly housed until breeding age. The breeding flock (hens and roosters) is then transferred to production houses where hens begin to lay fertile eggs at about 24 weeks of age. The birds are held in production for an additional 36 to 44 weeks, at which time they are sold to the market.

  • Education is an important tool in the fight against HIV/AIDS. And while most schools are welcoming to children, some schools fail to provide the necessary protection for children to flourish and, in fact, may expose young people – especially girls – to violence. School cultures can contribute to gender violence. Often, gender stereotypes and inequities abound in the classroom, where different behaviours and roles are expected from girls and boys. Gender-based school violence takes many forms.
