Biotechnology has had an important impact on the agricultural and food industries over the last twelve years by way of fast and extensive adoption of a few genetically modified (GM) crops. This has produced large efficiency gains, including higher yields and reduced costs of weed and pest control, as well as some environmental benefits. The expected development of crops with additional agronomi...

Insulin-like growth factor binding protein 2 regulates a broad spectrum of biological activities involved in growth, development, and differentiation. The current study was designed to investigate the associations of IGFBP2 gene polymorphisms with chicken growth and body composition traits. The Northeast Agricultural University Resource Population (NEAURP) was established by crossing broiler si...

Divergent natural selection is considered an important force in plant evolution leading to phenotypic differentiation between populations exploiting different environments. Extending an earlier greenhouse study of population differentiation in the selfing annual plant Senecio vulgaris, we estimated the degree of population divergence in several quantitative traits related to growth and life his...

Production traits such as growth, feed efficiency, survival, and fillet yield are economically important traits and an improvement in one or more of these traits will benefit the U.S. catfish farming industry. The U.S. Department of Agriculture (USDA) 103 line of channel catfish was developed jointly between the USDA Agricultural Research Service (ARS) Catfish Genetics Research Unit, Stoneville...

with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...

Faced to the present agro-environmental information features, there exist several difficulties to acquire and control the agricultural environment information, such as the scattered information with spatio-tempel traits, the methods of quantification and the huge data amount. This paper constructed an agroenvironmental information service system based on the spatial database, computer network a...

Invasive alien species can have serious adverse impacts on both the environment and the economy. Being able to predict the impacts of an alien species could assist in preventing or reducing these impacts. This study aimed to establish whether there are any life history traits consistently correlated with the impacts of alien birds across two continents, Europe and Australia, as a first step tow...
