Scien.net Publishes Chromosome and Crossbred Bibliography, and a Mobile Site

Share Article

The novel Natural Sciences Bibliographic Web Portal aims to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences. The site has now included the two new sections Chromosome and Crossbred. While the publishers target to publish a total of over 21 million references until 2014, the site currently contains over 960,000 posts, increasing by about 10,000 items every day. All content is now available for mobile viewing. References contain a minimum of bibliographic information including title, authors, publication year and source and almost 50% of them additionally contain a summary of the publication's scientific content. All references are tagged with scientific keywords which cross-connect them.

Chromosome & Crossbred Bibliography @ Scien.net

The aim of the Natural Sciences Bibliographic Web Portal including its two new Chromosome and Crossbred References sections is to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences. The information contains a minimum of bibliographic information consisting of title, authors, publication year and source while expanded references provide an additional summary of the publication's scientific content. All references are grouped into eleven main sections which are subdivided into ten categories each. The site as well as every section and category provides RSS feeds alerting the site's users of newly published content. Every bibliographic reference is tagged with up to twenty scientific keywords which cross-connects them beyond sections and categories.

The section Breeding contains information on the evaluation of the genetic value of domesticated animals or plants using best linear unbiased prediction and other methods. Animal breeding is the selection of animals with superior estimated breeding value in growth rate, egg, meat, milk, or wool production. Plant breeding is the art and science of changing the genetics of plants in order to produce desired characteristics. It can be accomplished through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to more complex molecular techniques. The latest content in this category is also available through a Breeding RSS feed. The section currently contains circa 33,620 posts and is subdivided into ten categories including Chromosome, Crossbred, Genetic, Genotype, Germplasm, Hybrid, Lactation, Offspring, Phenotype and Resistance.

Within this section, the category Chromosome contains information on this organized building of DNA and protein that is found in cells. A chromosome is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. The category currently contains circa 360 posts of which the latest inclusions are also available through a Chromosome RSS feed. It features a post on Genetic analysis of the T-H-2 region in non-T chromosomes and the proof that two new congenic strains isolate Qglo-1 from H-2. It also covers the theory and practice of egg transformation and parthenogenetic diploidy induced through the aid of ionizing radiation. Other posts covers the distribution of the 1/29 and 14/20 Robertsonian translocation in Romanian Simmental (Romanian Spotted) sires, and the cytogenetics and breeding behaviour of X-ray induced chlorophyll mutants in Vigna mungo (Linn) Hepper. Other posts cover the cytology and breeding behavior of cicer milkvetch and the cytogenetics of distant hybrids and problems of breeding.

The new category Crossbred covers animals or plants produced by mating or hybridizing two different species, breeds, or varieties. Crossbreeding refers to the reproduction between two distinct conspecific gene pools and can also be defined as a mating system in which two or more breeds are combined, usually in a systematic fashion to make use of heterosis and breed complementarity. The category currently contains circa 1,330 posts of which the latest inclusions are also available through a Crossbred RSS feed. It features a reference presenting new aspects of genetic improvement of prolificacy in pigs, a post on measuring breeding efficiency by pregnancy diagnosis and by non-returns in Hariana and cross-bred cattle, and one covering mathematical modeling of crossbreeding in beef cattle including the evaluation of cow replacement decisions when mating plan and breed size are varied.

Scien.net now also features a newly published Natural Sciences Bibliography Mobile Site optimized for mobile viewing. This mobile site provides all content of the site but optimized for display on mobile devices.

While the publishers of the web portal have a stock of 21,238,124 references of which 10,564,269 (50%) contain a summary, this information will be made successively available to the public until 2014. While the site has presently published a total of 960,000 posts online, the number of published bibliographic resources increases by 10,000 items every day. All items are interconnected with over 255,000 tags. The publishing status is reflected in the site's continuously updated tagline.
