This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
Animals living in groups are often linked to group or family members stronger than to other conspecifics, and form stronger coalitions (often based on genetic relatedness) within such groups. Effective cooperation within a group requires the preference for proximity of group members, suppression of aggression toward conspecifics, an ability to perceive and respond to social signals and to change (often synchronize) behavior accordingly. Birds have long been used for a number of investigations involving sensory perception, learning, feeding strategies and vocal communication. Recently, they have been proposed as ideal model species even for psychiatric disorders affecting social cohesion, suc...
The avian physiology section is now five years old. This special e-book is to commemorate this event. For this highlights issue celebrating the first five years of the Avian Physiology section, it was decided to focus on the top papers/reviews published. Table 1 lists the top fifteen papers/reviews based on either views or down-loads as a pdf. There is some agreement between the two lists. What is compelling is that of the top papers, all except one encompasses research conducted in domesticated birds, predominantly with chickens with one focused on turkeys. It is perhaps not unexpected that research on chickens dominates the top papers because of the following: - Chickens are commercially i...
The United Nations has recently released population projections suggesting that the global population will reach 9.7 billion by 2050 and exceed 11 billion by 2100. The increase in the world population may lead to food shortages, especially that of food protein. A variety of food protein alternatives have been developed and launched to the market to solve the problem of diminishing resources, particularly of land and water. In fact, animal protein has become a target in recent times for its greenhouse gas emissions. However, the UN has projected a steady increase in demand for poultry meat over the upcoming decades. The main demand will be from middle class and low-income families in particular and is due mainly to its high production efficiency for inexpensive, good-quality proteins. Nonetheless, due to limited resources, the poultry meat produced must be of high quality to ensure food security and minimize food waste.
