Timing of Breeding in an Ecologically Trapped Bird
The American Naturalist, 2017In human-modified environments, organisms may prefer to use habitats where their reproductive performance is lower compared to alternative options. Many such ecological traps occur in seasonally changing environments. Although the timing of breeding has been shown to impact reproductive performance in a variety of organisms, it has never been ...

The article discusses the mapping of the domestic turkey genome by scientists at the U.S. Department of Agriculture (USDA) in an effort to help breeders produce a better quality of meat in greater and cheaper quantities.

Avian and Poultry Biology Reviews, 2002
Understanding of the physiology, molecular genetics and developmental biology of avian reproduction is essential for advances in the efficient breeding of birds for commercial gain. 2. Reproduction is controlled at the central nervous level by gonadotrophin releasing hormone-I (GnRH-I) and prolactin. 3.

Cooperative breeding is an unusual kind of social behaviour, found in a few hundred species worldwide, in which individuals other than the parents help raise young. Understanding the apparently altruistic behaviour of helpers has provided numerous challenges to evolutionary biologists.

Relationships Between Migration and Breeding Strategies in Arctic Breeding Birds
2003For successful breeding, good timing is of the utmost importance for birds inhabiting seasonal environments. Seasonal declines in reproductive success have been well documented in birds (e.g. Perrins 1970; Verhulst et al. 1995) and shown to be causally related to the timing of breeding (e.g. Verhulst et al. 1995; Brinkhof and Cave 1997).
