Pituitary Prolactin Content of the Redwinged Blackbird at Pre-Breeding, Breeding and Post-Breeding Intervals
Environmental and physiological control of incubation behavior in wild and domesticated birds has been under investigation for the past thirty-five years. Most of the early literature deals with the non-passerines, specifically doves, pigeons and fowl. However, recent work has involved the order …

Ecology Of Non-Breeding And Breeding Crested Caracaras (Caracara cheriway) In Florida
… "caracara") is likely declining due to loss of breeding habitat. Consequently, management-oriented restrictions on landscape modification are applied where breeding occurs, but management rarely is extended beyond breeding areas. Focusing management on breeding areas can be effective if all …

Breeding for resistance to clover rot (Sclerotinia spp.) in red clover breeding (Trifolium pratense)
… on weather conditions. Moreover, resistance breeding is hampered by the lack of useable bio-tests and by the lack of knowledge on the genetic and phenotypic variation among Sclerotinia isolates. In this context, the objectives of this thesis were to analyse the phenotypic and genetic …

Breeding Waterfowl Populations in South Dakota
Breeding waterfowl in South Dakota were censused on 500 legal quarter sections within 125 clusters representing a proportional stratified random sample of 0.16 percent of the state area. Two breeding pair counts, one in May and second in June, were conducted each year on the sample units in 1973 …

Machine learning analytics for predictive breeding
<p>Prediction accuracies of genomic selection methods are affected by the quality of the phenotypic and genotypic data and by the use of appropriate analytic models in the training sets. This research focuses on the impact of data quality for ordinal traits. Ordinal scores of traits are typical for …
