Linking the hierarchical decisionmaking process of fruit choice and the phenotypic selection strength on fruit traits by birds
(Oxford University Press, 2017-08)
Aims: Animals in search of fleshy fruits forage mostly according to the number of available fruits and then select individual fruits based on reward quality or advertised subtle traits. This hierarchical pattern of fruit ...
Mapping QTLs on chicken chromosome 1 for performance and carcass traits in a broiler x layer cross
(Blackwell Publishing, 2006-04-01)
With the objective of mapping quantitative trait loci (QTLs) for performance and carcass traits, an F-2 chicken population was developed by crossing broiler and layer lines. A total of 2063 F-2 chicks in 21 full-sib families ...

Selection indexes using principal component analysis for reproductive, beef and milk traits in Simmental cattle
(2021)
Selection indexes in dual-purpose cattle should include beef, milk and reproductive traits. The principal component analysis is a multivariate technique that allows researchers to explore relationships between explanatory ...
Fruit selection by Andean forest birds: influence of fruit functional traits and their temporal variation
(Wiley Blackwell Publishing, Inc, 2016-09)
Fruit selection, i.e., the consumption of fruits disproportionately to their availability, results from the interaction between diet preferences and ecological factors that modify them. We assessed the importance of ...
Identification of superior genotypes and soybean traits by multivariate analysis and selection index
(Univ Federal Ceara, Dept Geol, 2018-07-01)
The selection of superior genotypes of soybean is a complex process, thus exploratory multivariate techniques can be applied to select genotypes analyzing the agronomic traits altogether, increasing the chance of success ...

Phenotypic, genetic and environmental parameters for traits related to femur bone integrity and body weight at 42 days of age in a broiler population
(Poultry Science Association Inc., 2015-11-01)
Intense selection among broilers, especially for performance and carcass traits, currently favors locomotion problems and bone resistance. Conducting studies relating to development and growth of bone tissue in broilers ...
Efficiency of a constrained linear genomic selection index to predict the net genetic merit in plants
(Genetics Society of America, 2019)
