Bimodal trait distributions with large variances question the reliability of trait-based aggregate models
(Springer, 2016-12-01)
Functionally diverse communities can adjust their species composition to altered environmental conditions, which may influence food web dynamics. Trait-based aggregate models cope with this complexity by ignoring details ...
Selection and Complex Multigene Traits
(Wiley, 2013-05)
Phenotypic characters that display continuous variation are usually called ‘quantitative traits’ or ‘complex traits’. Alternatively, geneticists refer to them as ‘multigene traits’, because the underlying genetic architecture ...
Multivariate exploratory approach and influence of six agronomic traits on soybean genotypes selection
(Univ Federal Mato Grosso, 2016-07-01)
A comprehensive analysis for selection of superior genotypes can be useful and necessary. The aim of this study was to select soybean genotypes with superior agronomic traits through the use of multivariate exploratory ...
Associations of FASN gene polymorphisms with economical traits in Nellore cattle (Bos primigenius indicus)
(Springer, 2012-12-01)
The aim of this study was to identify molecular markers to be applied to marker-assisted selection. Three SNPs of the FASN gene were studied. PCR-RFLP was used for genotyping. The SNPs g.17924A > G, g.17860C > T and g.15603A ...

Directional, stabilizing, and disruptive trait selection as alternative mechanisms for plant community assembly
(Ecological Society of America, 2017-03-30)
How plant functional traits (e.g., seed mass) drive species abundance within communities remains an unsolved question. Borrowing concepts from natural selection theory, we propose that trait-abundance relationships can ...
Assessment of DGAT1 and LEP gene polymorphisms in three Nelore (Bos indicus) lines selected for growth and their relationship with growth and carcass traits
(Amer Soc Animal Science, 2010-02-01)
The aim of this study was to analyze LEP and DGAT1 gene polymorphisms in 3 Nelore lines selected for growth and to evaluate their effects on growth and carcass traits. Traits analyzed were birth, weaning, and yearling ...

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 ...
