The physiology and genetics behind fruiting efficiency: A promising spike trait to improve wheat yield potential
(Oxford University Press, 2021-05)
Fruiting efficiency (FE, grains per g of spike dry weight at anthesis) was proposed as a promising spike trait to improve wheat yield potential, based on its functional relationship with grain number determination and the ...
Alternative bayesian models for genetic evaluation of biometrical, physical, and morphological reproductive traits in nelore bulls
(Elsevier B.V., 2021-02-01)
Reproductive performance is one of the most important factors for the productive efficiency in beef cattle production. Biometric testicular and physical and morphological traits of the ejaculate are used to evaluate the ...
Religion and fertility patterns: Comparison of life history traits in Catholics and Protestants, Hallstatt (Austria) 1733-1908
(Cambridge University Press, 2020-02)
Catholicism and Protestantism have different ways of promoting the family unit that could influence survival and fertility at a population level. Parish records in the Austrian village of Hallstatt allowed the reconstruction ...
Sexually dimorphic traits and male fertility in a paper wasp
(Oxford Univ Press, 2020-07-01)
Females of many social Hymenoptera commit their reproductive potential to a single male; they mate once and never re-mate. Sexual selection theory predicts that under this regimen female precopulatory mate choice is crucial. ...
Maternal age influences on reproductive rates in Nile tilapia (Oreochromis niloticus)
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2015-04-01)
In this study we examined the effects of the maternal age on the fecundity (absolute and relative), egg production, and fertilization rates of Nile tilapia (Oreochromis niloticus). Females were divided into three groups: ...
Ranking of Nellore animals in cattle championships: genetic parameters and correlations with production traits
(Funpec-editora, 2014-01-01)
Records of 17,141 Nellore cattle participating in cattle championships, born from 1994-2009, were used to estimate genetic parameters between animal rank in cattle championships, evaluated from weaning to 36 months of age ...
Genome-enabled prediction of reproductive traits in Nellore cattle using parametric models and machine learning methods
(2021-02-01)
This study aimed to assess the predictive ability of different machine learning (ML) methods for genomic prediction of reproductive traits in Nellore cattle. The studied traits were age at first calving (AFC), scrotal ...
