Developmental plasticity in covariance structure of the skull: Effects of prenatal stress
(Wiley Blackwell Publishing, Inc, 2011-02)
Environmental perturbations of many kinds influence growth and development. Little is known, however, about the influence of environmental factors on the patterns of phenotypic integration observed in complex morphological ...
Evolutionary transition between bee pollination and hummingbird pollination in Salvia: Comparing means, variances and covariances of corolla traits
(Wiley Blackwell Publishing, Inc, 2019-04)
Covariation among traits can modify the evolutionary trajectory of complex structures. This process is thought to operate at a microevolutionary scale, but its long-term effects remain controversial because trait covariation ...
On identifiability of (co)variance components in animal models with competition effects
(Wiley Blackwell Publishing, Inc, 2008-12)
There is an increased interest in estimating the (co)variance components of additive animal models with direct and competition effects (AMC). However, some attempts to estimate the dispersion parameters in different animal ...
Estimates of covariance functions for growth of Nelore cattle applying a parametric correlation structure to model within-animal correlations
(2005-05-01)
A total of 20,065 weights recorded on 3016 Nelore animals were used to estimate covariance functions for growth from birth to 630 days of age, assuming a parametric correlation structure to model within-animal correlations. ...

Variance component estimates applying random regression models for test-day milk yield in Caracu heifers (Bos taurus Artiodactyla, Bovidae)
(Sociedade Brasileira de Genética, 2008-01-01)
Random regression models (RRM) were used to estimate covariance functions for 2,155 first-lactation milk yields of native Brazilian Caracu heifers. The models included contemporary group (defined as year-month of test and ...
