The wood anatomy of Gymnanthes klotzschiana was studied, to assess whether there are variations in the secondary xylem under different geopedological conditions. The species is dominant in subtropical alluvial forests and can be established in different ecological conditions, especially regarding soil water regime. Wood samples were collected in the plain of the Iguaçu River, in Paraná, Brazil, encompassing three geopedological conditions: gleysol, fluvisol and psamment, characterized by varying degrees of water saturation, ranging from very poorly drained to heavily drained. Considerable intraspecific variations were found in the xylem in response to geopedological conditions. Most of the variation occurs in attributes related to the biomechanical and hydraulic functions (e.g. fibers and vessels), with cells smaller in gleysol, larger in fluvisol and intermediate in psamment. For some variables, the xylem has similar responses in conditions of water deficit and permanent water saturation, indicating a probable influence of physiological drought. The phenotypic plasticity of the species explains its high adaptability to the selective and variable conditions of riparian environments. The study contributes to understanding the species’ ecological responses, highlighting its relevance as a keystone species in the dynamic and fragile ecosystems of the floodplains, fundamental for the maintenance of many ecosystem services. |

Studies investigating the use of random regression models for genetic evaluation of milk production in Zebu cattle are scarce. In this study, 59,744 test-day milk yield records from 7,810 first lactations of purebred dairy Gyr (Bos indicus) and crossbred (dairy Gyr × Holstein) cows were used to compare random regression models in which additive genetic and permanent environmental effects were modeled using orthogonal Legendre polynomials or linear spline functions. Residual variances were modeled considering 1, 5, or 10 classes of days in milk. Five classes fitted the changes in residual variances over the lactation adequately and were used for model comparison. The model that fitted linear spline functions with 6 knots provided the lowest sum of residual variances across lactation. On the other hand, according to the deviance information criterion (DIC) and Bayesian information criterion (BIC), a model using third-order and fourth-order Legendre polynomials for additive genetic and permanent environmental effects, respectively, provided the best fit. However, the high rank correlation (0.998) between this model and that applying third-order Legendre polynomials for additive genetic and permanent environmental effects, indicates that, in practice, the same bulls would be selected by both models. The last model, which is less parameterized, is a parsimonious option for fitting dairy Gyr breed test-day milk yield records. |
