Atlantic forest fragmentation and genetic diversity of an isolated population of the Blue-manakin, Chiroxiphia caudata (Pipridae), assessed by microsatellite analyses
(2006-03-01)
Habitat fragmentation is predicted to restrict gene flow, which can result in the loss of genetic variation and inbreeding depression. The Brazilian Atlantic forest has experienced extensive loss of habitats since European ...
Environmental and genetic factors affecting the weaning-estrus interval in sows
(Funpec-editora, 2011-01-01)
We examined the effects of environmental and genetic factors on the weaning-to-estrus interval (WEI) in sows. In order to perform the analyses of the environmental factors, 8104 observations of the 1st to the 6th WEI were ...

Genetic parameters and trends of morphometric traits of GIFT tilapia under selection for weight gain
(Univ Sao Paolo, 2014-07-01)
The main factor considered in breeding programs for fish is growth, which can be assessed in terms of a gain in either weight or body measurements. This study was undertaken to evaluate the morphometric traits of GIFT ...
Genetic diversity in the endangered tropical tree, Guaiacum sanctum (Zygophyllaceae)
(2010)
Fragmentation of tropical forests has changed continuous tropical landscapes into a network of poorly connected fragments, reducing population sizes and potentially increasing genetic isolation. This study quantifies genetic ...
Reduced-rank estimation of genetic parameters for egg production traits and cluster analyses with predicted breeding values
(Taylor & Francis As, 2018-04-03)
The aims of this study were to compare the suitability of the multi-trait (MUT) model to estimate genetic parameters with that of 13 reduced-rank principal component models (PC1 to PC13), and then to explore the additive ...
Genetic gain in the selection by multi-effects index in open-pollinated progenies of Eucalyptus grandis Hill ex Maiden
(Ipef-inst Pesquisas Estudos Florestais, 2015-03-01)
In Brazil, Eucalyptus grandis Hill ex Maiden is widely used for commercial reforestation, especially for production of pulp, paper and energy. Its genetic variability is being explored in tree improvement programs for over ...
Genetic parameter estimates for buffalo milk yield, milk quality and mozzarella production and Bayesian inference analysis of their relationships
(Funpec-editora, 2010-01-01)
Buffalo milk has excellent physical and chemical qualities as a consequence of the high percentage of constituents. This milk property is desirable for the dairy industry because it facilitates manufacture of mozzarella ...
