1. The distributions of large herbivores in protected areas and their surroundings are becoming increasingly restricted by changing land use, with adverse consequences for wildlife populations. 2. We analyse changes in ...
Genomic selection using regularized linear regression models: ridge regression, lasso, elastic net and their extensions.
(University of Nairobi, 2012)
BACKGROUND:
Genomic selection (GS) is emerging as an efficient and cost-effective method for estimating breeding values using molecular markers distributed over the entire genome. In essence, it involves estimating the ...

Colonization of wheat seedling leaves by Fusarium species as observed in growth chambers: a role as inoculum for head blight infection?
(2012)
Fusarium species involved in the Fusarium head blight complex in Western Europe were investigated for their potential to infect and colonize non-damaged wheat leaves and to produce conidia on senescing wheat leaves incubated ...
