Host selection, oviposition behaviour and leaf traits in a specialist willow sawfly on species of Salix (Salicaceae)
(Wiley, 2013-12)Plant genotype influences plant–herbivore interactions by affecting insect attraction, acceptance and development. Here we linked oviposition behaviour of the specialist willow sawfly Nematus oligospilus Förster (Hymenoptera: ... -
An assessor-specific Bayesian multi-threshold mixed model for analyzing ordered categorical traits in tree breeding
(Springer, 2013-12)Many traits of biological interest in tree breeding are assessed using more than two ordered discrete categories. These scores have a more or less arbitrary and subjective assignment by the assessors, which could lead to ... -
