Avian life in a seasonally arid tropical environment : adaptations and mechanisms in breeding, molt and immune function
(University of St Andrews, 2019-06-14) - ThesisThere is a growing appreciation of the diversity and uniqueness of tropical organisms, but evidence about the selection pressures that shape this diversity remains sketchy. In this thesis, I investigated how variation in ... -
Genome-based approaches for identification of avirulence genes in potato cyst nematodes
(University of St Andrews, 2019-12-03) - ThesisThe use of natural resistance is the most effective way to control the potato cyst nematodes Globodera pallida and G. rostochiensis. Although pathotypes of the latter species can now be fully controlled, control of G. ... -
Molecular analysis of the eggshell and cuticle surface of the potato cyst nematode, Globodera rostochiensis
