Molecular mechanisms and functional consequences of chromatin binding by the human cytomegalovirus proteins IE1 and pUL83
(University of St Andrews, 2022-06-15) - ThesisInterferons (IFN) are an essential component of the vertebrate innate immune system against viruses and other pathogens. Human Cytomegalovirus (HCMV), like other viruses, has developed strategies to evade the host IFN ... -
An experimental investigation of the evolutionary dynamics of phenotypic plasticity under relaxed selection in threespine sticklebacks (Gasterosteus aculeatus)
(University of St Andrews, 2022-06-27) - ThesisHere I provide an overview of the ways in which phenotypic plasticity is suggested to be relevant to evolutionary dynamics, and examine the various predicted dynamics of plastic traits in novel environments. Following on ... -
Structure and mechanism of two type III CRISPR defence nucleases activated by cyclic oligoadenylate
(2022-06-15) - ThesisProkaryotes have a wide range of antiviral strategies to defend against invading mobile genetic elements (MGEs). Type III CRISPR-Cas systems typically synthesise cyclic oligoadenylate (cOA) second messengers upon binding ... -
Exploring mixed-species grouping effects through antipredator mechanisms
(University of St Andrews, 2022-06-15) - ThesisPredation is an important selective force for prey organisms, which have also developed different antipredator adaptions. Individuals of many animal species live in the group, which is generally believed to offer prey ... -
Social behaviour and learning in archerfish
(University of St Andrews, 2021-06-30) - ThesisLearning is crucial to making behavioural adjustments and fish are adept at using the behaviour of others to more easily find and discriminate between different sources of food, recognise novel predators and other challenges ...
