Social plasticity within and across generations : testing the role of plasticity in rapid evolution in field cricket Teleogryllus oceanicus
(2021-06-30) - ThesisThe field of evolutionary biology lacks a full understanding of how phenotypic plasticity influences adaptive evolution, despite over a century of research effort. One under-studied question within this topic is whether ... -
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 ... -
Rhythmically repeated patterns of pulsed vocalizations in wild narwhals (Monodon monoceros)
(2018-12-06) - ThesisSequences of vocalizations are indicative of communicative complexity. However, relative to birds and terrestrial mammals, the extent to which marine mammals use vocal sequences is not well understood. I provide the ...
