Competition in Arabidopsis thaliana (L.) Heynh., behaviour of Mimosa pudica L. and a new method to characterize roots demonstrated with Helianthus annuus L..

In this dissertation, I address 5 problems in the discipline of plant ecology: two problems in plant competition, two problems in plant behaviour and one problem in the phenotyping of plant roots. First, we directly test Darwin’s competition-relatedness hypothesis with a pairwise...

Exploring above- and belowground behavioural responses to nutrients and neighbours in wheat (Triticum aestivum L.)
DownloadSpring 2022
Taking in environmental information and responding in ways that maximize their ability to thrive and reproduce, plants exhibit behaviour through constant changes in biomass development and spatial distribution. Studies aiming to map this behaviour often use model plants like sunflowers and...

Relationships among diverse root foraging behaviours: understanding plant behavioural types
DownloadSpring 2014
Behaviours capture the functional response of plants to environmental factors. I explore behaviours for twenty co-occurring grassland species in response to common belowground environmental factors (competition, mycorrhizae, heterogeneous and high nutrients) and their relationship to plant...

All organisms, including plants, experience variability in the environment which puts pressure on organisms to evolve flexible responses. The study of these responses by organisms falls into the discipline of behavioural ecology. In this thesis, I am interested in the foraging behaviour of plant...
