Cortical Pyramidal Neuron Subtype Classification and Visual Response Diversity
… by measuring passive neuronal properties and responses to current injection using whole-cell patch-clamp recordings. A blind clustering algorithm exercised on the data revealed the presence of two principle classes of neurons.To address functional profiles, we recorded visual responses of …

Pollination in a changing world: function and resilience
… is a primary driver of terrestrial biodiversity loss, disrupting important ecosystem functions. Paradoxically, agriculture relies strongly on these same ecosystem functions. Animal-mediated pollination is critical for the functioning of natural and production systems, but is strongly …

Functional diversity enhances detection of ecosystem stability and resolution of predator-prey interactions within a multitrophic community
… factors that contribute to the decline of biodiversity which in turn has a negative impact on ecosystem function. There has been growing interest in understanding diversity’s role in the mechanisms behind ecosystem resilience with much attention focusing on how functional diversity, or the …

Molecular evolution of the p53 network in reptiles
… species have evolved unique organismal stress responses, we tested the related hypothesis that the evolutionary dynamics of, and mode of selection on, genes within the p53 network differs between reptiles and mammals, and that these differences may underlie the evolution of stress response …

Cross-scale resilience for organisations: A study of three geographic regions
… that monitoring slow variables such as biodiversity and proactively enhancing functional redundancy and response diversity fosters cross-scale resilience. By combining focal-scale bias and attention to slow changes, two distinct organisational profiles were identified, ‘focal-’ and …

Herbaceous species diversity, redundancy and resilience of Mopaneveld across different land-uses
… to which anthropogenic disturbances affect plant diversity and function of the herbaceous layer. This study aimed to quantify the effect of various land-use practices on herbaceous plant community structure, which included productivity (biomass) as well as richness, evenness and diversity at …

Response and resilience of estuarine benthic ecosystems to anthropogenic pressures
… and eutrophication; this thesis investigates the response and resilience of soft-sediment intertidal ecosystems to these two anthropogenic stressors. Increased SSC elevates water-column turbidity and reduces the light available for benthic primary producers that sustain estuarine food webs. In …
