Effects of environmental complexity on neurogenesis in the hippocampal dentate gyrus
… positively interfering with neurogenesis, the complexity of the environment appears to play a particularly striking role. Adult mice reared in an enriched environment produce more neurons and exhibit better performance in hippocampus-specific learning tasks. While the effects of complex …

The Effects of Environmental Complexity on Community Structure in Woodland Centipedes
… North Carolina is related to the structural complexity of these microhabitats.

Nature and nurture: genetic strains of broiler chickens housed in varying levels of environmental complexity
… growth. Using slower-growing strains or adding environmental complexity has been shown to improve broiler welfare. However, less is known about slow-growing broiler affective state, and the impact environmental enrichment will have on affective state in different strains. Poor health can cause …

Chicken or fish? Do environmental complexity and stocking density impact affective states of broiler chickens and rainbow trout?
… affective states are largely influenced by environmental condition, determining animal affective state can provide useful information on how to improve housing conditions in order to ensure positive experiences and good animal welfare. Cognitive processes are closely associated with …

The effects of environmental complexity upon the aggressive behaviour and growth of juvenile brown trout (Salmo trutta L.) and the carrying capacity of the environment
… tanks and aquaris to investigate the effects of environmental complexity upon the aggressive behaviour and growth of juvenile brown trout (Salmo trutta L.) and the carrying capacity of the environment. Natural materials and various structures were used to provide environmental complexity. …

Environmental attributes, strategy-making comprehensiveness and firm performance
… for this study. It was hypothesized that environmental complexity, or the number and heterogeneity of factors in the environment, and dynamism, or the degree of change, would impact the perceived uncertainty of the strategy maker, and further comprehensiveness in strategy-making. In …

TOPOLOGY-GUIDED MARKET-BASED MULTI-ROBOT TASK ALLOCATION
… to maintain efficiency as task density and environmental complexity increase, while decentralized methods face communication bottlenecks and lack topological awareness. In this study, we introduce a topology-guided market-based allocation framework designed to improve coordination efficiency …

Investigating the evolution of diversity and complexity of Prokaryotic gene regulatory networks using in silico models
… v) Multiple network solutions within identical environmental conditions are observed with the presence of stochastic basal gene expression. vi) Two attractor states, one with high, and one with low stochastic basal gene expression, are observed in networks which can evolve their levels of basal …

Characterizing Mental Workload in Physical Human-Robot Interaction Using Eye-Tracking Measures
… to learning and robot-difficulty but not environmental-complexity (collisions with objects in the task environment), and gaze-behavior measures were generally more sensitive to environmental-complexity. This research is the first to conduct a comprehensive analysis of mental workload in …

Genetic stigmergy: Framework and applications
… these systems often suffer from scalability and complexity issues due to the problems associated with mimicking the physics of pheromone diffusion. In this thesis, an alternative stigmergic framework called 'Genetic Stigmergy' is introduced. Using this framework, agents can indirectly share …

Autonomous Vehicle Perception Quality Assessment
… and LiDARs being commonly used sensors for environmental understanding and localization. However, there is a research gap in assessing the quality of AVs perception systems. To address this gap, this dissertation proposes a novel paradigm for evaluating AVs perception quality by studying the …

Autonomous UAV Navigation and Path Planning for Civil Infrastructures Inspection and Structural Health Monitoring
… different test scenarios with varying levels of environmental complexity. The simulation programming was accomplished using a meta-operating system library named Robot Operating System (ROS), and three path planning algorithms from the OMPL library were selected to assess their performance in …

Synthetic biology tools for sensing and evolving microbes: CRISPR-diagnostics and transposon-mediated genome re-wiring
… of host cells and investigate the impact of environmental complexity and genetic contingency on host-transposon interactions. Moving forwards, we envision this directed genome evolution platform being used to discover and optimize strains for biopharmaceutical applications, and as a …

Competitive interactions and community influences among invasive and native fishes at different spatial scales
… fishes on zooplankton, macroinvertebrates, and environmental variables. My results suggested that bluegill growth was density dependent, and bighead carp benefited from the presence of bluegill, which was likely due to shifts in nutrient cycling. To test whether the same influences occurred at a …

Evolutionary Genomics of Dominant Bacterial and Archaeal Lineages in the Ocean
… This project shows that differences in the environmental conditions found along the water column led to contrasting mechanisms of evolution and ultimately genome architectures. In Chapter 3, I assess the phylogenetic signal and congruence of marker genes commonly used for phylogenetic …

Developing a complexity leadership competency framework for the Governance and Administration Cluster of the South African Public Service
… organisations must strengthen their adaptive and complexity capacity to deal with environmental complexity through adopting a different leadership model that is characterised by distinct but complementary leadership functions. Complexity leadership theory (CLT) is thus adopted as an appropriate …

Investigation of somatomotor-sympathetic brain circuit abnormalities in two rat models featuring inborn differences in emotional behavior
… whether one potential therapeutic intervention, environmental enrichment during late childhood and adolescence, can improve emotional behavior disturbances and reverse premotor circuit alterations in bLR rats. Rearing young bLR rats in conditions with increased environmental complexity partially …
