Spatial And Temporal Variation In Population Genetic Diversity In Seagrasses And The Implications For Resilience, Anna Maria Frouws

Theses: Doctorates and Masters

Seagrass ecosystems are highly productive and fulfil vital roles in the coastal environment as ecosystem engineers and keystone species. Unfortunately, anthropogenic pressures have resulted in a significant loss of seagrass habitat and associated ecosystem services. The complex and unpredictable nature of these pressures, and their increasing extent and intensity globally, makes resilience-based ecosystem management a valuable approach. Resilience-based management requires knowledge on processes enhancing ecosystem resilience and on actions supporting these processes. Genetic diversity, which is the allelic variation among individuals of a population, has been recognised as one of the pillars of resilient ecosystems. Genetic diversity within a population …

Developing A Weighted Model To Measure Knowledge Diffusion In A Tourism Destination Network, Hossein Raisi, Llandis Barratt-Pugh, Rodolfo Baggio, Gregory Willson, Sam Huang, Kourosh Esfandiar

Research outputs 2022 to 2026

Efficient knowledge transfer enhances tourism destination competitiveness. Multiple factors, however, affect knowledge transfer, making it a complex process to quantify. To address this complexity, we developed a quantitative tool by integrating a diffusion model with the major antecedents of knowledge transfer identified in the knowledge management literature. We applied this model in the Western Australian tourism industry and demonstrated its practicality. The proposed model provides a quantitative tool for destination management organizations to monitor, assess and improve the efficiency of knowledge diffusion within their tourism destinations. Such improved knowledge diffusion is critical in strengthening a destination's innovative capabilities and competitiveness.
