Dormant Propagules In Demographic Studies: A Recurrent Bias And Potential Solutions, Federico Borghesi Jan 2023

Dormant Propagules In Demographic Studies: A Recurrent Bias And Potential Solutions, Federico Borghesi

Graduate Thesis and Dissertation 2023-2024

In the face of unprecedented anthropogenic change, we increasingly turn to emergent technologies and extensive data sets for solutions that complement much needed systemic changes in our societies. These technological solutions, however, must be approached with care. We must recognize and address biases in the way data has been accumulated. In demographic studies, dormant life stages, such as seed banks, and other cryptic factors have often been neglected. The potential consequences of these omissions have been extensively described in the literature. In the first chapter, I analyze patterns of seed bank omissions in demographic models, finding unjustified omissions are widespread …


Clay As A Control Technique For Karenia Brevis: Water Chemistry Dynamics And Physiological Impacts On Benthic Invertebrates, Victoria Devillier Jan 2023

Clay As A Control Technique For Karenia Brevis: Water Chemistry Dynamics And Physiological Impacts On Benthic Invertebrates, Victoria Devillier

Graduate Thesis and Dissertation 2023-2024

Clay-based compounds are globally the most advanced and widely used method of direct suppression of marine harmful algal blooms, and are currently undergoing investigation as an option to control Karenia brevis blooms in Florida. Before clay may be accepted for widespread use, there are multiple concerns and challenges that must be addressed regarding the environmental safety of this method, such as effects on water quality, the fate of toxins, and potential impacts of clay treatment to non-target organisms. To contribute to ongoing assessments of clay as a potential control method for K. brevis blooms, we conducted experiments with a formulation …
