- Abstract/Description
-
The Middle Miocene Climatic Optimum (MMCO) at ~ 16 Ma was the warmest interval during the Neogene. The peak of the MMCO in the North Pacific is marked by the appearance of the bivalve genus Kaneharaia (Bivalvia, Dosiniinae) in the high-latitude regions of Kamchatka and Alaska (55 –65°N). Specimens of Kaneharaia sp. were collected from two early middle Miocene high-latitude localities in the North Pacific – the Sea urchin Horizon of northwestern Kamchatka and the Narrow Cape Formation of...
Show moreThe Middle Miocene Climatic Optimum (MMCO) at ~ 16 Ma was the warmest interval during the Neogene. The peak of the MMCO in the North Pacific is marked by the appearance of the bivalve genus Kaneharaia (Bivalvia, Dosiniinae) in the high-latitude regions of Kamchatka and Alaska (55 –65°N). Specimens of Kaneharaia sp. were collected from two early middle Miocene high-latitude localities in the North Pacific – the Sea urchin Horizon of northwestern Kamchatka and the Narrow Cape Formation of Alaska. Middle Miocene Kaneharaia specimens were incrementally sampled for oxygen and carbon stable isotope records of seasonality. Results were compared with stable isotope profiles constructed for two Recent species of Dosinia from subtropical waters.

- Abstract/Description

This thesis focuses on evaluation of joint occurrence of extreme precipitation and streamflow events at several hydrologic structures in South Florida. An analysis of twelve years storm events and their corresponding peak streamflow events during wet and dry season including annual peaks considering two seasons was performed first. Dependence analysis using time series data of precipitation and streamflow was carried out next. The analysis included use of storm events with different temporal...
Show moreThis thesis focuses on evaluation of joint occurrence of extreme precipitation and streamflow events at several hydrologic structures in South Florida. An analysis of twelve years storm events and their corresponding peak streamflow events during wet and dry season including annual peaks considering two seasons was performed first. Dependence analysis using time series data of precipitation and streamflow was carried out next. The analysis included use of storm events with different temporal lags from the time of occurrence of peak streamflow events. Bi-variate joint probability was found to be appropriate to analyze the joint occurrence of events. Evaluation of joint exceedence probabilities under two phases of Atlantic multidecadal oscillation (AMO) influencing south Florida was also evaluated. All methodologies are evaluated for application using observations at several structures in the case study region to provide advances and valuable insights on joint extremes of precipitation and streamflows.

- Mangrove Morphological Change Across an Environmental Gradients: Implications for Competitive Ability in a Changing Climate.

In Florida, mangroves have responded to climate change by slowly migrating northward into traditional salt marsh habitat. However, little is understood about the relationships among mangrove growth form plasticity and environmental conditions. In addition, the effects of the mangrove northward expansion on pre-existing salt marsh communities are unknown, especially any influences of differences in tree morphology. The size, canopy structure, and root structure of the three mangrove species...
Show moreIn Florida, mangroves have responded to climate change by slowly migrating northward into traditional salt marsh habitat. However, little is understood about the relationships among mangrove growth form plasticity and environmental conditions. In addition, the effects of the mangrove northward expansion on pre-existing salt marsh communities are unknown, especially any influences of differences in tree morphology. The size, canopy structure, and root structure of the three mangrove species Rhizophora mangle, Avicennia germinans, and Laguncularia racemosa were measured at six sites along the east coast of Florida. Structural equation modeling was used to evaluate the multivariate relationships between environmental and biotic variables. Mangrove growth form varied widely with environmental variables. The results of this study suggest that R. mangle expansion into salt marsh may rely on interactions with salt marsh and shading as well as on climatic variables, which has implications for future mangrove expansion northward in Florida.

Scholars agree that global climate change is a major threat to the physical environment, affecting all aspects of life on the planet. However, the general public do not feel that climate change is a major risk or threat, especially to humans. It is important to understand the public’s perception and opinions of climate change as it affects and influences the creation and passing of climate change adaptation and mitigation policies.

Show moreScholars agree that global climate change is a major threat to the physical environment, affecting all aspects of life on the planet. However, the general public do not feel that climate change is a major risk or threat, especially to humans. It is important to understand the public’s perception and opinions of climate change as it affects and influences the creation and passing of climate change adaptation and mitigation policies. Specifically, little is known about public perceptions in regards to the greater health risk imposed by global climate change. This study examines the public's perception of health risks related to climate change in Broward County, Florida by using mixed methods. An online survey was conducted along with in-person interviews with the general public and a physician. The study found majority of respondents to believe climate change affects health, but lacked an understanding of how it is harmful to their health. It also found that gender affects their perceptions and political ideology appears to have an effect, but the effect of socioeconomic status on their perceptions were unable to be determined at this time. Broward is just developing policies to adapt and mitigate the health effects of climate change.

Global climate change stressors downscale to specific local vulnerabilities, requiring customized adaptation strategies. Southeast Florida has a high likelihood of sealevel rise impact to due to the low-lying porous limestone geology. High risk is coupled with high exposure due to high-valued coastal properties, productive ecosystems, and dense populations. Coastal populations are particularly at risk due to erosion, inundation and storm surge, but interior populations are also susceptible to...
Show moreGlobal climate change stressors downscale to specific local vulnerabilities, requiring customized adaptation strategies. Southeast Florida has a high likelihood of sealevel rise impact to due to the low-lying porous limestone geology. High risk is coupled with high exposure due to high-valued coastal properties, productive ecosystems, and dense populations. Coastal populations are particularly at risk due to erosion, inundation and storm surge, but interior populations are also susceptible to rising water tables and extended periods of inundation. All of these impacts are amplified by sea-level rise. Robust sea-level rise adaptation options require significant economic costs. If perceived risk does not adequately line up with actual risk, lack of funds and preparation will prevent implementation of the most effective strategies.
