Epigenetic Mechanisms As Drivers Of Environmental Responses In Stony Corals, Javier A. Rodriguez Casariego
Epigenetic Mechanisms As Drivers Of Environmental Responses In Stony Corals, Javier A. Rodriguez Casariego
FIU Electronic Theses and Dissertations
The current pace of anthropogenic global change is imposing unprecedented conditions to biological systems. Coral reef ecosystems are particularly sensitive to the rapid increase in thermal anomalies and the changes in water chemistry caused by global change. However, although their decline has been documented worldwide, there are signs suggesting that stony corals harbor greater phenotypic plasticity than previously expected, sparking the interest in the study acquired non-genetic modifications (e.g., epigenome, microbiome) potentially increasing their resilience to global change, and constituting one of the main targets for intervention.
Epigenetics constitutes an exciting frontier to understand how the environment influences the regulation …
The Metabolic Ecology Of Tropical Amphibians Across An Elevational Gradient In The Andes Of Southeastern Peru, Michael R. Britton
The Metabolic Ecology Of Tropical Amphibians Across An Elevational Gradient In The Andes Of Southeastern Peru, Michael R. Britton
FIU Electronic Theses and Dissertations
Metabolism is a fundamental biological process that determines the rate at which organisms process energy and materials, and determines the availability of resources for growth, maintenance and reproduction. Metabolic rates scale across levels of organization from cells to whole organisms and affect population, community, and ecosystem processes. Anthropogenic climate change and other environmental changes are predicted to have major impacts on the energetics of organisms that will be mediated through metabolic physiology. Tropical ectotherms, such as amphibians, may be among the most vulnerable to metabolic impacts of climate change as a result of being ectothermic, having high thermal sensitivity, and …
Survival At The Summits: Amphibian Responses To Thermal Extremes, Disease, And Rapid Climate Change In The High Tropical Andes, Kelsey E. Reider
Survival At The Summits: Amphibian Responses To Thermal Extremes, Disease, And Rapid Climate Change In The High Tropical Andes, Kelsey E. Reider
FIU Electronic Theses and Dissertations
Understanding biological responses to climate change is a primary concern in conservation biology. Of the ecosystems being rapidly impacted by climate change, those in the high-elevation tropics are among the most poorly studied. The tropical Andean biosphere includes record elevations above 5000 meters, where extreme environmental conditions challenge many organisms. In the Cordillera Vilcanota of southern Peru, frogs including Pleurodema marmoratum and Telmatobius marmoratus have expanded their ranges to 5244 – 5400 m into habitats created by glacial recession, making them among the highest recorded amphibians on Earth. To understand how hydrologic alterations from loss of glacial meltwater and climatic …
Reimagining Movements: Towards A Queer Ecology And Trans/Black Feminism, Gabriel Benavente
Reimagining Movements: Towards A Queer Ecology And Trans/Black Feminism, Gabriel Benavente
FIU Electronic Theses and Dissertations
This thesis seeks to bridge feminist and environmental justice movements through the literature of black women writers. These writers create an archive that contribute towards the liberation of queer, black, and transgender peoples.
In the novel Parable of the Talents, Octavia Butler constructs a world that highlights the pervasive effects of climate change. As climate change expedites poverty, Americans begin to blame others, such as queer people, for the destruction of their country. Butler depicts the dangers of fundamentalism as a response to climate change, highlighting an imperative for a movement that does not romanticize the environment as heteronormative, but …
Effects Of Catastrophic Seagrass Loss And Predation Risk On The Ecological Structure And Resilience Of A Model Seagrass Ecosystem, Robert J. Nowicki
Effects Of Catastrophic Seagrass Loss And Predation Risk On The Ecological Structure And Resilience Of A Model Seagrass Ecosystem, Robert J. Nowicki
FIU Electronic Theses and Dissertations
As climate change continues, climactic extremes are predicted to become more frequent and intense, in some cases resulting in dramatic changes to ecosystems. The effects of climate change on ecosystems will be mediated, in part, by biotic interactions in those ecosystems. However, there is still considerable uncertainty about where and how such biotic interactions will be important in the context of ecosystem disturbance and climactic extremes.
Here, I review the role of consumers in seagrass ecosystems and investigate the ecological impacts of an extreme climactic event (marine heat wave) and subsequent widespread seagrass die-off in Shark Bay, Western Australia. Specifically, …
The Effects Of Climate Warming On Plant-Herbivore Interactions, Nathan Lemoine
The Effects Of Climate Warming On Plant-Herbivore Interactions, Nathan Lemoine
FIU Electronic Theses and Dissertations
Rising temperatures associated with climate change will alter the fundamental physiological processes of most ectothermic species. Drastic changes in catabolic and anabolic reaction rates exert strong effects on growth, reproduction, and consumption rates that cascade up through all levels of the biological hierarchy. This dissertation determined how climate warming might alter the important relationship between plants and insect herbivores, as mediated through changes in herbivore physiology. Consumption and fitness increased with temperature for almost all consumers. However, all consumers also exhibited a critical temperature, beyond which consumption declined rapidly through metabolism continued to increase. This mismatch in metabolic demands and …
Arctic Ecosystem Responses To Changes In Water Availability And Warming: Short And Long-Term Responses, Paulo C. Olivas
Arctic Ecosystem Responses To Changes In Water Availability And Warming: Short And Long-Term Responses, Paulo C. Olivas
FIU Electronic Theses and Dissertations
Arctic soils store close to 14% of the global soil carbon. Most of arctic carbon is stored below ground in the permafrost. With climate warming the decomposition of the soil carbon could represent a significant positive feedback to global greenhouse warming. Recent evidence has shown that the temperature of the Arctic is already increasing, and this change is associated mostly with anthropogenic activities. Warmer soils will contribute to permafrost degradation and accelerate organic matter decay and thus increase the flux of carbon dioxide and methane into the atmosphere. Temperature and water availability are also important drivers of ecosystem performance, but …
