Increasing Atmospheric Humidity And Co2 Concentration Alleviate Forest Mortality Risk, Yanlan Liu, Anthony J. Parolari, Mukesh Kumar, Chang-Wei Huang, Gabriel Katul, Amilcare Porporato Sep 2017

Increasing Atmospheric Humidity And Co2 Concentration Alleviate Forest Mortality Risk, Yanlan Liu, Anthony J. Parolari, Mukesh Kumar, Chang-Wei Huang, Gabriel Katul, Amilcare Porporato

Civil and Environmental Engineering Faculty Research and Publications

Climate-induced forest mortality is being increasingly observed throughout the globe. Alarmingly, it is expected to exacerbate under climate change due to shifting precipitation patterns and rising air temperature. However, the impact of concomitant changes in atmospheric humidity and CO2 concentration through their influence on stomatal kinetics remains a subject of debate and inquiry. By using a dynamic soil–plant–atmosphere model, mortality risks associated with hydraulic failure and stomatal closure for 13 temperate and tropical forest biomes across the globe are analyzed. The mortality risk is evaluated in response to both individual and combined changes in precipitation amounts and their seasonal …

Rethinking Force Majeure In Public International Law, Myanna Dellinger Sep 2017

Rethinking Force Majeure In Public International Law, Myanna Dellinger

Pace Law Review

Climate change is one of today’s most significant and complex problems. The number and level of severity of extreme weather events is increasing rapidly around the world. One year after the next, we learn that heat records have been broken once again. Climate change has been traced to a wide range of severe problems around the world, ranging from the obvious damage caused by hurricanes, floods, extreme rainfall, prolonged droughts, wildfires and a host of other weather-related issues to the perhaps less obvious such as physical and mental illnesses, “civil unrest, riots, mass migrations and perhaps wars caused by water …

Climate change is a well-documented driver of both wildlife extinction and disease emergence, but the negative impacts of climate change on parasite diversity are undocumented. We compiled the most comprehensive spatially explicit data set available for parasites, projected range shifts in a changing climate, and estimated extinction rates for eight major parasite clades. On the basis of 53,133 occurrences capturing the geographic ranges of 457 parasite species, conservative model projections suggest that 5 to 10% of these species are committed to extinction by 2070 from climate-driven habitat loss alone. We find no evidence that parasites with zoonotic potential have a …

Increasing concern about the impacts of climate change on ecosystems is prompting ecologists and ecosystem managers to seek reliable projections of physical drivers of change. The use of global climate models in ecology is growing, although drawing ecologically meaningful conclusions can be problematic. The expertise required to access and interpret output from climate and earth system models is hampering progress in utilizing them most effectively to determine the wider implications of climate change. To address this issue, we present a joint approach between climate scientists and ecologists that explores key challenges and opportunities for progress. As an exemplar, our focus …

Warming And Elevated Co2 Alter The Suberin Chemistry In Roots Of Photosynthetically Divergent Grass Species, Vidya Suseela, Nishanth Tharayil, Elise Pendall, Apparao M. Rao Sep 2017

Warming And Elevated Co2 Alter The Suberin Chemistry In Roots Of Photosynthetically Divergent Grass Species, Vidya Suseela, Nishanth Tharayil, Elise Pendall, Apparao M. Rao

Publications

A majority of soil carbon (C) is either directly or indirectly derived from fine roots, yet roots remain the least understood component of the terrestrial carbon cycle. The decomposability of fine roots and their potential to contribute to soil C is partly regulated by their tissue chemical composition. Roots rely heavily on heteropolymers such as suberins, lignins and tannins to adapt to various environmental pressures and to maximize their resource uptake functions. Since the chemical construction of roots is partly shaped by their immediate biotic/abiotic soil environments, global changes that perturb soil resource availability and plant growth could potentially alter …

Long-Term Changes In A Spatially Subsidized Insular Ecosystem In The Archipelago Of Bahía De Los Ángeles, Baja California, Mexico, Thais Fournier Aug 2017

Long-Term Changes In A Spatially Subsidized Insular Ecosystem In The Archipelago Of Bahía De Los Ángeles, Baja California, Mexico, Thais Fournier

Theses

Interactions between climate change and the processes that structure coastal communities are poorly understood.Long – term weather patterns that include extreme events (e.g., El Niño Southern Oscillation, or “ENSO”) allow us to test hypotheses of how changes in weather (e.g., precipitation) will influence communities over long time frames. One system that is particularly vulnerable to climate changes is the coastal ecotone, which occupies 8% of the earth’s surface. A large exchange of resources (spatial subsidies) link habitats across this ocean – land interface, often with dramatic consequences for the recipient systems. Spatial subsidies such as marine input influence …

Rethinking Urban Green Infrastructure As A Means To Promote Avian Conservation, Allen Lau Aug 2017

Rethinking Urban Green Infrastructure As A Means To Promote Avian Conservation, Allen Lau

Master's Projects and Capstones

There is an under-recognized potential for cities to use urban green infrastructure to contribute to avian biodiversity conservation. At the global scale, climate change and growing urbanization are primary global drivers leading to decline and homogenization in world bird populations. Birds are fundamental and intricate species in ecosystems, and even in urban areas, act as indicator and regulator species contributing to healthy ecosystem function. While many cities have recognized the economic and social benefits associated with green spaces, such as the vast benefits ecosystem services provide to the urban dweller, the use of green spaces to concurrently contribute to avian …

Risk And The Response To Sea Level Rise In South Florida, Galen Treuer Jul 2017

Risk And The Response To Sea Level Rise In South Florida, Galen Treuer

Open Access Dissertations

South Florida’s low elevation, intensive urban development, and delicate ecosystems make it vulnerable to sea level rise. A gap exists between the current policies local governments in South Florida pursue and adaptation that could significantly reduce their exposure to climate change risks. One reason for this gap is that climate adaptation requires a transition away from the status quo, and barriers impede change. This dissertation presents three studies that aim to help communities in the region embrace and address their climate change risks. Chapter 2 reports the findings of an immersive simulation experiment that accelerates South Florida homeowners through thirty-five …

Linking The Biological Impacts Of Ocean Acidification On Oysters To Changes In Ecosystem Services: A Review, Anaëlle J. Lemasson, Stephen Fletcher, Jason M. Hall-Spencer, Antony M. Knights Jul 2017

Linking The Biological Impacts Of Ocean Acidification On Oysters To Changes In Ecosystem Services: A Review, Anaëlle J. Lemasson, Stephen Fletcher, Jason M. Hall-Spencer, Antony M. Knights

School of Biological and Marine Sciences

Continued anthropogenic carbon dioxide emissions are acidifying our oceans, and hydrogen ion concentrations in surface oceans are predicted to increase 150% by 2100. Ocean acidification (OA) is changing ocean carbonate chemistry, including causing rapid reductions in calcium carbonate availability with implications for many marine organisms, including biogenic reefs formed by oysters. The impacts of OA are marked. Adult oysters display both decreased growth and calcification rates, while larval oysters show stunted growth, developmental abnormalities, and increased mortality. These physiological impacts are affecting ecosystem functioning and the provision of ecosystem services by oyster reefs. Oysters are ecologically and economically important, providing …

Friends Or Foes? The Problem Of South Florida’S Invasive Mangroves, Kelly J. Cox, Rafael J. Araújo

Pace Environmental Law Review

A recent global review on the impacts of climate change on mangroves concluded that different regions will experience varying degrees of impacts due to the variability of expected changes in climate (shifts in precipitation, frequency and intensity of storms, droughts, sea level rise, change of ocean currents, increases in CO2 concentrations, etc.) and the variety of types and mangrove assemblages growing in these regions, including different species composition of mangrove forests. In North America and the Caribbean, these changes are dependent upon a predicted higher frequency (and intensity) of tropical storms, sea level rise, changes in patterns of precipitation, and …

Making Old Stories New In The Anthropocene: Reading, Creating, And The Cosmological Imagination In Darren Aronofsky's Noah, Kellianne Houston Matthews Jun 2017

Making Old Stories New In The Anthropocene: Reading, Creating, And The Cosmological Imagination In Darren Aronofsky's Noah, Kellianne Houston Matthews

Theses and Dissertations

This thesis examines Darren Aronofsky's 2014 film Noah as a pattern for metafictionalizing narratives into thinking stories as we confront the uncertainty and challenges of the Anthropocene. While Ecocriticism has sought for the development and promotion of nature writing and environmentally oriented poetry and fiction- "new stories" that will shape a stronger environmental ethic"”it has placed too much responsibility for the environmental imagination on what we read rather than on the more important question of how we read. My argument addresses the readerly responsibilities that, if met, have the power to transform old stories and old habits of mind into …

Understanding The Complex Relationships Between Climate, Vegetation, And Foraging Behavior Of A Climate-Sensitive Alpine Mammal In Order To Explain Patterns Of Persistence, Evan Cole

Master's Projects and Capstones

Mountain ecosystems offer substantial ecosystem services but are highly sensitive to climate change. The American pika (Ochotona princeps) serves as an indicator species of climate change and a model organism for studying its impacts on mountain mammals. Certain aspects of plant community composition and structure can function as predictors of pika distribution, but understanding the links between climate, forage quality, and foraging behavior is necessary to identify the mediating mechanism. Pika foraging pressure help shape the local plant community, which can confound modeling efforts and must be considered when evaluating the influence of vegetation on pika persistence. Plant …

Environmental Controls On The Reassembly Of Symbiodinium Communities In Reef Corals Following Perturbation: Implications For Reef Futures Under Climate Change, Rivah Norwood Winter

Open Access Dissertations

The persistence of coral reef ecosystems, valued in the hundreds of billions of dollars annually, relies on the survival and growth of the coral colonies that build the habitat. However, these ecosystem engineers are threatened by a host of stressors, including warming ocean temperatures due to global climate change. Anomalously high sea surface temperatures can result in coral bleaching, the breakdown in the obligate symbiosis between the coral host and its community of single-celled, dinoflagellate algae in the genus Symbiodinium. Bleaching stress that is too prolonged or too severe can result in coral mortality, and increasingly frequent and severe bleaching …

Searching For Antibiotic Resistance Genes In A Pristine Arctic Wetland, Krystalle S. Diaz, Virginia I. Rich, Jean E. Mclain May 2017

Searching For Antibiotic Resistance Genes In A Pristine Arctic Wetland, Krystalle S. Diaz, Virginia I. Rich, Jean E. Mclain

Journal of Contemporary Water Research and Education

Antibiotics are the foundation of modern medicine, and the sustainability of antibiotic use depends on overcoming the challenge of antibiotic resistance (AR). This may be extremely difficult, given that antibiotic production by environmental microbiota is a natural process and AR is widespread in nature. AR has been shown to spread readily and quickly, as well as to exist in the absence of anthropogenic forcing (i.e., the application of antibiotics by humans). This study compared a range of approaches to identify AR gene sequences in microbial community genomes in three habitats (Palsa, Bog, and Fen) across a permafrost thaw gradient in …

Reduced Phytoplankton And Zooplankton Diversity Associated With Increased Cyanobacteria In Lake Champlain, Usa, Katelyn A. Bockwoldt, Emily R. Nodine, Timothy B. Mihuc, Angela D. Shambaugh, Jason D. Stockwell

Journal of Contemporary Water Research and Education

Anthropogenic inputs of nutrients threaten water quality around the world, causing eutrophication and altering phytoplankton communities. In freshwater systems, certain physiochemical conditions, including high TP, low TN:TP, and warm temperatures, can lead to problematic cyanobacteria blooms. Cyanobacteria can decrease phytoplankton diversity and phytoplankton diversity has been positively linked to zooplankton diversity, suggesting that cyanobacteria may have indirect negative effects on zooplankton diversity. Using monitoring data from Lake Champlain, we tested three hypotheses: (1) cyanobacteria density and phytoplankton diversity are inversely related; (2) phytoplankton diversity and zooplankton diversity are positively related; and by extension (3) cyanobacteria density and zooplankton diversity are …

The Extinction Of The Carolina Parakeet And Multiple Dimensions Of Global Parrot Biodiversity, Kevin R. Burgio May 2017

The Extinction Of The Carolina Parakeet And Multiple Dimensions Of Global Parrot Biodiversity, Kevin R. Burgio

Doctoral Dissertations

The study of the ecology of a species has traditionally ceased when that species goes extinct, despite the benefit to current and future generations of potential findings. We used the Carolina parakeet to develop a framework investigating the distributional limits, migratory habits, and extinction process as a means to recover important information. We developed a comprehensive database of every known occurrence of this iconic species. Using a combination of environmental niche modeling and extinction estimating analyses, our results demonstrate that the Carolina parakeet’s range was smaller than previously believed, the eastern and western subspecies occupied different niches with broad geographic …

Summer Precipitation Occurrence Effect On Two Passerine Species In Thule, Greenland, Sara E. Baugh

Celebration of Learning

Climate change is occurring at a faster rate in the Arctic than the rest of the globe, causing temperature rises at twice the rate of the global average and increased summer precipitation in the form of rain. These precipitation events are predicted to affect migratory bird species that breed throughout the Arctic. Increased occurrence of heavy rainstorms indirectly affect bird populations by impacting distribution and abundance of food supply, and directly by increasing mortality rates of juveniles. Studies conducted on bird species throughout the low Arctic regions; have shown that it is not the total precipitation of a breeding season …
