Illuminating The Drivers Of Genomic Diversification In Lamprologine Cichlids Of The Lower Congo River, Naoko P. Kurata

Dissertations, Theses, and Capstone Projects

Freshwater fishes are extraordinarily diverse, considering their available habitats represent a tiny proportion of the earth’s surface. Rivers connect heterogeneous habitats in a linear form and provide excellent simplified models to understand how aquatic biodiversity evolves. In particular, the lower Congo River (LCR) in west Central Africa consists of a dynamic hydroscape exhibiting extraordinary aquatic biodiversity, endemicity, and morphological and ecological specialization. This system is thus an excellent natural laboratory for understanding complex speciation and population diversification processes. In my research, I explore various drivers of diversification, and adaptive evolution in rheophilic lamprologine cichlids endemic to the LCR, including Lamprologus …

Effects Of Climate Change On Human Health, Sara El Houzaly, Richa Gupta

The effects of climate change are evident worldwide as average global land and air temperatures have been rising, glaciers and ice sheets are shrinking with the concomitant rise in sea levels, extreme weather events have become more frequent, and oceans are warming and acidifying. Humanity is facing a big environmental challenge which not only impacts our habitat but will also have ramifications on our health. The present review describes a detailed examination of the scientific evidence proving the relationship between climate change and various fatal human diseases in different geographical regions. Our findings indicate that variations in the patterns of …

How Will Climate Change Affect The Future, Ashanti K. Belone, Farrukh Zia

Publications and Research

Climate Change has played a massive role in the habitat of us earth dwellers and the animals that co-exists with us. I believe that essentially climate change plays a massive role because this can dictate whether or not the earth is habitable and if a need for evacuation is necessary. Many might believe that climate change only refers to the rising temperature but that’s just the icing on the cake. Earth is a system that is very much connected, this means that changes in one area will set off a chain reaction allowing these changes to happen in many other …

Lost At Sea, Anny Oberlink

Capstones

At the end of World War I and World War II, in a new era of peace, nations confronted an unprecedented logistical problem: millions of tons of unexploded ordnance—once a wartime boon—had become a peacetime burden. Faced with a mandate to dispose of excess munitions, militaries turned to dumping their stockpiles into the sea. But now a complex and urgent issue is emerging. Increasingly, as industry looks to build offshore—wind power turbines, internet cables, oil pipelines—they are facing a potential peril: millions of tons of unexploded bombs and ammunition that are lying on the ocean floor can explode or leak …

Three Lc-Ms Plant Metabolomics Studies Of Hop (Humulus) Species: Wild H. Neomexicanus, Drought Stress, And Agricultural Terroir, Taylan Morcol

Dissertations, Theses, and Capstone Projects

The hop plant (Humulus L., Cannabaceae) is a dioecious, perennial, twining vine with a long history of human use. Nowadays, hop plants are generally grown for their inflorescences (“cones”), which are used in brewing for their phytochemical metabolites. Many of these metabolites are involved in plant stress response and communication. Genetics and environment are two major factors that affect plant metabolism. In three separate metabolomics studies, this project examined the effects of both genetic and environmental factors on hop phytochemistry.

In the first study, 23 hop genotypes were grown in two different locations in the Pacific Northwest region of …

Intangible Cultural Heritage: A Benefit To Climate-Displaced And Host Communities, Gül Aktürk, Martha B. Lerski

Publications and Research

Climate change is borderless, and its impacts are not shared equally by all communities. It causes an imbalance between people by creating a more desirable living environment for some societies while erasing settlements and shelters of some others. Due to floods, sea level rise, destructive storms, drought, and slow-onset factors such as salinization of water and soil, people lose their lands, homes, and natural resources. Catastrophic events force people to move voluntarily or involuntarily. The relocation of communities is a debatable climate adaptation measure which requires utmost care with human rights, ethics, and psychological well-being of individuals upon the issues …

A Crisis Of Kelp, Rachel L. Sherman

Capstones

Along with insects and lab-grown meat, for years seaweed has been lauded as a sustainable “food of the future” by the U.N. Food and Agricultural Organization. As the world increasingly turns to alternative foods in pursuit of a healthier Earth, seaweed has all the makings of an ecological savior. It’s plentiful — seaweeds and ocean algae make up roughly nine tenths of all the plant life on Earth — it’s cheap to harvest and get to market, packed with nutrition, and keeps oceans clean, absorbing more carbon dioxide and releasing more oxygen than the world’s rainforests.

But outside of Japanese …

What If The Key To Climate Change Is Hiding Under The Sea?, Shira Feder

Capstones

“We know more about outer space than we do the ocean,” says Vicki Ferrini, a research scientist at Columbia University with over 20 ocean expeditions under her belt. And as the woman leading Seabed 2030, the charge to map the world’s oceans—which are 85% unexplored—she knows how vital this is to combat climate change and exactly how she’s going to do it.

The Living Archive In The Anthropocene, Nora Almeida, Jen Hoyer

Publications and Research

This paper presents the concept of the living archive as a system which reflects how social behavior and cultural production are part of the Anthropocene. The authors explore how dominant narratives of both the Anthropocene and the archive work to consolidate power and maintain cultural and disciplinary divisions. The authors refute conceptions of the Anthropocene as a purely biophysical phenomenon that is alienated from cultural practice and of the archive as a comprehensive and nostalgic space. They then introduce the living archive as an alternative representational, creative, and reactive space and illustrate how the living archive can intervene in ecological …

Nature's Queer Negativity: Between Barad And Deleuze, Steven Swarbrick

Publications and Research

This essay offers a critique of the vitalist turn in queer and ecological theory, here represented by the work of Karen Barad. Whereas Barad advances an image of life geared towards meaningful connection with others, human and nonhuman, Deleuze advances an a-signifying ontology of self-dismissal. The point of this essay isn’t to separate their two views, but to draw out the consequences of their entanglement. Insofar as Barad’s work conceptualizes life (and art) as a vitalizing encounter, it cannot, this essay argues, account for the queer negativity at play in environmental politics, including the politics of climate change.

Biodiversity Of Medicinal Plants In The Highlands: Problems And Perspectives, Vyacheslav Dushenkov

Publications and Research

Climate change is affecting medicinal plants around the world and could ultimately lead to losses of some key species, in particular species endemic to a region and causing plants to migrate to new ranges. As the situation unfolds, climate change may become a pressing issue for the herbal community, affecting medicinal plant supply chains with varying requirements for plant cultivation, resource management in the wild, harvesting, processing, and importantly marketing.

Climate And Changing Winter Distribution Of Alcids In The Northwest Atlantic, Richard R. Veit, Lisa L. Manne

Publications and Research

Population level impacts upon seabirds from changing climate are increasingly evident, and include effects on phenology, migration, dispersal, annual survivorship, and reproduction. Most population data on seabirds derive from nesting colonies; documented climate impacts on winter ecology are scarce. We studied interannual variability in winter abundance of six species of alcids (Charadriiformes, Alcidae) from a 58-year time series of data collected in Massachusetts 1954–2011. We used counts of birds taken during fall and winter from coastal vantage points. Counts were made by amateur birders, but coverage was consistent in timing and location. We found significant association between winter abundance of …

Migration Plasticity As An Adaptation To Climate Change: The Spatial Distribution And Abundance Of A Subset Of Neotropical Migrant Landbirds Wintering In The Northeastern United States, Juliette Goulet

Dissertations, Theses, and Capstone Projects

There is a need for accurate predictions of the effects of climate change on wildlife populations. Bioclimatic relationships however are potentially complicated by various environmental factors operating at multiple spatial and temporal scales. Therefore, in order to test the hypothesis that climate constraints of winter bird distributions are modified by species-specific responses to weather and climate, I relied on Christmas Bird Count data (CBC). With nearly 100 years of data, the CBC is a valuable source of information on historic and recent changes in the status and distribution of birds during the early winter period in the United States and …

How Important Is Land-Based Foraging To Polar Bears (Ursus Maritimus) During The Ice-Free Season In Western Hudson Bay? An Examination Of Dietary Shifts, Compositional Patterns, Behavioral Observations And Energetic Contributions, Linda J. Gormezano

Dissertations, Theses, and Capstone Projects

Trophic mismatches between predators and their prey are increasing as climate change causes decoupling of phenological relationships. Predators linked to the life histories of a particular prey will have a more difficult time persisting through environmental change unless they can alter their behavior to maintain the historical match or possess the ability to pursue alternate prey. Arctic predators typically possess flexible foraging strategies to survive in the labile environment, however, quantifying the limits of those strategies can be difficult when life history information is incomplete. In such cases, piecing together different aspects of a predator's foraging behavior, particularly when environmental …

What To Eat Now? Shifts In Polar Bear Diet During The Ice-Free Season In Western Hudson Bay, Linda J. Gormezano, Robert F. Rockwell

Publications and Research

Under current climate trends, spring ice breakup in Hudson Bay is advancing rapidly, leaving polar bears (Ursus maritimus) less time to hunt seals during the spring when they accumulate the majority of their annual fat reserves. For this reason, foods that polar bears consume during the ice-free season may become increasingly important in alleviating nutritional stress from lost seal hunting opportunities. Defining how the terrestrial diet might have changed since the onset of rapid climate change is an important step in understanding how polar bears may be reacting to climate change. We characterized the current terrestrial diet of polar bears …

Genetic Signatures Of A Demographic Collapse In A Large-Bodied Forest Dwelling Primate (Mandrillus Leucophaeus), Nelson Ting, Christos Astaras, Gail Hearn, Shaya Honarvar, Joel Corush, Andrew S. Burrell, Naomi Phillips, Bethan J. Morgan, Elizabeth L. Gadsby, Ryan L. Raaum, Christian Roos

Publications and Research

It is difficult to predict how current climate change will affect wildlife species adapted to a tropical rainforest environment. Understanding how population dynamics fluctuated in such species throughout periods of past climatic change can provide insight into this issue. The drill (Mandrillus leucophaeus) is a large-bodied rainforest adapted mammal found in West Central Africa. In the middle of this endangered monkey’s geographic range is Lake Barombi Mbo, which has a well-documented palynological record of environmental change that dates to the Late Pleistocene. We used a Bayesian coalescent-based framework to analyze 2,076 base pairs of mitochondrial DNA across wild drill populations …
