Alfred Russel Wallace Notes 18: Wallace On The Balance Of Nature, Charles H. Smith Aug 2021

Alfred Russel Wallace Notes 18: Wallace On The Balance Of Nature, Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) had a unique perspective on the ‘balance of nature’: he avoided classical thoughts on the subject, but nevertheless seems to have adopted elements of the ‘balance’ concept while acknowledging that irreversible change occurs at both the biological and environmental levels. Wallace’s position can be understood from his grounding in Humboldtian ‘equilibrium of forces’ thinking, and his turn toward ‘final causes’-based interpretations.

Diversity And Host Specificity Of Nycteribiid Bat Flies (Diptera: Nycteribiidae) In Kenya, Taylor Verrett Jul 2021

Diversity And Host Specificity Of Nycteribiid Bat Flies (Diptera: Nycteribiidae) In Kenya, Taylor Verrett

Masters Theses & Specialist Projects

Bat flies (Diptera: Nycteribiidae and Streblidae) are hematophagous ectoparasites of bats distributed globally. Members of Nycteribiidae are morphologically constrained relative to streblids, and are united by their lack of wings, dorso-ventrally compressed bodies, and a primary distribution across the Eastern hemisphere. Bats are principal reservoirs of infectious diseases, including viral zoonoses of important consideration to human health, but the overall high host specificity of bat flies has largely been thought to curb their potential as inter-specific vectors of bat-borne pathogens. However, nycteribiid diversity and host associations remain critically understudied in some geographic regions, and rare examples of nycteribiid bat flies …

The Effect Of Freeze-Thaw Events On Dna Integrity In The Gray Treefrog (Hyla Versicolor), Georgia Ficarra Jul 2021

The Effect Of Freeze-Thaw Events On Dna Integrity In The Gray Treefrog (Hyla Versicolor), Georgia Ficarra

Masters Theses & Specialist Projects

Freeze-tolerant gray treefrogs survive winter by producing natural cryoprotectants and accommodating ice formation within extracellular spaces. While frozen, gray treefrogs endure hyperglycemia, dehydration, and anoxia due to the halt of all bodily functions. Upon thawing, the frogs’ anoxic cells receive a rapid influx of oxygen, which can cause oxidative damage to vital macromolecules including DNA. Previous studies have suggested freeze-tolerant frogs avoid oxidative damage after freeze-thaw events by elevating antioxidant activity, but recent work has shown upregulated DNA repair encoding genes in post-freeze frogs. The objective of this thesis is to assess the cellular costs of freezing by measuring oxidative …

Cellular Toxicity Of Malonato (Ethylenediamine) Platinum (Ii) In Models Of Cancer, Sidikat Olanrewaju Olajuwon Jul 2021

Cellular Toxicity Of Malonato (Ethylenediamine) Platinum (Ii) In Models Of Cancer, Sidikat Olanrewaju Olajuwon

Masters Theses & Specialist Projects

Platinum(II) compounds including the three FDA approved drugs, cisplatin, carboplatin, and oxaliplatin, are composed of two structural components, a leaving ligand, and a non-leaving ligand, each attached to a central platinum(II) atom. All bifunctional platinum compounds studied have similar mechanisms of initiating cell death. However, their efficacy as chemotherapeutics depends on the tissues in which the cancer originates. No model has explained these tissue-specific efficacies. We hypothesized that the efficacies of these platinum compounds vary due to structural differences in the leaving ligands. To test the influence of the leaving ligand on cellular survival, novel platinum compounds were synthesized, and …
