Shore-based submersible operations, from 2006 to 2020, have allowed us to examine megabenthic assemblages along the island margin of Isla de Roatán from depths of about 150 to 750 m, including repeated observations of the same organisms. These dives were used to photo-document a diverse benthic assemblage and observe the health and condition of the sessile fauna in a well-explored but relatively undocumented area of the Mesoamerican Reef. Samples were collected by dip net, and some dives profiled the water column chemistry in the year 2011. The deep-sea coral assemblage observed off Roatan exhibits high abundance and diversity. The sessile …


Case Study: Degenerative Joint Disease In Canines, Zachary B. Lawrence, Rusty Rogers, Emily Schmitt Lavin Jan 2022

Case Study: Degenerative Joint Disease In Canines, Zachary B. Lawrence, Rusty Rogers, Emily Schmitt Lavin

Mako: NSU Undergraduate Student Journal

Degenerative joint disease (DJD) is the gradual degeneration of cartilage in joints, resulting in pain for the affected areas. This study focused on Lacy (name changed for privacy), a 10-year-old spayed female chihuahua mix, that was clinically diagnosed for DJD and treated by Dr. Rogers over a period of 15 months. DJD is typically treated through a combination of pharmacological management, nonpharmacological treatment, and changes in lifestyle. Pharmacological treatment utilized pain medications, such as Gabapentin and Tramadol. Nonpharmacological treatment and changes in lifestyle involve methods, such as maintaining an ideal body weight, to decrease pain and increase mobility. However, during …

Evidence-based studies on the benefits of integrating STEM into the arts are limited; however, some suggest that it can lead to improved scientific literacy and new approaches for artistic scholarship. Unfortunately, undergraduate education often creates disciplinary silos where the two are not integrated. Here, we discuss a unique collaboration between professors in the art and biology departments. Our goal was to integrate science into art courses using an agar art activity. We hypothesized that art students could effectively learn microbiology laboratory techniques and use them as novel tools for artistic practice. The activity was integrated into two to four sessions …

Coral reef metabolism underpins ecosystem function and is defined by the processes of photosynthesis, respiration, calcification, and calcium carbonate dissolution. However, the relationships between these physiological processes at the organismal level and their interactions with light remain unclear. We examined metabolic rates across a range of photosynthesising calcifiers in the Caribbean: the scleractinian corals Acropora cervicornis, Orbicella faveolata, Porites astreoides, and Siderastrea siderea, and crustose coralline algae (CCA) under varying natural light conditions. Net photosynthesis and calcification showed a parabolic response to light across all species, with differences among massive corals, branching corals, and CCA that …

Sequencing The Mitochondrial Dna Of Lagenidium Juracyae, Kunal Kanwar Jan 2022

Sequencing The Mitochondrial Dna Of Lagenidium Juracyae, Kunal Kanwar

Honors Theses

Lagenidium oomycetes are fungus-like eukaryotic microorganisms that are closely related to diatoms and brown algae. One defining characteristic of Lagenidium oomycetes is their ability to act as a parasite during the larval stage of mosquitoes. Thus, over the past few decades, mosquito infecting Lagenidium oomycetes have been considered to serve as pesticides in various industries. However, some Lagenidium oomycetes have been linked to new mammalian skin conditions, particularly in dogs. As more research has been conducted about these skin conditions, there has been new data showing the presence of new species of Lagenidium oomycetes aside from the most popular Lagenidium …

Sea-Phages

Antibiotic resistance is a global healthcare concern because it poses a threat to effectively treating bacterial infections and the need for alternative therapeutics are urgently required. Phage therapy, which uses viruses to treat bacterial infections, is a promising alternative to conventional antibiotics. Phages have also been widely used in the food industry to prevent microbial growth on certain foods and are currently being explored as a method for bioremediation of oil spills and wastewater treatment. Although phages are ubiquitous in nature, many have yet to be discovered. Through the SEA-PHAGES (Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science) program …

Plastic pollution is increasingly recognized as a global problem. In particular, plastic pieces <5 mm in size (‘microplastics’) are of interest due to their prevalence and association with harmful, persistent organic pollutants (POPs). Very little is known about the prevalence of microplastics in coastal birds. Yet, these water-associated birds are at a high risk of ingesting microplastics that accumulate near the water’s surface. This study describes the microplastics found in the proventriculus and ventriculus of four species of coastal birds regarding quantity, size, type (fiber or fragment), and color (light, mid, or dark). A total of 643 microplastic particles were identified, with 43 of the 44 study specimens containing microplastics (97.7% frequency). The ‘fiber’ type and the ‘mid’ color were the most common microplastics. There were no significant differences between species for particle sizes, but Brown Pelicans contained significantly more particles than the other three species. These results highlight the prevalence of plastic pollution in medium-sized seabirds, but more work is needed to determine microplastic patterns between taxa and foraging environments.

Stroke is the most common cause of epilepsy and ultimately leads to a decrease in the quality of life of those affected. Ischemic and hemorrhagic strokes can both lead to poststroke epilepsy (PSE). Significant risk factors for PSE include age < 65age less than 65 years, stroke severity measured by the National Institutes of Health Stroke Scale (NIHSS), cortical involvement, and genetic factors such as TRPM6 polymorphism. The diagnosis of PSE is made by using imaging modalities, blood biomarkers, and prognostic criteria. Electroencephalography (EEG) is currently the gold standard to diagnose PSE, while new combinations of modalities are being tested to increase diagnostic specificity. This literature review uncovers a newly found mechanism for the pathology of poststroke epilepsy. The pathogenesis of early-onset and late-onset is characterized by sequelae of neuronal cellular hypoxia and disruption of the blood-brain barrier, respectively. Interleukin-6 is responsible for increasing the activity of glial cells, causing gliosis and hyperexcitability of neurons. Epinephrine, high-mobility group protein B1, downregulation of CD32, and upregulation of HLA-DR impact the pathology of poststroke epilepsy by inhibiting the normal neuronal immune response. Decreased levels of neuropeptide Y, a neurotransmitter, act through multiple unique mechanisms, such as inhibiting intracellular Ca accumulation and acting as an anti-inflammatory, also implemented in the worsening progression of poststroke epilepsy. Additionally, CA1 hippocampal resonant neurons that increase theta oscillation are associated with poststroke epilepsy. Hypertensive small vessel disease may also have an implication in the temporal lobe epilepsy by causing occult microinfarctions. Furthermore, this review highlights the potential use of statins as primary prophylaxis against PSE, with multiple studies demonstrating a reduction in incidence using statins alone, statins in combination with antiepileptic drugs (AEDs), and statins with aspirin. The evidence strongly suggests that the second generation AEDs are a superior treatment method for PSE. Data from numerous studies demonstrate their relative lack of significant drug interactions, increased tolerability, and potential superiority in maintaining seizure-free status.

[Chapter Abstract] 230Coral reefs provide critical ecological and geomorphic (e.g. sediment production for reef-fronted shoreline maintenance) services, which interact in complex and dynamic ways. These services are under threat from climate change, requiring dynamic modelling approaches that predict how reef systems will respond to different future climate scenarios. Carbonate budgets, which estimate net reef calcium carbonate production, provide a comprehensive ‘snap-shot’ assessment of reef accretionary potential and reef stability. These budgets, however, were not intended to account for the full suite of processes that maintain coral reef services or to provide predictive capacity on longer timescales (decadal to centennial). To …
