Thermal Acclimation Of Tropical Coral Reef Fishes To Global Heat Waves, Jacob L. Johansen, Lauren E. Nadler, Adam Habary, Alyssa J. Bowden, Jodie Rummer

Marine & Environmental Sciences Faculty Articles

As climate-driven heat waves become more frequent and intense, there is increasing urgency to understand how thermally sensitive species are responding. Acute heating events lasting days to months may elicit acclimation responses to improve performance and survival. However, the coordination of acclimation responses remains largely unknown for most stenothermal species. We documented the chronology of 18 metabolic and cardiorespiratory changes that occur in the gills, blood, spleen, and muscles when tropical coral reef fishes are thermally stressed (+3.0°C above ambient). Using representative coral reef fishes (Caesio cuning and Cheilodipterus quinquelineatus) separated by >100 million years of evolution and …

Introduction.

Concussions are of significant concern for athletic trainers, and there is a critical need to objectively and safely allow an athlete to return to play. In sports the objective is return as safely and soon as possible. Exertion is a consideration regarding progressing an athlete back to play. The ability to exert in cardiovascular and strength and conditioning contexts are two critical steps in most return to play protocols. Being able to make objective recommendations is urgently needed, as trial and error leads to unnecessary risk of eliciting symptoms and/or causing setbacks.

Evaluating The Use Of Marine Protected Areas By Endangered Species: A Habitat Selection Approach, Kelsey E. Roberts, Brian J. Smith, Derek Burkholder, Kristen M. Hart

Marine & Environmental Sciences Faculty Articles

1. Optimizing the design of marine protected area (MPA) networks for the conservation of migratory marine species and their habitats involves a suite of important considerations, such as appropriate scale requirements and the distribution of anthropogenic impacts. Often, a fundamental component of the conservation planning process is delineating areas of high use or high biodiversity within a region of interest.

2. However, basing conservation strategies off merely the number of individuals in an ecosystem is outdated and potentially subject to arbitrary thresholds. To be effective at protecting marine megafauna, MPAs would ideally encompass habitats used by focal species. Through satellite-tracking …

Late Afternoon Seasonal Transition To Dissolution In A Coral Reef: An Early Warning Of A Net Dissolving Ecosystem?, Laura Stoltenberg, Kai G. Schulz, Coulson A. Lantz, Tyler Cyronak, Bradley D. Eyre

Marine & Environmental Sciences Faculty Articles

There are concerns that reefs will transition from net calcifying to net dissolving in the near future due to decreasing calcification and increasing dissolution rates. Here we present in situ rates of net ecosystem calcification (NEC) and net ecosystem production (NEP) on a coral reef flat using a slack-water approach. Up until dusk, the reef was net calcifying in most months but shifted to net dissolution in austral summer, coinciding with high respiration rates and a lower aragonite saturation state (Ω_arag). The estimated sediment contribution to NEC ranged from 8 – 21 % during the day and 45 …

Analysis Of Global Human Gut Metagenomes Shows That Metabolic Resilience Potential For Short-Chain Fatty Acid Production Is Strongly Influenced By Lifestyle, David K. Jacobson, Tanvi P. Honap, Andrew T. Ozga, Nicolas Meda, Thérèse S. Kagoné, Hélène Carabin, Paul Spicer, Raul Y. Tito, Alexandra J.

High taxonomic diversity in non-industrial human gut microbiomes is often interpreted as beneficial; however, it is unclear if taxonomic diversity engenders ecological resilience (i.e. community stability and metabolic continuity). We estimate resilience through genus and species-level richness, phylogenetic diversity, and evenness in short-chain fatty acid (SCFA) production among a global gut metagenome panel of 12 populations (n = 451) representing industrial and non-industrial lifestyles, including novel metagenomic data from Burkina Faso (n = 90). We observe significantly higher genus-level resilience in non-industrial populations, while SCFA production in industrial populations is driven by a few phylogenetically closely related species (belonging to …

Biology Faculty Articles

Background: Recent studies have identified susceptibility genes of HBV clearance, chronic hepatitis B, liver cirrhosis, hepatocellular carcinoma, and showed the host genetic factors play an important role in these HBV-related outcomes.

Results: In order to discover new susceptibility genes for HBV-related outcomes, we conducted a genome-wide association study in 1031 Chinese participants, including 275 HBV clearance subjects, 92 asymptomatic persistence infection carriers (ASPI), 93 chronic hepatitis B patients (CHB), 188 HBV-related decompensated cirrhosis patients (DC), 214 HBV-related hepatocellular carcinoma patients (HCC) and 169 healthy controls (HC). In the case-control study, we observed novel locus significantly associated with CHB …

Species Sensitivity Assessment Of Five Atlantic Scleractinian Coral Species To 1-Methylnaphthalene, Dorothy-Ellen A. Renegar, Nicholas Turner

Marine & Environmental Sciences Faculty Articles

Coral reefs are keystone coastal ecosystems that are at risk of exposure to petroleum from a range of sources, and are one of the highest valued natural resources for protection in Net Environmental Benefit Analysis (NEBA) in oil spill response. Previous research evaluating dissolved hydrocarbon impacts to corals reflected no clear characterization of sensitivity, representing an important knowledge gap in oil spill preparedness related to the potential impact of oil spills to the coral animal and its photosymbiont zooxanthellae. This research addresses this gap, using a standardized toxicity protocol to evaluate effects of a dissolved reference hydrocarbon on scleractinian corals. …

Autonomous In Situ Calibration Of Ion‐Sensitive Field Effect Transistor Ph Sensors, Philip J. Bresnahan, Yuichiro Takeshita, Taylor Wirth, Todd R. Martz, Tyler Cyronak, Rebecca Albright, Kennedy Wolfe, Joseph K. Warren, Keaton Mertz

Marine & Environmental Sciences Faculty Articles

Ion‐sensitive field effect transistor‐based pH sensors have been shown to perform well in high frequency and long‐term ocean sampling regimes. The Honeywell Durafet is widely used due to its stability, fast response, and characterization over a large range of oceanic conditions. However, potentiometric pH monitoring is inherently complicated by the fact that the sensors require careful calibration. Offsets in calibration coefficients have been observed when comparing laboratory to field‐based calibrations and prior work has led to the recommendation that an in situ calibration be performed based on comparison to discrete samples. Here, we describe our work toward a self‐calibration apparatus …

Three species commonly found in south Florida that are lik ely exposed to MCA by effluent sites or aquaculture facilities are mosquitofish Gambusia affinis pink shrimp Farfantepenaeus duorarum and the hard clam Mercenaria mercenaria These …

Ontogenetic Variation In Sciaenid Otolith Morphometry With Fish Size From The Northern Gulf Of Mexico, Thomas C. Ingalls

All HCAS Student Capstones, Theses, and Dissertations

Sciaenids are a diverse family of coastal fishes and their fisheries are an important industry in the United States. In the northern Gulf of Mexico this industry is dominated by six species, specifically, red drum (Sciaenops ocellatus), black drum (Pogonias cromis), spotted seatrout (Cynoscion nebulosus), sand seatrout (C. arenarius), Atlantic croaker (Micropogonias undulatus), and spot (Leiostomus xathurus). Sagittal otoliths of all species were evaluated for changes in size and shape in relation to changes in fish total length and age across a variety of seasons and habitats. Evaluation …

A Predator-Based Methodology For Studying Predator-Prey Relationships In Fishes, Ashley Vettese

All HCAS Student Capstones, Theses, and Dissertations

Changes in the ocean including acidification, increasing temperatures, loss of habitat, and increased hypoxic events has the potential to change predator-prey relationships. These changes in single interactions can then have effects on population sizes, community structures, and changes in trophic cascades. Understanding how changing abiotic factors impact predator-prey relationships will be crucial for understanding what populations and communities will look like under future ocean conditions. In this review, the goals are to (1) summarize the current knowledge on how changing ocean conditions affect predator-prey relationships; (2) describe an example predator-based approach to examine how changing these changing factors impact predator-prey …

The Role Of Neuropilin-1 In Covid-19, Bindu Mayi, Jillian A. Leibowitz, Arden T. Woods, Katherine A. Ammon, Alphonse E. Liu, Aarti Raja

Biology Faculty Articles

Neuropilin-1 (NRP-1), a member of a family of signaling proteins, was shown to serve as an entry factor and potentiate SARS Coronavirus 2 (SARS-CoV-2) infectivity in vitro. This cell surface receptor with its disseminated expression is important in angiogenesis, tumor progression, viral entry, axonal guidance, and immune function. NRP-1 is implicated in several aspects of a SARS-CoV-2 infection including possible spread through the olfactory bulb and into the central nervous system and increased NRP-1 RNA expression in lungs of severe Coronavirus Disease 2019 (COVID-19). Up-regulation of NRP-1 protein in diabetic kidney cells hint at its importance in a population at …

Social Familiarity Improves Fast-Start Escape Performance In Schooling Fish, Lauren E. Nadler, Mark I. Mccormick, Jacob L. Johansen, Paolo Domenici

Marine & Environmental Sciences Faculty Datasets

Using social groups (i.e. schools) of the tropical damselfish Chromis viridis, we tested how familiarity through repeated social interactions influences fast-start responses, the primary defensive behaviour in a range of taxa, including fish, sharks, and larval amphibians. We focused on reactivity through response latency and kinematic performance (i.e. agility and propulsion) following a simulated predator attack, while distinguishing between first and subsequent responders (direct response to stimulation versus response triggered by integrated direct and social stimulation, respectively). In familiar schools, first and subsequent responders exhibited shorter latency than unfamiliar individuals, demonstrating that familiarity increases reactivity to direct and, potentially, …

Caribbean Fad Tracking Project Dataset, Erin E. Kimak, David W. Kerstetter, Thomas D. Pitchford

Kerstetter Fisheries and Avian Ecology Lab Datasets

This dataset encompasses crowd-sourced reports of abandoned, lost or otherwise discarded fishing gear (ALDFG), particularly drifting Fish Aggregating Devices (dFADs) from citizen scientists around the North Atlantic Ocean and greater Caribbean region. Data collection did not involve survey efforts, but rather keyword searches of affiliated terms such as "bamboo raft" and "satellite buoy", as well as collection of reports via email and Facebook. Although this dataset is incomplete and an under representation of the total number of ALDFG dFADs as a result of widespread nature of stranding locations, it provides a minimum estimate of the numbers of FADs stranding in …

Unexpected Role Of Communities Colonizing Dead Coral Substrate In The Calcification Of Coral Reefs, Manoela Romanó De Orte, David A. Koweek, Tyler Cyronak, Yuichiro Takeshita, Alyssa Griffin, Kennedy Wolfe, Alina Szmant, Robert Whitehead, Rebecca Albright, Ken Caldeira

Marine & Environmental Sciences Faculty Articles

Global and local anthropogenic stressors such as climate change, acidification, overfishing, and pollution are expected to shift the benthic community composition of coral reefs from dominance by calcifying organisms to dominance by non-calcifying algae. These changes could reduce the ability of coral reef ecosystems to maintain positive net calcium carbonate accretion. However, relationships between community composition and calcification rates remain unclear. We performed field experiments to quantify the metabolic rates of the two most dominant coral reef substrate types, live coral and dead coral substrate colonized by a mixed algal assemblage, using a novel underwater respirometer. Our results revealed that …

Addressing Health-Related Myths In The Culturally Diverse African American Population: A Call To Action, Lucson Joseph

Internet Journal of Allied Health Sciences and Practice

African Americans (AAs) experience numerous challenges that socially, economically, and physically affect their communities. Recent studies have found that a diverse array AAs encounter many struggles as they navigate the United States (U.S.) healthcare system to access care and receive healthcare services. AA communities are significantly affected by the burden of chronic diseases. They face considerable barriers to healthcare services that contribute to adverse health outcomes. This paper explains the daily struggles many AAs face within their communities to access and navigate the healthcare system due to culturally held myths and barriers. This paper discusses commonly held myths among Afro-Caribbean …
