Characterizing the Accuracy of Phylogenetic Analyses that Leverage 16S rRNA Sequencing Data

Creator:: Humphreys, Ian R.
Abstract:: Investigations of 16S rRNA gene sequences hallmark modern microbiology. These sequences provide culture-independent insight into the abundance and distribution of microbiota and serve as a principle resource through which microbial community diversity is measured. Consequently, researchers rely on 16S gene sequences to test hypotheses rooted in ecology, evolution, and disease....

Multiple Stressors Drive Changes in Coral Microbiome Diversity and Composition Demonstrating the Role of a Bacterial Symbiont in Microbial Community Sensitivity and Resilience

Creator:: Maher, Rebecca L.
Abstract:: On coral reefs, disturbances rarely occur in isolation. Global stressors such as increasing seawater temperature often coincide with local stressors like nutrient pollution. In the face of increasing anthropogenic stress, corals can function as environmental sentinels, although little is known about how multiple stressors interact to disrupt their associated bacterial...

Impacts of Environmental Change on a Newly-characterized Symbiosis between a Novel Bacterial Parasite, Genus Aquarickettsia, and the Coral Acropora cervicornis

Creator:: Klinges, J. Grace
Abstract:: Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...

Ecophylogenetic Characterization of the Gut Microbiome of At-risk Companion and Food Animals

Creator:: Kirchoff, Nicole S.
Abstract:: Agricultural and companion animals are integral to our way of life as they provide us with nourishment, financial resources, transportation, and companionship. However, pets, managed animals in the agricultural industry, as well as wild populations of food animals are all subject to health and mortality risks. The gut microbiome is...

Species- and Temporal-Specific Coral Microbiome Fluctuations in Response to a Natural Bleaching Event

Creator:: Ewton, Erica M.
Abstract:: Corals provide a diversity of ecosystem services, are among the most biologically diverse ecosystems on Earth, and directly support ~500 million people globally; however, corals are increasingly experiencing significant threats and are undergoing severe bleaching events as the result of the warming climate. Using a two-year data set surrounding a...

Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

Creator:: Wang, Lu
Abstract:: Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

Unprecedented evidence for high viral abundance and lytic activity in coral reef waters of the South Pacific Ocean

Creator:: Payet, Jérôme P., McMinds, Ryan, Burkepile, Deron E., and Thurber, Rebecca L. Vega
Abstract:: Despite nutrient-depleted conditions, coral reef waters harbor abundant and diverse microbes; as major agents of microbial mortality, viruses are likely to influence microbial processes in these ecosystems. However, little is known about marine viruses in these rapidly changing ecosystems. Herewe examined spatial and short-term temporal variability in marine viral abundance...

Bacterial Predation in Host Microbiomes

Creator:: Welsh, Rory M.
Abstract:: In host-associated microbiomes, the mechanisms that regulate community composition or the principles that govern dynamics remain far from clear. However, understanding how the structure of microbial communities shift as the system moves away from a healthy state is critical to assessing disease progression and to formulate any potential mitigation strategy....

The Evolution of Scleractinian Microbial Symbionts

Creator:: McMinds, Ryan C.
Abstract:: The modern world has presented many threats to the health and stability of ecosystems worldwide. One of the most biodiverse ecosystems, coral reefs, faces particularly strong pressures, and is already declining rapidly in complexity and area. Although the stressors that affect reefs are diverse, ranging from nutrient pollution to overfishing,...

Reef Microbiomes of Mo'orea, French Polynesia, a Socio-Ecological Island System

Creator:: McConnell, Kaitlin M.
Abstract:: At a time of rapid global change, a socio-ecological system (SES) approach can provide a framework through which to quantify and communicate the risks and uncertainties of coupled human-natural systems. Islands, and tropical coral reef islands in particular, can be excellent models for SES research since they may be considered...
