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...

Shifts in Microbial Communities Based Upon Transect Habitat

Creator:: Greydanus, Logan
Abstract:: Coral reef health has been in severe decline around the globe in the past several decades, in many cases due to direct human impact. Human action, such as overfishing, habitat destruction and nutrient loading, has caused coral coverage to drop to record lows, threatening the future of these critically important...

Using 16S rRNA Gene Amplicon Sequencing and quantitative PCR (qPCR) to Evaluate Microbial Community and Pathogen Dynamics in Acropora cervicornis Corals

Creator:: Patel, Shalvi H.
Abstract:: Coral reefs are diverse ecosystems and serve many purposes including preventing erosion on coastlines and acting as a source of food, income, and culture. Acropora cervicornis, a staghorn coral, has faced a significant 80-89% decline in the Caribbean, attributed to a poorly-characterized epizootic, White Band Disease (WBD). Previous studies showed...

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...

What is killing the corals? Viral and bacterial interrogations using metagenomics and microscopy

Creator:: Soffer, Nitzan
Abstract:: Corals have multiple roles in maintaining ocean health and are some of the world’s most diverse ecosystems. The coral animal is host to a multitude of taxa, including symbiotic dinoflagellate algae, fungi, bacteria, protists, and viruses. Environmental stressors and disease agents can perturb the delicate balance of the coral host...

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,...

Supplemental Description of Myxobolus squamalis (Myxozoa) & Epidemiology of M. squamalis at Two Oregon Hatcheries

Creator:: Polley, Tamsen M.
Abstract:: Myxobolus squamalis is a Myxozoan parasite of salmonids, which contributes to lowered fitness of hatchery and wild fish in the Pacific Northwest of North America. The only GenBank DNA sequence of M. squamalis is from Oncorhynchus tschawytscha (Chinook), but is not linked to a published morphological description. There is a...

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...
