The study was published in the journal Scientific Reports. Certain diseases in corals are either endemic, meaning they are consistently found at baseline levels in the environment, or epidemic, meaning there are periods with big outbreaks or then they seem to disappear. Though important to understand, it has been a challenge for researchers to study how those diseases are transmitted because of low rates of occurrence.

Studies of the health hazards of toxic algae blooms have focused largely on the danger of direct contact with contaminated water in lakes, rivers and the ocean. Now a new study shows that even airborne exposure to the bacteria from a toxic bloom could also pose a risk.
That hurricanes can create sudden and dramatic changes to the landscape is obvious to anyone who lives along the Gulf of Mexico's coast. They are powerful, high-energy destructive forces that can flood homes and fell trees, and can leave a lasting impression on all those affected by them; however, the mark hurricanes leave on unpopulated areas, such as Florida's Everglades National Park, have been less known until now. In a recent paper published in the Proceedings of the National Academy of Sciences, or PNAS, researchers from different universities, including LSU, examined how Hurricanes Wilma in 2015 and Irma in 2017 fertilized the Florida Coastal Everglades, paradoxically facilitating mangrove wetlands recovery.
Scientists studying sperm whales have discovered earthquakes affect their ability to find food for at least a year. The research is among the first to examine the impact of a large earthquake on a population of marine mammals, and offers new insight into how top predators such as sperm whales react and adapt to a large-scale natural disturbance.

Florida has experienced numerous harmful algal blooms in recent years, including blue-green algae and their toxins in 2016 and 2018. Despite their intensity and frequency, there is scant data on human exposure to these blooms and concentrations of the toxins they produce in tissues of exposed individuals. The most common routes of human exposure to these toxins include direct contact, ingestion and inhalation. Little is known about airborne exposure to these toxins in recreationally and occupationally exposed humans.
Marine biologists are flying a bespoke mini-submarine under the sea ice to explore environments around Davis research station that have never been seen before.
Coralline red algae (CRA) are important ecosystem engineers in the world’s oceans. They play key roles as primary food source and carbonate producers in marine habitats. CRA are also vital for modern reef systems where they act as substrate for coral growth and stabilizers of reef frameworks. However, morphotaxonomic identification of these important marine organisms is hampered by the fact that morphological concepts used for their classification do not correspond to molecular data. We present the first analysis of nanoscale features in calcified cell walls of CRA in a globally distributed sample set. We use new morphological traits based on these cell wall ultrastructures to construct an independent morphological phyletic tree that shows a promising congruency with existing CRA molecular phylogenies. Our results highlight cellular ultrastructures as a tool to define the phenotypic expression of genotypic information showing their potential to unify morphology with molecular phylogeny.
Oceans and coastal plant species such as mangroves and seagrasses cover only a small fraction of the earth, but are responsible for sequestering over half of all the carbon captured by living organisms. However, despite being some of the most efficient known carbon sinks, they are also among the ecosystems most threatened by climate change. Threats such as rising sea levels and temperatures, offshore drilling, erosion and pollution have resulted in the rapid deterioration of coastal and marine areas.
Major oil spills are catastrophic events that immensely affect the environment and society, yet determining their spatial extent is a highly complex task. During the Deepwater Horizon (DWH) blowout, ~149,000 km2 of the Gulf of Mexico (GoM) was covered by oil slicks and vast areas of the Gulf were closed for fishing. Yet, the satellite footprint does not necessarily capture the entire oil spill extent. Here, we use in situ observations and oil spill transport modeling to examine the full extent of the DWH spill, focusing on toxic-to-biota (i.e., marine organisms) oil concentration ranges. We demonstrate that large areas of the GoM were exposed to invisible and toxic oil that extended beyond the boundaries of the satellite footprint and the fishery closures. With a global increase in petroleum production–related activities, a careful assessment of oil spills’ full extent is necessary to maximize environmental and public safety.
