In vitro Symbiosis of Reef-Building Coral Cells With Photosynthetic Dinoflagellates

Frontiers in Marine Science, 2021
Coral reefs are the biodiversity hot spots of the oceans, but they have suffered from increasing environmental stresses caused principally by anthropogenic global warming.

Baseline Assessment of Ecological Quality Index (EQI) of the Marine Coastal Habitats of Tonga Archipelago: Application for Management of Remote Regions in the Pacific

Remote Sensing, 2023
The loss of coral habitats and associated biodiversity have direct effects both on the physical dynamics of the coast and on natural resources, threatening the survival of local populations.

Discovery and characterization of Hv1-type proton channels in reef-building corals

eLife, 2021
Voltage-dependent proton-permeable channels are membrane proteins mediating a number of important physiological functions. Here we report the presence of a gene encoding Hv1 voltage-dependent, proton-permeable channels in two species of reef-building ...

High-Resolution Dynamics of Hydrogen Peroxide on the Surface of Scleractinian Corals in Relation to Photosynthesis and Feeding

Frontiers in Marine Science, 2022
We developed and used a microsensor to measure fast (<1 s) dynamics of hydrogen peroxide (H2O2) on the polyp tissue of two scleractinian coral species (Stylophora pistillata and Pocillopora damicornis) under manipulations of illumination ...

Reactive Oxygen Species Signaling Pathways: Arbiters of Evolutionary Conflict?

Oxygen, 2022
In the history of life, cooperation between biological units has led to increased complexity, e.g., eukaryotic cells and multicellular organisms. Cooperation requires limiting the gains of “defectors” in favor of the cooperative higher-level unit.

Characterization of Available Light for Seagrass and Patch Reef Productivity in Sugarloaf Key, Lower Florida Keys

Remote Sensing, 2016
Light availability is an important factor driving primary productivity in benthic ecosystems, but in situ and remote sensing measurements of light quality are limited for coral reefs and seagrass beds.

Chemical mutagenesis and thermal selection of coral photosymbionts induce adaptation to heat stress with trait trade‐offs

Evolutionary Applications, 2023
Despite the relevance of heat‐evolved microalgal endosymbionts to coral reef restoration, to date, few Symbiodiniaceae strains have been thermally enhanced via experimental evolution. Here, we investigated whether the thermal tolerance of Symbiodiniaceae

Collagen of Extracellular Matrix from Marine Invertebrates and Its Medical Applications

Marine Drugs, 2019
The extraction and purification of collagen are of great interest due to its biological function and medicinal applications. Although marine invertebrates are abundant in the animal kingdom, our knowledge of their extracellular matrix (ECM), which mainly
