A new thermally tolerant species of algae is found!

Rising ocean temperatures threaten coral reefs, but a new thermal tolerant algae could help. Valeska UphamFor my fisheries and aquatic science PhD I am working on how to tank raise urchins and transplant them onto reefs across the Florida Keys in order to help reverse the phase shift from algae dominated back to coral dominated.

Is a coral’s color all for show?

Two of the exact same corals, sitting right next to each other, often appear to be different based on their colors. Why is this? Scientists have shown that the answer involves intriguing genetics. The more genes a coral activates, the greater their strength of color. Valeska UphamFor my fisheries and aquatic science PhD I am […]

One fish, two fish, red fish… glow fish?

Biofluorescence of coral is well studied, but in this paper, Sparks et al. aimed to investigate the little known details regarding the impact of biofluorescence on the other creatures that thrive in coral reef habitats, specifically the 8,000+ species of fishes. What they found was shocking. Not only is biofluorescence widespread throughout the tree of […]

You Are What Your Fish Eats: how an invasive seaweed is contributing to the decline in nutritional value of commercial fish

Invasive species are known to be harmful to native species, biodiversity, and ecosystem function. But recent research has shown that certain invasive species may be affecting the nutritional quality of your food! Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont McKenna College. I work with Dr. Sarah Gilman, […]

Marine herbivores “steal” and use chemical defenses from algal hosts

A recent study has shown that a species of amphipod is disregarding the “WARNING: DO NOT INGEST” label on chemically defended seaweed. As it turns out, these tiny herbivores are able to sequester (seize and store), via ingestion, some of the toxins found within the tissues of macroalgae. These amphipods then use the sequestered toxins […]

Growing Like a Seaweed: How ocean acidification is aiding the growth and expansion of macroalgae.

While calcifying organisms like corals and bivalves are projected to struggle under future levels of carbon dioxide (CO2), non-calcifying seaweeds that use CO2 for photosynthesis are going to exhibit normal, or increased, growth and productivity. Here, researchers show that increases in CO2 result in faster growth rates and increased photosynthetic activity in the invasive red […]
