Dr. Maggie Johnson, a recent Smith Lab PhD grad, recently published a study in the journal Coral Reefs revealing how epilithic and endolithic algae (that is, algae that grows on top of and beneath the surface of “rocks”, respectively) respond to increasing ocean temperature and acidification (lower pH). Samples were collected from turf-covered substrate in Moorea, and were exposed for … Read More
A new paper published by Emily Kelly and colleagues explains how we can balance the energetic budget on Hawaiian coral reefs through herbivore management and protection. Herbivores on coral reefs play an important role in controlling algal growth, but in systems where density of herbivores is low, algae can grow at a faster rate than they are consumed, resulting in a … Read More
The 100 Island Challenge is a collaborative project led by Dr. Stuart Sandin’s lab, co-led by Dr. Jen Smith, that aims to work with partners worldwide to assess reef health in a holistic way that is comparable across all sites. News Deeply recently interviewed Dr. Smith to learn more about the goals of the 100 Island Challenge in assessing reef … Read More
Crown-of-Thorns Starfish Larvae can feed on Organic Matter Released from Corals Ryota Nakajima, Nobuyuki Nakatomi, Haruko Kurihara, Michael D. Fox, Jennifer E. Smith, and Ken Okaji Abstract: Previous studies have suggested that Crown-of-Thorns starfish (COTS) larvae may be able to survive in the absence of abundant phytoplankton resources suggesting that they may be able to utilize alternative food sources. Here, … Read More
Coral reefs are home to a large diversity of organisms. The herbivorous fishes, those fish that eat algae in competition with corals, are no exception to such diversity. But do the many species of herbivores have unique grazing roles on reefs or are all herbivorous fishes grazing alike? This was the focus of a study recently published in Oecologia … Read More
Assessment of net community production and calcification of a coral reef using a boundary layer approach Abstract: Coral reefs are threatened worldwide, and there is a need to develop new approaches to monitor reef health under natural conditions. Because simultaneous measurements of net community production (NCP) and net community calcification (NCC) are used as important indicators of reef health, tools are … Read More
This Saturday, March 15th, Susan Kram will be talking about climate change and ocean acidification at Birch Aquarium’s March Sea Days
Maggie Johnson is a third-year PhD student in the Smith Lab at Scripps Institution of Oceanography. This is a blog she wrote for the Smithsonian Institution’s Ocean Portal describing her recent cruise to the Southern Line Islands, along with other researchers from Scripps Institution of Oceanography, UC San Diego.
