Coral reefs face serious threats primarily arising from climate change, unsustainable fishing, and pollution. To better understand the underlying processes, a multidisciplinary series of studies is being conducted by researchers, investigating variability in coral reef community structure and microbial dynamics across gradients of natural and anthropogenic stress. Their results are published in the new PeerJ "Line Islands Collection – Microbial dynamics of coral reef robustness and decline" (named after their upcoming expedition to the Line Islands).
As part of an effort to better understand the effects of anthropogenic influences on these fascinating ecosystems, and specifically how microbial communities affect coral reef robustness and decline, a new expedition to the Line Islands (located in the central Pacific Ocean and one of the most pristine coral reef systems remaining on the planet) will be launched in the fall of 2013. In the run-up to this expedition, a Collection of related articles is being launched in the open access journal PeerJ and as the work of this research collaboration builds up, the Collection will continually expand to include all relevant publications.
The main focus of the Line Islands expedition will be to shed light on the intricate interactions between microbes, coral, algae, and fish and so the researchers leading this body of work have expertise spanning many different scientific disciplines:
The Laboratory of Forest Rohwer, of San Diego State University, investigates the interactions between microbes and macroorganisms in coral reefs, specifically how these systems respond to perturbation. Jennifer E. Smith and her team from Scripps will…
