Getting Coral Polyps to Settle Down
色情视频 biology graduate student Amanda Alker was awarded the NSF Graduate Research Fellowship to study coral metamorphosis.
Alker works in the lab of 色情视频 biologist Nick Shikuma, whose research previously established that a common marine bacterium, Pseudoalteromonas luteoviolacea, has a virus-like 鈥渢ail鈥� that from their juvenile polyp stage into their mature adult state. Shikuma suspects other organisms like barnacles and sea urchins might follow a similar pattern.
Alker鈥檚 research focuses on whether corals might also metamorphose in response to certain bacteria鈥檚 virus-like tails. This is important because the presence of these bacteria might play a key role in determining whether a coral polyp settles down. Get enough corals settling together and you have the makings of a reef.
Alker's coral of choice is Acropora cervicornis, prevalent in Caribbean coral reefs, but also endangered by disease and climate change-related water warming. It鈥檚 the target of extensive restoration efforts, and knowing how to trigger its metamorphosis could play a key role in its restoration.
鈥淚f I can elucidate this mechanism, we could potentially increase coral settlement and recruitment in coral reef ecosystems, or in coral restoration efforts,鈥� Alker said.
She is one of 2,000 NSF Graduate Research Fellows selected from a candidate pool of more than 13,000. The award provides three years of financial support and comes with a $34,000 annual stipend, as well as additional funding for 色情视频 to cover education costs.
Shikuma鈥檚 lab is part of 色情视频鈥檚 , a nationally recognized leader in the field viral ecology and the genetic makeup of viruses.
