Images: Journey Into the Ocean's Microbiomes

MIT-WHOI Joint Program graduate student Amalia Aruda Almada explored symbiotic relationships between ubiquitous shrimplike organisms in the ocean called copepods and bacteria that hitchhike on them. Sometimes the bacteria, like the ones that cause cholera, can be pathogenic. (Ann Tarrant, Woods Hole Oceanographic Institution)
Like many graduate students, Amalia Aruda Almada was inspired by mentors. One of hers was University of Maryland microbiologist Rita Colwell, who discovered a relatively easy way to dramatically reduce the spread of cholera in Bangladesh. (John T. Consoli)
Graduate student Amalia Aruda Almada's other mentor was her Ph.D. advisor at WHOI, biologist Ann Tarrant. (Courtesty of Ann Tarrant, Woods Hole Oceanographic Institutioin)
Copepods are small marine crustaceans that eat phytoplankton and are an important link in the ocean food chain. (Ken Kostel, Woods Hole Oceaongraphic Institution)
Bacteria often attach themselves to copepods, and graduate student Amalia Aruda Almada explored whether copepods received any benefits from the relationship or whether they were just passive rafts. She also explored whether copepods could actively attract or avoid particular types of bacteria from attaching and whether the copepods in some ways affect the lifestyles of bacteria.
