Congratulations Tricia Thibodeau who recently published exciting work in the journal Aquatic Microbial Ecology. The pteropod (pelagic snail) Limacina helicina antarctica is a dominant grazer along the Western Antarctic Peninsula (WAP) and plays an important role in regional food web dynamics and biogeochemical cycling. Tricia for the first time, we examined the gut microbiome and feeding ecology of L. h. antarctica based on 16S and 18S rRNA gene sequences of gut contents in the WAP during austral summer. The gut contents indicated that this species predominantly feeds on diatoms and dinoflagellates, supplementing its diet with ciliates and foraminifera.
