The University of New England received a $178,575 Project Grant from the National Science Foundation's Division of Polar Programs (CFDA 47.078) effective July 1, 2025 through June 30, 2027. This collaborative research project investigates the microbiome composition and functional roles of gut-associated microorganisms, specifically mollicutes and other bacteria, inhabiting the Antarctic pteropod Limacina rangii. The research employs modern genetic tools including deoxyribonucleic acid (DNA) sequencing and metagenomics analysis to characterize microbial diversity and function, utilizing samples collected over the past decade in partnership with international researchers. The study examines how these microbial communities vary across time and space in the western Antarctic Peninsula and Ross Sea regions, and how they may enable pteropods to adapt to changing ocean conditions.
Beyond the primary scientific objectives, the award supports workforce development through training of graduate and undergraduate students and advancement of early-career researchers. The project includes educational outreach components designed to engage the public through hands-on educational events and classroom materials. By examining the host-microbe relationship in a rapidly warming and vulnerable Antarctic ecosystem, this research contributes to broader understanding of climate impacts on Southern Ocean food web dynamics and supports national efforts to sustain ocean health and biodiversity.
