Lobster embryo microbiomes remain resilient in future ocean conditions, sequencing reveals

Phys · · 805 words · By Virginia Institute

Researchers from William & Mary's Batten School and VIMS found that the microbiomes of American lobster embryos remain stable and diverse despite simulated increases in ocean temperature and acidity. The study suggests these microbial communities may provide resilience against environmental stressors and pathogens in the Gulf of Maine.
