Extremely high abundances of Prasiola crispa-associated micrometazoans in East Antarctica
To elucidate poorly known aspects of the microscopic metazoan distribution in ice-free parts of the Antarctic, we examined samples of the multicellular terrestrial algaPrasiola crispa, collected over the last decade in different parts of continental East Antarctica and Haswell Island. We found that...
