Background: Zostera marina is an important ecosystem engineer influencing shallow water environments and possibly shaping the microbiota in surrounding sediments and water. Z. marina is typically found in marine systems, but it can also proliferate under brackish conditions.

Article Synopsis
  • Telonemia are ancient marine protists with established evolutionary links to the SAR supergroup, but their ecological roles and distribution in freshwater environments remain under-researched.
  • A global study of over a thousand freshwater metagenomes and 407 samples from lakes revealed a wide distribution of Telonemia, though no new major clades were identified, indicating their diversity is well-represented in current surveys.
  • Findings suggest Telonemia prefer colder, deeper areas of lakes in the Northern Hemisphere, where they can make up 10%-20% of the heterotrophic flagellate population, highlighting their significance in freshwater food webs.

Article Synopsis
  • * Data collected from health agencies and scientific literature shows a sharp increase in reported infections (1,553 cases), with a notable correlation between rising sea surface temperatures and infection rates in Sweden and Germany.
  • * The findings highlight the lack of consistent surveillance across BSR countries, suggesting the need for enhanced monitoring programs to better protect public health, especially with climate change affecting infection dynamics.

The factors that influence the distribution of bacterial community composition are not well understood. The role of geographical patterns, which suggest limited dispersal, is still a topic of debate. Bacteria associated with hosts face unique dispersal challenges as they often rely on their hosts, which provide specific environments for their symbionts.
