A Kobe University study shows that small aquatic beetles survive catfish attacks by resisting ingestion inside the catfish’s mouth and being spat out alive. This research contributes to a deeper understanding of size-dependent predator-prey relationships in aquatic insects and fish.

Coral reefs are being hit hard by the climate crisis, and timely interventions for their survival are a top priority. The Global Coral Tech Transfer Project enables SECORE International and the Australian Institute of Marine Science (AIMS) to implement the latest scientifically developed coral breeding techniques on a large scale across regions. The practical implementation of the project is carried out jointly and in close cooperation with Dominican Republic-based partner FUNDEMAR, combining Australian technology, Caribbean coral breeding science, and in-depth experience in implementing restoration efforts successfully. The goal is to create a comprehensive inventory of efficient and complementary methods, tools, and technologies to boost reef resilience worldwide. 

The tidal environment of mangrove forests serves as nurseries for many fish species. Researchers at the University of Gothenburg have measured carbon dioxide and oxygen levels in 23 of world’s mangrove areas. The study sends out a warning that these ecosystems are increasingly threatened as sea temperatures continue to rise.

Deep-sea waters are warming due to heat waves and climate change, and it could spell trouble for the oceans’ delicate chemical and biological balance. A new study demonstrates that the microbes may already be adapting well to warmer, nutrient-poor waters. Researchers predict that these surprisingly adaptable archaea will play an important role in reshaping ocean chemistry in a changing climate. 

Herring from different parts of the Baltic Sea belong to distinct populations genetically adapted to local differences in salinity and temperature. However, these populations can also mix with each other, according to a new study by researchers from Uppsala University, Stockholm University and the Swedish University of Agricultural Sciences. These results have important implications for the management of the Baltic herring. The study is published in the Proceedings of the National Academy of Sciences.
