Narrow-ridged finless porpoises were long assumed to be mostly solitary species with little allomaternal interaction. In a new study, researchers from Kindai University found four infant porpoises swimming with non-mother adults. The functions of these interactions are unclear. It is possible that they reduce swimming effort for infants and help young females learn to interact with infants before having their own offspring. These findings are valuable for wildlife conservation and rehabilitation of abandoned infant porpoises.

How is carbon metabolized and processed in different ecosystems? In a recent study published in the journal Communications Earth & Environment, researchers led by Joely Maak, the study’s first author and researcher in the Cluster of Excellence “The Ocean Floor – Earth’s Uncharted Interface”, examined the carbon cycle in a unique marine ecosystem.

An interim update to the landmark State of the World’s Migratory Species of 2024 warns that 49% of migratory species populations protected under a global treaty are declining, up 5% in just two years, and 24% of species face extinction, up 2%. The new warnings will be presented to the 15^th Meeting of the Conference of the Parties to the Convention on the Conservation of Migratory Species of Wild Animals (CMS COP15), a legally-binding UN treaty, in Campo Grande Brazil March 23-29.

The compilation of academic studies provides a timely examination of new tools, collaborations, and discoveries that have furthered understanding of the role and ecosystem impact of marine diseases — and how to manage them.

gathering in unusually large groups and engaging in mating behaviour.

The footage, gathered between 2019 and 2023, provides one of the most detailed records of harbour porpoise mating behaviour ever documented in UK waters.

Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbour such a wide range of stripes, spots and patterns? A study conducted by the University of Liège reveals that this explosion of colour patterns is not the result of chance. The more species a reef is home to, the more varied the patterns, and fish from different oceans often end up looking alike, guided by the same deep biological constraints.

A research team led by Prof. XU Yigang from the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences (CAS) and Prof. DENG Chenglong from the CAS Institute of Geology and Geophysics conducted a study of the Yanshan Scientific Drilling Project (YSDP-4) drill core, with a drill depth of 1497.5 meters. The core was recovered from the lacustrine Jiufotang Formation in northeastern China.

The year-long algal bloom along the South Australian coastline has not only devastated marine life and triggered health risks for humans and pets: it has also had a significant psychological impact on local residents, according to new research.
