Improving species-based area protection in Antarctica

Laura M. Phillips et al.

Summary: This study focuses on the type locality criterion for area protection in Antarctica and reveals the inadequacy of the current protected areas network. By analyzing a comprehensive database of type localities, the study identifies numerous unprotected areas that should be considered for future conservation efforts. The authors propose alternative approaches to deploy the type locality criterion, such as systematic conservation planning and emphasis on species habitat.

Climate drives long-term change in Antarctic Silverfish along the western Antarctic Peninsula

Andrew D. Corso et al.

Summary: This study uses a 25-year time series to demonstrate how variations in sea ice coverage and ocean temperatures affect the larval abundance of an important forage fish, the Antarctic Silverfish. The findings provide insights into the potential impacts of current reductions in this keystone species on the vulnerable pelagic ecosystem along the western Antarctic Peninsula.

Antarctic ecosystems in transition - life between stresses and opportunities

Julian Gutt et al.

Summary: Experts synthesized important findings on the impact of environmental change on biological processes in Antarctica during the second decade of the 21st century, identifying ten key messages with stakeholder-relevance and high impact for the scientific community. Most Antarctic biotas are considered vulnerable to environmental change due to multiple stresses, narrow tolerance ranges, and migration barriers, with important ecosystem functions and biodiversity patterns already shifting. Confidence assessment revealed an intermediate level of 'scientific understanding', highlighting the need for continued efforts to inform protection measures for Antarctic ecosystems.
