The global importance of mesopelagic fish is increasingly recognised, but they remain poorly studied. This is particularly true in the Southern Ocean, where mesopelagic fishes are both key predators and prey, but where the remote environment makes sampling challenging. Despite this, multiple national Antarctic research programs have undertaken regional sampling of mesopelagic fish over several decades.

Aims: To assess the prevalence and correlates of non-optimal secondary medical prevention in patients with stable CAD.
Methods: We included 4184 consecutive outpatients with stable CAD.
Article Synopsis
- The text discusses the need for practical methods to define and evaluate species flocks, particularly in the Antarctic shelf's benthic fauna.
- The authors apply five criteria to assess various taxa, focusing on historical criteria of endemicity, monophyly, and species richness due to practical limitations.
- They identify nine definitive species flocks, suggest eight additional "core flocks" for further ecological study, and challenge the idea that marine species flocks are uncommon.
Article Synopsis
- The study presents a new Guanidine-based ancient DNA extraction method for analyzing fluid-preserved specimens from museum collections, particularly targeting the genus Orestias, a group of cichlid fish known for their complex taxonomy.
- DNA was successfully extracted from both living and extinct species of Orestias, including the extinct O. cuvieri, using type specimens stored in a museum in Paris, enabling a re-evaluation of the species' relationships.
- The researchers created a detailed molecular phylogeny of Orestias, identifying four distinct clades and redefining their taxonomic relationships, while noting that the mulleri complex appeared to be polyphyletic, indicating multiple evolutionary lineages.
