Canyon effects structure fin whale feeding aggregations at Southern Ocean feeding grounds

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Large fin whale feeding aggregations at Southern Ocean feeding grounds are one of the most striking predator–prey phenomena in the post‐whaling era, representing a visible sign of recovering large whale populations. Yet, the mechanisms shaping their occurrence have not yet been studied. We investigate spatial patterns of fin whale distribution

From barrier to gateway: Climate‐facilitated expansion of thaliaceans in the Arctic Ocean

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Thaliaceans (doliolids, pyrosomes, salps) play fundamental roles in global carbon cycling and pelagic food webs through high filtration rates and rapid reproduction. Despite their prevalence, they are virtually absent from the Arctic Ocean. This paper explores the ecological, physiological, and historical factors that may have contributed to ...

Population and herbarium genomics provide a comprehensive framework for a revision of Microcoleus (Cyanobacteria)

Journal of Phycology, Volume 62, Issue 2, Page 454-476, April 2026.
Abstract Microcoleus is a cosmopolitan, filamentous cyanobacterium and a key component of biological soil crusts—complex microbial communities essential for primary production in diverse terrestrial environments. Here, we performed a taxonomic revision of several species of Microcoleus based on a large population genomic dataset.
