Dietary adaptations along the northern limit of distribution: what does the smooth snake Coronella austriaca eat in Norway? Metabarcoding of stomach content and visual analysis of faeces

open access: yesWildlife Biology, Volume 2025, Issue 5, September 2025.
Understanding how species survive at their poleward limits of distribution is of interest in species conservation, particularly in light of global warming and predictions of shifting distributions of both predators and prey species. How species adapt to high latitudes and to future climate changes will be impacted both by direct interactions with the ...

Molecular Phylogenetics of Thecata (Hydrozoa, Cnidaria) Reveals Long-Term Maintenance of Life History Traits despite High Frequency of Recent Character Changes [PDF]

open access: yes, 2017
Two fundamental life cycle types are recognized among hydrozoan cnidarians, the benthic (generally colonial) polyp stage either producing pelagic sexual medusae or directly releasing gametes elaborated from an attached gonophore.
