Modified fin morphology in mackerel icefish (Champsocephalus gunnari) may indicate nesting behaviour

Journal of Fish Biology, EarlyView.
Abstract Monitoring reproductive traits in Southern Ocean species is challenging. Males in some channichthyids thicken the epithelium along their anal fins to aid nest construction. This study presents initial evidence that the only commercially harvested channichthyid, mackerel icefish (Champsocephalus gunnari), exhibits modifications to their anal ...

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

Journal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Unilateral Action on Climate Change and the Moral Obligation to Take Leadership

Journal of Social Philosophy, EarlyView.
ABSTRACT We claim that a moral obligation to take climate leadership by means of unilateral mitigation depends on the existence of a plausible follow‐the‐leader mechanism whereby unilateral mitigation by some increases the probability of sufficient mitigation by others to avert catastrophic climate impacts.

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

Journal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from
