TL;DR: H2S may serve as an O2 sensor/transducer in the vascular responses to hypoxia, and in this model, the concentration of vasoactive H2S in the vessel is governed by the balance between endogenous H 2S production and its oxidation by available O2.

TL;DR: The results suggest that declines in a critical foundation species may have already impacted the intertidal community in the Gulf of Maine and underscore the importance of anticipating not only changes in diversity but also changes in the abundance and identity of component species, as strong interactors like foundation species have the potential to drive cascading community shifts.

TL;DR: Results show that H(2)S is a phylogenetically ancient and versatile vasoregulatory molecule that appears to have been opportunistically engaged to suit both organ-specific and species-specific homeostatic requirements.

TL;DR: H2S is a phylogenetically ancient gasotransmitter in non-mammalian non-vascular smooth muscle and that it serves as an oxygen sensor/transducer, mediating the effects of hypoxia.

TL;DR: The results suggest this butterfly spread out from eastern Europe to occupy every continent except South America and Antarctica, with the timing of many of these events coinciding with human activities—migration, trade, and the development of crop cultivars that serve as food plants for the butterfly larvae.
