First insights into the shortfin mako shark (Isurus oxyrinchus) fine-scale swimming behaviour
Royal Society Open Science, 2023 As regional endotherms, lamnid sharks can sustain high cruising speeds and perform frequent speed bursts. However, since endothermy comes with high energetic costs, lamnids may adopt different swimming strategies to manage their energy budget ...

Entrainment Makes Pollution More Likely to Weaken Deep Convective Updrafts Than Invigorate Them
Geophysical Research Letters, 2023 Are the results of aerosol invigoration studies that neglect entrainment valid for diluted deep convective clouds? We address this question by applying an entraining parcel model to soundings from tropical and midlatitude convective environments, wherein
