Shark Research Takeover – Greetings from David Sims 🦈🦈🦈. This week we’ll be tweeting about our research on shark movement ecology, behaviour & conservation in relation to Climate Change & human threats (fishing, shipping) & our latest tagging expeditions to Azores. #MBASharks

Our David Sims OCEAN DEOXYFISH project explores how ocean deoxygenation & warming alters shark space-use & vulnerability to fishing. This animation by Nick Humphries shows global levels of Dissolved Oxygen & where Oxygen Minimum Zones occur (Low DO/OMZs shown in blue) #MBASharks

Tracking sharks’ responses to Ocean Deoxygenation means we also study responses in normoxic habitats - In the Azores we record movements, behaviour & speeds of blue & mako sharks with @OkeanosUAc Whilst fishing we were excited to be joined by this curious blue shark. #MBASharks

Check out our new ‘DOME’ tags developed by Nuno Queiroz ElectricBlue MOVE MBA - Marine Biological Association for monitoring dissolved oxygen, temperature, depth and accelerometry of sharks for our ocean warming and hypoxia research. #MBASharks

PhD student Freya Womersley University of Southampton funded by Natural Environment Research Council Freya's research uses the Global Shark Movement Project collaborative big datasets to understand present-day distributions of whale sharks to estimate future niches in the changing ocean environment.#MBASharks

Our 2nd year University of Southampton PhD European Research Council (ERC) funded student Matt Waller Matt Waller is using satellite tracking technologies to unravel the impact of declining ocean oxygen on the biology and ecology of large oceanic shark species. #MBASharks

#SharkAwarenessDay Focus on endangered shortfin mako sharks whose popul'ns are decimated due to overfishing – this brief film on new #OA research in #JFB measures mako swim speeds & highlights what climate-driven ocean deoxygenation will mean for them buff.ly/43tqZYu

A huge THANK YOU to all of our fantastic collaborators David Sims had the pleasure to work with over the last 23y making possible our discoveries on foraging, climate impacts, search scaling laws, fisheries overlap & marine traffic collisions with giant sharks. #MBASharks

Basking sharks are what now?! New paper led by Dr Haley Dolton (she/her) where we document regional endothermy in our favourite giant filter feeding sharky 🔥. Interesting implications for evolution and ecological advantages of regional endothermy; we thought it was only seen in apex 🦈&🐟1/3

We combined anatomical exploration of stranded specimens and biologging; results very similar to data for lamnid sharks like whites and makos. Suggests RE more common in lamniformes than we thought, and helps explain basking 🦈 migrations. Future responses to ocean warming??? 2/3

nature.com/articles/s4155… Excellent new paper on a framework to develop a 'dynamic human footprint', critical to understanding human-wildlife interactions! w/ @Diego_EllisSoto David Sims among others. NatureEcoEvo

New paper led by Camrin Braun out today in Science Advances 🚨 "Widespread habitat loss and redistribution of marine top predators in a changing ocean" science.org/doi/10.1126/sc… Summarized nicely by Woods Hole Oceanographic Institution (WHOI) whoi.edu/press-room/new…

Very unfortunate article by Bjorn Lomborg misleading the world, using flawed and cherry-picked data and ignoring the dramatic reality impacting the lives of hundreds of thousands. For a rationale: follow the money... wsj.com/articles/clima…

The fastest #shark? New directly measured swim speeds of shortfin #mako show a burst speed of 5 m/s, among the fastest speed yet recorded for free-swimming sharks, tunas and billfishes! David Sims MBA - Marine Biological Association doi.org/10.1111/jfb.15… #JFB
