🧵2/6 Using year-long #biologging, we recorded 577 breaches within 442 breaching events across four individuals. Events commonly consisted of a single breach, but in 21% comprised multiple breaches in short succession. @haleydolton.bsky.social @nunoqueiroz29.bsky.social @thesimslab.bsky.social

Multi-panel figure showing depth (m) over time (Δt, seconds) of basking shark underwater breaching profiles aligned around a surface event at time zero. Four panels show breaching trajectories showing single (n = 349, double (n = 64), triple (n = 17), and quadruple (n = 11) breaches. Each panel contains multiple overlaid individual trajectories shown as semi-transparent coloured lines, with individuals displayed in different colours.

🚢 From static to dynamic: how can we protect marine life from shipping strikes? Turing researchers have published a paper calling for a more flexible approach to marine protected zones to prevent shipping strikes on marine animals. Learn more: bit.ly/4v4wz2L

Call for dynamic regulation of our oceans to reduce whale strikes

A new paper warns that traditional marine protected zones are an inefficient way to prevent shipping strikes on marine animals and a more flexible approach i

Herculean collation of >12K megafauna tracks, >100 species, reveals 75% overlap of critical habitats with shipping, fishing, pollution or warming. Protection targets not enough to safeguard megafauna. New paper in @science.org, led by @anammsequeira.bsky.social 👇 📸silvana-palacios,daniel-torobekov

New research from @thesimslab.bsky.social in @ecol-evol.bsky.social - 🦈🌊 Unlocking the mystery of baby #whaleshark birthing grounds - Extreme environments like #OMZs provide safety from predators & a rich food supply, crucial for neonate survival. doi.org/10.1002/ece3... @thembauk.bsky.social

(a) Recorded sightings of whale shark neonates globally (black points). (b) Image of neonatal and adult whale sharks from Large Marine Vertebrates Research Institute Philippines group (b) and Marty Snyderman (b). (c) Whale shark neonates and sea surface temperature (SST, °C averaged for 2005–2019). (d) SST recorded from neonate locations and 10 randomised runs. (e) Whale shark neonates and Chlorophyll-a (Chl-a, mg m3 averaged for 2005–2019). (f) Chl-a at 0 and 100 m depths recorded from neonate locations and 10 randomised runs. (g) Whale shark neonates and current velocity (UV) at 0 m depth (ms−1, averaged for 2005–2019). (h) UV recorded from neonate locations and 10 randomised runs. (i) Whale shark neonates and dissolved oxygen (DO) concentration at 100 m depth (μmol L−1, averaged for 2005–2019). (h) DO concentrations at 0 and 100 m depths recorded from neonate locations and 10 randomised runs. In (d, f, h) and (j) each point represents a single sighting or randomised location, the solid black line is the median value of randomised locations, the dashed black line the median of the observed sightings for each depth, and the violin displays the density distribution of all locations. IUCN whale shark distributions are shown in white in each map and with a black outline in (a).

NEW PAPER - we think we've discovered an open-ocean nursery for endangered shortfin #mako #sharks in the SE Pacific Ocean..... only trouble is, it's in a Global Fishing Hotspot - likely exacerbating popn declines already occurring @thembauk.bsky.social OA here: www.nature.com/articles/s41...
