NEW in @science.org Global tracking #MarineMegafauna shows <8% of areas used overlap w/ existing MPAs, while >75% of important areas overlapped by threats like #fishing #shipping & ocean warming - 30x30 goal will be insufficient for their conservation www.megamove.org @thembauk.bsky.social

Global tracking of marine megafauna space use reveals how to achieve conservation targets

The recent Kunming-Montreal Global Biodiversity Framework (GBF) sets ambitious goals but no clear pathway for how zero loss of important biodiversity areas and halting human-induced extinction of thre...

50 years on from the release of movie blockbuster Jaws, our shark expert @thesimslab.bsky.social @sotonoceanearth.bsky.social debates the so called 'Jaws effect', charting the fortunes of the 'great white' for @theconversation.com.

Jaws helped spur a fishing frenzy – so how have the world’s sharks fared since the 1975 release?

The film made us afraid to go back in the water. It ultimately gave sharks more to fear from us.

New research backed by the UN highlights the benefits of tracking marine megafauna for #marine #conservation 🦈

However, results reveal that proposed plans to protect 30% of the ocean by 2030 will be insufficient for their conservation.

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.

Unlocking the mystery of baby #whaleshark birthing grounds - Extreme environments like #OMZs provide safety from predators & a rich food supply, crucial for neonate survival.

(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
