🚨New Study Alert 🚨: "Evidence of cascading ecosystem effects following the loss of white sharks from False Bay, South Africa" : frontiersin.org/journals/marin… Please share
There is increasing evidence of the critical role that #sharks play in maintaining healthy marine ecosystems. New research from False Bay, South Africa, reveals how the disappearance of #greatwhitesharks is disrupting #biodiversity and reshaping the ecosystem. Read more:…
Los tiburones blancos son especies clave en sus ecosistemas, controlando poblaciones de depredadores más pequeños para que no destruyan las poblaciones de presas pequeñas
🚨This video highlights key findings from our two-decade study providing evidence of how the absence of an apex predator is reshaping the marine ecosystem. Study 🔗: frontiersin.org/journals/marin…
63% of the area tracked marine megafauna covered is used 80% of the time as important migratory corridors or residence areas. Unfortunately, 30% protection targets will be inadequate for their effective conservation in light of global threats assessed.
New massive collaborative paper out in @ScienceMagazine led by @AnaMMSequeira @MegaMove_Org - We tracked 15,845 individuals from 121 species to evaluate space use of highly mobile marine megafauna. science.org/doi/10.1126/sc…
So proud to contribute to this important paper. Please check it out!
📢A MegaMove milestone has just been published in @ScienceMagazine! With ~380 collaborators from 50 countries, we mapped the movements of 12k+ marine megafauna to identify key habitats 🌊🐋🦈 @pewenvironment @MegaMove_Org @EcoEvo_ANU @uwaoceans sequeiralab.com/news/megamove-…
When Sharks Return, Reefs Respond Scientists found that when sharks return, their presence alone — not just their appetite — changes the way prey live, feed, and reproduce, transforming the reef. forbes.com/sites/melissac…
🚨 IOOS FUNDING AT RISK – TAKE ACTION BY APRIL 26!🚨 The President’s FY2026 Budget proposes completely eliminating funding for U.S. IOOS Regional Observations. This funding directly supports SECOORA and their partners, including the FACT Network. See 👇 on how YOU can help

The Ecological Fallout Of Losing White Sharks In South Africa When top predators vanish, everything shifts. False Bay’s white shark disappearance has set off a chain reaction affecting prey, competitors, and habitats. forbes.com/sites/melissac…
Just hit a professional milestone: my #research has now been cited over 10,000+ times. Grateful to colleagues, students & mentors who’ve made it possible. Honored to contribute to #science—especially when evidence-based info matters more than ever

Following the loss of white sharks from False Bay, both seals and sevengill sharks have increased in relative abundance, coinciding with declines in small fish that seals feed on and smaller sharks that sevengills prey upon. Illustration: Kelly Quinn
