This study uses predator\u2013prey population models to map the thresholds where that shift occurs and to identify management levers that keep ecosystems stable. By varying growth, grazing, and mortality rates, the simulations reveal parameter \u2018windows\u2019 that maintain balance\u2014and warn where small changes push the system past a tipping point.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical takeaway for coastal managers is twofold. First, monitor both urchins and seagrass, not just one or the other: stability depends on their interaction. Second, apply targeted measures\u2014controlled harvests, protecting urchin predators, or reducing nutrient inputs that fuel algal competition\u2014before thresholds are crossed. The paper also calls for more field data to refine local parameter values so that models translate into site\u2011specific action plans.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With seagrass meadows among the planet\u2019s most efficient blue\u2011carbon sinks and nurseries for fisheries, preventing barren patches advances SDG 14 (healthy coasts) and SDG 13 (climate mitigation), and supports SDG 15 through habitat conservation. Turning theory into early\u2011warning guidance helps decision\u2011makers act in time to protect both biodiversity and livelihoods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Read full paper here: <a href=\"https:\/\/www.scopus.com\/record\/display.uri?eid=2-s2.0-85215589357&amp;origin=recordpage\">https:\/\/www.scopus.com\/record\/display.uri?eid=2-s2.0-85215589357&amp;origin=recordpage<\/a><\/p>\n\n\n\n<h1 class=\"wp-block-heading\"><strong>Credits<\/strong><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Universitas Padjadjaran authors: Imam Cahyana; Wahyuniar Pamungkas; Subiyanto; Donny Prihadi; Sheila Zallesa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other institutions involved: \u2014.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hashtags: <\/strong>#UnpadResearch #SDG14 #Seagrass #SeaUrchin #EcosystemModeling<\/p>","protected":false},"excerpt":{"rendered":"<p>Sea urchins are vital herbivores in seagrass meadows, but when their numbers surge, grazing can flip a thriving bed into a barren state.
