The research, conducted by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science, spans over two decades and documents cascading ecological disruptions, underscoring the crucial role apex predators play in maintaining ocean health.<\/p>\n<p>Using a combination of long-term boat-based surveys of shark sightings, citizen science observations on Cape fur seals, and Baited Remote Underwater Video Surveys (BRUVS) of fishes and small sharks, the study provides evidence that the absence of Great white sharks has triggered significant shifts in the marine food web.<\/p>\n<p>\u201cThe loss of this iconic apex predator has led to an increase in sightings of Cape fur seals and sevengill sharks, which in turn has coincided with a decline in the species that they rely on for food,\u201d said Neil Hammerschlag, Ph.D., the study\u2019s lead author. Hammerschlag conducted the research while at the Shark Research and Conservation Program at the University of Miami Rosenstiel School. \u201cThese changes align with long established ecological theories that predict the removal of a top predator, leads to cascading effects on the marine food web.\u201d<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.enn.com\/articles\/76237-ecosystem-disrupted-following-the-disappearance-of-great-white-sharks-new-study-finds\">Environmental News Network<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/5-692\/\">Ecosystem Disrupted Following the Disappearance of Great White Sharks, New Study Finds<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[4168,575,18357,18358],"class_list":["post-138578","post","type-post","status-publish","format-standard","hentry","category-news","tag-ecosystem","tag-environmental-news-en","tag-great-white-shark","tag-ocean-health"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/138578","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=138578"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/138578\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=138578"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=138578"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=138578"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
