R. Steinsd\u00f3ttir, a postdoctoral researcher in the Hatter Department of Marine Technologies, under the joint guidance of Dr. Derya Akkaynak (COLOR Lab) and Dr. Miguel J. Frada (Hebrew University),\u00a0employed an intensive sampling protocol over multiple 24-hour cycles across different seasons. The team found that reefs filter bacteria during daylight hours while hosting dramatically increased populations of microscopic predators at night.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">This research, conducted in collaboration with the Interuniversity Institute for Marine Sciences in Eilat and published in Science Advances, suggests that tracking these microbial rhythms could provide a sensitive &#8220;pulse meter&#8221; for reef ecosystem health.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>For the full story and detailed findings, see coverage in:<\/strong><\/p><ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1.5 [li_&amp;]:gap-1.5 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-2 pl-8 mb-3\"><li class=\"whitespace-normal break-words pl-2\"><a class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.timesofisrael.com\/new-israeli-research-shows-coral-reefs-shape-the-ebb-and-flow-of-local-microbial-life\/\" rel=\"nofollow noopener\" target=\"_blank\">Times of Israel &#8211; Complete article<\/a><\/li><li class=\"whitespace-normal break-words pl-2\"><a class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.israelhayom.co.il\/tech\/research\/article\/19576851\" rel=\"nofollow noopener\" target=\"_blank\">Israel Hayom (Hebrew)<\/a><\/li><\/ul><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>Scientific paper:<\/strong> <a class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/doi.org\/10.1126\/sciadv.ady9534\" rel=\"nofollow noopener\" target=\"_blank\">Science Advances<\/a><br \/><br \/>Photo: Tom Shlesinger<\/p><\/div><\/div><\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>The study reveals how Gulf of Eilat reefs shape surrounding marine ecosystems hour by hour<\/p>\n","protected":false},"author":3,"featured_media":42688,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"elementor_header_footer","format":"standard","meta":{"_acf_changed":false,"_eb_attr":"","footnotes":"","_wp_rev_ctl_limit":""},"categories":[103,105],"tags":[],"class_list":["post-42681","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","category-news-archive","entry","has-media"],"acf":[],"_links":{"self":[{"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/posts\/42681","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/comments?post=42681"}],"version-history":[{"count":0,"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/posts\/42681\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/media\/42688"}],"wp:attachment":[{"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/media?parent=42681"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/categories?post=42681"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/marsci.haifa.ac.il\/en\/wp-json\/wp\/v2\/tags?post=42681"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
