{"projectrec":{"ProID":2679,"StandardTitle":"Orca Acoustic Project","OrigTitle":"Predation interactions between orca's <i>(Orcinus orca)</i> and South-American sea lions <i>(Otario flavescens)</i> along the coast of Patagonia, Argentina","Acronym":null,"AbstractEnglish":"Orcas <i>(Orcinus orca)</i> hunt a wide diversity of prey, marine mammals with pinnipedia as a wellknown food source. \r\nAt Punta Norte, orcas have been observed to forage on sea lions by intentional stranding. \r\nSea lions breed from December to April and orcas come to feed in March and April when pups start to move into the water.\r\nThe aim of the study was to investigate the how this predatory interaction had changed between 1988-1989 and 2003-2004. We also controlled for predator's preferences and sea lion anti-predatory adaptations.","AbstractOtherLang":"Orka's <i>(Orcinus orca) </i>hebben een grote diversiteit aan prooi waaronder o.a. robben. In Punta Norte, Peninsula Valdes, kunnen we zien hoe de orka's jagen op Zuid-Amerikaanse zeeleeuwen met een unieke jachttechniek: \"intentionele stranding\". \r\nZeeleeuwen worden geboren tussen december en februari, maar de orka's komen pas jagen in maart - april, wanneer de pasgeboren zeeleeuwen leren zwemmen.\r\nHet doel van dit project was de jachttechnieken van de orka's te bestuderen via akoestische opnames en de predator - prooi interactie tussen de orka's en de zeeleeuwen te omschrijven. Nadien werden vergelijkingen gemaakt met de periode 1988-1989 om informatie te bekomen over de evolutie van deze unieke jachttechniek van orka's.","DateLastModified":{"date":"2025-07-02 08:33:20.809226","timezone_type":1,"timezone":"+02:00"},"ParentProID":null,"BeginYear":2003,"EndYear":2005,"BMonth":null,"EMonth":null,"BeginMonth":null,"EndMonth":null,"OrigTitleLangCode":"en","OrigTitleLangID":15,"OrigTitleLangNL":"Engels","OrigTitleLang":"English","OtherAbstractLangCode":"nl","OtherAbstractLangID":41,"OtherAbstractLang":"Dutch","OtherAbstractLangNL":"Nederlands","Progress":"Completed","ProgressNL":"Afgelopen","PublicFlag":1,"CheckedFlag":0,"ND":"2008-08-01","UD":"2008-08-01","DMPFlag":0,"Budget":null,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":null,"ProPartID":9857,"PublicFlag":1,"OrigNameLangCode":"es","OrigNameLangID":17,"FullOrigName":"Fundación Marybio","Line1":"Kladdenbergstraat 34","Line2":"2650 Edegem","Line3":null,"Line4":null,"InsID":9452,"FullStandardName":"Stichting Marybio","Role":"Co-ordinator","RoleID":7,"EncAddress":"Kladdenbergstraat 34, 2650 Edegem, Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[],"pastpers":null,"subpers":null,"projects":null,"urls":null,"pictures":null,"published":null,"affrefs":null,"collections":null,"thesterms":null,"taxterms":null,"geoterms":null,"thestermsFRIS":null,"nXtins":null,"previns":null,"spcols":null,"resmessage":"no id specified","complete":0,"participantrec":null,"peerrevs":null,"urlmaps":null},{"instituterec":{"Acronym":"ETOX","ProPartID":9858,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Vrije Universiteit Brussel; Faculty of Sciences; Department of Biology; Ecotoxicology and Polar Ecology Laboratory","Line1":"Pleinlaan 2","Line2":"1050 Brussel","Line3":null,"Line4":null,"InsID":1488,"FullStandardName":"Vrije Universiteit Brussel; Vakgroep Biologie; Laboratorium voor Ecotoxicologie en Polaire Ecologie","Role":"Co-ordinator","RoleID":7,"EncAddress":"Pleinlaan 2, 1050 Brussel, Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[],"pastpers":null,"subpers":null,"projects":null,"urls":null,"pictures":null,"published":null,"affrefs":null,"collections":null,"thesterms":null,"taxterms":null,"geoterms":null,"thestermsFRIS":null,"nXtins":null,"previns":null,"spcols":null,"resmessage":"no id specified","complete":0,"participantrec":null,"peerrevs":null,"urlmaps":null},{"instituterec":{"Acronym":"MACN","ProPartID":9859,"PublicFlag":1,"OrigNameLangCode":"es","OrigNameLangID":17,"FullOrigName":"Musea Argentino de Ciencias Naturales \"Bernardino Rivadavia\"","Line1":"Av.
