{"product_id":"trends-in-shark-catches-von-ola-andreas-lundemo","title":"Trends in shark catches","description":"\u003cp\u003eA retrospective statistical analysis of historical  catch data for sharks captured in protective gill  nets along the KwaZulu-Natal coastline was carried  out with the aim to investigate the frequency of  shark catches in relation to changing phases of the  moon and season. All species showed seasonal trends  and fluctuating sexual proportion, suggesting  sexually segregated migratory behavior and variation  in sexual regimes for some shark species. Significant  changes in catch rates in relation to shifting phases  of the moon were found for all individual species and  sex analyzed, indicating that light intensity of the  moon, likely in consortium with other environmental  predictors, influences shark activity and behavior.  However, no conclusive pattern was apparent that  could indicate a generalized relation between shark  genera or common habitat and specific lunar phases,  although it is possible that the behavioral ecology  of distinct species may provide explanations for the  affinity to a particular moon phase. Findings point  to which shark species may most likely be caught  under specific moon phase conditions and time of the year.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838363714\"\u003e\u003ch3\u003eSeasonal and lunar trends of sharks caught in the protective gill nets off KwaZulu-Natal, South Africa\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838363714","offer_id":39472648683613,"sku":"9783838363714","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/72b36ceb-3e7b-4848-a348-fd21b392055d.jpg?v=1758952638","url":"https:\/\/shop.autorenwelt.de\/en\/products\/trends-in-shark-catches-von-ola-andreas-lundemo","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
