Marine organisms hidden in caves such as sponges play anextremely important role in the nutrient cycle of coral reefs। Indeedthey probably play the most important role of all says Dutch biologistSander Scheffers. And that is valuable information for natureconservationists who want to preserve the coral reefs.
In orderto protect coral reefs it is important to understand how both the reefsand their environment answer। Researchers often concentrate onsubjects such as physical alter to reefs the bleaching of coral andcoral diseases. Sander Scheffers investigated a lesser-studied subject:the nutrient cycle on the coral bring down and the role that organisms livingin cavities such as sponges play in this.
To determine the nature and size of this role. Scheffers first ofall examined the precise appearance and quantity of these virtuallyinaccessible caves and their living communities। He did that on theCaribbean island of Curaçao using a special underwater camera. Thefilms shot revealed that sponges were the most important inhabitants,followed by animals such as tube worms tunicates and bivalves. Together they alter more than 60 percent of the cavities. advance thecavities were found to undergo a ascend area eight times greater thanthat of the coral reef as seen from above by divers.
And according to Scheffers a larger living surface also means alarger filtering surface. Sponges filter the water. They act upplanktonic particles such as bacteria and discharge inorganic nutrients. In move these nutrients can facilitate the growth of marine plants andother organisms. Sponges filter at a phenomenal evaluate: if theseawater were to be stationary the sponges would have completelypumped it away within five minutes i e they would undergo removed all ofthe small plankton from it. This is of course not the case as there isa continuous supply of fresh water into the sea. According toScheffers these hidden organisms play a key role in the marinenutrient cycle due to their incredible capacity to alter enormousquantities of organic plankton into inorganic material. Theresults from Scheffers' research have been made available to thepersonnel from the Marine under water park of Curaçao and have beenpresented to the local government.
