And we should. That’s like saying that -we claim we’re dirtying up the house by partying and some of us are saying we need to clean the kitchen and bathroom or the party is gonna start to stink
It's nature in balance, food versus numbers, Crown of thorns starfish eat vast amounts of coral resulting in less food, crown of thorns star fish numbers plummet resulting in the coral reefs recovering, resulting in more food for crown of thorns, this cycle could take 100 years, how long has clever clogs scientists been studying it?
Thank you Dr Ridd. Well done on this presentation. > This is a purely subjective thought. In the past, and again at the beginning of this video I wondered. Does this natural culling of sections of the reef by the COT actually allow an opportunity for some corral polyps to gain a foothold where it may otherwise be dominated by a stronger species thus contributing to the overall diversity. Other natural phenomena such as cyclones may also play a positive role. I know in the instance of cyclones, what appears like short term damage and doom and gloom usually results in a regrowth with positive long term implications. I have witnessed this personally in the mangrove ecosystems in FNQLD. In short; Is this actually beneficial to the long term survival of not just the different polyp but other species in that food chain? > I agree; as humans we are often far to eager to play God and tinker. If it wasn't broken then we can fix that and make it broken lol > P.S. Should we cull off parrot fish for all of corral they consume in a year? I am uncertain about estimates, but a single large parrot fish can turn about 200kg of corrals into corral (Calcium Carbonate) sands per year; just one parrot fish.
Thank you once again for the support , I would agree that the entire eco system is connected and it would reset the corals along with the food chain that follows . Perhaps Parrotfish feeding on coral is like pruning and it contributes alot to the sand substrate
@@reefrebels Thank you for the reply. I was thinking about my own experiences with "Perhaps Parrotfish feeding on coral is like pruning and it contributes alot to the sand substrate" after the video and we tend to see the beginnings of new reef taking hold on the broken pieces of corral over the corral sands next to the main reef structures. I don't believe the reef forms over any kind of bedrock and the fine silts on the ocean bottom would be far from ideal, so the corral sands as well as the larger "Broken off" pieces may very well create the stable foundation for the reef to spread over. It's not unusual to see small often singular blocks of corral growth (particularly brain corrals) scattered over the deeper corral sands next to the main reef. I suspect in time some will grow into the larger "bommies" that we see surround the main reef. > The Parrot part reminded me of a land based example of this where the Black Cockatoo prunes the seed bearing branches from our native trees. They leave the seeds/berries sit on the ground and come back later to feed on them. Not all are eaten, but the tree has become relent upon this pruning as part of the seed germination process. I cant recall the name of these trees off the top of my head.
I've been asking this question since I was at primary school in the seventies. " if our records are only a hundred years or so, how can we be sure that this isn't part of the natural world at play and we're not interfering?" I should have never listened to my parents and followed my heart to become a marine biologist instead of a carpenter.
i think you are better off as a carpenter , can you see how corrupt the science institutions are now and marine biologists are all in on it - no threats no funds
