Abiotic Factors are the nonliving factors in an ecosystem. Climate change poses a major threat to coral reefs. Local Threats to Coral Reefs Coral Reefs are suffering from natural and anthropogenic threats. What we haven’t known much about is the way environmental factors affect coral reefs in the absence of people. Physical Trauma. The journal is also open to review articles notes and perspectives on major scientific problems concerning coral reefs. [1] Significant buffering of the impact of tsunamis by coral reefs is suggested by limited observations and some If you’re interested in other threats of coral reefs, I’d Recommend reading 10 Major Threats to Coral Reefs. The study looked at coral reefs around Christmas Island, where there's been extensive phosphate mining for around 100 years.. Lead researcher Dr. Jennie Mallela says in … Coral Reefs are one of the most diverse ecosystems in the world, but their survival has been compromised because of human actions. It publishes analytical and theoretical papers on both modern and ancient reefs, and encourages the search for theories about reef structure and dynamics, and the use of experimentation, modelling, quantification and the applied sciences. But corals are threatened by pollution and climate change. Necessary Abiotic Factors: Water Temperature- 23-29 degrees Celsius Saltinity- 32-40% Water Depth- 25m or less is a term used to describe significant changes to the chemistry of the ocean. Abbreviation: Coral Reefs. pH. Presumably there are certain physical drivers for how a healthy reef community grows. As the environment of coral reefs naturally is very stable, reefs are easily affected by sudden changes of abiotic factors, like salinity, temperature, oxygen content, and water transparency. The industrial sector is one factor because coral reefs are destroyed. Their special requirements to survive also make them relatively sensitive to change. Increasing industrial growth, especially in rural areas it can have a negative effect on the surrounding environment. In fact, coral reefs can support 650 coral and 1000 species in one location! 2003; Bellwood et al. Coral reefs are one of the most biologically diverse ecosystems on earth, rivaled only by tropical rain forests. Contributing factors that increase greenhouse gases in the atmosphere include burning fossil fuels for heat and energy, producing some industrial products, raising livestock, fertilizing crops, and deforestation. 2005). Coral reefs are a precious resource in the ocean because of their beauty and biodiversity. Coral reefs attract millions of tourist and scuba divers annually. Coral has a multitude of uses as a construction tool. Threats to Coral Reefs. Nearly two-thirds of coral reefs in the Caribbean are threatened by human activities. Many anthropogenic influences are resulting in the degradation and destruction of coral reefs causing loss of biodiversity, essential food supplies and economic revenue. The total global value of reef based recreation and tourism is estimated to be US$9.6 billion per year (“The Economic Impact Of Coral Reefs”, 2015). Coral reefs are “low input ecosystems” concerning flow of matter (D'Elia and Wiebe, 1990). While the net impact of lower pH on coral reefs continues to be examined, decreases in pH can reduce the calcification rates of corals and other calcifying organisms (Ries et al. Coral reefs reduce tsunami impact in model simulations Catherine M. Kunkel,1 Robert W. Hallberg,2 and Michael Oppenheimer3 Received 15 August 2006; revised 12 October 2006; accepted 8 November 2006; published 14 December 2006. Threats to coral reefs come from both local and global sources. Coral reefs aren’t just destinations for tourists. Coral reefs are in decline in the U.S. and around the world. Part C: Impact of Climate Change on Coral Reefs Scientists monitor coral health in a variety of ways. (Coral Reefs, 2011, in press) challenge our interpretations of the changes in coral cover observed on the Great Barrier Reef (GBR) between 1986 and 2004 (Sweatman et al. (Connolly et al. Coral Reefs—Part 3. Hughes et al. The sea turtles, sea snakes, and also marine iguana will get the impact if the coral reefs disappear. Healthy coral reefs contribute to fishing and tourism, providing millions of jobs and contributing to economies all over the world. The research team identified 62 outer reefs (offshore, opposed to inner reefs which are closer to land) in the tropical Pacific Ocean that are close to human populated areas and classified these reefs into two categories – one with low exposure to human impact, and the other with high exposure to human impact. This is a remarkable statistic when you consider that reefs cover just a tiny fraction (less than one percent) of the earth’s surface and less than two percent of the ocean bottom.
