coral reefs. Needs to be 6 pages. Please no plagiarism. One of the most productive, diverse, and valuable ecosystems on earth (Notes), coral reefs are the highest primary producers of all ecosystems. . They are storehouses of immense biological, economic, and cultural wealth and are thus of great importance and the subject of hundreds of research papers, global symposiums, monitoring networks (Jackson et al., 2012). . Both documents focus on predicting how increasing sea temperatures and ocean acidification can lead to the collapse of these systems in the future. . . Both papers discuss the mechanisms at play, including increasing temperatures resulting in more bleaching events and disease and ocean acidification from increased CO2 uptake reducing reef growth and calcification. . It is evident from these research papers that climate variation and rates of change of CO2 are the drivers behind the potential collapse and point to the anticipated future global warming scenarios leading to such failure as predicted by the Intergovernmental Panel on Climate Change (ICCP) (ICCP, 2007). . It is just a matter of when and where.
The first paper, ENSO, delivers a palaeoecological approach by investigating the Pacific reef-building framework’s history and comparing it to current climate variability and CO2 emissions trends. . . . This primary field research consisted of obtaining push core samples from reef habitats in the Pacific Panama region. . From these samples, the researchers could then clearly define a hiatus in coral reef growth 2500 years ago by observing a drastic change in the type of sediments in the sample core. . The samples showed a clear shift from coral building skeletons to non-building coralline algae rubble. This data is then correlated with the large swings in ENSO exhibiting as El Nino and La Nina events and coupling with the Intertropical Convergence Zone (ITCZ). . .
The second paper, CLIMATE, primarily focuses on interpreting other data specifically from the Vostok Ice Core study (5) and the EPICA (6) study. . There is limited field study in this paper predominantly proving the trend of carbonate accretion as CO2 rises. . Rates of change are essential in this paper as it concludes that “modern…. corals do not appear to have the capacity to adapt to sudden environmental change” (Hoegh-Guldberg et al., 2007). This research paper then models a coral dominated equilibrium versus an algal-dominated equilibrium different system and the combinations of coral cover and grazing that permit each. .
