To review:
The factors that may have resulted in the development of high coral reef species at the Kimbe Bay site and low at others.
Given:
Figure 1 shows the study area of the experiment in the Indo-pacific region with high coral reef species. The three sites are Kimbe Bay in Papua New Guinea (PNG), Moorea Island in French Polynesia, and Lizard Island in the Great Barrier Reef on the east coast of Australia.
Figure 1: Experimental sites across the Indo-pacific region.
Graph 1 shows the results of the number of fish species found in the coral species region. A relationship was established between the index of sensitivity and the number of coral species.
Graph 1: Relationship between the index of sensitivity and number of coral species.
Introduction:
An experiment was conducted in the three islands, Kimbe Bay (highest fish diversity), Moorea island (lowest number of fish species), and Lizard island (with an intermediate number of fish species). In the experiment, the coral diversity was manipulated and associated fish species were counted during a 12-month period. Based on this experiment, an index of sensitivity was calculated to evaluate the relationship between the number of coral species and the number of associated fish species that inhabited in the plots.

- Upper Intertidal Zone Lower Intertidal Zone Balanus balonoides Chthamalus stellatus The diagram above shows the distribution of two species of barnacle in the intertidal region of the Isle of Cumbrae, Scotland. What is the unusual and interesting pattern Connell noticed in the distribution pattern? O The two species were found together in the intertidal zone. O The two species' distributions were mixed in the intertidal zone. The two species' distributions formed horizontal bands in the intertidal zone that did not overlap. O The two species distributions formed horizontal bands in the intertidal zone with a large area of overlap where the two species were found coexisting together.arrow_forwardhow would coral bleaching affect other populations in the coral reef.arrow_forwardWhat levels caused the diversification event?arrow_forward
- please explain A drawback of the time hypothesis to explain the variation in species richness is that 1. Cannot account for algal diversity. 2. Fossils do not preserve well in the oceans. 3. Geological activity may interfere with species richness measurements. 4. It is not applicable to marine ecosystems because there was no glaciation in oceans. 5. Humans significantly modified marine environments.arrow_forwardOne direct effect of the zebra mussel invasion was a decrease in the cloudiness of the water.

- What is coral bleaching? How these phenomena affect biological diversity in marine ecosystems.arrow_forwardDescribe three kinds of benthic marine communities that use hard sub-strates and three that use soft substrates. What are the main physical factors that separate community types within each substrate category?arrow_forwardAnswer the following questuons below: 2.) How is light important to the organisms of the lower intertidal zone? 3.) What other physical factors contribute to the diversity in the intertidal zone?
