- Two ecologists, Robert H. MacArthur and Edward Wilson, studied how organisms immigrate to islands and how their numbers change after colonization. They developed the island biogeography model to explain the composition and diversity of island species. The graph below shows the number of species versus the size of the Caribbean island: Number of Species 1,000 100 1 Redona 10 SPECIES BY AREA Saba Puerto Rico: Monserrat 100 1,000 Hispaniola Jamaica 10,000 Island Size in Square Kilometers Cuba 100,000 1,000,000 a. Use the Species by Area graph and your knowledge of how organisms can immigrate to answer the following: i. Identify the likely scientific question being investigated in the study. ii. Describe the relationship between species number and island size observed in the data. iii. Explain how the experiment results would change if the islands had frequent ships that docked on them from distant bodies of water. b. Scientists have found that most species on the same continent are more…arrow_forwardWhich of the following is not true of a population of largepredators in a small reserve?a. The species may disappear from the reserve.b. The species will probably undergo a populationexplosion.c. The species will probably lose genetic diversity.d. The species may overeat its prey, causing a reduction inprey population.arrow_forwardTwo islands in the Pacific Ocean are of equal size but differ in their distance from the mainland. Island C is 5 km from the mainland, while Island D is 50 km away. According to island biogeography theory, how would the extinction rates on these islands compare and why? Group of answer choices: A. Island D would have higher extinction rates because its greater distance from the mainland makes it harder for species to recolonize after local extinctions, reducing species turnover B. Both islands would have similar extinction rates because island size, not distance from the mainland, primarily determines extinction rates C. Island C would have lower extinction rates due to its smaller distance from the mainland, allowing easier recolonization and rescue effects D. Island C would have higher extinction rates due to its proximity to the mainland, which increases competition and predator pressure from mainland speciesarrow_forward
- Consider an ecological network consisting of three interconnected habitats (A BCA). Ecologists want to model the occupancy dynamics of a particular species "Species" across these habitats over time using a discrete time discrete state stochastic process. State Space: State 0: Species X is absent from all habitats. State 1: Species X is present in Habitat A State 2 : Species X is present in Habitat B. State 3: Species X is present in Habitat C. State 4: Species X is present in Habitats A&B State 5: Species X is present in Habitats A&C. State 6: Species X is present in Habitats B&C. State 7: Species X is present in All Habitats. Transition Probabilities: Rule 1: The probability of colonizing an adjacent habitat is 0.2. Rule 2: The probability of extinction from a habitat is 0.15. Rule 3: The probability of recolonization of a random habitat is 0.1 A) Draw a schematic diagram of the Markov Process illustrating states and transitions. Define the transition rate matrix forthis discrete time…arrow_forwardThe figure below shows the growth of two species in two habitats, both when the other species is present and when it is absent. What kind of interaction is occurring between these two species? (Consider both habitats, not just the interaction within one particular habitat.) Answer choices: A. Mutualism B. Conditional C. Commensalism D. Competition E. Parasitismarrow_forwardThe table below shows the size of species A and B populations that live on a small island near Philippine.a) State how the information in the table can be used to determine thatthe species B is the predator.b) Briefly explain TWO (2) possible ecological reasons, other than humanactivity, for the change in species A population between 1985 and 1990.c) Name TWO (2)limiting factors that keep the species B population sizefrom growing any larger.arrow_forward
- Use the Shannon-Weiner Diversity equation to calculate diversity (H). Which treatment (predator enclosure, no predator enclosure) is more diverse? Why do you think this is the case? Predator Enclosure: Species Number A 5 B 1 C 4 D 2 E 12 No Predator Enclosure: Species Number A 7 B 9 C 17 D 3arrow_forwardUsing the community assembly theory, provide a framework or explanation on: How do some exotic species outperform locally-adapted native species? Cite specific example(s).arrow_forwardYou are comparing species diversity between four different habitats: which of the following habitats is the most diverse? Habitat A has 15 species total, with approximately equal representation across all species Habitat B has 15 species total, and is dominated by two of its fifteen species Habitat C has 3 species total, with approximately equal representation across all species Habitat D has 3 species total, and is dominated by one of its three species Habitats A and B are equally diversearrow_forward
- Data shown in this figure describes the species richness of mammals and birds among a variety of Sky islands. Which of the following best fits the correlations represented in the graphs? 1) number of individuals increases with area and decreases with isolation 2) species richness increases with area and decreases with isolation 3) species diversity varies depending on area and isolation? Follow up question which model of species distribution and abundance does this data support? 1) Species area relationship 2) species accumulation curve 3) island-biogeography 4) rapoport’s rulearrow_forwardThe Canary Islands are a volcanic island chain off the western coast of Africa with a larger percentage of specialist species than generalist species. If an invasive species is introduced to one of the Canary Islands, which of the following represents an immediate impact? (NOTE: a specialist species has a narrow ecological tolerance, while a generalist has a wide ecological tolerance) The populations of the invasive species on the Canary Islands will decrease as predation increases. The population of the invasive species on the Canary Islands will decrease because they were outcompeted by native specialist species. The populations of both the invasive species and the specialist species on the Canary Islands will remain the same as a result of resource partitioning. The populations of the specialist species on the Canary Islands will decrease as competition for resources increases.arrow_forwardTo determine: The way in which habitat fragmentation contributes to declining biological diversity.arrow_forward
