Default please help with ecology questions

Q56. Deep sea vents are openings in the sea floor where hot water and nutrients spew out. As shown to the right, they have a rich community of species. However, individual vents often become plugged up, while new vents can appear in far flung parts of the ocean. Which of the following would species that live in these vents need to be especially good at?



Dispersal
Intrinsic growth
Source-sink dynamics
Patch occupancy

Q57. Approximately what patch occupancy rate would you expect in a metapopulation with a colonization rate of 1.5 and an extinction rate of 0.6?

Q58. Roads often decrease dispersal rates for animals and can divide patches in two. How might these consequences of building roads affect the survival of a metapopulation?

Roads should generally increase metapopulation survival by dividing patches and thereby creating more potential populations.
Roads should generally increase metapopulation survival by reducing dispersal, which increases survival of individual patches.
Roads should generally decrease metapopulation survival by reducing dispersal, which decreases recolonization of patches.
Roads should generally decrease metapopulation survival by dividing patches, which increases immigration rates.

Q59. For many years, the conservation community debated whether, with a given amount of funding, it would be better to conserve one large patch of land or several smaller patches. Describe situations in which each of those options might be better, justifying your answer based on metapopulation theory.
