The following statements are true except a. Founder-controlled communities are those in which there are species that has the ability to invade gaps and competitors that can hold the gaps against all comers during their lifetime b. Dominance-controlled communities are those in which some species are competitively superior to others so that an initial colonizer of a patch cannot necessarily maintain its presence there c. Primary successions occur in habitats where no seeds or spores remain from the previous occupants of the site; all colonization must be from outside patch d. Secondary successions occur when existing communities are disturbed but some at least of their seeds and so on remain.

Australian researchers removed a parasitic plant called mistletoe froma forest and observed the consequences. During the 3-yearexperiment, over 30% of the insect and bird species disappeared fromthe mistletoe-free forest. Another forest in which no mistletoe wasremoved saw no change in species diversity. What might the biologistsconclude from these data?
The long-leaf pine forest ecosystem once extended across 95 million acres of the southeastern US. However only 5 million acres now remain. This refers to a large reduction ina. the species rangeb a metapopulationc a mega population

Inmost ecological communities, we find:a.more rare species than moderately common or very common ones.b.more very common species than moderately common or rare ones.c. norare speciesâ€”apparently “rare” species are artifacts of incompletesampling.d.roughly equal proportions of rare, moderately common, and very commonspecies.e. more moderately common species than rare orvery common ones.
Anthropogenic Land-use. A. Human activity engineers landscapes into a highly heterogenous environments which according to the biodiversity global patterns (specie area curves) should drive up the number of species present in that landscape. Explain why this is not the case in human dominated landscapes. B. How does fragmentation drive decision making in land conservation? is there a better approach, over others, for anthropogenic landscapes? (hint -SLOSS) C. Why do mainland (continental islands) generally support greater diversity than oceanic islands? reason your opinion.
What is the key concept for this section? Whatis ecological succession? Distinguish betweenprimary ecological succession and secondaryecological succession and give an exampleof each.
In a tropical rainforest, an open gap lacking vegetation has been created by the fall of a large tree. Which of the following statements describes the characteristics of the plant species that are last to colonize this disturbed habitat? a. they have low reproductive rates and are good competitors b. they are good colonizers c. they have high reproductive rates and are poor competitors d. they are dominated by r-selected species e. they have high species diversity
What type of succession is the case study, Surtsey Island, Iceland, in the image (primary or secondary)? How do you know?
What is the differencebetween primary ecologicalsuccession and secondaryecological succession?

The most plausible hypothesis to explain why species richness is higher in tropical than in temperate regions is thata) tropical regions generally have more available water and higher levels of solar radiation.b) diversity increases as evapotranspiration decreases.c) higher temperatures cause more rapid speciation.d) tropical communities are younger.
