Q: Fire is an important factor in the structure of many landscapes. Identify three factors of the Mediterranean climate that causes fire to be particularly important in structuring this landscape.

Q: Flood control and channelization of the Kissimmee River of Florida
- Caused a large decrease in the wetland area of the river basin.
- Caused increases in popular game fish such as largemouth bass
- Decreased the wetland area and increased gamefish populations
- Improved the ecology of the river basin.
- Was successful and replicated in many other river basins.
A: Caused a large decrease in the wetland area of the river basin.

Q: The negative impact of fragmentation and isolation on populations can be reduced by connecting habitat fragments with corridors of similar habitat, and experimental data supports this concept.
- True
- False
A: True

Q: Hanski, Kuussaari, and Nieminen studied Glanville fritillary butterfly, Melitaea cinxia, and found what relationships regarding population size and density?
- Large patches hosted larger populations at higher densities.
- Large patches hosted larger populations but at lower densities than smaller patches.
- Small patches hosted larger populations at higher densities than large patches.
- Small patches hosted smaller populations and lower densities than larger patches.
- Patch size did not influence population density but correlated with population size.
A: Large patches hosted larger populations but at lower densities than smaller patches.

Q: A heterogenous area consisting of a mosaic of environments is a

Q: What change in eastern North America and Veluwe region of the Netherlands has been observed in the last 50 years?
- Fragmentation of forest due to increased land clearing for agriculture.
- Increases in forest cover due to abandonment of agricultural fields.
- Decreases in forest cover due to climate change.
- Decreases in wetland habitats due to riverine restoration efforts.
- Increased biodiversity due to suppression of fires.
A: Increases in forest cover due to abandonment of agricultural fields.

Q: A large value of the patch shape index, S = P/(2√πA), indicates a
- a nearly circular shape with a high perimeter to area ratio
- a nearly circular shape with a low perimeter to area ratio
- an elongated patch with a low perimeter to area ratio
- an elongated patch with a high perimeter to area ratio
- a patch with high species biodiversity
A: an elongated patch with a high perimeter to area ratio

Q: Hanski and colleagues investigating the Glanville fritillary butterfly found was association between local population extinctions and  colonizations to patch size?
- Small patches were the most likely to experience a local extinction or colonization.
- Small patches were the most likely to experience a local population extinction, but the least likely to be colonized.
- Large patches were the most likely to experience either a local population extinction or colonization.
- Large patches were the most likely to experience a colonization, but the least likely to experience an extinction.
- Large patches were the most likely to experience an extinction, but the least likely to experience a colonization.
A: Small patches were the most likely to experience a local extinction or colonization.
