The extremely low precipitation of subtropical desert biomes might lead one to expect fire to be a major disturbance factor; however, fire is more common in the temperate grassland biome than in the subtropical desert biome. Why is this?
Tree Rings Reveal Droughts El Malpais National Monument, in west central New Mexico, has pockets of vegetation that have been surrounded by lava fields for about 3,000 years, so they have escaped wildfires, grazing animals, agricultural activity, and logging. Henri Grissino-Mayer generated a 2,129-year annual precipitation record using tree ring data from living and dead trees in this park (FIGURE 27.22). FIGURE 27.22 Annual precipitation record for 2,129 years, inferred from compiled tree ring data in El Malpais National Monument, New Mexico. Data were averaged over 10-year intervals; the graph correlates with other indicators of rainfall collected in all parts of North America. PDSI, Palmer Drought Severity Index: 0, normal rainfall; increasing numbers mean increasing excess of rainfall; decreasing numbers mean increasing severity of drought. A severe drougt contributed to a series of catastrophic dust storms that turned the midwestern United States into a "dust bowl" between 1933 and 1939. One of the worst population catastrophes ever recorded occurred in Mesoamerica between 1519 and a.d. 1600, when around 22 million people native to the region died. Which period between 137 b.c. and 1992 had the most severe drought? How long did that drought last?

Figure 44.12 Which of the following statements about biomes is false? Chaparral is dominated by shrubs. Savannas and temperate grasslands are dominated by grasses. Boreal forests are dominated by deciduous trees. Lichens are common in the arctic tundra.

Around 770 A. D., the Mayan civilization began to suffer a massive population loss, particularly in the southern lowlands of Mesoamerica. The El Malpais tree ring data show a drought during that time. Was it more or less severe than the dust bowl drought?

ou are on a field trip visiting a local pond. You have been tasked with identifying the different abiotic and biotic factors that affect the ecosystem. You notice a large dam blocking what used to be a stream. There are several aquatic plants and animals in the area. Fish reside in the pond, small reptiles like skinks and snakes live around fallen trees, finches and various other bird species can be found around the pond. You also find trash along the outskirts of the pond. Describe specifically how this keystone species would impact its ecosystem.
