Volatile Secondary Metabolites in Plant Stress Responses In 2007, researchers Casey Delphia, Mark Mescher, and Consuelo De Moraes (pictured at left) published a study on the production of different volatile chemicals by tobacco plants in response to predation by two types of insects: western flower thrips and tobacco budworms. Their results are shown in FIGURE 30.19. FIGURE 30.19 Volatile (airborne) compounds produced by tobacco plants in response to predation by different insects. Plants were untreated (C), attacked thrips (T), mechanically wounded (W), mechanically wounded and attacked by thrips (WT), attacked by budworms (HIV), or attacked by budworms and thrips (HVT). Values are in nanograms/day. Which treatment elicited the greatest production of volatiles?
Testing Biological Control Biological control agents are used to battle red imported fire ants. Researchers have enlisted the help of Thelohania solenopsae, a natural enemy of the ants. This microsporidian (Section 23.4) is a parasite that infects ants and shrinks the ovaries of the colony's egg-producing female (the queen). As a result, a colony dwindles in numbers. Are these biological controls useful against imported fire ants? To find out, USDA scientists treated infested areas with either traditional pesticides or pesticides plus biological controls (both flies and the parasite). The scientists left some plots untreated as controls. FIGURE 45.16 shows the results. FIGURE 45.16 A comparison of two methods of controlling red imported fire ants. The graph shows the numbers of red imported fire ants over a 28-month period. Orange triangles represent untreated control plots. Green circles are plots treated with pesticides alone. Black squares are plots treated with pesticide and biological control agents (parasitoid flies and a microsporidian parasite). How did population size in the control plots change during the first four months of the study?
Testing Biological Control Ant-decapitating phorid flies are just one of the biological control agents used to battle imported fire ants. Researchers have also enlisted the help of Thelohania solenopsae, another natural enemy of the ants. This microsporidian (Section 23.4) is a parasite that infects ants and shrinks the ovaries of the colony's egg-producing female (the queen). As a result, a colony dwindles in numbers and eventually dies out. Are these biological controls useful against imported fire ants? To find out, USDA scientists treated infested areas with either traditional pesticides or pesticides plus biological controls (both flies and the parasite). The scientists left some plots untreated as controls. FIGURE 45.28 shows the results. FIGURE 45.28 A comparison of two methods of controlling red imported fire ants. The graph shows numbers of imported fire ants over a 28-month period Orange triangles represent untreated control plots. Green circles are plots treated with pesticides alone Black squares are plots treated with pesticide and biological control agents (phorid flies along with a microsporidian parasite). 3. If this study had ended after the first year, would you conclude that biological controls had a major effect?
Hawaiian Honeycreeper Phylogeny The Poouli (Melamprosops phaeosoma) was discovered in 1973 by a group or students from the University of Hawaii. Its membership in the Hawaiian honeycreeper clade was (until recently) controversial, mainly because its appearance and behavior are so different from other living honeycreepers. Its particularly lacked the old tent odor characteristic of other honeycreepers. In 2011, Heather Lerner and her colleagues deciphered phylogeny of the 19 Hawaiian honeycreepers that were not yet officially declared to be extinct at the time, including the Poouli. The researchers sequenced mitochondrial and nuclear DNA samples taken from the honeycreepers, and also from 28 other birds (outgroups). Phylogenetic analysis of these data firmly establishes the Poouli as a member of the clade, and also reveals the Eurasian rosefinch as the clades closest relative (FIGURE 18.11). FIGURE 18.11 Hawaiian honeycreeper phylogeny. This cladogram was constructed using sequence comparisons of mitochondrial DNA (whole genome), and 13 nuclear DNA loci of 19 Hawaiian honeycreeper and 28 other finch species. 1. Which species on the cladogram represents an outgroup?

Sun 9. Label the archegonia in Figure 3 below. Figure 3. Marchantia archegonial head l.s. Photo by Carolyn Alling 10. Is the egg cell produced by meiosis or mitosis within an archegonium? Explain ond Obtain a prepared slide containing mature sporophytes and, using the low power lens of the microscope, find a complete sporophyte. 11. Is the sporophyte haploid or diploid? Note that the sporophyte is attached to the gametophyte by a large foot. This structure grows through the base of the venter into the storage tissue of the archegonial head. 12. What is the function of the foot? 13. Is the sporophyte an "independent" or "dependent" organism? Explain The sporophyte also consists of a stalk, or seta, and a capsule, or sporangium (see text Figure 16-8, page 371). Numerous spores and elongated elaters are enclosed by the sterile jacket layer of the capsule. The elaters have spirally arranged, hygroscopic (moisture absorbing) wall thickenings that are sensitive to very slight changes in…
