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).

To keep horseshoe crab populations stable, blood is extracted from captured animals, which are then returned to the wild. Concerns about the survival of animals after bleeding led researchers to do an experiment. They compared survival of animals captured and maintained in a tank with that of animals captured, bled, and kept in a similar tank. FIGURE 24.28 shows the results. FIGURE 24.28 Mortality of young male horseshoe crabs kept in tanks during the 2 weeks after their capture. Half the animals were bled on the day of their capture. Control animals were handled, but not bled. This procedure was repeated 8 times with different sets of horseshoe crabs. In which trial did the most control crabs die? In which did the most bled crabs die?Deathly Lamprey Repellent Predation by sea lampreys on native fishes in the Great Lakes is an ongoing problem. To help solve it, Michael Wagner and his team test methods of repelling lampreys. They carried out an experiment to investigate reports that sea lampreys detect the scent of lamprey carcasses and tend to avoid them. The researchers made alcohol-based lamprey carcass extracts, then observed what happened when lampreys were put in tanks and exposed to either this extract or to alcohol alone. FIGURE 25.6 shows their results. FIGURE 25.6 Effectiveness of carcass extracts as a lamprey repellent. Mean proportion of lampreys on the scented side of the test tank during B trials with 10 lampreys. Lampreys were placed in the tank for 20 minutes before exposure to alcohol or carcass extract and remained there for 40 minutes after exposure. The upper graph shows results with alcohol as the stimulus; the lower shows the results with carcass extracts. Bars indicate standard error. What was the lowest proportion on lampreys on the scented side of the tank when the scent was alcohol? When the scent was alcohol-based carcass extract?

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?F2 @ W 3 Which of the following things is/are true about this organism?
