Study Finds Aardvarks Suffering as African Climate Heats Up Little is known about Africa's elusive aardvarks, but new research says they are vulnerable to climate change like many other species. Hotter temperatures are taking their toll on the aardvark, whose diet of ants and termites is be coming scarcer in some areas because of reduced rainfall. Drought in the Kalahari Desert killed five out of six aardvarks that were being monitored fora year, as well as 11 others in the area. The aardvarks' body temperatures plummeted during the night because they were not getting enough energy from diminished food sources. They tried to conserve energy by looking for insects during the warmer daytime, but their efforts to adapt could not save them. Researchers said some birds, reptiles and other animals use aardvark burrows to escape extreme temperatures, reproduce, and hide from predators. They could have fewer refuges available if aardvark populations shrink because of rising temperatures, they said. The aardvark, which lives in many parts of sub-Saharan Africa, is identified as an animal of"least concern" on an international "red list" of threatened species. There are no indications that the population is changing significantly in southern Africa, though it is speculated that numbers may be declining elsewhere because of habitat destruction, the bushmeat trade and other factors. which of the following best identifies the author's claim? Which of the following statements best explains the changes in the size and composition of the population of finches after the drought quizlet?Which of the following statements best explains the changes in the size and composition of the population of finches after the drought? The total number of finches in the population decreased, and the larger-beaked finches were more successful in the drier environment.
Which of the following statements about biodiversity is correct?Detailed Solution. The correct answer is More than 100 hotspots of biodiversity are identified in the world. It refers to the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem levels.
Which of the following was the average beak size of finches on the island of Daphne Major in 1976?In the summer of 1976, there were 751 finches on Daphne Major when the Grants left the island. The 1976 medium ground finch population had an average beak depth of 9.65 mm and an average beak length of 10.71 mm.

Highly specialized species tend to evolve on islands because of the environmental conditions and resource availability.
