Question
The tiger, mountain gorilla, spotted owl, giant panda, snow leopard, and grizzly bear are all endangered by human encroachment on their habitats. Why might these animals, which all have equilibrial life history traits, be more easily endangered than animals with opportunistic life history traits? What general type of survivorship curve would you expect these species to exhibit? Explain your answer.

- Wildebeest are species of antelope found in southern Africa. The wildebeest herd in Serengeti National Park, Tanzania, is the largest herbivore herd on Earth. Scientists began monitoring the sizes of the Serengeti's large mammal populations in the 1960s. Over the next few decades, they noticed something unusual: the wildebeest population was increasing at a rate much faster than before. The scientists determined that this increase was due to several factors. One factor was a vaccination program that eradicated rinderpest, a viral disease that kills wildebeest. Based on the figure, what kind of population growth model would you use to represent wildebeest (circles) populations? wildebeest zebra 1960 1970 1980 1990 2000 year Figure 1.

At the same time, human hunters migrated to the continent. Which of these most likely resulted from a combination of these two factors? an increase in the rate of large mammal extinctions a reduction in the rate of species change an increase in the amount of interspecies cooperation a reduction in the total number of small parasitic insectsarrow_forwardA particular species of butterfly is capable of surviving and reproducing both in open grasslands and in forested habitats. However, in the forested habitats this butterfly is heavily predated (eaten) by a forest bird species, so the beetle species avoids these areas and is generally found only in grasslands. Which of the following statements are true? Answer choices: A. The butterfly's realized niche includes both grasslands and forested habitats. B. The butterfly's fundamental niche includes only grasslands. C. The butterfly's realized niche includes only grasslands. D. The butterfly's fundamental niche includes both grasslands and forested habitats E. The butterfly and the forest bird species are in competition.arrow_forward
- Discuss the types of survivorship curves, explaining the life history features found in organisms possessing different types of curves. Give at least 1 example of each.arrow_forwardSuppose that researchers wanted to examine the combined effects of an introduced predator (a trout) and the trematode parasite Ribeiroia on amphibian populations. To do this, they established frog populations in each of 40 artificial ponds. Each pond was assigned at random to one of four treatments (10 ponds per treatment): 1) neither trout or parasites were added to the pond (the "No trout, no parasite" treatment); 2) no trout were added but parasites were added ("No trout, parasite added"); 3) trout were added but parasites were not added ("Trout added, no parasite"); and 4) both trout and parasites were added ("Trout added, parasite added"). Each pond contained refugia where tadpoles could avoid attack by trout, to avoid fish predators driving frog populations to extinction in an artificial pond, unlike what typically occurs in a natural pond. After two breeding seasons, the researchers estimated the density of frogs in each pond. The results are shown in the table and the figure.…arrow_forwardInsects are the largest group of animals on Earth. Insect diversity is greatest in the tropics, where habitat destruction and species extinction are occurring at an alarming rate. What biological, economic, and ethical arguments can you advance to persuade people and governments to preserve this biological diversity? Instructions:arrow_forward
- Tigers are solitary animals that require vast amounts of forest landscape as their territory to roam. In order to protect one tiger, we must conserve around 25,000 acres of forest. With poaching and deforestation threatening their survival, what are possible solutions to bring tiger populations back from the brink of extinction?arrow_forwardBirds generally have life-histories that can be placed on a fast-slow continuum. Species with fast life-histories have shorter life spans while species with slow life-histories have longer life spans. With this in mind, what contributes more to population growth for species found on each end of this spectrum, adult survival or annual fecundity, and why?arrow_forward
