- EVOLUTION CONNECTION The fossil record indicates that therehave been five mass extinction events in the past 500 millionyears (see Concept 25.4). Many ecologists think we are on theverge of entering a sixth mass extinction event. Briefly discussthe history of mass extinctions and the length of time it typicallytakes for species diversity to recover through the process ofevolution. Explain why this should motivate us to slow theloss of biodiversity today.Mountain gorillas are a highly endangered primate species, with 800 or so individuals surviving in the two remaining populations. A recent sampling of mountain gorilla genomes revealed a very low level of genetic diversity. Explain why a decline in genetic diversity often accompanies a decline in population size.Iguana Decline In 1987, Martin Wikelski began a long-term study of marine iguanas in the Galpagos Islands. He marked iguanas on two islandsGenovesa and Santa Feand collected data on how their body size, survival, and reproductive rates varied over time. He found that because iguanas eat algae and have no predators, deaths usually result from food shortages, disease, or old age. In January 2001, an oil tanker ran aground and leaked a small amount of oil into the waters near Santa Fe. FIGURE 44.3 shows the number of marked iguanas that Wikelski and his team counted in their study populations just before the spill and about a year later. FIGURE 44.3 Shifting numbers of marked marine iguanas on two Galpagos islands. An oil spill occurred near Santa Fe just after the January 2001 census (orange bars). A second census was carried out in December 2001 (green bars). Which island had more marked iguanas at the time of the first census?
- EVOLUTION LINK Competition is an important part of Darwins scientific theory of evolution by natural selection, and the evolution of features that reduce competition increases a populations overall fitness. Relate this idea to character displacement and resource partitioning in Darwins finches.Iguana Decline In 1987, Martin Wikelski began a long-term study of marine iguanas in the Galpagos Islands.

How much did the population size on each island change between the first and second census?Iguana Decline In 1987, Martin Wikelski began a long-term study of marine iguanas in the Galpagos Islands.

A second census was carried out in December 2001 (green bars). Wikelski concluded that changes on Santa Fe were the result of the oil spill, rather than sea temperature or other climate factors common to both islands. How would the census numbers be different from those he observed if an adverse event had affected both islands?

Numbers of the one surviving species, the kereru (Hemiphaga, novae seelandine), are declining rapidly due to habitat loss, poaching, predation, and interspecies competition that wiped out the other native birds. The keruru is the only remaining dispersal agent for several native tress that produce big seeds and fruits, mainly because it is the only remaining species that can swallow big fruits (left) and expel big seeds whole. One of these trees, the puriri (Vitex lucens), is New Zealands most valued hardwood. Explain, in terms of natural selection, what would happen to puriri trees in New Zealand if the kereru becomes extinct.The Barton Springs salamander is an endangered species found only inthree adjacent springs in the city of Austin, Texas. There is growingconcern that a chemical spill on a nearby freeway could pollute thespring and wipe out the species. To provide a source of salamanders torepopulate the spring in the event of such a catastrophe, a proposal hasbeen made to establish a captive breeding population of the salamanderin a local zoo. You are asked to provide a plan for the establishment ofthis captive breeding population, with the goal of maintaining as muchof the genetic variation of the species as possible. What factors mightcause loss of genetic variation in the establishment of the captivepopulation? How could loss of such variation be prevented? With theassumption that only a limited number of salamanders can bemaintained in captivity, what procedures should be instituted to ensurethe long-term maintenance of as much variation as possible?
- The long-leaf pine forest ecosystem once extended across 95 million acres of the southeastern US. However only 5 million acres now remain causing major declines in the Gopher tortoise population. Given this, what is expected to happen to overall diversity of species that depend on Gopher Tortoise burrows?a. increaseb. decreasec. stay the sameIntroduction The Rock Pocket Mouse The rock pocket mouse, Chaetodipus intermedius, is a small, nocturnal animal found in the deserts of thesouthwestern United States. Most rock pocket mice have a sandy, light-colored coat that enables them to blendin with the light color of the desert rocks and sand on which they live. However, populations of primarily dark-colored rock pocket mice have been found living in areas where the ground is covered in a dark rock calledbasalt caused by geologic lava flows thousands of years ago. Scientists have collected data from a population ofprimarily dark-colored mice living in an area of basalt called the Pinacate lava flow in Arizona, as well as from anearby light-colored population. Researchers analyzed the data from these two populations in search of thegenetic mutation responsible for the dark coat color. Their analyses led to the discovery of a mutation in theMc1r gene that is involved in coat-color determination. The MC1R Gene Two pigments…The Gulf of St. Lawrence is home to the beluga whalesThere once were thousands of belugas in this popula tion, but now there are fewer than 1000 whales.
