Concept introduction:
The phenomenon in which the few members of a species can interbreed with one another and cause a loss in the total amount of different traits of genetics is known as bottle neck effect.

Which of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships?
A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant.
B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird.
C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators.
D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.
Changing conditions put intense pressure on organisms-some of which become extinct. For example,
of the original 62 species of honeycreeper found in Hawaii only 18 remain. Scientists have the
technologies that may allow bringing back organisms that have become extinct. This brings up ethical
questions about the cost/benefit of resurrecting extinct species and whether it is the right thing to do.
Joseph Bennett, a professor of biology at Carleton University in Ontario, wanted to determine the cost of
resurrecting and maintaining an extinct species. Since the up-front cost of resurrecting an extinct
species is very difficult to determine, the researchers decided instead to look at the cost of
reintroducing and protecting a resurrected organism in the wild. To accomplish this, the researchers
considered 70 animals from New Zealand and 29 animals from New South Wales that went extinct within
the last 1,000 years. From this list, they chose 11 New Zealand species and five NSW species that…
Allan Pounds and Kevin Anchukaitis both think only one factor - either climate change or an El Nino
event - killed the golden toad. However, might they both be right? Could it be that the dry conditions
created by the El Nino event were worsened by underlying climate change effects, so that El Nino and
climate change together caused the extinction of the golden toad in Monteverde?
Yes, the El Nino event in combination with climate change could have led to the extinction of the golden toad.
Multiple factors can influence species' extinction.
O No, only one factor - either climate change or El Nino - acting alone killed the golden toad. Species are only ever
affected by one environmental factor, never by multiple factors.

- Very few species on Earth are completely r-selected or K-selected. Many species in their natural habitats demonstrate a life strategy that ranges along a continuum between r- and K-selected strategies. Use this information to answer the 3 sub-parts. a) Sea otters are marine mammals that live in northern Pacific coasts. Typical female sea otters reach sexual maturity around 3 or 4 years of age, and they reproduce once a year, producing a single pup.Only female sea otters are tasked with raising the offspring. Mothers constantly take care of their pups until they are 8 months old, but only 25% of the pups survive past the first year. Sea otter fur was highly sought after between the 18th century and the early 20th century. Through conservation efforts, the number of sea otters increased. The current world population is estimated to be between 1 000 and 2 000 individuals, and they are considered to be endangered. Their main food source is sea urchins, molluscs, and crustaceans.

Wellsarrow_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_forward
- You are observing two different species of caterpillars feeding on green shrubs in the Sacramento Mountains. One has bright red and yellow stripes, the other is a nondescript greenish color. You hypothesize that the two species have adopted different antipredation strategies. 1) What would these two strategies be called? 2) Which species would you predict is noxious to potential predators and which species is palatable? 3) Which species would you predict would alter its behavior more in the presence of predators? Why?arrow_forwardExplain at least one (1) adaption that our species may develop to continue surviving on eartharrow_forwardWhich statement about dispersal is false?(A) Dispersal is a common component of the life cycles ofplants and animals.(B) Colonization of devastated areas after floods or volcaniceruptions depends on dispersal.(C) Dispersal occurs only on an evolutionary time scale.(D) The ability to disperse can expand the geographic distribution of a species.arrow_forward
- Create a two-part figure showing the effects of forest fragmentation on the community of small mammals relevant to Lyme disease in eastern forests. Figure A should depict the interaction network of a large forestpatch with higher species diversity. Figure B should illustrate how the interaction network and transmission of Borrelia burgdorferi are different in a small forest fragment with low species diversity than they are in largeforest patches with greater diverisity. Eastern forests are diverse communities in which many species interact with one another. Your figure will be asimplified interaction network showing some of the most important species related to the ecology of Lyme disease. Remember that your goal is to illustrate how increasing fragmentation affects forest mammal communities in a way that increases Lyme disease risk.• Choose from the following species for your figure: black-legged tick, white-footed mouse, raccoon, eastern chipmunk, gray squirrel, white-tailed deer,…arrow_forwardThe Burmese Python, an invasive species, has been introduced to the Florida Everglades, largely through release by owners who acquired the snakes from exotic pet traders. Though the Everglades are protected, pythons as predators can not be easily controlled. What can be concluded about the effect of the python population on the biodiversity of the Everglades? A. Since the Everglades are protected, python control is limited under laws that protect species in the Everglades. B. Since the python population is growing, it will eventually become a native species and will increase biodiversity. C. Since pythons prey on many species in the Everglades, resources will be more available for surviving species and fewer will be considered endangered. D. Since pythons have no predators, they are responsible for decreasing mammal population and are a greater threat to biodiversity.arrow_forwardAfter the drought of 1977, researchers hypothesized that on the Galapagos Islands’ Daphne Major, medium ground finches with large, deep beaks survived better than those with smaller beaks because they could more easily crack and eat the tough Tribulus cistoides fruits. A tourist company sets up reliable feeding stations with a variety of bird seeds (different types and sizes) so that tourists can get a better look at the finches. Which of these events is now most likely to occur to finch beaks on this island? Why? * Increased variation in beak size and shape over time No answer No change in beak size and shape over time. Evolution of yet larger, deeper beaks over time, until all birds have relatively large, deep beaks. Evolution of smaller, pointier beaks over time, until all birds have relatively small, pointy beaksarrow_forward
