Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.

Question

Salt is notoriously dangerous to land snails; however, some populations of aquatic, freshwater snail have brackish (or a mix of salt and fresh water) water adaptations and live in different parts of a river system. A group of scientists monitored salt concentrations in the habitats of two freshwater snail populations located nearby and recorded the data as follows (in ppt, parts per thousand):

Population 1 (Day 1): 0.1 ppt (morning), 0.0 ppt (afternoon), 0.1 ppt (evening)

Population 2 (Day 1): 0.3 ppt (morning), 0.5 ppt (afternoon), 0.2 ppt (evening)

In 3–5 sentences, 1) describe how these results show why the brackish water adaptation may be necessary, and 2) explain how to determine whether the inherited adaptation is influenced by environmental factors.

The northern hairy-nosed wombat has experienced historical population declines, though population have stabilized recently due to conservation efforts. While studying them researchers noticed the following fluctuations in (effective) population size: Year 1: 100 individuals Year 2: 90 individuals Year 3: 50 individuals Year 4: 75 individuals Year 5: 90 individuals Year 6: 95 individuals A. Given this information what is the long-term effective population size of this particular population over the six years? B. Assume that at the start of the study the researchers determined heterozygosity for this population to be 0.63 at microsatellite loci. What would you expect the heterozygosity to be at the end of the six years? (Answer part B)
Black-tailed prairie dogs used to be found in Alberta, but due to their destructive nature on farmland, the intensive efforts by ranchers and farmers to eradicate these animals has reduced the species to being found only in Saskatchewan. A farmer in Saskatchewan samples a population of black-tailed prairie dogs living in his field. Based on several samples, he finds an average of 9 prairie dogs living in an area of 7.0 m2.If he knows that his field is 4,000 m2, what is the approximate size of the prairie dog population? Select one: a. 3 111 prairie dogs b. 444 prairie dogs c. 5 143 prairie dogs d. 571 prairie dogs
In 2011, the city of Calgary had 1,096,833 people living within the city limits. Since then, there have been 245,678 births and 189,753 deaths. A total of 159,753 people moved to Calgary from other cities or countries, while only 12,354 people moved away from Calgary. How did the population of Calgary change since 2011? Express your answer using scientific notation in the form of x.yz x 10d people.

A population of 1,000 wild turkeys is studied and observed by scientists on an island. The scientists construct a study over five years to observe the temperature, amount of precipitation, daily value of berries individually consumed that were their exclusive food source, and available habitat for nesting. The scientist determined that as the climate changed, the population began to decrease. Using the Hardy-Weinberg Equilibrium as a null hypothesis, which of the following observations made by the scientists would support an associated alternative hypothesis? Due to the climate change, some birds may emigrate to a cooler location that would lead to a variation in the gene frequencies within the population. Variations in gene frequency due to advantages in natural selection would cause a greater number of males in the population to have more desirable traits. An increase in food consumption would cause the population to begin to exceed the carrying capacity that leads to a…

The neighborhood of a lake has a population of snails, which come out onto the sidewalk when the sprinklers come on, and the rest of the time they hide in the vegetation. If you catch 20, and mark them and, then, a week later, after they have had a chance to disperse into the population, you catch 15, and 6 have marks on them, what is the estimated size of the population?
Populations are unable to sustain exponential growth for very long because environments are not unlimited. Eventually growth rates are reduced by a shortage of food, space or some other factor. These factors constitute what is known as ‘environmental resistance’ and their effect upon growth may produce a logistic growth curve. The data shown in the Table below illustrate this pattern of growth for three species’ populations, each beginning with a population of 10 individuals. Table 1: Temporal changes in the numbers of individuals of three different species’ populations, observed in the wild. Time (units) 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Population 1 10 15 20 28 39 48 57 66 81 88 93 107 108 108 108 108 119 Population 2 10 11 12 14 17 19 21 25 29 33 37 41 40 43 46 49 46 Population 3 10 17 27 39 52 64 67 69 70 78 83 86 88 80 84…
In 1929, 13 white-tailed deer were introduced to an isolated island with no natural predators. A survey was conducted once a year to estimate the population of deer on the island. The table shows the deer population over the first five years on the island. The deer fed on many of the native plants found on the island, including the California false indigo, a thornless shrub that is a preferred food source on the island for deer. Based on the data, which of the following graphs correctly predicts the population of California false indigo from 1929 to 1941? Year of Survey Population of Deer 1929 13 1932 29 1935 66 1938 157 1941 398 image 1 because the California false indigo will be able to reproduce faster than it can be consumed by the deer and will be unaffected by the deer population, maintaining its current population image 2 because the increasing number of deer will help spread seeds of the plant and lead to a rise in…
