There has been various studies which relate characteristics of species to vulnerability to extinction. According to a study, long lived species having late maturation rates and slower growth rate have higher risk of getting extinct. For example, endangered H. bungaroides mature late at about 6 years of age, with long generation length of 10.4 years. On the other hand the common C. nigrescens mature early within 3 years, with shorter generation length of 5.9 years. The study concluded that species having low life histories are more vulnerable to extinction.
Vulnerability to extinction can be linked to species characteristics. Explain.
Species extinction and habitat loss! Explain how Climate Change impads vulnerable species results in the spread of invasive Species food webs. 2. Explain how these changes will affect
Community succession can occur through A. extinction of species B. evolution of members of the community C. invasion of non-native species D. all of the above
EXERCISE 18.6 How Quickly Can Humans Hunt a Species to Extinction? Name: Course: Section: Date: The moa, a giant flightless bird, was hunted to extinction on New Zealand in the early 1400s. The human population of New Zealand was no more than 2,500 at the time when the moa went extinct. We can make some simplified calculations to see how many moas were hunted per year (a) Humans first settled New Zealand and began hunting moas in 1314. The last...
4. We learned commonness and rarity in Chapter 9. Populations that are most threatened by extinction, have restricted geographic ranges, narrow habitat tolerances, and small local populations. You goal is to increase the size of the population. Search different factors to decrease vulnerability to extinction instead of using geographic ranges, habitat tolerances and local population (from books, journal articles, on-line, and etc.). Your species can be either animals or plants, or both (2.5pt).
What are the characteristics of X-linked recessive traits and X-linked dominant traits? Explain this by using examples. How do human cells compensate for the X-linked gene dosage difference in XX and XY nuclei? How are autosomal genes are influenced to sexual dimorphism?
1. The __________ group reflects the characteristics of a vulnerability that may change over time but not across user environments. a. Base Metric b. Temporal Metric c. Environmental Metric d. Impact Metric 2. The ____________ group represents the characteristics of a vulnerability that are relevant and unique to a particular organization's environment. a. Base Metric b. Temporal Metric c. Environmental Metric d. Exploit Code Maturity Metric
1. What attributes predispose individuals to vulnerability? 2. What are three enabling characteristics? 3. What is the third determinant of vulnerability?
Island species are especially vulnerable to extinction because: A. A single event like a hurricane may destroy a small island population B. The extinction of a prey species may destroy a small island population C. The introduction of a new predator may destroy a small island population D. Random fluctuations in birth and death rates may destroy the small population of an island E. All are correct
Answer the following questions about Biodiversity and Extinction Which is a more sensitive measure of species diversity - species richness or species evenness? Why? (No more than 3 sentences.) You are using giving a talk on the latitudinal gradient in species diversity using the following figure. What label would you put on the X-axis and Y axis? (list X first followed by Y, 1-5 words) 50, Explain the features of the Time-Area hypothesis that make it an explicitly "evolutionary" explanation...
What is the probability of extinction for a species of rare bird with an initial population size of 118, b = 1.39, d = 1.31. What if there were only 20 birds to start?
