A follow-up study indicated that the effect of environmental stochasticity on extinction risk was negatively correlated with body size (i.e., larger shrews were less affected by environmental variation). Does this make biological sense? Why or why not

Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.

Step 1 Environmental Stochasticity and species extinction

Environmental stochasticity refers to unpredictable spatio-temporal fluctuation in environmental conditions for example events such as floods, droughts, and other catastrophes that may affect population spatial distribution.

Stochasticity metapopulation models take into account stochasticity, which is the non-deterministic or random processes in nature. .

In one of the hypotheses that explain the extinction of the dinosaurs, the rapid climatic change produced an environmental situation with which these species could not cope. How important is the total amount of variation present in the population if the selective pressures suddenly change? Why?
Climate warming could lead to all-female populations of bearded dragons, resulting in extinction of the species. What are some other potential effects of climate warming on natural populations of organisms?
Modern humans over-eat sugar because we love it so much. One might ask, “why are we designed by evolution to love sugar when sugar is so bad for us?” How does the concept of the “environment of evolutionary adaptation” (EEA) help us explain this and some otherwise puzzling behaviors of modern humans? Please explain EEA first.
As a genetically homogeneous species, elephant seals have a diminished capacity to evolve in response to environmental changes that may occur in the future—the entire population will be affected, to about the same degree, by any adverse changes. Do you think that elephant seals, regardless of their abundance, should be considered potentially endangered for the foreseeable future? Why or why not?
On large, black lava flows in the deserts of the southwestern United States, populations of many types of animals are composed primarily of dark individuals. By contrast, on small lava flows, populations often have a relatively high proportion of light-colored individuals. How can you explain this difference?
One way to prevent a small population of a plant or animal species from going extinct is to deliberately introduce some individuals from a large population of the same species into the smaller population. In terms of the evolutionary mechanisms discussed in this chapter, what are the potential beneﬁts and drawbacks of transferring individuals from one population to another? Do you think biologists and concerned citizens should take such actions?
After a fire devastates all of the trees in a wide swath of forest, populations of a species of tree-dwelling frogs on either side of the burned area diverge and become different species. This is an example of what?
On large, black lava flows in the deserts of the southwestern United States, populations of many types of animals are composed primarily of black individuals. By contrast, on small lava flows, populations often have a relatively high proportion of light-colored individuals. How can you explain this difference?
Many species of animals make alarm calls, which warn others in their group that a predator is approaching. Alarm calls also attract the atten- tion of the predator, making it more likely that the individual making the call will be eaten. Why might natural selection favor the evolution of alarm calls in a species? How might you test that hypothesis?
If natural selection has no foresight,how can it explain features that seem to prepare organisms for future events? For example, deciduous trees at high latitudes drop their leaves before winter arrives, male birds establish territories before females arrive in the spring, and animals such as squirrels and jays store food as winter approaches.
Say that you had only the Florida example for the graph. Would it necessarily be true to claim that natural selection was acting on the beak length of the insect when the introduced host plant species became the abundant feeding site? Or could natural selection be acting on a character that is correlated with beak length? Why or why not?
After the mass extinction that occurred 65 million years ago, mammals rapidly diversified to occupy habitats that were previously unavailable to them. What concept does this illustrate? A. Adaptive radiation B. Cretaceous selection C. Reproductive isolationD. Heterozygote advantage
