Introduction 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 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?
Old People e = 100 calories λ = 10 per night h = 2 hours Middle Aged People e = 400 calories λ = 20 per night h = 5 hours Young Adults e = 300 calories λ = 10 per night h = 2.5 hours Suppose that the organism need 1000 calories per night. - Which food item should the organism prefer, and which ones would you expect them to eat on a regular basis? Explain why and show calculations. - Explain marginal value theorem, and how it might relate to an organisms foraging decisions. - λ for Old People should increase in the coming years. How could that affect this organisms feeding on humans?
