- In the short term what willhappen to the levels aboveand below a population ofsecondary consumers of anumeric pyramid if a largenumber of individuals fromthis population dies?Age structure diagrams for two hypothetical human populations are shown below. Describe the growth rate of each population and discuss the current and future social and economic problems that each is likely to face.The maximum growth rate characteristic of a species is called its _________. a. limit b. carrying capacity c. biotic potential d. exponential growth pattern
- What if we were able to restore some critical salmon habitat, like the forests surrounding the spawning streams? To test this restoration, increase K to 40,000 fish. What would that do to the MSY value? [ Select ] Does this mean you would be able to harvest more or less fish? [ Select ]What is often true of a population of organisms with a type IIl suvivorship curve? they produce few offspirng and invest more energy in each offspring O they produce more offspring and invest little energy in each Othey have low death rates during early life stages O they are equally likely to die at any ageWhat is often true of a population of organisms with a type Il suvivorship curve? they produce few offspirng and invest more energy in each offspring they produce more offspring and invest little energy in each they have low death rates during early life stages they are equally likely to die at any age

- A fishprint provides a measure of a country’s fish harvestin terms of area. The unit of area used in fishprint analysisis the global hectare (gha), a unit weighted to reflect therelative ecological productivity of the area fished. Whencompared with the fishing area’s sustainable biocapacity (itsability to provide a stable supply of fish year after year,expressed in terms of yield per area), its fishprint indicateswhether the country’s annual fishing harvest is sustainable. The fishprint and biocapacity are calculated using thefollowing formulas:Fishprint in (gha) = metric tons of fish harvestedper year/productivity in metric tons per hectare ×weighting factorBiocapacity in (gha) = sustained yield of fish in metrictons per year/productivity in metric tons per hectare ×weighting factorThe following graph shows the earth’s total fishprint andbiocapacity between 1950 and 2000. Study it and answerthe following questions: If biologists determine that this country’s sustainedyield of fish is…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?HXON E Priv You are starting a fishery with a limited number of identical natural ponds. Your goal is to raise the largest yield (Total Fish) per pond without adding feed to the water. The natural ponds already have food sources whose identity isn't necessary to answer this question. To determine the best fish or combination of fish to farm, you add equal amounts of different fry (young fish) to each of your ponds: Only Tilapia, Only Catfish, Only Trout, Tilapia and Trout, Tilapia and Catfish, and Trout and Catfish. At the end of the year, you count the numbers of adult fish raised and enter them into a data table: Pond # of Tilapia # of Catfish # of Trout Total fich Tilapia Only 45 0 0 15 45 Catfish Only 0 40 0 40 Trout Tilapia and Tilapia and Catfish and Only Trout Catfish Trout 0 0 50 50 20 0 20 40 35 30 0 65 0 40 50 90
