Question
1. The climate envelope model assumes that an organism’s realized niche approximates its fundamental niche. True/False
2. What does the climate envelope predict about the lizards’ future range?
A) The range of S. occidentalis will expand up the mountain as temperatures increase.
B) The range of S. graciosus will shrink as temperatures increase.
C) S. graciosus will go extinct as temperatures increase.
D) Both A and B
3. Of the three assumptions of a climate envelope model mentioned in the video, which is the safest to assume in the short term?
A) Adaptation does not occur.
B) No barriers prevent dispersal.
C) Biotic interactions between species will not change.
4. Testing the thermal minimums and maximums of these species in a laboratory can measure:
A) Their realized niche
B) Their fundamental niche
C) Their optimal temperature
5. Moving the lizards to opposite elevations on the mountain most directly tests:
A) Their fundamental thermal niche
B)The effect of intraspecies competition
C) The effect of interspecies competition
D) The effect of stress from handling
6.The prediction of the mechanistic model differs from that of the climate envelope in what ways?
A) The projected range of S. occidentalis is smaller in the mechanistic model.
B) S. graciosus has a higher CtMax in the mechanistic model.
C) S. occidentalis will outcompete S. gracious across its range in the mechanistic model.
D) All of the above

You want to predict their future distributions under a projected 3°C rise in temperature. You go to the White Mountains of Arizona and conduct transect surveys for both species from the base to the summit of Green's Peak. From that data, you construct some predictive models S. occidentalis S. graciosus Directions: From your transect surveys you have found the present ranges of both these species on Green's Peak (see slide 3). First, fll in the table on slide 2. Then, use Red (S. occidentalis) and Blue (S. graciosus) brackets to predict their FUTURE distributions under a 3°C rise in temperature. Note that S. occidentalis occurs at temperatures up to 55°C Activity 2: Mcmuring Climin ad Click to add notes Slide 1 ot5 Office Theme O Type here to search 4/16/2018Explanation / Answer
1) the statement is true because every organism is suitable with its own niche where we can find..
2) the correct option is option (a) the distribution of the lizard will increase with the heat
3) the correct option is option (b) no barrier prevent dispersal
5) "the correct option is option (d) removing them will remove the intraspefic competition.
