4 points each. You study different ground squirrel populations and find that, the more unpredictable the length of the winter is, the fewer offspring they have each year. To estimate ground squirrel numbers, you conduct capture-recapture studies each year. A predator that feeds on ground squirrels does not take many of them when they are rare, but switches to feeding on them when they become more common because it develops a search image for them. Ground squirrels and marmots are both rodents that occur in the mountains.
Marmots are much bigger than ground squirrels.
Where you have been studying marmots, they typically produce litters of 4 offspring. When you move some of these marmots to a different climate, they start producing litters of 6 offspring. Briefly state one way in which an ectothermic species could regulate its body temperature at a different temperature from the air temperature 11. Briefly state Liebig's Law of the Minimum. The carrying capacity is 300, r m is equal to 0.4.
