Listen to part of lecture in a biology class.
disscussion discussion, we'll review the case study on how some animals has behaviorly behaviorally adapted to their environments. Now you had to read about two animal species, the east marment Eastern marmot and the olymlic marment Olympic marmot. Marments Marmot are robatent rodents. There're They are large ground scrolls squirrels, about the size of ever tells an average house cat. And they live in a ridia variety of habitats. And even though they spent spend significant portion of the year hiborlating hibernating, according to this case study, marments marmots are still considered excellent subjects for animal behavioral studies. Why is that?
Well, when they are not
hiborlating hibernating, you can find them in open areas. And they are pretty active during day, which makes them easy to observe right?
Uh-ha....So first let's disscuss the
east marment Eastern marmots. They was i??? reside throughout the eastern region of the north of America . Was there Where there is a temoprary temperate climate , was where the growing season lasts for least 5 months of the year, which is when they do all their other planting mating, playing and eating.
Oh, I see. At first I wasn't sure what growing season mean? Just from the reading, but now I get it. It's
the month time that amount of time it takes for them to grow, right? So, it would be five months?
Umm? Oh, uh...I'm sorry, but no. It
is has nothing to with that. It's not about the time that it takes for eastern mamets Eastern marmots to grow. It's when the food is available. That is one when it's not covered in slow and there is no froster frost covering the grass and, umm, vegetate vegetative parts of plant's ob?? herbs and flowers that ??? marmots like to eat. So growing season refers to the availability of the food day they eat, OK? So, now, how do would you describe the eastern marmets marmots' social habbits?
there're they are really teretorial territorial, and lawnders loners, and just so aggressive, even with other eastern marmets marmots. And their meeting rational was just so, impersional. mating ritual is just so impersonal. UnHa....Uh-ha? Now when their they emergen emerge in the spring from hibernation, the meeting prosses mating process begins. For then them, well, they come to get together to the met mate and then go seprate separate ways. Then about six ty to eight weeks after birth, the offspring leave their mothers.
Really? Just six weeks? Is that possible for the offspring to make their own
servie on so young?
Well, it's not
??? as if they aren't ready for the real world, because they are. Remember, they matural mature quickly in and the weather's nice. Also, they living live in open fields where 's there is lots of atable edible vegetation. So roughly 6 weeks after birth, eastern marmets marmots are just old enough to take their chances of their surviving in the temporary temperate environment. So, how does this relate to their behavior?
Oh, I get it. Since the
climates are climate's not too bad, the eastern marmets marmots don't have to rely on each other too much. And they really don't need to stay together as a family to survive either.
Unhuh... And in contrast, the olympic
marmets marmots, what about them?
Well, they live together as a family, and take care of their young until they are at least 2 years old. They're really friendly with each other. And what I really like, is that, they even have greeting ceremonies. And
there're they are not at all grassive aggressive until terrortorial and territorial like the Eastern marments marmots. So....Um...They're social behaviors, So their social behavior is so different from Eastern marments marmots because of the climate were where they live. That's seem so bizzard bizarre.
Well, the olympic
marments marmots and ??? inhabit meadows high in the Olympic Mountains where the weather for the ?? conditions are much hasher harsher. So there's a lot more weden wind and slow. The growing season only lasts about 2~3 month. So in that mush much shorter periond period of time all the olympic marmets marmots meailing male and female eat, play, work, and ??til nurture the young together.
Because the climate is so harsh,
corporation in creases cooperation increases the survival right rate of the olympic marmets marmots. They keep their young at home until they are physically able to survive on their own. This could explain why the social behavior of the olympic marmets marmots in so aren't like unlike that of that eatern marmets marmots.
What is the main topic of the lecture?

- concern 关注的东西（这么翻译感觉不太对劲）（但是口语中，一般在上课的时候，是特指某个学生提问的东西，你可以理解为他关注的东西）（但是老师必须To address the student's concern）（如果不清楚这个用法的话，最后一题应该做不对）（反正我是做错了）
